Some consumers want to know where food comes from because they do not wish to consume hormones added to beef by the production-practice of implanting cattle with a tiny amount of estrogen. Estrogen, used in this manner, acts as a repartitioning agent causing the animal to grow more bone and muscle, and to deposit less fat, making the beef leaner. Some additional estrogen is found is a 3-ounce steak from an implanted animal; it contains 1.9 nanograms of estrogen while a 3-ounce steak from a non-implanted animal contains 1.3 nanograms of estrogen. It should be pointed out, however that the daily endogenous production of estrogen by a non-pregnant woman is 480,000 nanograms per day and by a normal adult man is 136,000 nanograms per day. So, if a non-pregnant woman eats one 3-ounce steak from an implanted animal she will have 480,001.9 nanograms of estrogen in her body that day – a normal adult man who eats such a steak will have 136,001.9 nanograms of estrogen in his body that day. Or, they could eat 3-ounces per day of ice-cream, cabbage, wheat germ or soybean oil and raise their body levels of estrogen by 520, 2,016, 3,400 or 1,700,000 per day.
