A person with a vegan diet does not eat meat, eggs, or dairy. While some people may think this heavily restricts their sources of protein, there is still an abundance of vegan-friendly protein they can consume.
Having a vegan diet means that a person cannot take in protein from the same sources as a person with an omnivorous diet. An omnivore is a person who eats both animal and non-animal products.
However, there are many plant-based sources of protein that a vegan person can consume. Nuts, grains, and legumes are protein sources, and they also contain additional nutrients that are beneficial to the body. Certain vegetables and seeds also contain good amounts of protein.
This article will cover how much protein a person needs, why it is important, and what vegan foods are good sources for that protein.
A person’s protein requirements are based on several categories, including age, sex, weight, and physical activity.
According to Dietary Guidelines for Americans (DGA), protein is required in the following daily amounts for different groups of people:
|Age (years)-sex group||Recommended daily allowance (RDA) of protein (g)|
These RDAs are guidelines only, and a person may find that their personal requirement varies. In general, the RDA for a young and healthy person who does not do much exercise is
A person who is quite active, or who wants to build muscle, may find that they require more protein per day. An article in the
Additionally, a person who is pregnant will need to consume more daily protein. According to an article in the online journal Nutrients, a pregnant or lactating person should increase their daily protein intake by 10%.
There are many foods that are good sources of vegan protein, such as:
A whole grain is a grain that contains the entire grain kernel, meaning that the grain is intact. Many whole grains are good sources of protein, including:
When fried, seitan has
Certain vegetables are good sources of protein, such as:
Although not high in protein by itself, when used as part of a meal, broccoli can increase the protein content. Raw broccoli contains
Additionally, mycoprotein is a source of protein derived from fungi. People often use mycoproteins in meat substitutes. Mycoprotein contains 11g of protein per 100g.
However, certain products that contain mycoprotein also contain egg, which makes them non-vegan. A person should be careful to check the ingredients in a mycoprotein dish before eating it.
Pulses and legumes
Certain pulses and legumes are good sources of protein, such as:
There are many dishes that use chickpeas as an ingredient, such as curries and hummus. Hummus is also a good source of protein, containing
Additionally, peanut butter contains
Soybeans themselves contain
Fried tofu contains
When cooked, tempeh contains
Nuts and seeds
Many nuts and seeds are valuable sources of protein, including:
Almond butter contains 20.96g of protein per 100g, and 6.71g per 2 tablespoon serving.
Protein is an important nutrient present in various foods. Protein provides the body with energy, and is necessary for:
- proper growth and development
- building and repairing body cells and tissues
- hair, skin, nails, muscle, bone, and internal organs
- almost all body fluids
- many body processes, such as blood clotting
Proteins contain strings of smaller units called amino acids. The order of the amino acids determines the protein’s function and structure.
There are 20 types of amino acid, which fall into two categories:
Essential amino acids: These are amino acids that the body needs but cannot produce. There are nine essential amino acids that the body can only get through food.
Nonessential amino acids: The body can produce these amino acids via the consumption of essential amino acids, or through breakdown of body proteins.
The proteins taken by different foods also fall into separate categories:
Complete proteins: These foods contain all the essential amino acids in acceptable amounts. Foods such as quinoa, soy products, and mycoprotein are complete protein sources.
Incomplete proteins: These are foods that only contain some of the nine essential amino acids. Nuts, beans, seeds, and vegetables are incomplete proteins.
Complementary proteins: These are incomplete protein sources that, when eaten together at a meal or over the course of a day, combine to provide all nine essential amino acids. When people eat peanut butter with whole wheat bread, they form a complete protein.
It is possible for a person to have too much protein in their diet. Research suggests that for most people, eating more than 2g/kg/d could cause long-term health problems.
A person with too much protein in their diet may have the following symptoms:
- intestinal discomfort
- excess amino acids in the blood
- excess ammonia in the blood
- high levels of insulin
- liver and kidney failure
- increased risk of cardiovascular disease
Overconsumption of protein can also increase a person’s risk of developing:
There are many protein sources available to a person with a vegan diet. It is important that a person eats a good mix of protein sources. The amount of protein a person needs can depend on their age, sex, and level of activity.
