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.

Whey protein is a mixture of globular proteins isolated from whey, the liquid material created as a by-product of cheese production. Some preclinical studies in rodents have suggested that whey protein may influence glutathione production and possess anti-inflammatory or anti-cancer properties; however, human data are lacking. The effects of whey protein on human health are of great interest and this protein mixture is being investigated as a way of reducing disease risk, or as a supplementary treatment for several diseases. Whey protein is commonly marketed and ingested as a dietary supplement, and various health claims have been attributed to it in the alternative medicine community. Although whey proteins are responsible for some milk allergies, the major allergens in milk are the caseins.

Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain. The amino acids in a polymer chain are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code.[1] In general, the genetic code specifies 20 standard amino acids, however in certain organisms the genetic code can include selenocysteine — and in certain archaea — pyrrolysine. Shortly after or even during synthesis, the residues in a protein are often chemically modified by post-translational modification, which alter the physical and chemical properties, folding, stability, activity, and ultimately, the function of the proteins. Proteins can also work together to achieve a particular function, and they often associate to form stable complexes.[2]



Like other biological macromolecules such as polysaccharides and nucleic acids, proteins are essential parts of organisms and participate in virtually every process within cells. Many proteins are enzymes that catalyze biochemical reactions and are vital to metabolism. Proteins also have structural or mechanical functions, such as actin and myosin in muscle and the proteins in the cytoskeleton, which form a system of scaffolding that maintains cell shape. Other proteins are important in cell signaling, immune responses, cell adhesion, and the cell cycle. Proteins are also necessary in animals' diets, since animals cannot synthesize all the amino acids they need and must obtain essential amino acids from food. Through the process of digestion, animals break down ingested protein into free amino acids that are then used in metabolism.



Proteins were first described and named by the Swedish chemist Jöns Jakob Berzelius in 1838. However, the central role of proteins in living organisms was not fully appreciated until 1926, when James B. Sumner showed that the enzyme urease was a protein.[3] The first protein to be sequenced was insulin, by Frederick Sanger, who won the Nobel Prize for this achievement in 1958. The first protein structures to be solved were hemoglobin and myoglobin, by Max Perutz and Sir John Cowdery Kendrew, respectively, in 1958.[4][5] The three-dimensional structures of both proteins were first determined by x-ray diffraction analysis; Perutz and Kendrew shared the 1962 Nobel Prize in Chemistry for these discoveries. Proteins may be purified from other cellular components using a variety of techniques such as ultracentrifugation, precipitation, electrophoresis, and chromatography; the advent of genetic engineering has made possible a number of methods to facilitate purification. Methods commonly used to study protein structure and function include immunohistochemistry, site-directed mutagenesis, and mass spectrometry.

Flavor(s) Artificial

"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.

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.

Acesulfame Potassium

Also seen as Acesulfame K, Ace-K, Sunett, or Sweet One, Acesulfame Potassium is a sugar substitute that is 200 times sweeter than table sugar. It is used as a flavor enhancer and sweetener for foods. It is a low calorie food ingredient because our bodies do not metabolize it. Acesulfame K also is not consumed by bacteria so it does not contribute to tooth decay as sugar does. However, methylene chloride is used for the production of Acesulfame K, which also is used as a propellant, degreaser, and paint stripper. There are many side effects with consumption of Acesulfame K, including increased risk for cancer, triggering chronic respiratory disease, or abnormal cravings for sweets. The chemical remains stable when exposed to heat, basic, or acidic conditions. Since it is stable under high heat, manufacturers use Acesulfame K potassium to use in baking and extending shelf life. This artificial sweetener has a slight bitter aftertaste, but companies are using this with sodium ferulate to mask the bitterness. Other companies use Acesulfame K with other alternative sweeteners such as Aspartame or sucralose to control the use of it. The Food and Drug Administration (FDA) recommends the acceptable daily intake of 15mg/kg of body weight/day.

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.

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

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.
