Animal protein and vegetable protein probably effect our health in the same way. But before each bite consider how it is packaged. A piece of salmon has 34 grams of protein and 18 grams of fat of which only 4 are saturated and about 1500 mg of omega 3's. A porterhouse steak has 36 grams of protein and 44 grams of fat and 16 grams are saturated. Cooked lentils have 18 grams of protein, less than one gram of fat, and alot of fiber.
How much protein do you need each day?
About 8 grams of protein for every 20 pounds of body weight.
White meat, and fish are healtiest animal proteins. Red meat-not so much. Eat it in moderation, as a treat. Studies show people who eat the most red meat and processed meats have the highest risk of premature death from cancer and heart disease.
Beans and legumes and even nuts add excellent proteins and are complete proteins when eaten with grains.
So when you choose your proteins consider the packaging. Is it packaged with saturated fats or fibers, omega 3's or saturated fats?
