Eating the Right Amount
There is no hard and fast way to measure your required protein intake - but rather, there are a few: by percentage of calories, by weight and by age. This may be confusing, but the end numbers for all measures are not so much conflicting as they are inclusionary.
The Recommended Daily Allowance (RDA) change with age:
Try Them All: Protein Sources
Consider this: a 6-oz. porterhouse steak will provide 38 grams of protein - and 44 grams of fat, 16 of them saturated (three-quarters of the recommended daily intake). An equal portion of salmon will provide 34 grams of protein and 18 grams of fat, 4 of them saturated. A cup of cooked lentils will give you 18 grams of protein and only 1 gram of fat. When choosing how you'll get your daily recommended dose of protein, try to incorporate as many plant-based sources first, then animal sources - and red meat last.
Lean cuts of beef and extra lean ground beef are good sources of complete proteins, but are also high in saturated fat. Limit your consumption of red meat and make it an only-sometimes option. Boneless and skinless chicken breasts and turkey cutlets are the leanest poultry choices. Meat portions should be about the size of a deck of cards. One chicken breast provides about 23 grams of protein.
