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.

All varieties of tea come from the leaves of a single plant, which contains some of the most powerful antioxidants known. The difference between green and black tea is simply one of fermentation. To protect itself, the body makes and uses antioxidants to scavenge and neutralize free radicals believed to contribute to aging and diseases including cancer.



Tea contains antioxidant polyphenols called catechins. Green tea contains the highest levels of catechins, followed by oolong and black teas. Other studies have shown catechins halt tumor cells and protect healthy cells from damage

Corn Syrup High Fructose

Corn syrup is glucose produced from corn starch in a process called wet milling. Wet milling isolates the components of the corn through chemical or biochemical separation. The sugars are further separated by the use of enzymes. Since fructose is sweeter but not naturally found in corn, scientists have ways to convert the glucose into fructose. High fructose corn syrup (HFCS), also known as corn sugar, is a combination of glucose and fructose. Depending on the level of sweetness, the glucose to fructose ratio is adjusted. For example HFCS 55 is 55% fructose and is usually used in soft drinks. HFCS 42 is 42% fructose and used in foods that require only a little sweetening. The chemical composition of high fructose corn syrup is similar to that of sucrose, or table sugar. Still, the Food and Drug Administration (FDA) declared that under the formal definition of “natural,” HFCS does not meet the requirements. The enzymes that are used to separate the sugars are synthetic, deeming HFCS unnatural. Also, there has been controversial evidence showing that the consumption of HFCS is associated with obesity.

This bright yellow citrus fruit is oval in shape, with a pronounced bulge on the blossom end. The flesh is juicy and acidic. The lemon can range in size from that of a large egg to that of a small grapefruit. Some have thin skins while others have very thick rinds, which are used to make candied lemon peel.



Though the lemon is an excellent source of vitamin C (one provides 40 to 70 percent of the minimum daily requirement), it begins to lose its vitamin power soon after it's squeezed. There's a 20 percent loss of vitamin C after only 8 hours at room temperature or 24 hours in the refrigerator..

Mangoes are a good source of Vitamin A, and have large amounts of Vitamins B and C. Mangoes have more carotenoids than most fruits, which helps to ward-off colds and reduces the risk of cancer and heart disease. Mangoes are also high in fiber, and contain a small amount of carbohydrates. You'll also find calcium, iron, potassium and a some protein in mangoes.

Pears are an excellent source of water-soluble types of fibres, such as pectin.



Pears contain both soluble and insoluble fibre, which is helpful in lowering cholesterol and acts as a 'fuel' to encourage the growth of healthy bacteria in the bowel.



Pears contain no fat or cholesterol and are an excellent source of dietary fibre and vitamin C. The average pear contains four grams of fibre, which is equivalent to one and a half cups of brown rice.



The dietary fibre in pears has for some time been thought to assist in the fight against serious illnesses including some forms of cancer.

One of the most important and abundant of the carotenes, a portion of which the liver converts to vitamin A. It should be noted, however, that while excess vitamin A can be toxic to the body, residual beta carotene is quickly eliminated. Scientists now believe that beta carotene is a powerful ANTIOXIDANT with properties that can contribute to reducing cancer and heart disease. It's found in vegetables like carrots, broccoli, squash, spinach and sweet potatoes. Beta carotene's orange-yellow pigment is also used as a coloring in foods like butter and margarine.Carotenoids are the red, orange and yellow plant pigments that give fruits and vegetables their vivid colors. All fruits and vegetables contain varying concentrations of carotenoids, but their colors are often covered up by green chlorophyll contained in the plant.



There are more than 600 different naturally-occuring carotenoids. Some of them have been identified as playing a vital role by protecting our cells and tissues from the damaging effects of free radicals and singlet oxygen. Lycopene, the carotenoid that gives tomatoes their red color, is particularly effective at quenching the destructive free radical singlet oxygen.

