It's a good question-and one that concerns anyone who cooks with rice. It's true that there's a risk of food poisoning from leftover rice, but the problem lies more in how the rice is cooled and stored rather than in the cooking. Raw rice contains traces of a bacterium known as Bacillus cereus.
OPSS Answer. Insulin-like growth factor type 1âcommonly known as IGF-1âis a hormone produced naturally in the liver and involved in the human bodyâs growth and development. It is present in colostrum, the milk produced by mammals (including humans and cows) the first few days after giving birth.
IGF-I is the âmiddle-manâ in the growth process. Growth hormone stimulates the liver and other body tissues to produce IGF-I, which then acts as the link between growth hormone in the blood and the machinery inside cells that causes growth. The amount of IGF-I in the blood provides an indirect measure of the amount of growth hormone present.
