Plant-based diets can meet and exceed protein needs at every life stage
McHugh J, Sundermann M, Mock A, Bernstein M
Plant Based Nutrition
The beans, lentils, and sunflower seeds you're growing or buying aren't just a side dish, they're a legitimate protein backbone that can support muscle, fertility, and healthy aging just as well as meat.
Doctors have long assumed you need animal foods to get enough protein, but this review shows that a diet centered on plants, think lentils, chickpeas, tofu, whole grains, nuts, and seeds, can easily hit and even beat typical protein targets. On top of that, eating this way is linked to a healthier gut, less inflammation, and lower rates of heart disease, diabetes, and depression.
Key Findings
Standard protein RDA is 0.8g/kg/day, but well-planned plant-based diets can exceed this using legumes, soy, grains, nuts, and seeds
Whole-food, plant-predominant diets are linked to reduced cardiovascular disease, diabetes, cancer, and depression risk via improved microbiome diversity and short-chain fatty acid production
Adequate, well-distributed plant protein supports fertility, fetal growth, lactation, and lean muscle mass preservation through perimenopause and aging
chevron_right Technical Summary
A review of lifestyle medicine research finds that plant-based diets built from legumes, soy, grains, nuts, and seeds can supply plenty of protein, often more than the standard recommended amount, while also lowering the risk of heart disease, diabetes, cancer, and depression.
