Wheat flour is an excellent source of complex carbohydrates. Other than gluten flour, all types of wheat flour derive at least 80 percent of their calories from carbohydrates. Depending on the flour type, the percent of calories from protein ranges from 9 to 15 percent, except from gluten, which has a 45 percent protein content. Calories from fat are never more than 5 percent.



In addition, wheat flour provides from 3 g (cake flour) to 15 g (whole-wheat flour) of dietary fiber per 1-cup serving. Wheat flour contains B vitamins, calcium, folacin, iron, magnesium, phosphorus, potassium zinc and other trace elements, and minimal amounts of sodium.



Wheat is the most important cereal crop in the world and ubiquitous in our culture. Bread, pasta, bagels, crackers, cakes, muffins and other wheat containing products line our supermarket shelves and fill our grocery baskets. It is luck for us that this popular grain is available throughout the year.



Classes used in the United States are



Durum - Very hard, translucent, light colored grain used to make semolina flour for pasta.

Hard Red Spring - Hard, brownish, high protein wheat used for bread and hard baked goods.

Hard Red Winter - Hard, brownish, very high protein wheat used for bread, hard baked goods and as an adjunct in other flours to increase protein.

Soft Red Winter - Soft, brownish, medium protein wheat used for bread.

Hard White - Hard, light colored, opaque, chalky, medium protein wheat planted in dry, temperate areas. Used for bread and brewing

Soft White - Soft, light colored, very low protein wheat grown in temperate moist areas. Used for bread.

Hard wheats are harder to process and red wheats may need bleaching. Therefore, soft and white wheats usually command higher prices than hard and red wheats on the commodities market.



Wheat, in its natural unrefined state, features a host of important nutrients.



Therefore, to receive benefit from the wholesomeness of wheat it is important to choose wheat products made from whole wheat flour rather than those that are refined and stripped of their natural goodness.



The health benefits of wheat depend entirely on the form in which you eat it. These benefits will be few if you select wheat that has been processed into 60% extraction, bleached white flour. 60% extraction - the standard for most wheat products in the United States, including breads, noodles and pastas, baked goods like rolls or biscuits, and cookies - means that 40% of the original wheat grain was removed, and only 60% is left. Unfortunately, the 40% that gets removed includes the bran and the germ of the wheat grain - its most nutrient-rich parts. In the process of making 60% extraction flour, over half of the vitamin B1, B2, B3, E, folic acid, calcium, phosphorus, zinc, copper, iron, and fiber are lost.



Since 1941, laws in the United States have required "enrichment" of processed wheat flour with vitamins B1, B2, B3 and iron in response to the problems created by 60% extraction. Although not nearly as much of these B vitamins and iron are replaced as are removed from 60% extraction flour, "enriched" seems an odd word to describe this process. If you select 100% whole wheat products, however, the bran and the germ of the wheat will remain in your meals, and the health benefits will be impressive! Our food ranking qualified whole wheat (in its original non-enriched form) as a very good source of dietary fiber and manganese, and as a good source of magnesium.



Bran is made up of the outer layers of the wheat kernel. Bran is used in whole wheat flour. It is also used in breakfast cereals.



The germ is tiny - about 2 1/2% of the whole wheat kernel. The germ is the part that will sprout and grow into a new wheat plant if the kernel is planted. Wheat germ is sold in grocery stores and food markets. Whole wheat flour also contains wheat germ.

Vitamin B3



Also called Nicotinic Acid, Niacinamide, Nicotinic.



Acts as a co-enzyme in the release of energy from carbohydrates. Also needed to help breakdown fats and proteins. Aids in formation of red blood cells.

Since the 1950's doctors have used nicotinic acid to treat high cholesterol. Niacin is the only drug available that both substantially lowers the "bad" lipids (LDL), and increases the "good"(HDL) cholesterol. The reason this vitamin is not in the forefront of cholesterol therapy is because many people treated with high doses of niacin experience bothersome side effects such as; facial flushing, nausea, stomach pain, diarrhea and much more serious, liver damage.



Milk, eggs, meats (especially liver), chicken, fish, and most other protein-rich foods contain a significant amout of niacin. Also in smaller amounts in coffee and tea.



Dificiency is very rare in modern countries. Symptoms include: Pellagra (diarrhea, dermatitis, and dementia) Less severe symptoms of deficiency include irritability, loss of appetite, weekness and swollen tongue.

iron, iron sulfate, Used in the food industry as a carrier for iron.



