A Guide To Plant-Protein & Amino Acids


Protein intake is crucial for repairing the muscle tissue that is worked during training sessions. Working the muscles creates micro-tears in the muscle tissue that need to heal before muscles can continue to grow. Proteins are necessary for the latter, as they are essentially building blocks for body tissues.

By eating the right amount of protein, your muscles will be able to recover and improve. Consuming enough calories and protein daily is crucial for hypertrophy, the increase of strength and size of muscles. Simply put, recovery and repair help your body adapt to an exercise.

How much protein do you need?

The recommended intake (DRI) of protein is 0.5-0.8 grams per pound of bodyweight, or 1.2-1.7 grams per kilogram for gaining muscle. Depending on your goals, consuming a slightly higher amount of protein during a cut will help to minimize the loss of muscle tissue.

Protein, depending on the source, is made up from different amino acid profiles. Amino acids compose many of the body’s structures including nails, muscle, skin, and hair. 11 of the total 20 amino acids can be synthesized by the body and don’t have to be obtained from food. The other 9, however, need to be present in your diet. All of these amino acids play a different role inside the body and even though only 9 are essential, a complete diet that includes all the 20 amino acids can enhance both your workout performance and recovery. Amino acids are also required for the production and availability of hormones in the body, which facilitate a number of vital functions in the body.

All 20 amino acids can be obtained from plant-based ingredients. Every ingredient that can supply the body with protein has a different amino acid profile. The nine essential amino acids are leucine, lysine, tryptophan, isoleucine, histidine, valine, methionine, phenylalanine, and threonine.

Beans and legumes contain high levels of lysine but are lacking in methionine. Examples include kidney beans, peanuts, peas, black beans, lentils, and garbanzo beans. These sources can therefore be combined with grains such as rice that are high in methionine. Leafy greens like spinach, kale, broccoli, and romaine lettuce are high in leucine, valine, phenylalanine, and lysine.

A couple of exceptional plant foods are soy and quinoa. Both contain a great balance of amino acids. Soy even contains all nine essential amino acids, making it a complete protein source. And unlike many internet articles claim, soy is a perfectly responsible ingredient on a plant-based diet (soy allergy excluded). Daily requirements for amino acids are not extremely strict, since it’s easy to get enough of every essential amino acid on a varied plant-based diet.

The following list is a breakdown of the nine essential amino acids, their functions, sources, and daily requirements:
