Semolina - The coarsely ground endosperm of durum wheat. High in protein, it is used by American and Italian manufactures to make high quality pasta products such as macaroni and spaghetti. It is also used for couscous in Africa and Latin America.



semolina Substitutes: durum wheat flour (also good for pastas, inferior color) OR kamut flour (This makes a decent pasta and can be tolerated by most people with wheat allergies) OR spelt flour (Like kamut flour, this makes a good pasta and is tolerated by most people with wheat allergies.) OR all-purpose flour (Pasta made entirely of this is less firm than that made with semolina. To keep it from getting mushy, cook the pasta in plenty of water and eat it immediately after it's cooked.)

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.

or 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.

Broccoli means ‘little sprouts’ in Italian. It’s part of the Brassica family of vegetables which also includes cauliflower, cabbages, Brussels sprouts, turnips and many of the Asian greens. The stalks, buds and most of the leaves of broccoli are edible.

Broccoli is very good for you. It’s got lots of vitamin C and vitamin K and is a very good source of calcium, iron and potassium. Broccoli contains compounds which research strongly indicates inhibit the development of some cancers.

Corn or maize is native to America but is now grown throughout the world. In grain form it is the staple diet for American Indians in Mexico, Peru and Southern North America.



The Maori were given maize by American sailors which they grew and ate both fresh and fermented. The fermented corn was known as kaanga. Its strong smell didn't appeal to Pakeha who ate corn mainly as a grain. Eventually a sweet form was developed, and hence the name sweetcorn, it wasn't until the 1960's that sweetcorn became a really popular fresh vegetable. Several varieties are available including some with white kernels and others with a mix of yellow and white kernels. Varieties differ in sweetness. Recently the supersweet varieties have become popular, with Honey 'n' Pearl being the most widely grown.



Sweetcorn is a very good source of fiber, protein and starch. corn is a great source of vitamin A, fiber, and other nutrients.

Nutritional Benefits

Carrot is one of the most healing foods that provides the finest and highest quality in nutrients, especially from its juice. It is an excellent source of pro-vitamin A, vitamins C, D, E, K, B1 and B6.

It is rich with biotin, potassium, calcium, magnesium, phosphorus, organic sodium and some trace minerals.



The known phytonutrients in carrots are lutein, lycopene, anti-oxidants alpha, beta and gamma carotenes, zeaxanthin and xanthophyll. You don't need to remember these fancy names, but just remember that phytonutrients are nature's marvelous provision for healing of various diseases.



Health Benefits



Carotenes, the famous ingredient in carrots, is an anti-oxidant that has powerful healing virtues for many diseases. Drinking a glass of carrot juice daily will do much more for you than many bottles of supplement tablets. Here are some disorders that can be helped by drinking carrot juice regularly:



Acidosis:

The vital organic alkaline elements in carrots help balance the blood acidity and blood sugar.



Acne:

Its powerful cleansing properties are effective in detoxifying the liver, thus overall effective for acne which are caused by toxicity of the blood.



Anemia:

Carrot's molecules are closest to human's hemoglobin molecules, making it very beneficial in blood-building.



Atherosclerosis:

The highly cleansing power of this miracle juice scrubs away even the old build-up of arterial deposits, reducing the risks of heart diseases and stroke.



Asthma:

The anti-oxidants effectively protects the respiratory system from infections and free-radical attacks.



Cancer:

Studies show that adding one carrot per day in our diet significantly reduces cancer risks.



Cholesterol:

Pectin in carrots lowers the serum cholesterol levels.



Congestion:

Carrot juice is very effective in dispelling mucus from the ear, nose and throat area, easing nasal congestion, sinusitis, phlegm and mucus in the throat and other similar disorders.



Constipation:

Take five parts of carrot juice with one part of spinach juice regularly to regulate chronic constipation problems.



Emphysema:

If you smoke or are exposed to second-hand smoke, taking carrot juice regularly may well save your life.



Eyes:

Beta-carotene, lutein and zeaxanthin are some of the finest nourishment that help keep the optic system in tip-top condition, with special protection against astigmatism, macular degeneration and cataracts.



Fertility:

One of the reasons for infertility is lack of nutrients and enzymes in your dietary. Carrot juice taken regularly, is able to nourish your body back to fertility.



Inflammations:

Its anti-inflammatory effect greatly helps reduce arthritis, rheumatism, gout and other inflammations.



Immune systems:

It does wonders for boosting the immune system by increasing the production and performance of white blood cells; building resistant to various kinds of infections.



Nursing mothers:

Carrot juice helps enhance the quality and quantity of a mother's breast milk.



Pregnancy:

Drinking carrot juice regularly during pregnancy, especially during the last few months, will reduce the chances of jaundice in baby. No, you won't get an orange baby!



Skin problems:

The high quality vitamin C and other rich nutrients in carrot juice efficiently nourish the skin, preventing dry skin, psoriasis and other skin blemishes.



Thread worms:

One small cup of carrot juice in the morning taken daily for a week can help clear up thread worms in children.



Ulcers:

The abundance of nutrient present in carrots help nourish cells that have been starved of nutrients which result in ulcers.



Water retention:

Carrot juice is diuretic and helps to eliminate excess fluids from the body, reducing water retention, especially for women during their monthly menstruation cycle and in pregnant women.

Consumption Tips

Carrots that are no longer than 6 inches tend to be sweeter. So choose the shorter variety if you like it sweet or the longer one if you prefer it less sweet.

The most nutrients are concentrated just under the skin so try not to peel off the skin. To clean it, simply use a hard brush to brush the skin.

Cut them lengthwise to preserve the nutrients as when cut in small rounds, they easily lose their nutrients in water when you wash or cook them.



