Proteins


Happy Monday! It is hard to believe that the month of January has already flew by. As Forever Fitness is expanding our education to our members about nutrition, one of the most recent topics that we have been talking about are macronutrients. Last week’s blog dug deeper into the examination of carbohydrates and addressing the negative stigma behind them. To continue the topic of macronutrients this week’s blog will discuss our beloved protein as gym goers.


What is Protein?

Protein is made of amino acids that are used to help grow and maintain skeletal muscles, tendons, blood vessels, hair, skin, and nails. There are 20 different amino acids that are needed by your body. There are 10 amino acids that are made by your body while others are received from our diet.

Non-Essential amino acids (made by your body) - alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.1


Essential amino acids (provided from our diet) - arginine (required for the young, but not for adults), histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.1


Unlike carbohydrates, excess protein that is consumed cannot be stored in body. Failure to obtain as little as one of the ten essential amino acids can lead to breakdown of muscles.


What Foods Contain Protein?

How much do we need?

According to the Academy of Nutrition and Dietetics, here is a chart that displays how much protein you should be consuming based off your age and sex. You may note that males need slightly a bit more protein than females. This is due to the large amount of muscle mass that is natural present in the male body.


Daily Protein Recommendation

2-3 years Female and male: 2-ounce equivalents

4-8 years Female and male: 4-ounce equivalents

9-13 years Female and male: 5-ounce equivalents

14-18 years Female: 5-ounce equivalents

14-18 years Male: 6½ ounce equivalents

19-30 years Female: 5½ ounce equivalents

31-50 years Female: 5-ounce equivalents

31-50 years Male: 6-ounce equivalents

“These recommendations for protein are provided in one-ounce equivalents. One-ounce equivalents of protein foods include . . .”2

  • One ounce of cooked meat, poultry, or fish

  • ¼ cup cooked beans

  • 1 egg

  • 1 tablespoon peanut butter

  • ½ ounce nuts or seeds

Other information about protein:

When too much protein is consumed, excesses is stored as fat and excess amino acids are excreted. Outside of proteins immediate function, consumption of this nutrient also helps fight infection, carry fats, vitamins, minerals, and oxygen around the body, build and contract muscles, keep body fluids in balance and clot blood.
