Understanding Protein in a Vegetarian Diet

Why Is Protein Important for a Balanced Diet?

Protein is an essential source of amino acids, which help support and regulate the immune system and metabolic processes within the body.

Also a contributor to building muscles, bones, skin, hair, and internal organs, protein carries oxygen through the bloodstream and is part of hemoglobin in red blood cells.

How Much Protein Do You Need Each Day?

The recommended dietary allowance for protein needed daily is 0.8 grams per kilogram of body weight.

Depending on your age, weight, or health, protein should make up 10% to 35% of the total daily calories consumed each day.

What Are Essential Amino Acids?

Essential amino acids include 9 building blocks of protein that the human body cannot create by itself and only receives from food.

• Histidine: Supports immune function and digestion
• Isoleucine: Aids muscle metabolism, immune function, and regulates energy.
• Leucine: Assists protein synthesis, growth hormones, and muscle tissue repair.
• Lysine: Important for the production of hormones and energy, plus calcium absorption.
• Methionine: Helps metabolism, detoxification, and tissue growth.
• Phenylalanine: Plays an important role in dopamine and adrenaline processes (both neurotransmitters).
• Threonine: Assists collagen and elastin production within skin and connective tissue.
• Tryptophan: Functions as a precursor for serotonin, which regulates mood and sleep.
• Valine: Supports muscle coordination, tissue repair, and energy generation

What Is a Complete Protein?

A complete protein is any food that contains all 9 essential amino acids.

Our bodies use 20 amino acids in total, but can only make 11 of the 20 on their own. These 11 are called nonessential amino acids.

Can You Get Enough Protein From a Vegetarian Diet?

Yes, it’s possible to eat enough protein from a vegetarian diet.

You can get enough protein by eating legumes (beans and lentils), soy-based foods (tofu and tempeh, along with soy milk), nuts and seeds, and whole grains (quinoa and farro).

What Is the Difference Between Plant-Based Protein and Animal-Based Protein?

Animal-based proteins are considered complete proteins, while proteins in a plant-based diet are not. 

In addition, the body absorbs animal-based proteins much more quickly and completely than it does plant-based proteins.

Best Vegetarian Protein Sources

What Vegetarian Food Is High in Protein?

Seitan has the highest amount of protein among vegetarian foods, with 25 grams of protein per 3-ounce serving.

It’s easy to add seeds to your morning Greek yogurt parfaits, oatmeal, or cereal, or to a salad, stir-fry, meatballs, or bread.

Are Oats a Good Source of Protein?

Oats are a good source of protein, with about 5 grams per 40-gram serving.

How Do You Combine Foods to Get Enough Essential Amino Acids?

Combining foods like grains and legumes (for example, rice and beans) works because grains are low in lysine, an essential amino acid, while beans have a higher amount.

Complementary proteins means pairing foods that together add up to a higher amount of essential amino acids.

How to Get 100g of Protein a Day as a Vegetarian?

You can reach 100 grams of protein per day on a vegetarian diet by eating high-protein foods that are plant-based, along with dairy and eggs.

Why Should You Pair Protein With Fiber and Whole Grains?
