Protein is essential to good health. The very origin of the word — from the Greek protos, meaning "first" — reflects protein’s top-shelf status in human nutrition. You need it to put meat on your bones and to make hair, blood, connective tissue, antibodies, enzymes, and more. It’s common for athletes and bodybuilders to wolf down extra protein to bulk up. But the message the rest of us often get is that our daily protein intake is too high.
The Recommended Dietary Allowance (RDA) for protein is a modest 0.8 grams of protein per kilogram of body weight. The RDA is the amount of a nutrient you need to meet your basic nutritional requirements. In a sense, it’s the minimum amount you need to keep from getting sick — not the specific amount you are supposed to eat every day.
To determine your daily protein intake, you can multiply your weight in pounds by 0.36, or use this online protein calculator. For a 50-year-old woman who weighs 60 kg and who is sedentary (doesn’t exercise), that translates into 53 grams of protein a day.
Protein: Is more better?
For a relatively active adult, a daily protein intake to meet the RDA would supply as little as 10% of his or her total daily calories. In comparison, the average American consumes around 16% of his or her daily calories in the form of protein, from both plant and animal sources. But is that too much?
For some people, there may be potential benefits of higher daily protein intake to preserve muscle mass and strength. How and when you consume protein might also influence its effectiveness.
What should you do?
Research on how much protein is the optimal amount to eat for good health is ongoing and is far from settled. The value of high-protein diets for weight loss or cardiovascular health, for example, remains controversial.
Before you start ramping up your daily protein intake, there are a few important things to consider. For one, don’t read "get more protein" as "eat more meat." Beef, poultry, and pork (as well as milk, cheese, and eggs) can certainly provide high-quality protein, but so can many plant foods — including whole grains, beans, and other legumes, nuts, and vegetables. The table below provides some healthier sources of protein.
It’s also important to consider the protein "package" — the fats, carbohydrates, vitamins, minerals, and other nutrients that invariably come along with protein. Aim for protein sources low in saturated fat and processed carbohydrates and rich in many nutrients.
One more thing: If you increase protein, dietary arithmetic demands that you eat less of other things to keep your daily calorie intake steady. The switches you make can affect your nutrition, for better or for worse. For example, eating more protein instead of low-quality refined carbohydrates, like white bread and sweets, is a healthy choice — though how healthy the choice also depends on the total protein package.