Iron in the body works with proteins that release energy in metabolism such as hemoglobin, which carries oxygen in the blood stream. Also involved in the making of ammino acids, hormones, and neurotransmitters.

Iron can be found in meats, poultry, and fish and many fortified foods. Fruits, vegetables and juices also provide some iron.

Iron deficiency symptoms include; anemia, inability to concentrate, weakness, fatigue, pallor, being out of breath after small exertion, cold hands and feet. Some people may develop a smooth round tongue, and have difficulty swallowing.



Symptoms of overload include: nausea, vomiting, diarrhea, rapid heartbeat, dizziness, shock and even death.



***Parents should be warned that iron supplements and multivitamins containing iron are the second most common cause of poisoning in young children in the U.S. (Aspirin is the first) The lethal dose of ferrous sulfate for a 2-year-old is only 3g.***

Vitamin B-1, Perfectly safe, despite adding minuscule amounts of nitrate to our food.

Vitamin B2, or riboflavin, is required to complete several reactions in the energy cycle. Reddening of the lips with cracks at the corners of the mouth, inflammation of the tongue, and a greasy, scaly inflammation of the skin are common symptoms of deficiency.Riboflavin (B2)- Classic riboflavin deficiency involves the lips, tongue, eyes, skin and nervous system. Vision changes, cheliosis (tiny lesions in the mouth or cracks in the corners of the mouth) tongue inflammation and discomfort eating or swallowing.



Riboflavin?s role in the body involves the metabolism of fats and proteins. Enzymes influenced by riboflavin are absolutely necessary to transport oxygen to the cells. A decrease in this vitamin can result in fatigue. New research indicates that migraine headache sufferers may benefit by riboflavin. 400mgs.day have been shown to lessen the incidence of migraines.



Required for red blood cell formation, antibody production, cell respiration and growth. Important for good muscle tone. Involved in metabolism of protein, protein fats, and carbohydrates. Necessary for good vision, skin, hair and nails.

Folic acid is the synthetic form of the B vitamin folate. Folic acid is necessary for the synthesis of nucleic acids and the formation of red blood cells. Folic-acid deficiency most commonly causes folic-acid-deficiency anemia. Symptoms include gastrointestinal problems, such as sore tongue, cracks at the corners of the mouth, diarrhea, and ulceration of the stomach and intestines. Large doses of folic acid can cause convulsions and other nervous-system problems.

The Food and Drug Administration (FDA) regulations require enriched grain products to contain this essential vitamin.



Current studies have discovered a link between folic acid and brain function in older people. The study divided 818 people ages 50 to 75 to take either a vitamin containing 800 micrograms of folic acid a day, or a dummy pill, for three years.



On memory tests, the supplement users had scores comparable to people 5.5 years younger, Durga said. On tests of cognitive speed, the folic acid helped users perform as well as people 1.9 years younger.

Cornstarch, or cornflour, is the starch of the maize grain, commonly known as corn. It is also ground from the endosperm, or white heart, of the corn kernel. It has a distinctive appearance and feel when mixed raw with water or milk, giving easily to gentle pressure but resisting sudden pressure. It is usually included as an anti-caking agent in powdered sugar (10X or confectioner's sugar). For this reason, recipes calling for powdered sugar often call for at least light cooking to remove the raw cornstarch taste.



Cornstarch is often used as a binder in puddings and similar foods. Most of the packaged pudding mixes available in grocery stores include cornstarch. Cornstarch puddings may be easily made at home, benefiting from the use of a double boiler. The most basic such pudding may be made only from milk, sugar, cornstarch and a flavoring agent.



It is also used as a thickener in many recipes. Cornstarch is best dissolved in cold water, as it forms obstinate lumps when mixed with warm or hot water.



Cornstarch also has many uses in the manufacturing of environmentally-friendly products. For example, in 2004, the Japanese company Pioneer announced a biodegradable Blu-Ray disc made out of cornstarch.



Cornstarch has been used as a replacement for talcum powder by some.



Due to cross contamination, wheat may be present. Read food label carefully to ensure it is Gluten Free.

