Do buy sprouts that look clean and rinse them well at home. Keep them refrigerated. The only way to ensure safety is to cook them thoroughly, but that destroys the most appealing qualities of salad sprouts. If you add large bean sprouts to a stir-fry, let them simmer for a few minutes. People with weakened immune systems, as well as the very old and the very young, should not take a chance on raw sprouts.
Colostrum is secreted by all lactating mammals shortly after giving birth, before milk is produced.
It contains many substances that are vital for the growth, immune system, and overall health of newborns. So what's good for newborn calves is not good for newborn humans, let alone adults. Many companies are aggressively marketing supplements of bovine colostrum, claiming that the capsules, powders, and liquids can treat cancer, diabetes, arthritis, and other diseases, as well as build muscle, burn fat, boost athletic performance, improve mood, and slow aging. Some brands contain vitamins, herbs, and other compounds. There are even bovine colostrum supplements for pets.
