16 Best Foods for Plant-Based Protein Sources
As more people embrace plant-based diets for health, ethical, or environmental reasons, the need to find high-quality sources of plant-based protein has become increasingly important. Protein is essential for numerous bodily functions, including the maintenance of muscle mass, hormone production, immune system support, and tissue repair. While animal products like meat, eggs, and dairy are commonly known sources of protein, many plant-based foods offer just as much, if not more, nutritional value, without the saturated fats and cholesterol found in animal products.
In this article, we will explore the 16 best plant-based foods that are rich in protein. These foods not only provide protein but also offer an abundance of other important nutrients like fiber, vitamins, minerals, and antioxidants. Whether you are a vegan, vegetarian, or simply looking to add more plant-based meals to your diet, these protein-packed foods can help you meet your daily nutritional needs while promoting overall health.
1. Lentils
Lentils are one of the best sources of plant-based protein, with about 18 grams of protein per cooked cup (about 198 grams).