Corn starch does not trigger the autoimmune response in celiac disease. It contains a form of gluten (a type of combined grain protein), but not the same form as wheat, barley, rye, kamut, spelt, and triticale. ??If the corn starch is not contaminated, it is safe for celiacs

Soybean(s) Oil Partially Hydrogenated

Soybean Oil by itself is the 19% of oil extracted from the soybean. Partially hydrogenated is when hydrogen gas is pumped into the oil to fill in the unsaturated fat (“good fats”) bonds. However, through partial hydrogenation, the soybean oil takes a stiffer texture and the natural omega-3 fatty acids levels seen in natural soybean oil are lowered. This version of oil is therefore unhealthier to the consumer because of its unnatural use of hydrogenation which forms trans-fats that the body cannot breakdown. Trans-fats are solid fats produced from oil by unnatural methods and interfere with metabolic processes such as increasing LDL or “bad cholesterol.” Partially hydrogenated oils have a tendency to be used by food companies because of its cheapness, stability, improved texture, and ability to oxidize to provide a longer shelf life. People who are allergic to soy must be careful when reading the food labels for soybean oil. Consumption of soybean oil by those who are allergic to it can lead to discomfort or a more harmful reaction if not aware. Many of the essential fatty acids, antioxidants, and other positive components of the oil are lost through this process.

Salt is one of the most ubiquitous food ingredients around. Those who think of salt only as something used to perk up flavor might wonder what could possibly give this ingredient the level of importance it has gained through the ages. In reality, there is much more to this crystalline cube than first meets the eye.



Besides enhancing taste, salt has several other functions in food products. It acts as an antimicrobial or microbiological control agent. It contributes to certain chemical reactions that create a wide variety of food characteristics.



Sometimes the terms "salt" and "sodium" are used interchangeably, but technically this is not correct. "Salt" is sodium chloride. By weight, it is 40 percent sodium and 60 percent chloride.

Most foods and tap water contain sodium and chloride. Sodium is an essential nutrient, a mineral that the body cannot manufacture itself.

Because of sodium's importance to your body, the excretory and nervous systems guard against under-consumption of salt, which is a threat to your body's nerves and muscles. Other ions such as calcium, magnesium, and potassium are also very important. Concentrations of these ions are held in narrow ranges by the kidney.



The association between eating salt and the risk of blood pressure increasing is difficult to quantify. Some people are sensitive to changes in salt intake whereas others can adjust so that blood pressure does not rise at all.



Americans typically consume 4,000-8,000 mg each day, well above their daily needs. A goal for moderation for all adults, (including pregnancy and lactation) is approximately 2,400 mg of sodium per day.

Whey or milk plasma is the liquid remaining after milk has been curdled and strained; it is a by-product of the manufacture of cheese or casein and has several commercial uses. Whey is used to produce ricotta and gjetost cheeses and many other products for human consumption. It is used as an additive in many processed foods, including breads, crackers and commercial pastry. In addition, whey is used as an animal feed. Whey proteins mainly consist of a-lactalbumin and ß-lactoglobulin. Depending on the method of manufacture, it may also contain glycomacropeptides (GMP).



The whey protein separated from this mixture is often sold as a nutritional supplement. Such supplements are especially popular in the sport of bodybuilding. Liquid whey contains lactose, vitamins, and minerals along with traces of fat. Researchers at Lund University in Sweden discovered that whey appears to stimulate insulin release. Writing in the American Journal of Clinical Nutrition they also discovered that whey supplements can help regulate and reduce spikes in blood sugar levels among people with type 2 diabetes by increasing Insulin secretion.

The exact components of milk vary by species, but it contains significant amounts of saturated fat, protein and calcium. These amounts are not large in comparison to other foods rich in them, including coconuts, fish, and kale respectively, because milk is predominantly composed of water. Aquatic mammals, such as seals and whales, produce milk that is very rich in fats and other solid nutrients when compared with land mammals' milk.



Most milk packs a nutritional punch and contains protein, calcium, phosphorus, vitamins A and D, LACTOSE (milk sugar) and riboflavin. On the minus side, milk's natural sodium content is quite high. Most milk sold in the United States today is PASTEURIZED, which means the microorganisms that cause diseases (such as salmonella and hepatitis) and spoilage have been destroyed by heating, then quick-cooling, the milk. Pasteurization eliminates the possibility of disease and gives milk a longer shelf life. Most commercial milk products have also been HOMOGENIZED, meaning that the milk fat globules have been broken down mechanically until they are evenly and imperceptibly distributed throughout the milk. The end result is that the CREAM does not separate from the milk and the liquid is uniformly smooth.



