All You Need to Know About Plant-Based Proteins

Protein is an essential macronutrient that helps us maintain and build our muscles, bones, and hair, and perform other essential functions such as nutrient transport and enzymes. Contrary to popular belief, dietary protein is not exclusively found in meat, fish, and eggs. Protein foods also include beans, peas, lentils nuts, seeds, and soy products. Variety is essential to a healthy dietary intake, and protein is no exception. Whether you eat meat, or follow a vegetarian or vegan diet, incorporating plant-based proteins is an essential part of a balanced diet. Much like their meat and dairy counterparts, plant proteins bring a variety of essential nutrients to the table, such as vitamins, minerals, fibre, healthy fats, and phytonutrients. 

Benefits beyond the protein

Most people consuming the Western diet get the protein they need from meat, poultry, and eggs, but do not meet the recommendations for other forms of protein like seafood, nuts, legumes, seeds, and soy. The plant-based proteins increase the amount of essential nutrients in your diet, such as fats, dietary fiber, vitamins, minerals, and phytonutrients. Mixing in plant-based proteins can also help limit the amount of sodium and saturated fats (nutrients generally consumed in excess) people get from eating processed meats like deli meat or jerky. 

In addition to our physical health, shifting to a more plant-based diet is good for planetary health. About half the world’s habitable land is being used for food production, the majority of which is used to raise livestock (and the feed used to support livestock). Shifting to a plant-rich diet can significantly reduce the negative environmental impact of food production on our planet. 

Complete vs Incomplete Plant Proteins

There are twenty amino acids that serve as the “building blocks” of protein. Nine of these amino acids are considered to be essential, which means our body cannot make these on its own, and therefore we must obtain them through the diet. Foods that are considered “complete proteins” are defined as any food that provides all nine of the essential amino acids. Some examples of plant-based foods that are complete proteins include:

• Quinoa 

• Soy (like tofu, tempeh, edamame)

• Chia seeds 

• Buckwheat

• Hemp seeds

Not every protein you eat has to be complete on its own- you can pair to sources of plant-based protein to achieve a complete profile of all nine amino acids. Examples of these pairings include: 

• Rice + Beans (in a bowl, or even as part of a burrito)

• Peanut butter + Whole grain bread (a morning toast!)

• Chickpeas + pistachios (in a delicious salad!)

• Peas + Pasta (especially delicious paired with a creamy sauce)
