Do the growth promotants leave any hormones in the beef?
There is very little difference in the amounts of estrogen found in beef from cattle raised with or without growth promoting hormones. The amount of estrogen in each is miniscule – 1.9 versus 1.3 nanograms per serving. The human body naturally produces far more estrogen than is found in commonly eaten foods, including beef. For instance, an adult woman produces about 253,000 times more estrogen every day than is found in a 3-ounce serving of beef. The FDA regularly tests for, and has never found, residues in meat that would indicate misuse of growth promoting products.