Caffeine

The addition of caffeine into a product is to appeal to the consumer as a stimulant. Stimulants help keep people awake and alert. However, overconsumption of caffeinated products can cause jitteriness and affect calcium metabolism. Many theories of why caffeine is an addicting stimulant point to the “drug’s” interference with the hormone adenosine, which tells the body that it needs to sleep. Without catching up on the sleep deprived by caffeine, the human body will not function at its best in performing physically and mentally. Interestingly enough the ingredient guarana is caffeine. It is a woody vine native to Brazil and is commonly seen in energy drinks, protein bars, and weight-loss products. If caffeine and guarana are listed under the food label, it means the caffeine has two sources. Caffeine is still a stimulant and has the same effects no matter what source it came from naturally or artificially.



Reid, T.R. “Slurped in black coffee or sipped in green tea, gulped down in a soda or knocked back in a headache pill, caffeine is the world's most popular psychoactive drug.” National Geographic. Web. 17 May 2011. .





An alkaloid that exists naturally in tea, kola nut and coffee; clearly toxic in high doses, can cause heart palpitations, high blood pressure, vomiting, convulsions, headache, diarrhea, frequent urination, dehydration, insomnia, stomach cramps, hand tremors, muscle twitches; acts as laxative, also saps the body's supply of calcium; used as a mild stimulant in moderation.



Caffeine is the only drug that is present naturally or added to widely consumed foods (quinine is the other drug used in foods). It is mildly addictive, one possible reason that makers of soft drinks add it to their products. Many coffee drinkers experience withdrawal symptoms, such as headaches, irritability, sleepiness, and lethargy, when they stop drinking coffee. Because caffeine increases the risk of miscarriages (and possibly birth defects) and inhibits fetal growth, it should be avoided by women who are pregnant or considering becoming pregnant. It also may make it harder to get pregnant. Caffeine also keeps many people from sleeping, causes jitteriness, and affects calcium metabolism. The caffeine in a cup or two of coffee is harmless to most people. But if you drink more than a couple of cups of coffee or cans of caffeine-containing soda per day, experience symptoms noted above, are at risk of osteoporosis, or are pregnant, you should rethink your habit.

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"

Some brands of Citric Acid may be made from wheat, however this is very rare.

Guarana (pronounced gwa-ra-naa) is a berry that grows in Venezuela and the northern parts of Brazil. The name 'Guarana' comes from the Guarani tribe that lives in Brazil.

The taste of Guarana is distinctive and unique, and the main reason for its success in Brazil as a soft drink. The main ingredient of guarana is guaranine, which is chemically identical to caffeine. This is the reason for the energy boost people get after taking guarana.

The success in Brazil was reason enough for the Pepsi and Coca Cola to start the production of their own guarana soda varieties. Pepsi tried to market 'Josta' in the US (and failed); Coca Cola still sells 'Kuat' in Brazil (with some success). In most cases, imitation brands still can't compete with the original Brazilian brands



Extract

The distilled or evaporated oils of foods or plants (such as nuts, seeds, fruits, vegetables, herbs, spices, bark, buds, roots, leaves, meat, poultry, seafood, fish, dairy foods, or eggs) that are dissolved in an alcohol base or allowed to dry to be used as a flavoring. Food extracts as they are often labeled, are used to add a concentrated flavor to many food dishes, especially baked goods and desserts, without adding additional volume. Available in solid (cubes, granules or powdered), liquid or jelled form, extracts may be labeled as pure, natural or artificial. Pure and natural extracts are governed by laws in many countries that require compliance with procedures that take the extract ingredients directly from the named flavor, such as extracting oils directly from the vanilla bean to make pure or natural vanilla extract. Artificial extracts are flavors that do not necessarily use any ingredients directly from a source named for the extract but instead used combinations of ingredients to arrive at a flavor representative of the named food extract, such as artificial lemon extract. Some of the most widely used extracts include vanilla, almond, anise, maple, peppermint, and numerous solid or jelled extracts such as beef and chicken bouillon or meat demi-glaces. As an example of how the pure and natural extract is made, vanilla extract is created by soaking vanilla beans in water and an alcohol-based solution where it ages for several months, during which time the vanilla flavor is extracted from the bean. Anise extract, a sweet licorice tasting flavoring, is produced by dissolving the oil of anise seeds into alcohol.