Cow's milk is generally available in several varieties. In some countries these are:



Full cream (or "whole" in US, "homo milk" in Canada & some US dairies, about 3.25% fat)

Semi-skimmed ("reduced fat" or "low fat", about 1.5-1.8% fat)

Skimmed (about 0.1% fat)

Milk in the U.S. and Canada is sold as:



Whole varieties

2% (reduced fat)

1% (low fat)

<0.5% (very low fat)

Skim (nearly no fat) or fat free

In the United States, skim milk is also known as "fat free" milk, due to USDA regulations stating that any food with less than ½ gram of fat per serving can be labeled "fat free".

Natural food enzymes that, when taken with gassy foods, help reduce flatulence-sometimes even stopping it before it begins. Gas-producing foods like beans, broccoli, cabbage, cauliflower, grains and onions cause trouble because they contain hard- or impossible-to-digest complex sugars (see CARBOHYDRATE) that ferment in the large intestine. Digestive enzymes help break down these complex sugars into simple sugars that are more easily digestible.



Proteins produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme has a specific function. The two classes of enzymes are metabolic and digestive. Metabolic enzymes catalyze the many chemical reactions in the body. Digestive enzymes are responsible for breaking down food into smaller absorbable units. There are specific enzymes that break down protein, fat and carbohydrate; these are protease, amylase and lipase respectively.

This popular CHEESE originated in the village of Cheddar in the Somerset region of England. It's a firm, cow's-milk cheese that ranges in flavor from mild to sharp, and in color from natural white to pumpkin orange. Orange cheddars are colored with a natural dye called ANNATTO. Cheddar is used for out of hand eating, as well as in a panoply of cooked dishes including casseroles, sauces, soups and so on.



the fat content of cheeses, check the label for a percentage, followed by the letters M.F. (milk fat). With cheddars, the milk fat content is usually 31% M.F. Low Fat natural cheddars are usually 20% M.F.



Cheddar Cheese is a nutritious and excellent source of calcium, amino acids, and vitamins C, D and E.

Monosodium Glutamate

Monosodium Glutamate (MSG) is used in foods as a flavor enhancer while not providing their own separate flavor. The white crystalline powder is derived from glutamic acid, one of the 22 essential amino acids. Glutamic acid is present in seaweed, vegetables, cereal gluten, but MSG is not found naturally by itself. The Federal Drug Administration recognizes MSG to be Generally Recognized As Safe (GRAS). Consuming MSG Is not a health hazard to the individual, but some may exhibit allergic reactions due to hypersensitivity. Symptoms are temporary but may include a burning sensation, facial pressure, headache, nausea or chest pains.

Maltodextrin is a flavorless, easily digested carbohydrate made from cornstarch. A natural, complex carbohydrate, it is not a simple sugar (dextrose, fructose, sucrose etc.) It can be derived from potato or corn starch; used in food industry such as sweets, drink, beer, ice cream, preserved fruit, milk powder, malted mild, cake, biscuit and bread, as well as in medicine, textile, printing and dyeing, paper making, casting and petroleum drilling; generally recognized as safe.



Maltodextrin often contains Monosodium Glutimate (MSG), to which many people have an adverse reaction to.

Sugar produced from cornstarch; comprised of glucose (dextrose), maltose and higher sugars; 70 percent to 80 percent solids

Sugar based sweeteners are those such as that developed from corn starch. The development of the various types of corn syrups, maltodextrins, and high-fructose corn syrup from corn starch sources could be called one of the greatest changes in the sugar and sweetener industry over several centuries. In the late 1800s it was found that corn starch could be hydrolyzed and a sugar formed. It was not until the 1970s that it became commercially a major product bringing about changes in the food industry. Over-reliance in the food industry and over-indulgence by consumers of these processed sugers, particularly high fructose corn syrup, has most likly contributed to obesity in many western countries.



These sweeteners are processed and refined using a series of separation, and grinding processes. Finally, the products are converted and fermented. From this processing a five classes of corn sweeteners are formed. This does not include the corn syrup conversion into high-fructose corn syrup.

Milk from which the cream has been removed



Skim milk contains more calcium than whole milk.



Most of the calcium in milk is not contained in the fat that is removed when 'skimming' the milk. But rather in the water content of the milk. Removing the part of the milk with a lower percentage of calcium, increases the relative percentage of calcium in the remaining milk.

