Water is the most abundant nutrient in our body and plays an important transmission function in every body cell and tissue. Sixty percent of our body weight is water. The fact that you can live without food for a long period of time, even months, but live only for a few days without water is true. Under normal conditions, the body releases about one quart of water daily. Therefore, replacement to equal the losses is very important for survival.

Dehydration is the most common problem of water imbalance due to water losses and deprivation. The effects of dehydration on nutrition can adversely affect ones health. Dehydration is the major cause of ones diminished ability to perform during endurance activities. Body water is lost through the stomach, respiration, sweat, and the kidneys. It is recomended that 24oz of water a day should be taken. This amount can double or even triple with endurance type exercise.



A note about water: More and more evidence shows the benifit of being well hydrated.

Studies show that 75% of Americans are chronically dehydrated (likely applies to half the world's population), leading to possible health problems such as fatigue. In 37% of Americans, the thirst mechanism is so weak that it is often mistaken for hunger, leading to over-eating. Even MILD dehydration will slow down one's metabolism as much as 3%.



Bottled Water: Some types of bottled water are not subject to the same regulations as tap water. These are regulated as food products, and their regulations are largely related to sanitary food handling and processing practices. Bottled water manufacturers will provide a detailed report on the quality of their product to consumers who call to request it.

Sorbitol

Sorbitol is a type of sugar alcohol that is also found naturally in fruits. It is a white crystalline powder that is typically used as an artificial sweetener like in sugar-free chewing gum. It is considered a nutritive sweetner because it has 4 calories/gram like table sugar. Sorbitol is also used in toothpaste, tobacco, toiletries, and cosmetics. It is a stable substance and can withstand high temperatures so baked goods do not burn easily. In addition, sorbitol has many other functions such as a dispensing substances in textiles, whitening teeth, prevent staleness in candy, or maintain adhesiveness of a product. Diabetics can ingest sorbitol because of its slow digestion time. Many complaints have surrounded sorbitol because of excess consumption. Too much sorbitol (as little as 10 grams per day) can lead to irritable bowel syndrome with symptoms including flatulence and bloating. Sorbitol is a natural laxative since consumption of excess fruits leads to the general effects. It is not well absorbed, so excess water enters the gastrointestinal tract, leading to diarrhea or flatulence. Sorbitol is safe to consume but the amounts consumed should be wary.

Sulfites (also sulphites) are compounds that contain the sulfite ion SO2-3 (additive IUPAC name: trioxidosulfate(2-)). The sulfite ion is the conjugate base of sulfurous acid. Although the acid itself is elusive, its salts are widely used.





Sulfites occur naturally in all wines to some extent.[1] Sulfites are commonly introduced to arrest fermentation at a desired time, and may also be added to wine as preservatives to prevent spoilage and oxidation at several stages of the winemaking.



In the United States, wines bottled after mid-1987 must have a label stating that they contain sulfites if they contain more than 10 parts per million.[2]



In the European Union an equivalent regulation came into force in November 2005.[3] Organic wines are not necessarily sulfite-free.[2]





[edit] Other food

Sulfites are often used as preservatives in dried fruits, and dried potato products.



Most beers no longer contain sulfites. Although shrimp is sometimes treated with sulfites on fishing vessels, the chemical may not appear on the label. In 1986, the Food and Drug Administration in the United States banned the addition of sulfites to all fresh fruit and vegetables that are eaten raw.

"The term natural flavor or 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."

The new labeling law effective in 2006, The Food Allergen Labeling and Consumer Protection Act (FALCPA), requires manufacturers to declare if one or more of the 8 major food allergens are contained in a natural flavoring. The top 8 major food allergens are defined as: milk, egg, fish, crustacean shellfish, tree nuts, wheat, peanuts and soybeans.

If you are managing food allergies other than the top 8 major food allergens, however, the new law will not be of assistance to you in identifying the sources in any natural flavoring stated on a label.

The FDA does not require companies to disclose ingredients of color or flavor additives so long as all the chemicals in them are considered by the agency to be GRAS ("generally recognized as safe") enabling companies to maintain secrecy of formulas. It also hides the fact that flavors often contain more ingredients than the foods to which they give taste.

A typical artificial strawberry flavor contains over 30 chemicals. According to manufacturer safety data sheets those chemicals cause eye irritation, corneal damage, eye burns, skin irritation, severe / permanent damage to digestive tract, gastrointestinal irritation, gastrointestinal tract burns, CNS depression, neurological effects, liver abnormalities, cardiac abnormalities, or other harm.

Natural flavor, according to the FDA, must be derived entirely from natural sources (herbs, spices, fruits, vegetables, beef, chicken, yeast, bark, roots, etc). Consumers prefer to see natural flavors on a label out of a belief they are more healthful.

Natural flavor is not necessarily more healthful or purer than an artificial flavor. Almond flavor when derived from natural sources may contain traces of hydrogen cyanide, a deadly poison. When derived by mixing oil of clove & amyl acetate, it does not. Natural flavors and artificial flavors are often manufactured at same chemical plants.

