What are Vegetable Proteins?

Vegetable Proteins

1. Soy and Tofu

It contains a high concentration of plant protein. It contains approximately 37g of protein per 100g and has low levels of saturated fat. Tofu, tempeh, and soy burgers are two good soy food alternatives that contain large amounts of protein, also contain large amounts of calcium, and iron. It is also advisable to prepare soups with soy, legumes, or chickpeas.

2. Quinoa

It is one of the best plant foods rich in protein. In one cup of cooked quinoa, we can find 18g of vegetable protein. Quinoa is considered a super cereal and also contains vitamins, minerals, carbohydrates, and a large number of amino acids. It helps reduce cholesterol and the risk of suffering from diabetes. It is also used in diets to control or reduce weight and helps control blood pressure.

3. Seitan

Made from wheat gluten, Seitan is considered“vegetable meat”. In addition to containing a percentage similar to meat protein (20g per 100g), it is practically cholesterol-free and is very versatile when cooking it. To increase its benefits it is possible to combine it with cereals to avoid possible nutritional deficiencies.

4. Legumes

Legumes, whether they are lentils, chickpeas, beans, or soybeans, are one of the plant-based foods with the highest protein content. Combined with some cereals, they provide high-quality protein comparable to meat. They are low in fat and contain large amounts of carbohydrates and fiber. One cup of lentils is capable of providing 18g of protein.

5. Rice

It is a basic and universal food. Its main benefits are the fact that it does not contain cholesterol or sodium, it is a complex carbohydrate, easy to digest and it also contains high-quality protein. Brown or wild rice has approximately 40% more protein than white rice. The absence of lysine in the amino acids present in rice can be compensated by combining it with other foods such as lentils and thus ensure a complete protein.

6. Chia seeds

Chia seeds are considered a “superfood”  given that due to their composition, it provides an important amount of fiber, antioxidants, vitamins, and essential fatty acids. They contain 23% protein, helping to regenerate muscles and tissues. Also, these seeds help in weight loss diets, growth stages and in the treatment of various diseases.

  • They do not contain lactose, a type of carbohydrate present in milk and therefore food of animal origin
  • They are easily digestible, so they do not cause gastrointestinal discomfort

Vegetable and Sports Proteins

Many people who practice sports, as well as a large number of athletes, lead vegan or vegetarian diets. In these cases, the supply of amino acids does not come from animal sources and has no repercussions on physical performance which, contrary to what one might think, is better. Many of these athletes compete at the Olympic level.

As for the protein requirement, that of those who play sports is greater than other people. Workouts are physical activities that cause a deterioration of muscle tissue, so it is necessary to supply substances that regenerate it, i.e. amino acids. Plant proteins are often deficient or have reduced amounts of amino acids. In these cases, it is necessary to consume various protein sources every day, in order to have the whole spectrum of amino acids necessary to perform the required physical efforts. Protein supplement powders will make this process easier.


In conclusion, vegetable proteins offer a multitude of benefits, including being a great source of essential amino acids, fiber, and antioxidants. They are sustainable and environmentally friendly, making them an excellent choice for those looking to reduce their carbon footprint. With their versatility and availability in various plant-based food sources, vegetable proteins are an essential component of a healthy and balanced diet for individuals seeking plant-based protein options.