Lactose, a carbohydrate found only in milk, is one of nature's ways of delivering calories to infant mammals. One-sixth as sweet as table sugar, lactose is added to food as a slightly sweet source of carbohydrate. Milk turns sour when bacteria convert lactose to lactic acid. Many people, especially non-Caucasians, have trouble digesting lactose. Bacteria in their guts may produce gas.

Blue cheese is a general classification of cow's milk and/or goat's milk cheeses with a blue or blue-green mold.



Roquefort cheese is a particular blue cheese that is made in the south of France. Some other blue cheeses are Stilton (England), Gorgonzola (Italy), Danablu (Denmark), and Americas' entry, Maytag Blue Cheese. These are just a few, there are many more blue cheeses.



The blue mold in these cheeses is due to mold spores from Penicillium roqueforti or Penicillium glaucum, etc. Originally each of these cheeses were produced in caves in their respective areas, where the mold was naturally present. This combined with the unique nutrients that the mold grew on in the caves affected the flavor, texture and blue-green color of the mold in each of these cheeses. In the beginning, this was most likely discovered by accident when cheeses were stored in the caves, and they developed mold. Then someone decided to taste the cheese that others might have thought to be ruined, and realized how exquisite the taste had become.



Most blue cheeses today are either injected with the mold, as with Roquefort, or the mold is mixed right in with the curds, as it is with Gorgonzola, to insure even distribution of the mold. Most of these cheeses must still be aged in the original caves where they were developed to bear the name.



The process for making America's "Maytag Blue Cheese" was developed by the Iowa State U. in 1941 (it is a process for making blue cheese with pasteurized milk.) Production was begun by Fred Maytag II (of dishwasher fame) when he heard about the new process. Maytag blue is also aged in specially designed caves.



Some specialist cheeses are made using mouldy breadcrumbs rather than chemical moulds, thus they may contain wheat.

There are specific enzymes that break down protein, fat and carbohydrate; these are protease, amylase and lipase respectively.

Cheese is a solid food made from the milk of cows, goats, sheep, and other mammals. Cheese is made by curdling milk using some combination of rennet (or rennet substitutes) and acidification. Bacteria acidify the milk and play a role in defining the texture and flavor of most cheeses. Some cheeses also feature molds, either on the outer rind or throughout.



There are hundreds of types of cheese produced all over the world. Different styles and flavors of cheese are the result of using milk from various mammals or with different butterfat contents, employing particular species of bacteria and molds, and varying the length of aging and other processing treatments. Other factors include animal diet and the addition of flavoring agents such as herbs, spices, or wood smoke. Whether the milk is pasteurized may also affect the flavor. The yellow to red coloring of many cheeses is a result of adding annatto. Cheeses are eaten both on their own and cooked as part of various dishes; most cheeses melt when heated.



For a few cheeses, the milk is curdled by adding acids such as vinegar or lemon juice. Most cheeses, however, are acidified to a lesser degree by bacteria, which turn milk sugars into lactic acid, followed by the addition of rennet to complete the curdling. Rennet is an enzyme mixture traditionally obtained from the stomach lining of young cattle, but now also laboratory produced. Vegetarian alternatives to rennet are available; most are produced by fermentation of the fungus Mucor miehei, but others have been extracted from various species of the Cynara thistle family.

A colorless, crystalline organic compound belonging to the family of carboxylic acids, present in practically all plants and in many animal tissues and fluids. It is one of a series of compounds involved in the physiological oxidation of fats, proteins, and carbohydrates to carbon dioxide and water.



First isolated from lemon juice by a Swedish chemist, Carl Wilhelm Scheele, in 1784, citric acid is manufactured by fermentation of cane sugar or molasses in the presence of a fungus, Aspergillus niger. It is used in confections and soft drinks (as a flavoring agent), in metal-cleaning compositions, and in improving the stability of foods and other organic substances (by suppressing the deleterious action of dissolved metal salts)."



Citrus fruits are notable for their fragrance, and most are juice-laden. They contain a high proportion of citric acid giving them their characteristic astringent odour and flavour. They are also good sources of vitamin C. In botanical terms, "The fruit of all Citrus trees, in which the true fruit is the peel, [is] made up of an outer layer, brightly colored and rich in glands, a spongey whitish mesocarp, and a membraneous endocarp surrounding the segments. The succulent parts we eat is only a secondary tissue developed as a filler"

Flavor(s) Natural & Artificial

A combination of both what is considered “natural” and “artificial” flavoring under the Federal Drug Administration(FDA) Regulations. Artificial flavoring “means any substance, the function of which is to impart flavor, which is not derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, fish, poultry, eggs, dairy products, or fermentation products thereof.” In other words, substances not found in nature to add flavor to a substance is considered artificial. See Artificial Flavor. Natural flavoring “means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional.” See Natural Flavor.

Sodium Caseinate

Sodium Caseinate is a modified protein extracted from milk. It has no odor or taste and is used as a thickening and whitening agent in dairy products. The protein component utilizes emulsification, water absorption, gelling, and stabilization properties. It is used in dairy non-creamers to act as a creamy, white dairy substitute without the lactose that people who are lactose-intolerant cannot digest. Because of its large difference between the “milk derivative” that is sodium caseinate and real cream or milk, it is considered non-dairy. There is controversy whether sodium caseinate still has all the nutritional benefits that milk has because it is non-dairy. It is also a source of free glutamic acid. See monosodium glutamate (MSG).

Produced from the fermentation of corn SUGAR, xanthan gum is used as a thickener, EMULSIFIER and STABILIZER in foods such as dairy products and salad dressings.

Some people are allergic to xanthan gum, with symptoms of intestinal gripes, diarrhea, temporary high blood pressure, and migraine headaches

Also, since xanthan gum is produced by a bacterium that is fed corn to grow, some people allergic to corn will also react to it. Yellow Phrygian Husk is a common source of bacterium in which xanthan gum is created

Also used by people who are allergic to gluten

Dipotassium phosphate - also phosphoric acid, dipotassium salt; dipotassium hydrogen orthophosphate; potassium phosphate, dibasic - is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium.

Yellow 5

Also known as Tartrazine or E102, the Yellow 5 dye is a type of “azo” dye with few chemical similarities to all other food colorings. It is the second-most-widely used coloring substance and is used in the coloring of potato chips, jams, candy, drinks, pet food, etc. It can produce various shades of green according to the manufacture’s wishes as well as many yellow colors. All dyes are considered additives by the FDA through the Federal Food, Drug, and Cosmetic Act (FD&C Act) since it is not used for the purpose of consumption, but to improve the appearance of the product. Yellow 5 is also used in hair dyes and shampoos. Many allergic reactions have been reported due to prolonged use of the dye such as worsened asthma symptoms, skin rashes, and uticaria. Those intolerant of aspirin are highly recommended to avoid this additive. The dye has been banned in Norway, Austria, and Germany, but not all of Europe since it would affect many food businesses economically. Yellow 5 may be contaminated with carcinogens such as benzidine and 4-aminobiphenyl during the manufacturing process. There is no scientific proof of Yellow 5’s links to cancer, but it is “Generally Recognized As Safe”, or GRAS.

Yellow 6

Commonly known as Tartrazine, E110, or Sunset Yellow, Yellow 6 is a food coloring that is added to foods to produce an orange to yellow color. All dyes are considered additives by the FDA through the Federal Food, Drug, and Cosmetic Act (FD&C Act) since it is not used for the purpose of consumption, but to improve the appearance of the product. It is the third-most-widely used dye, but evidence shows that the manufacturing process used to create the dye can also result in the production of a carcinogenic red dye called Sudan 1. Sudan 1 is a dye commonly found in solvents, oils, waxes, petrol, and shoe and floor polishes. If consumed, Sudan 1 can damage cellular DNA, or genetic material, to cause tumors.

Tartrazine (also known as "FD&C Yellow Number 5" or "E-102" in Europe) is a coal-tar derivative that is used to color foods, cosmetics, and other products. It is literally industrial waste.



Tartrazine is also reputed to be a catalyst in hyperactivity/ADD, other behavioral problems, asthma, migranes, thyroid cancer, and lupus.



With many children are being diagnosed as "hyperactive" these days. There is research that shows there could be a link (and that dietary changes can help.) Many of the children on Ritalin or other behavioral drugs may be eating a diet rich in harmful food additives that are approved by the government as safe. Some schools have noticed a major difference in pupils' behavior after banning snacks with tartrazine.

Yellow 5 Lake

Adding “lake” after the name of a dye indicates that the dye is mixed with Aluminum Hydroxide. Aluminum hydroxide is safe as a food ingredient and often sold as an antacid. Mixing the Aluminum Hydroxide with Yellow 5 allows the manufacturer to color the surface of a solid and ensures that it will not run off easily if the product gets wet. See Yellow 5.

