Why Do We Need Protein?

As humans, we need protein in order for our bodies to function properly and remain healthy.

facts about protein

Protein plays an important role in ensuring that our body has enough energy. It also helps with the transport of oxygen in the blood throughout our body [2].

How Much Protein Do We Need?

To prevent the tissues in our body from breaking down and the loss of muscles, we have to ensure that we are consuming enough protein each day. That being said, moderation is key. Ensuring that we consume enough protein is one but we also need to be mindful to not over-consume protein. Excess protein will be converted and stored as fats.

According to U.S. Dietary Guidelines by the U.S. Department of Agriculture and U.S. Department of Health and Human Services, adults should aim for protein to make up 10–35% of their daily calorie intake [5]. The general recommendation is 0.8 grams of protein per kilogram of body weight [4].

How Do Vegetarians Get Protein?

For vegetarians, getting their source of protein is not as straightforward as someone without any diet restrictions. Vegetarians generally consume plant protein and no meat, poultry, fish, or any animal-derived products (with the exception of milk, dairy products, and eggs).

Thus, those on a vegetarian diet will have to turn to these alternative sources of protein instead.

2. Oats


Oats are another great choice if you are looking for a plant-based option that provides a good amount of protein. Half a cup (40g) of dry oats provides approximately 5g of protein. At the same time, they provide a ton of good minerals such as zinc, phosphorus, folate, and magnesium.

Hemp seeds are considered as a complete protein source. In order to be a complete protein, the food has to contain all nine essential amino acids that the body is not able to produce on its own [3]. In this case, hemp seeds satisfy this criterion!

Besides that, hemp seeds are also rich in omega-3 fatty acids, fiber, and other vitamins. A 30g serving gives you roughly 9g of protein.

5. Beans

But that’s not all, research also shows that a diet rich in beans can potentially decrease cholesterol levels and manage blood sugar levels.

This is a great alternative for individuals who are just starting out on a vegetarian lifestyle.


In summary, being on a vegetarian diet doesn’t mean that you cannot have delicious and nutritious foods. It is the same as a normal diet with no restrictions, just that the difference is only being able to consume plant foods and a couple of animal-based products. You can still get a good amount of protein from plant foods, eggs, and dairy. So, don’t be afraid to try!