Flavor manufacturing may also involve biotechnology, using enzyme reactions, fermentation, & fungal and tissue cultures. Flavors created by these methods are considered natural flavors by the FDA.

In addition to flavor chemicals also think about genetic engineering of food, DNA or gene alteration, and medicines and hormones given to cows, cattle, hogs, and chickens. What affect does it have upon us? Some are suspected causes of cancer or other problems.

When a natural flavor or artificial flavor is added to a food or drink the resultant processed food is no longer natural & is potentially harmful.

Cellulose may be used in foods as a hydrocolloid. As a vegetable gum, it serves a major role as a stabilizer. Cellulose is also frequently used as a fat replacer or substitute. In foods, the cellulose ingredients are insoluble fibrous particles that are capable of holding water and suspending the dispersed particulates. It can replace fat because it gives an appropriate mouth feel and lends a glossy opaque appearance when used.

Cellulose is an excellent source of insoluble fiber. Unlike soluble fiber, insoluble fiber does not feed bacteria well and is not readily fermented into short chain fatty acids.

Approved in the United States in April 1998, sucralose (a synthetic chemical) can be used in soft drinks, baked goods, ice cream, sweetener packets, and other products. It previously had been used in Canada, Europe, and elsewhere. Sucralose is safer than saccharin and cyclamate and doesn’t raise the concerns that tests on acesulfame-K and aspartame have raised.

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.

Sodium Benzoate

Used as a food preservative or antiseptic, sodium benzoate is a white crystalline powder chemically known as C7H5O2Na or E211. Although it is classified by the Federal Drug Administration as safe, sodium benzoate is a controversial additive. Sodium benzoate was previously used for centuries as a preservative to prevent the growth of microbial organisms in the food. In presence of Vitamin C (ascorbic acid) such as in jams, sodium benzoate can form the chemical benzene. Benzene is known to damage DNA, genetic material, which can lead to leukemia and other cancers. Since sodium benzoate works best in acidic environments, the consumption of sodium benzoate is a rising issue.

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"

One of the most widely used colors is caramel, the color of burnt sugar.



There are many different types of caramel color, each engineered to serve a particular purpose in food chemistry. They are all based on the cooking of sugars and starches. Sometimes acids such as acetic acid, citric acid, lactic acid, or phosphoric acid, are used to break the bonds between sugars to create invert sugars, or to make sugars from starches, before the sugars are raised to a higher temperature for carmelization.



The heat is carefully controlled during carmelization to get the right products from the reaction. Besides acids, alkalies and salts may be used to further control the process.



Caramel color is a colloid, a mixture in which solid particles are suspended in water. The particles in colloids have electric charges that keep the particles from clumping together and settling out of solution. The charges can be positive or negative. If a negative coloid is added to a product that has positive colloidal particles in it, the two will attract one another and clump up, making the product cloudy.



Caramel color can be made with either positively or negatively charged particles. This allows manufacturers to use negative colloidal caramel in acidic soft drinks, and positive in beers and soy sauces. Beer has positively charged proteins suspended in it, and soy sauce has a high salt content that requires the more salt-tolerant positive caramel color.



Caramel color is an emulsifying agent as well as a colorant. In soft drinks, it helps keep the flavor oils suspended in the solution.



In chocolate milk, the muddy color of caramel is darkened by the addition of FD&C Red #40 to give what the industry refers to as a "Dutch" chocolate shade. Blues and yellows are sometimes used to give a more brown color.



Caramel color is added to baked goods, to poultry, to milk to give an "eggnog" color, to malt vinegars, canned meats, syrups, and soups, stews, and gravies.



If caramel color is made in North America it is likely to be gluten-free.



The problem with caramel color is that it may or may not contain gluten depending on how it is manufactured. In the USA caramel color must conform with the FDA standard of identity from 21CFR CH.1. This statute says: "the color additive caramel is the dark-brown liquid or solid material resulting from the carefully controlled heat treatment of the following food-grade carbohydrates: Dextrose (corn sugar), invert sugar, lactose (milk sugar), malt syrup (usually from barley malt), molasses (from cane), starch hydrolysates and fractions thereof (can include wheat), sucrose (cane or beet)." Also, acids, alkalis and salts are listed as additives which may be employed to assist the caramelization process.

Lactic acid (chemically, alpha or 2-Hydroxypropionic acid) takes roles in metabolic processes in the body; in red blood and in skeletal muscle tissues as a product of glucose and glycogen metabolism. Lactic acid is an "alpha hydroxy acid: which has a hydroxyl group on the carbon atom next to the acid group. If the hydroxy group is on the second carbon next to the acid group, it is called beta-hydroxy acid. Lactic acid is converted in vivo to pyruvic acid (an alpha keto acid) which occurs as an intermediate product in carbohydrate and protein metabolism in the body. Lactic acid occurs as two optical isomers since the central carbon atom is bound to four different groups; a dextro and a levo form ( or an inactive racemic mixture of the two); only the levo form takes part in animal metabolism. Lactic acid is present in sour milk and dairy products such as cheese, yogurt, and koumiss, leban, wines. Lactic acid causes tooth decay since lactic acid bacteria operates in the mouth. Although it can be prepared by chemical synthesis, production of lactic acid by fermentation of glucose and other sugar substances in the presence of alkaline such as lime or calcium carbonate is a less expensive method. The six-carbon glucose molecule is broken down to two molecules of the three-carbon compounds (lactic acid), during this anaerobic condition. Synthetic lactic acid is used commercially in tanning leather and dyeing wool; as a flavouring agent and preservative in food processing and carbonated beverages; and as a raw material in making plastics, solvents, inks, and lacquers; as a catalyst in numerous chemical processes. Lactic Acid is available as aqueous solutions of various concentrations, usually 22 - 85 percent (pure lactic acid is a colourless, crystalline substance.)



