If you’re following a plant-based diet, you may be wondering where to get your protein from. While meat and animal products are often seen as the main sources of protein, there are plenty of plant-based sources of protein that can provide all the protein your body needs. In this article, we’ll explore some of the best sources of plant-based protein and why they should make up a major part of your daily diet.
According to a study in the Journal of the Academy of Nutrition and Dietetics, even vegetarians and vegans consume about 70% more protein than needed, every day. (1)
What is actually lacking in the average American diet? Fiber. The U.S. Department of Agriculture and Agricultural Research Service identified that less than 3% of Americans consume adequate amounts of fiber (3).
Yet, despite the lack of fiber and other nutrients deficient in the average American diet, our shelves are packed with packaged and processed foods with added protein. Protein granola bars, powders, cereals. Even protein added to some yogurts.
Trust me, I get it. I too once thought an adequate amount of protein needed to come primarily from animal sources. Or, that drinking cow’s milk with dinner was the healthiest thing for me. Thinking Greek yogurt was one of the healthiest snacks I could have. I would even order a side of sausage patties with my white flour pancakes at Sunday brunch thinking it would round out my breakfast treat to make it more “nutritious”. Boy, was I wrong.
Unfortunately, high consumption of animal proteins are associated with increased risk for:
A study published in 2014 found that high protein diets for those between the ages of 50-65 had a 75% increase risk in overall mortality and four-times more likely to die from cancer within the next 18 years. Astonishingly, the study also found that if the protein intake was derived from plant-based proteins, the association (or risk of mortality and cancer) was eliminated or weakened.
That is right. You did not read it wrong. According to this study, if you consume an excessive amount of plant-based protein, the risk of death and cancer no longer existed, or was weakened.
In addition, the study found a high protein diet increased diabetes across all ages by five-times (6). And here, this whole time we thought the cause of diabetes was high carbohydrate intake. There is more to that story too—we will cover that in a future post.
If animal proteins increase risk for several types of diseases, where should one then source their protein from? Plants.
In my post, Healthiest Diet, I discuss a diet that is focused on whole, plant-based foods. This diet is centered around fruits, vegetables, whole grains, legumes, with some nuts and seeds. All whole foods contain protein–some greater than others.
It is true that a “vegan” diet that includes high amounts of processed foods, such as white pasta and Oreo cookies, will not provide sufficient protein intake, nor will it provide sufficient overall nutrient intake.
However, a diet focused on a whole, plant foods will supply adequate amounts of protein (and other necessary nutrients!), while including a wide range of nutrients (such as phytochemicals) which have been shown to reduce one’s risk of cancer and chronic disease.