FD&C Yellow No.6; used in cereals, bakery, sweets, snack foods, ice cream, drinks and canned fish; synthetic; also in many medications including Berocca, Polaramine, Ventolin syrup; side effects are urticaria (hives), rhinitis (runny nose), nasal congestion, allergies, hyperactivity, kidney tumours, chromosomal damage, abdominal pain, nausea and vomiting, indigestion, distaste for food; seen increased incidence of tumours in animals; banned in Norway

Industry-sponsored animal tests indicated that this dye, the third most widely used, causes tumors of the adrenal gland and kidney. In addition, small amounts of several carcinogens contaminate Yellow 6. However, the FDA reviewed those data and found reasons to conclude that Yellow 6 does not pose a significant cancer risk to humans. Yellow 6 may also cause occasional allergic reactions.

The manufacturer doesn't want the color to run off if the pill gets a little wet. The answer is to use a dye in a lake form.

A lake is a solid, non water soluble form of a dye. It's produced by mixing the dye with Aluminum Hydroxide. By itself Aluminum Hydroxide is a safe food ingredient and it's often sold as an antacid. When combined with Dye, the chemicals form a deep powder that can be applied to the outsides of tablets, gumballs and other solids. You may also notice this form listed in the ingredients as "Aluminum Lake"

Color(s) Added

This term is usually followed by a specific color that the food item contains. It can be naturally derived food coloring or artificial depending on the manufacturer. Natural dyes are extracts that are plant based, while artificial dyes are petroleum based.

The fields of application of pure potato starch and its derivatives are extremely wide and varied. The products are used e.g. as binders, thickeners, stabilisers, fillers etc. in food products, potato starch = potato flour = potato starch flour = katakuriko Notes: This gluten-free gravies. Its main advantage over other starch thickeners is that it's a permitted ingredient for Passover, unlike cornstarch starch is used to thicken soups and and other grain-based foods.



Because potatoes are eaten so frequently they are very significant nutritionally. Potatoes are a good source of vitamin C, potassium and fibre and contain some magnesium. They are high in starch so will stop you feeling hungry for a long time. There is a special fibre in potato skin that helps to protect against some cancers, so to get the most goodness from your potato, leave the skin on. Potatoes contain anti–oxidants which research shows are able to inhibit the development of some cancers. In addition to this, anti–oxidants also decrease your risk of heart disease.



Potatoes are not fattening, however some cooking and preparation methods are! Sometimes potatoes have had a pretty bad reputation for being fattening, but it isn't the potatoes fault it is what we do to it.

Yeast Extract Autolyzed

Also called Yeast Autolysate, autolyzed yeast extract is the result from the water-soluble components of the yeast cell breaking down proteins under acidic and cold environments. It contains free glutamic acid, the source of the flavor enhancing properties of the yeast extract. The product is used as a flavor enhancer and can be found as a liquid, paste, powder, or granular form. See Monosodium Glutamate.

This finely ground flour is made from soybeans and, unlike many flours, is very high in protein (twice that of wheat flour) and low in carbohydrates. Soy flour is ordinarily mixed with other flours rather than being used alone. It has a wide variety of uses such as for baking and to bind sauces. In Japan, it's very popular for making confections. Soy flour is sold in health-food stores--sometimes under the name kinako--and in some supermarkets.



Although soyfoods are widely recognized for their nutritional qualities, interest in soyfoods has risen recently because scientists have discovered that a soy component called isoflavones appears to reduce the risk of cancer. More research needs to be done to determine exactly how isoflavones work, but it appears that as little as one serving of soyfoods a day may be enough to obtain the benefits of this anticancer phytochemical.



Traditional soy products such as tofu, tempeh, and soy milk are very high in protein. Tempeh has the highest percentage of protein of the traditional soy products providing approximately 22 grams of protein for each 4 ounce (113 gram) serving. Tofu provides approximately 9 grams of protein for a similar small serving size. The Recommended Dietary Allowance of protein for adult males (aged 25-50) is appoximately 63 grams and 50 grams for adult females (aged 25-50). Soy products can provide a significant portion of one's daily protein needs.



It is important to keep in mind, however, that the balance of amino acids (protein building blocks) in soy is not the same as meat. Because soy foods does not have an ideal balance of amino acids, some experts recommend taking in a little extra soy foods and/or combining soy products or legumes with a whole grain dish at meals where other protein (e.g., eggs, fish) is not eaten. The amino acids in whole grains combine well with amino acids in soy and legumes to make a more ideal balance of amino acids. If a person's diet is reasonably-balanced, however, there is usually no need to be concerned about getting enough protein.