Grape extract is produced to assist with the wine making process. Compounds from the skin of grapes are extracted and added to the wine in order to impart tannin, color, and body into a wine. The characteristics of the wine can be changed dramatically by the amount of time the wine is in contact with the skins. If the grapes are in contact for too long, the resulting wine may be too potent, or what is sometimes called “over-extracted”.



Juices of fruits and vegetables are often extracted as juice extracts to be used similar to other food extracts, as a flavoring when preparing foods. A common utensil for the purpose of extracting lemon juice is available to assist with home recipes requiring a lemon flavoring.

"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.

Monofloral honey is a type of honey which has a high value in the marketplace because it has a distinctive flavor or other attribute due to its being predominantly from the nectar of one plant species. [1]



While there may never be an absolute monofloral type, some honeys are relatively pure due to the prodigious nectar production of a particular species, such as citrus (Orange blossom honey), or there may be little else in bloom at the time.



Beekeepers learn the predominant nectar sources of their region, and often plan harvests to keep especially fine ones separate. For example, in the southern Appalachians, sourwood honey, from a small tree that blooms late in the season, is highly regarded. Beekeepers try to remove the previously produced dark and strong flavored tulip poplar honey, just before the sourwood bloom, so the lighter sourwood is not contaminated. During sourwood bloom, there is little else for the bees to forage.



Monofloral honeys are also kept in separate tanks and labeled separately so as to command a premium price.

Panax Ginseng has been used by the Chinese for more than 5,000 years. Panax is derived from the Latin word panacea meaning "cure all". Although there are other types of ginseng, the Panax form offers the highest level and range of ginsenosides. Its many attributes include increased mental and physical endurance, helping the body handle stress more effectively, a reduction in cholesterol, increased energy, relief in some of the discomforts of menopause and enhanced sexual desire. Though benefits may vary, this unique herb will continue to be a leader in the expanding use of botanicals for personal healing.



Extract

The distilled or evaporated oils of foods or plants (such as nuts, seeds, fruits, vegetables, herbs, spices, bark, buds, roots, leaves, meat, poultry, seafood, fish, dairy foods, or eggs) that are dissolved in an alcohol base or allowed to dry to be used as a flavoring. Food extracts as they are often labeled, are used to add a concentrated flavor to many food dishes, especially baked goods and desserts, without adding additional volume.

Ginseng is the most famous Chinese herb. It is the most widely recognized plant used in traditional medicine. Various forms of ginseng have been used in medicine for more than 7000 years. Several species grow around the world, and though some are preferred for specific benefits, all are considered to have similar properties as an effective general rejuvenator.

The name panax is derived from the Greek word panacea meaning, "all healing" and the benefits of ginseng are recognized as such. Ginseng is commonly used as an adaptogen, meaning it normalizes physical functioning depending on what the individual needs (for example, it will lower high blood pressure, but raise low blood pressure).



It is also used to reduce the effects of stress, improve performance, boost energy levels, enhance memory, and stimulate the immune system. Oriental medicine has deemed ginseng a necessary element in all their best prescriptions, and regards it as prevention and a cure. It is said to remove both mental and bodily fatigue, cure pulmonary complaints, dissolve tumors and reduce the effects of age.



Ginseng is native to China, Russia, North Korea, Japan, and some areas of North America. It was first cultivated in the United States in the late 1800's. It is difficult to grow and takes 4-6 years to become mature enough to harvest. The roots are called Jin-chen, meaning 'like a man,' in reference to their resemblance to the shape of the human body.



Native North Americans considered it one of their most sacred herbs and add it to many herbal formulas to make them more potent. The roots can live for over 100 years.



Ginseng contains vitamins A, B-6 and the mineral Zinc, which aids in the production of thymic hormones, necessary for the functioning of the defense system. The main active ingredients of ginseng are the more than 25 saponin triterpenoid glycosides called "ginsenosides". These steroid-like ingredients provide the adaptogenic properties that enable ginseng to balance and counter the effects of stress. The glycosides appear to act on the adrenal glands, helping to prevent adrenal hypertrophy and excess corticosteroid production in response to physical, chemical or biological stress.



