It's common to be concerned with whether or not you’re eating enough protein for good health. The truth of the matter is we don’t need as much as you might think and it’s very easy to get your daily protein, even if you’re a vegetarian. One thing is for certain, protein deficiency is not a problem in the healthy American population.

Dietary proteins are involved in building and maintaining body tissues and other special metabolic functions. As an energy source, proteins are equivalent to carbohydrates in providing the same calories per gram. Proteins play a major role not only in the structure of our body tissues, but also in the formation of enzymes and the function of the immune system. They also aid in the transportation of certain vitamins and minerals as well as cholesterol and triglycerides.

For example, the protein in eggs has a higher digestibility than that in soy flour. Not to worry though, protein is in many foods that we eat on a regular basis, so as long as you choose a balanced eating plan to supply you with the nutrients you need, you don’t have to worry. 

Foods that provide the most protein

Eggs

Meats: chicken, fish, beef, pork, seafood 

Meat alternatives: soy beans, nuts, legumes, textured soy protein, tofu, eggs 

Dairy: milk, cottage cheese, yogurt, cheese

Grains, some vegetables and fruits provide little protein in comparison to the other groups, but it all adds up in the end.

How much protein do I need?

The Recommended Dietary Allowances (RDA) suggest 10-35% of our calories come from protein. Based on a 2,000 calories diet, 50 grams of protein a day would represent the low end of that recommendation. For the healthy adult, another way to calculate your needs is to multiply your body weight (in kilograms) by 0.8 grams. To covert your body weight from pounds to kilograms simply divide your weight by 2.2.

Weight (in kilograms) x 0.8 grams = protein requirements per day

Examples of protein content in foods

3-ounce piece of chicken has 21 grams

1 cup of milk (skim, low fat or whole) has 8 grams

1 egg has 7 grams

1 4-ounce cup of Greek yogurt has 10 grams

½ cup beans has 6 grams

If you just ate the 5 items listed above, you’d already reach your minimum protein goal and that doesn’t include all the other items that are lower in protein, but still contribute to your goal.

Examples of protein content in meals

Breakfast: 1 egg, toast & fruit -- 10 grams

Snack: 1 banana -- 1 gram

Lunch: 2 ounce turkey & cheese wrap -- 25 grams

Snack: 1 oz mixed nuts -- 5 grams

Dinner: 3 oz salmon, baked potato and salad -- 21 grams

Total: 62 grams of protein

 

So the bottom line is eat a variety of foods, three meals a day and don’t worry about counting those protein grams.
