Margarine, shortening, non-dairy whiteners, beverages, breakfast cereals, supplements. Beta-carotene is used as an artificial coloring and a nutrient supplement.

The body converts it to Vitamin A, which is part of the light-detection mechanism of the eye and which helps maintain the normal condition of mucous membranes.

Large amounts of beta-carotene in the form of dietary supplements increased the risk of lung cancer in smokers and did not reduce the risk in non-smokers.

Smokers should certainly not take beta-carotene supplements, but the small amounts used as food additives are safe. BRAZZEIN Natural high-potency sweetener Brazzein has not yet been approved as a food additive, but some food manufacturers see it as a better-tasting alternative to stevia-derived rebiana.

Brazzein is a small 54 amino acids protein molecule that occurs naturally in the berries of a climbing vine found in West Africa, where it has been consumed by people and animals. It is about 1, times sweeter than sugar, but, as far as we can determine, it has not been tested for safety.

Because it is a protein, it might cause food allergies. One company is planning to market the sweetener under the name Cweet.

BVO keeps flavor oils in suspension, giving a cloudy appearance to citrus-flavored soft drinks such as Mountain Dew and Fanta Orange.

Decades later, BVO is still poorly tested and remains on the interim list.

Health concerns start with the finding that eating BVO leaves residues in body fat and the fat in brain, liver, and other organs. Indeed, doctors have identified bromine toxicity in two people who drank extremely large amounts of such sodas.

Sensitive, modern studies are urgently needed to better understand the risk, especially at the lower levels typically consumed by large numbers of children. Meanwhile, BVO should not be used it is not permitted in Europe. Cereals, chewing gum, potato chips, vegetable oil.

BHA retards rancidity in fats, oils, and oil-containing foods. While some studies indicate it is safe, other studies demonstrate that it causes cancer in rats, mice, and hamsters.

Those cancers are controversial because they occur in the forestomach, an organ that humans do not have. However, a chemical that causes cancer in at least one organ in three different species indicates that it might be carcinogenic in humans.

That is why the U. This synthetic chemical can be replaced by safer chemicals e. Cereals, chewing gum, potato chips, oils, etc. BHT retards rancidity in oils. It either increased or decreased the risk of cancer in various animal studies.

Residues of BHT occur in human fat. Avoid it when possible. Naturally occurring in coffee, tea, cocoa, coffee-flavored yogurt and frozen desserts. Additive in soft drinks, energy drinks, chewing gum, and waters. Caffeine is one of only two drugs that are 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.