Vegetarians and health enthusiasts have known for years that foods rich in soy protein offer a good alternative to meat, poultry, and other animal-based products. As consumers have pursued healthier lifestyles in recent years, consumption of soy foods has risen steadily, bolstered by scientific studies showing health benefits from these products. Last October, the Food and Drug Administration gave food manufacturers permission to put labels on products high in soy protein indicating that these foods may help lower heart disease risk.



As with health claims for oat bran and other foods before it, this health claim provides consumers with solid scientific information about the benefits of soy protein and helps them make informed choices to create a "heart healthy" diet. Health claims encourage food manufacturers to make more healthful products. With soy, food manufacturers have responded with a cornucopia of soy-based wares. (See "The Soy Health Claim.")



No sooner had FDA proposed the health claim regulation, however, than concerns arose about certain components in soy products, particularly isoflavones. Resulting questions have engulfed the regulation in controversy.



This came as no surprise to Elizabeth A. Yetley, Ph.D., lead scientist for nutrition at FDA's Center for Food Safety and Applied Nutrition . "Every dietary health claim that has ever been published has had controversy," she says, "even the relationship of saturated fat to a healthy diet."



While the controversy may seem confusing to the consumer giving it casual consideration, a careful review of the science behind the rule reveals a strict divide between what FDA allows as a health claim based on solid scientific research and related issues that go well beyond the approved statements about health benefits of soy protein.

Basic Egg Facts



Air Cell

The empty space between the white and shell at the large end of the egg.



When an egg is first laid, it is warm. As it cools, the contents contract and the inner shell membrane separates from the outer shell membrane to form the air cell.



The candler uses the size of the air cell as one basis for determining grade. In Grade AA eggs, the air cell may not exceed 1/8-inch in depth and is about the size of a dime. The air cell of Grade A eggs may exceed 3/16-inch in depth. For Grade B eggs, there is no limit on air cell size.



As the egg ages, moisture and carbon dioxide leave through the pores of the shell, air enters to replace them and the air cell becomes larger.



Although the air cell usually forms in the large end of the egg, it occasionally moves freely toward the uppermost point of the egg as the egg is rotated. It is then called a free or floating air cell. If the main air cell ruptures, resulting in one or more small separate air bubbles floating beneath the main air cell, it is known as a bubbly air cell.



You can see the air cell in the flattened end of a peeled, hard-cooked egg.

Albumen

Also known as egg white. Albumen accounts for most of an egg's liquid weight, about 67%. It contains more than half the egg's total protein, niacin, riboflavin, chlorine, magnesium, potassium, sodium and sulfur. The albumen consists of 4 alternating layers of thick and thin consistencies. From the yolk outward, they are designated as the inner thick or chalaziferous white, the inner thin white, the outer thick white and the outer thin white. Egg white tends to thin out as an egg ages because its protein changes in character. That's why fresh eggs sit up tall and firm in the pan while older ones tend to spread out.



Albumen is more opalescent than truly white. The cloudy appearance comes from carbon dioxide. As the egg ages, carbon dioxide escapes, so the albumen of older eggs is more transparent than that of fresher eggs.



When egg albumen is beaten vigorously, it foams and increases in volume 6 to 8 times. Egg foams are essential for making souffles, meringues, puffy omelets, and angel food and sponge cakes.



The yolk or yellow portion makes up about 33% of the liquid weight of the egg. It contains all of the fat in the egg and a little less than half of the protein.



With the exception of riboflavin and niacin, the yolk contains a higher proportion of the egg's vitamins than the white. All of the egg's vitamins A, D and E are in the yolk. Egg yolks are one of the few foods naturally containing vitamin D.



The yolk also contains more phosphorus, manganese, iron, iodine, copper, and calcium than the white, and it contains all of the zinc. The yolk of a Large egg contains about 59 calories.



Double-yolked eggs are often produced by young hens whose egg production cycles are not yet completely synchronized. They're often produced, too, by hens who are old enough to produce Extra Large eggs. Genetics is a factor, also. Occasionally a hen will produce double-yolked eggs throughout her egg-laying career. It is rare, but not unusual, for a young hen to produce an egg with no yolk at all.