Caution

You may have heard of people "turning orange" from drinking carrot juice. It is not the carrot juice that is showing through the skin but is an overflow of materials which have been clogging the liver and are being eliminated with the consumption of carrot juice. This shows how effective carrot juice is at cleansing?a good sign that the system is getting a good clean-up. When this "turning orange" happens, continue to take your carrot juice and the color will eventually go off as it cleanses.

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.

Upon standing, unhomogenized milk naturally separates into two layers-a MILK FAT-rich cream on top and almost fat-free (or skimmed) milk on the bottom. Commercially, the cream is separated from the milk by centrifugal force. Almost all cream that reaches the market today has been pasteurized. There are many varieties of cream, all categorized according to the amount of milk fat in the mixture. Light cream, also called coffee or table cream, can contain anywhere from 18 to 30 percent fat, but commonly contains 20 percent. Light whipping cream, the form most commonly available, contains 30 to 36 percent milk fat and sometimes stabilizers and emulsifiers. Heavy cream, also called heavy whipping cream, is whipping cream with a milk fat content of between 36 and 40 percent.

Simply put, this is dehydrated skimmed milk



Skimmed milk is 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.

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.

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.

Pungent or aromatic seasonings obtained from thebark, buds, fruit, roots, seeds or stems of various plants and trees (whereasHERBS usually come from theleafy part of a plant). Spices were prized long before recorded history. Thoughthey've always been used to flavor food and drink, throughout the eons spiceshave also been favored for a plethora of other uses including crowning emperors,making medicines and perfumes, religious ceremonies and as burial accoutrementsfor the wealthy. Over 3,000 years ago the Arabs monopolized the spice trade,bringing their rare cargo back from India and the Orient by arduous camelcaravans.

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.

Any of a class of sweet,Soluble Carbohydrate,as sucrose,glucose,sucrose from sugar cane and sugar beets.

We get our energy from the nutrients in food. The main sources of energy are carbohydrates (starches and sugars), fats and proteins. The body can be compared to an engine that converts the energy in food into the energy we need to live. Sugars and starches are forms of carbohydrate. Nutritionists recommend that about half of our energy should be supplied by carbohydrates. The majority of this should be from starchy foods like cereals, rice, potatoes, pasta or bread, with the remainder coming from sugars. During digestion (the process by which we break down food substances ready for absorption and use by the body) complex starchy foods are broken down into sugars.

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).

Soy lecithin is a mixture of fatty substances that are derived from the processing of soybeans. Lecithin is separated from soybean oil by the addition of water and centrifugation (rapid spinning) and purified for use as a food additive. Its chemical name is phosphatidylcholine, which identifies its major components of choline, phosphoric acid, glycerin, and fatty acids. Lecithin is used widely in foods as an emulsifier, stabilizer, and antioxidant.



Studies show most soy-allergic individual can safely eat products containing soy lecithin without experiencing any allergic reactions.



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.

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.

Heavy cream, also called heavy whipping cream, is whipping cream with a milk fat content of between 36 and 40 percent.

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.

Cream (including light whipping cream) is a dairy product that is composed of the higher-butterfat layer skimmed from the top of milk before homogenization. In un-homogenized milk, over time, the lighter fat rises to the top. In the industrial production of cream this process is accelerated by using centrifuges called "separators". In many countries, cream is sold in several grades depending on the total butterfat content. Cream can be dried to a powder for shipment to distant markets.



Cream produced by cows (particularly Jersey cattle) grazing on natural pasture often contains some natural carotenoid pigments derived from the plants they eat; this gives the cream a slight yellow tone, hence the name of the yellowish-white colour, cream. Cream from cows fed indoors, on grain or grain-based pellets, is white.



Enzymes are biomolecules that catalyze (i.e., increase the rates of) chemical reactions.[1][2] Nearly all known enzymes are proteins. However, certain RNA molecules can be effective biocatalysts too. These RNA molecules have come to be known as ribozymes.[3] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.



Like all catalysts, enzymes work by lowering the activation energy (Ea or ?G‡) for a reaction, thus dramatically increasing the rate of the reaction. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts by being much more specific. Enzymes are known to catalyze about 4,000 biochemical reactions.[4] A few RNA molecules called ribozymes catalyze reactions, with an important example being some parts of the ribosome.[5][6] Synthetic molecules called artificial enzymes also display enzyme-like catalysis.[7]



Enzyme activity can be affected by other molecules. Inhibitors are molecules that decrease enzyme activity; activators are molecules that increase activity. Many drugs and poisons are enzyme inhibitors. Activity is also affected by temperature, chemical environment (e.g., pH), and the concentration of substrate. Some enzymes are used commercially, for example, in the synthesis of antibiotics. In addition, some household products use enzymes to speed up biochemical reactions (e.g., enzymes in biological washing powders break down protein or fat stains on clothes; enzymes in meat tenderizers break down proteins, making the meat easier to chew).



Genetically modified (GM) foods are foods derived from genetically modified organisms. The DNA of genetically modified organisms has been modified through genetic engineering, unlike similar food organisms developed through the conventional genetic modification of selective breeding (plant breeding and animal breeding) or mutation breeding. GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil, but animal products have been developed. For example, in 2006 a pig engineered to produce omega-3 fatty acids through the expression of a roundworm gene was controversially[1][2] produced.[3] Researchers have also developed a genetically-modified breed of pigs that are able to absorb plant phosphorus more efficiently, and as a consequence the phosphorus content of their manure is reduced by as much as 60%. [4]



Critics have objected to GM foods on several grounds, including perceived safety issues,[5] ecological concerns, and economic concerns raised by the fact that these organisms are subject to intellectual property law.