Studies done in China showed that ginsenosides also increase protein synthesis and activity of neurotransmitters in the brain. Ginseng is used to restore memory, and enhance concentration and cognitive abilities, which may be impaired by improper blood supply to the brain.



Ginseng helps to maintain excellent body functions. Siberian ginseng has been shown to increase energy, stamina, and help the body resist viral infections and environmental toxins. Research has shown specific effects that support the central nervous system, liver function, lung function and circulatory system.



Animal studies have shown that ginseng extracts stimulate the production of interferons, increase natural killer cell activity, lower cholesterol and decrease triglyceride levels. Men have used the herb to improve sexual function and remedy impotence. Ginseng is believed to increase estrogen levels in women and is used to treat menopausal symptoms.



It is also used for diabetes, radiation and chemotherapy protection, colds, chest problems, to aid in sleep, and to stimulate the appetite.



Part used: Whole root. Powdered in capsules, as an ingredient in many herbal formulas, and as a tea.



Common Use: Ginseng is one of the most popular healing herbs used today throughout the world. It increases mental and physical efficiency and resistance to stress and disease. Ginseng's adaptogenic qualities help balance the body, depending on the individual's needs. It is known to normalize blood pressure, increase blood circulation and aid in the prevention of heart disease.

The scientific name for vitamin C, ascorbic acid helps maintain the red color of cured meat and prevents the formation of nitrosamines, which promote cancer (see SODIUM NITRITE). It helps prevent loss of color and flavor by reacting with unwanted oxygen. It is used as a nutrient additive in drinks and breakfast cereals. Sodium ascorbate is a more soluble form of ascorbic acid. ERYTHORBIC ACID is very similar to ascorbic acid, but has no value as a vitamin. Large amounts of ascorbic acid may reduce the severity of colds and offer other health benefits.

Schisandra (Magnolia Vine) is a genus of shrub commonly grown in gardens. It is a hardy deciduous climber which thrives in virtually any soil; its preferred position is on a sheltered shady wall. It may be propagated by taking cuttings of half-matured shoots in August. Species include S. chinensis, S. glaucescens, S. rubriflora and S. rubrifolia.



It is native to East Asia, and its dried fruit is used medicinally. The berries of S. chinensis are given the name wu wei zi in Chinese (???; pinyin: wu wèi zi), which translates as "five flavor fruit" because they possess all five basic flavors in Chinese herbal medicine: salty, sweet, sour, pungent (spicy), and bitter. In traditional Chinese medicine it is used as a remedy for many ailments: to resist infections, increase skin health, and combat insomnia, coughing, and thirst.



Over 19 species of the genus are said to be used in Chinese medicine, mostly as sedatives and tonic agents. Schisandra may also aid in the treatment of Irritable Bowel Syndrome (IBS) when combined with wormwood, ginger, buplerum, and Codonopsis pilosula. However, there is insufficient evidence to support this claim at this time.



Modern Chinese research suggests that schisandra and other lignans have a protective effect on the liver and an immunomodulating effect. Two human trials in China (one double-blind and the other preliminary) have shown that schisandra may help people with chronic viral hepatitis reports Liu KT from Studies on fructus Schizandre cinensis. Schisandra lignans appear to protect the liver by activating the enzymes that produce glutathione.



Recently, the extract of S. rubriflora, a native of the Yunnan province, was found to contain complex and highly oxygenated nortriterpenoids. The discoverers named those molecules Rubriflorins A-C. [1]

An extract is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol or water. Extracts may be sold as tinctures or in powder form.



The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, and wintergreen.

