This is a viral question and an important one, as it reveals an underlying misconception about nutrition. But even if you aren’t following a plant-based diet, do you know how much protein you should be eating daily?
Although protein is certainly an essential nutrient that plays many vital roles in our body’s function, we do not need vast quantities of it. Protein is not a case in which more is better. With the popularity of high-protein diets, you may believe that you can’t overeat protein. But the truth is that consuming excess protein can actually be quite detrimental to your health.
What is protein?
Proteins are large molecules made up of chains of smaller molecules, called amino acids, found in the vegetable or animal protein worlds. There are twenty different amino acids that the body uses to make protein, eleven of which can be synthesized naturally by our bodies. The remaining nine, which we call essential amino acids, must be ingested from the foods we eat. So, technically, our bodies require certain amino acids, not protein per se. When you eat protein, your body breaks apart the amino and sends them to whichever part of your body needs whichever type of amino acid.
Like those with a higher health consciousness, most vegans and vegetarians have stories about why they decided to live their particular nutritional lifestyles. No matter the reasons, one of the challenges for non-meat eaters is making sure to consume enough protein every day. But it’s not as big of a deal as many think. Like most of the nutrients from quality food, a little goes a long way. Back in the hunter/gatherer days, primitive man ate a lot less meat—usually around 20% of his total diet—a far cry from how much the average American consumes daily in the 21st century.
More Protein Builds More Muscle
Protein promotes the muscle-building process, called protein synthesis, “but you don’t need exorbitant amounts to do this,” says John Ivy, Ph.D., co-author of Nutrient Timing.
If you’re working out hard, consuming more than 0.9 to 1.25 grams of protein per pound of body weight is a waste. Excess protein breaks down into amino acids and nitrogen, either excreted or converted into carbohydrates and stored.
How much, then, is just enough? In the United States, the Dietary Reference Intake (DRI) for protein is 0.8 to 1.0 grams of protein per kilogram of body weight. To calculate your weight in kilograms, divide your weight in pounds by 2.2. That number is about how many grams you need each day. Approximately 15-25% of your total calories should be from protein sources.
Plant-Based Protein Sources
In the early years, protein meant meat, and meat meant protein. But the nine essential amino acids are hardly the exclusive domain of the animal kingdom. Most people seem to think that plant-based protein sources don’t provide you with complete protein sources and that animal protein is needed for this. Still, several foods include all nine essential amino acids, making them complete protein sources. These include Quinoa, pumpkin seeds, chickpeas, and black beans. There are also lots of plant-based foods containing a mixture of essential amino acids, so by eating a variety of these delicious foods, you can consume all the essential amino acids. Your body will have everything that it needs.