Zinc is an essential mineral having a role in the maintenance of the body's nervous and immune systems (T-cell function). This mineral is involved in the biochemical reactions as an antioxidant in the healing process and develops normal tissues Zinc is a cofactor in enzymatic reactions such as protein synthesis polymerases and in carbonic acid anhydrase. Zinc maintains the body's alkaline balance. Zinc finger, a structural domain found in many gene-regulatory proteins, is a component of hydrophobic hormones acting stabilizing the biomembrane structures and cell membrane metabolism. Zinc deficiencies may result in prolonged wound healing, delayed sexual maturation, mental lethargy, skin changes, and susceptibility to infections. Gluconate and citrate forms are mainly used as zinc supplements. They are easily absorbed by the body.

Vitamin B3



Also called Niacin, Nicotinic Acid, Niacinimide, 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.

PANTOTHENIC ACID (vitamin B5) plays a still-undefined role in the metabolism of proteins, carbohydrates, and fats. Pantothenic acid is an integral part of coenzyme A and plays the important role of decarboxylating pyruvate in the citric acid cycle. Clinically, pantothenic acid is necessary for the synthesis of red blood cells, steroid metabolism, neuron activity, and stimulation of antibody production.



Common sources of pantothenic acid are cheese, corn, eggs, liver, meats, peanuts, peas soybeans, brewer's yeast, and wheat germ.



Because of its wide occurance, pantothenic acid deficiency is very rare unless specifically engineered for the purposes of biochemical investigations.



Along with other B vitamins, pantothenic acid is required for converting food to energy, building red blood cells, making bile, and synthesizing fats, adrenal gland steroids, antibodies, acetylcholine and other neurotransmitters. Pantothenic acid in dexpanthenol lotions and creams relieves the pain of burns, cuts, and abrasions, reduces skin inflammations, and speeds wound healing.

Pantothenic Acid: Also called vitamin B5, is involved in the Krebs cycle of energy production and is needed to make the neurotransmitter acetylcholine. It is also essential in producing, transporting, and releasing energy from fats. Synthesis of cholesterol (needed to manufacture vitamin D and steroid hormones) depends on pantothenic acid. Pantothenic acid also activates the adrenal glands.1 Pantethinea byproduct of pantothenic acidhas been reported to lower blood levels of cholesterol and triglycerides.



Where is it found? Liver, yeast, and salmon have high concentrations of pantothenic acid, but most other foods, including vegetables, dairy, eggs, grains, and meat, also provide some pantothenic acid.

Vitamin B6, also called pyridoxine, is one of eight water-soluble B vitamins. The B vitamins help the body to convert carbohydrates into glucose (sugar), which is "burned" to produce energy. These vitamins, often referred to as the B complex, are also essential in the metabolism of fats and protein. B complex vitamins also play an important role in maintaining muscle tone in the gastrointestinal tract and promoting the health of the nervous system, skin, hair, eyes, mouth, and liver.



Vitamins B12, B6, and B9 (folic acid) work closely together to control blood levels of the amino acid homocysteine. Elevated levels of this substance appear to be linked to heart disease. Plus, vitamin B6 is essential for normal brain development and function, participating in the process of making important brain chemicals called neurotransmitters.



Pyridoxine is an especially important vitamin for maintaining healthy nerve and muscle cells and it aids in the production of DNA and RNA, the body's genetic material. It is necessary for proper absorption of vitamin B12 and for the production of red blood cells and cells of the immune system. Pyridoxine has also been called the "woman's vitamin" because it may help relieve symptoms of premenstrual syndrome (PMS).

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

Vitamin B12, also called cobalamin, is important to good health. It helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA, the genetic material in all cells . Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Once released, B12 combines with a substance called intrinsic factor (IF) before it is absorbed into the bloodstream.

Good sources include meat, particularly liver, salmon, cod, milk, cheese, eggs, yeast extract, and some fortified breakfast cereals.

Vitamin B12 (Cobalamin) is a water soluble vitamin, although small amounts are stored in the liver. It is a member of the B group of vitamins and is vital for the formation of red blood cells, for nerve cells, and the recycling of certain important enzymes.



NOTE: Drinking alcohol may increase your requirement for B12.

EU Recommended Daily Allowance (RDA) is 1 mcg.

Upper Safe Level (USL) for long term use is 3000 mcg.
