红肉含的铁多一般来说是好事情：

3. Are there nutritional benefits from eating red meat?

A: Red meat is high in iron, something many teenage girls and women in their childbearing years are lacking. The heme iron in red meat is easily absorbed by the body. Red meat also supplies vitamin B12, which helps make DNA and keeps nerve and red blood cells healthy, and zinc, which keeps the immune system working properly.

Red meat provides protein, which helps build bones and muscles.

“Calorie for calorie, beef is one of the most nutrient-rich foods,” says Shalene McNeil, PhD, executive director of nutrition research for the National Cattlemen’s Beef Association. “One 3-ounce serving of lean beef contributes only 180 calories, but you get 10 essential nutrients.”
