Here’s Even More Evidence That Plant Protein Is Better for You Than Animal Protein

It’d be great if a burger-a-day diet was healthy. Don’t get me wrong—it’s not the worst. You’ve got protein in there and hopefully some veggies on top (and on the side) , and even some fiber from the roll (you used whole grain, right?).

Unfortunately, study after study shows that meat as a protein source just isn't that healthy. It's far better to get that necessary protein from plants. Generally speaking, diets heavy on plant matter tend to be healthier. One study found that those eating the most fruit-and-veg-dense diets had a 31 percent lower risk of dying from cardiovascular disease and a roughly 20 percent lower risk of overall mortality than those eating animal-focused diets. That study didn't look specifically at protein, but participants consumed the other main animal-sourced food group, dairy, at about equal rates no matter what, so ultimately this comes down to replacing meat with alternative protein sources.

And yes, these associations are correlations, not causations. But there are some legitimate reasons that plant-based protein sources like beans are a healthier alternative to bacon. The researchers aren’t saying you can’t or shouldn’t indulge in a thick Delmonico or a flame-grilled cheeseburger. Rather that you should enjoy them in moderation. Generally, research shows that less animal meat—most especially red meat—is better than more, in terms of long term health. You don’t have to love tofu, either (it’s not the best plant-based protein anyway), as long as you strive to eat more of your protein from the ground and less from animals.

Here’s a deeper dive into why:

Plant Protein Has More Nutrients and Fiber (Though Not All of the Amino Acids)

Animal meat is known for its many nutrients. If you eat a variety of animal meats (light and dark, not just beef, as well as various organs), you can take in all the amino acids you need to manufacture your own bodily proteins plus vitamins like B12, niacin, thiamine, B5, B6, B7, and vitamins A and K.

But here's the thing: If you swap all that animal protein for an equally diverse diet of plant-based proteins like nuts, seeds, and beans, you are no worse off. That's because these foods are also packed full of a similar spectrum of nutrients. The biggest difference is vitamin B12, which most plants cannot produce on their own. You can get B12 from edible seaweed and in fortified cereals, though the easiest way is through supplementation or by eating animal products.

Given their equal vitamin profile, Andrea Giancoli, a registered dietitian in California says plant-based proteins are far healthier than their meat counterparts. That’s because, pound-for-pound, they pack more nutrients into fewer calories. They also have one thing that animal proteins completely lack: fiber. (Except for things like tofu, which is processed, Giancoli notes.) Let’s not forget the fiber. Fiber aids in digestion, promotes a healthy gut microbiome, and is strongly associated with lower cardiovascular disease risk.
People Who Eat Plant Proteins in Part Have Healthier Habits

Meta-analyses that compared people who eat animal versus plant proteins consistently find that, even after adjusting for other influential factors like socioeconomic class, weight, and exercise habits, those who eat plants tend to live longer, healthier lives. They tend to have less cardiovascular disease and fewer cancer cases, though especially the cancer association tends to drop away once other factors have been controlled for. Despite all that controlling, though, there's still an association with living a longer life with fewer heart problems. There are almost certainly some small factors contributing to the association. People who eat plant proteins may see their doctor more regularly and thus get better preventive care. Maybe they tend to live in quieter, less polluted places.

Since correlations still exist between eating plant proteins and overall health, even after controlling for other factors, meta-analyses have generally concluded that lifestyle factors alone can't account for the correlation. One such analysis in the Journal of the American Medical Association noted that "Substitution of plant protein for animal protein, especially from processed red meat, may confer a substantial health benefit" and advised that policies promote plant proteins.

I suspect people who have had issues with their vegan diets did not track their diets closely enough to make sure they were getting all the necessary amino acids and vitamins then?
