Bovine spongiform encephalopathy (BSE), also called "mad cow disease" is a fatal neurological disease in cows though to be caused by consuming contaminated animal feed. Some countries have included in the feed given to cattle, ground up animal parts including brains and nervous systems of animals killed for food. Some of these animals had early stages BSE, and the infectious agent was passed on to the animals who consumed the feed. There is now evidence that some people who ate the meat from animals infected with BSE became infected themselves. Nearly 100 people have now died from what are now called "transmissible spongiform encephalopathies" (TSEs) believed to have been caused by eating BSE-contaminated beef.
Glandular materials start out as healthy (or unhealthy) as the animals from which they are made. For this reason, all reputable processors of glandular concentrates will use only USDA-inspected animals as the original source. The highest quality glandular materials will be made from animals grown in a healthier environment. New Zealand beef cattle make the best source of bovine glandular concentrates, because they are free-range rather than lot-raised, and fed pasture grasses and hay rather than cattle feed. Additionally, New Zealand is one of the only countries in the world considered completely free of BSE (mad cow disease) and other transmissible spongiform encephalopathies (TSEs).
Porcine means derived from pig.
In order to be absorbed, minerals, whether from foods or in supplements, have to be combined with a "carrier" molecule. When this molecule is a fragment of protein (an amino acid), and the mineral-amino acid compound forms a stable molecule, it is referred to as an amino acid chelate. Because the body is very efficient at absorbing amino acids, chelated minerals are more easily transported across the intestinal wall than are non-chelated minerals.
The glycemic index (GI) is a ranking of foods on a scale from 0 to 100 according to the extent to which they raise blood sugar levels after eating. Glucose is given a relative number of 100 to provide a baseline to which all others can be compared. For example, an apple has a glycemic index of 38 which is less than half that of glucose, but higher than soybeans (which have a glycemic index of 18). Other common foods and their corresponding glycemic indices are Corn Flakes (84), dark rye bread (80), and bananas (54).
