Eating processed meat can cause cancer, especially in the colon, and scientists have enough proof to say this — even if they're still figuring out exactly how it happens.

A lab-made version of a human immune peptide can kill germs at very low doses and is safer for skin cells than many current preservatives, so it might be a good natural option for keeping cosmetics...

Eating meat affects iron levels more in women who still have periods than in men or women who don’t — probably because those women need more iron and lose it monthly.

If you're a premenopausal woman, especially an endurance athlete, eating more meat might help keep your iron levels up and reduce your chances of being low on iron.
