Many people didn’t know that overeating red meat increases your risk of colon cancer and possibly other cancers, such as pancreatic and prostate cancer. The American Institute for Cancer Research recommends eating no more than 18 ounces of cooked red meat a week, that’s not a lot more than the size of a big steak some people order when out at a steakhouse restaurant. In case you were wondering, though, red meat is any meat from a mammal.

It may come as a shocker to some that pork is also a red meat, even though it has been marketed as “white meat.” Other red meat includes lamb, veal, mutton, and beef. Of course, the less red meat you eat, the better. A serving size of red meat is 3 ounces, or about the size of a deck of cards for comparison. Eating it only on occasion is best, to guarantee that you aren’t eating much of it, as part of a plant-based diet.