Vitamin A is very important for maintaining good vision. In fact, the first sign of a vitamin A deficiency is often night blindness. Vitamin A also contributes to the maintenance of healthy skin and mucous membranes that line the nose, sinuses, and mouth. Research has shown that this nutrient is necessary for proper immune system function, growth, bone formation, reproduction, and wound healing. Animal studies also suggest that it provides some protection from toxic chemicals such as dioxins. (Dioxins are released into the air from combustion processes such as commercial waste incineration and burning fuels like wood, coal or oil. These chemicals can also be found in cigarette smoke.)Vitamin A is a fat-soluble vitamin. This means you dont need it every day because any of the vitamin your body doesnt need immediately is stored for future use.

If youre pregnant, you should avoid eating liver because it contains a lot of vitamin A.

Vitamin E, a fat-soluble vitamin, protects vitamin A and essential fatty acids from oxidation (antioxidant)in the body cells and prevents breakdown of body tissues.



Found natural in Vegetable oil, Spinach, whole grains and sunflower seeds.



Deficiency Symptoms: Rare symptoms may include anemia & edema



Toxicity Symptoms: Generally non-toxic; nausea, dizziness & diarrhea can occur

The term “vitamin E” refers to a family of eight related, lipid-soluble, antioxidant compounds widely distributed in plants. The tocopherol and tocotrienol subfamilies are each composed of alpha, beta, gamma, and delta vitamers having unique biological effects. Different ratios of these compounds are found in anatomically different parts of a plant. For example, the green parts of a plant contain mostly alpha-tocopherol and the seed germ and bran contain mostly tocotrienols. Along with other nutrients tocopherols and tocotrienols are concentrated in the bran layers of the rye grain, and are only present at low levels in the flour endosperm. Tocopherols are also present in algae, mint teas, and other food stuff.87-93



When this family of compounds was first discovered and determined to be essential for health, a standardized test for its activity was devised for which the members of the family were rated for their biological activity. In one test, alpha tocopherol scored highest and was rated 100% with all others having lower ratings. In accordance with this rating, alpha-tocopherol was deemed to be the essential compound and was called vitamin E. One International Unit (IU) of vitamin E activity is the activity under this rating of one mg of the plant-derived form of alpha-tocopherol.94



Since the original rating method was established, many additional important biological effects of these compounds have been discovered and many nutritional scientists now consider that rating method to be incomplete. For example, by the original rating, gamma-tocopherol was only 10% to 30% as strong as alpha-tocopherol, yet more recent studies have shown it to be essential for maintaining the health of cell membranes, especially if alpha-tocopherol is being supplemented. New studies continue to elucidate the unique benefits of individual members of the vitamin E family. For these and other reasons, the original definition of vitamin E has been enhanced to include all eight family members and the related compounds that convert to them in the body.94



Vitamin E compounds are usually produced and made available in esterified form as alpha-tocopheryl acetate or alpha-tocopheryl succinate. Neither of these forms has any antioxidant activity until converted to alpha-tocopherol in the body, but they are much more stable with respect to storage time and temperature than the unesterified forms. Moreover, while the acetate form is rapidly activated within the body, activation of the succinate form is slower. The succinate form appears to access and benefit areas of the tissues that are unavailable to the other forms. For this reason, there is a tendency to regard alpha-tocopherol succinate as a distinctly different and beneficial compound. Alpha-tocopherol succinate appears to have longer half-life in the body, and does not interfere with vitamin A or K absorption.95-98



Serious vitamin takers prefer cold-water dispersible dry powder vitamin E supplements in the form of alpha-tocopheryl succinate or acetate because the cold-water dispersible forms are efficiently absorbed even when taken on an empty stomach or with a low-fat meal. The non-cold water dispersible (oil) forms of vitamin E may be poorly absorbed unless taken with several grams of fats or oils.



Cold-water dispersible vitamin E is more efficiently absorbed than some other forms. Both “acetate” and “succinate” vitamin E can come from natural sources. The importance to the consumer is how well the vitamin E absorbs into the bloodstream. Cold-water dispersible vitamin E, whether in a succinate or acetate form, always comes in a white dry powder, while non-cold water dispersible natural and synthetic acetate forms of vitamin E are always in a thick brown oil.
