Canada’s Beef Cattle Research Council (BCRC) has collected some interesting stats on the estrogen level in beef.

A 75-gram serving of beef from cattle treated with hormone implants contains two nanograms (ng~one billionth of a gram) of estrogen.

“A person would need to eat 3,000,000 hamburgers made with beef from implanted cattle to get as much estrogen as the average adult woman produces every day, or 50,000 hamburgers to get as much estrogen as the average adult man produces every day” says BCRC’s science director, Dr. Reynold Bergen.

Considering there are about 45,000 ng of estrogen in 75 grams of white bread, the bun probably has far more estrogen than the beef!
