Protein is one of the essential building blocks of good nutrition. It helps build muscle and maintain strength. It also helps your blood clot, fights infection and transports vital nutrients throughout your body. And it helps you feel full after a meal.
It's a simple truth: You need adequate protein every day to help your body function at its best. What's not so simple is knowing how much you need and what types are healthiest for you. Let's break down the basics.
How much protein do you need?
In general, you should consume 0.8 gram of protein per kilogram each day. If you weigh 150 pounds, for example, that's 68 kilograms, which adds up to a little more than 54 grams of protein per day.
That may seem like a lot. But consider the amount of protein in these common foods:
• 1 cup of black beans: 15 grams.
• 1/2 cup of lentils: 8 grams.
• 2 tablespoons of peanut butter: 8 grams.
• 1 cup of quinoa: 8 grams.
• 4 ounces of tofu: 12 grams.
• 4 ounces of tempeh: 20 grams.
You'll likely find that these individual servings of protein add up quickly throughout the day.
You may need more or less protein each day than recommended above, depending on your age, health and other factors.
Discuss your individual protein intake requirements with your doctor.
Make healthy protein choices
Many Americans get more protein than they need, but their protein sources often lack variety. Some protein choices are obvious: red meat, poultry, sausage, lunch meat and whole milk. However, these foods are often high in saturated fat or are highly processed. That's why it's important to choose more low-fat, unprocessed and plant-based proteins.
• Heart-smart protein choices include:
• Fatty fish, such as salmon, mackerel, sardines and bluefin tuna.
• Beans, peas and lentils.
• Walnuts, almonds and other nuts.
• Pumpkin seeds and chia seeds.
• Low-fat milk, yogurt and cottage cheese.
• Lean, unprocessed meat and poultry.
Protein bars and shakes can also contribute to your daily protein intake. But be sure to read the labels on these products before you buy them—some contain high amounts of sugar and additives. Whey protein powder, which is made from milk, is high in protein and doesn't have as many additives.
More is not always better
Getting enough protein is essential. But be careful not to consume too much. It could be detrimental to your health, especially if you have kidney stones, kidney disease or lupus.
