Are You Sure You're Getting Enough Protein?

Are You Sure You're Getting Enough Protein?
By Frederik 2 years ago 1113 Views

The abundance of protein here in the West is something that many of us take for granted. So how can you be sure that you’re getting enough protein yourself? Read on.


The Basics: Getting Protein from Food

Protein is composed of twenty amino acids. Nine of these amino acids are "essential" because they can’t be made in the body and must be obtained from food. Protein is found in meat, poultry, fish, eggs, dairy products, beans, legumes, nuts, and grains.

A vegetarian diet that contains eggs and dairy products can easily provide adequate protein. For vegans, grains can be combined with beans to provide a better balance of amino acids than either food alone.


How Much Protein Do You Really Need?

As a general rule, approximately 10% to 35% of your calories should come from protein. This translates to 46 grams of protein for the average woman and 56 grams for the average man. Active people will need more and children less. Pregnant women may require as much as 71 grams daily.

Athletes, body builders, and those who do heavy physical labor have a greater need for protein than others. Since muscle is made of protein, individuals who work out require extra protein to build lean tissue. Protein is also the major component of hair, skin, and nails, which makes it a natural beauty food.

Many women who cut calories in an effort to be thin may wind up with less than adequate amounts of protein in their diets. In these cases, the body uses lean tissue as an energy source. When weight is regained, it’s usually in the form of fat. Symptoms of protein deficiency include muscle weakness, fatigue, depression, insomnia, skin conditions, headaches and other problems.


How to Increase Your Protein Intake

Vegans or those who don't have much time to prepare nutritious food can benefit from protein shakes made with juice or milk (dairy, soy, almond or other) and a generous scoop of protein powder. While whey protein from milk is a popular option, dairy-free proteins derived from peas, brown rice, soy or other foods are widely available.


The Benefits of Whey Protein

Whey protein is considered by many a “superfood.” It typically contains immune-boosting immunoglobulins and lactoferrin, as well as branched-chain amino acids. Research shows branched-chain amino acids (leucine, isoleucine, and valine) found in whey have longevity benefits.1

Whey is a rich source of dietary cysteine. This amino acid is a precursor to glutathione, a powerful antioxidant which combats disease, aging, and oxidative stress.


Vegetable-Based Protein Options

While whey protein is perhaps the most popular protein supplement, many health enthusiasts are now turning to vegetable-based proteins. The combination of pea, and rice proteins, for example, are comparable to whey protein in digestibility and absorption.

In addition, vegetable-based proteins offer a variety of health benefits. Pea protein and other plant-based proteins have been shown to exert a positive impact on blood pressure and blood lipid levels.2-3
