If you are looking for vegan sources of protein, there is no shortage of optionslike hemp seeds, chia seeds, and spirulina. But, the last time I checked, hemp seed cost $18 per pound! That seems like an incredibly expensive way to get protein on the vegan diet.
In our society, meat is synonymous with protein. So, it comes as a surprise to many people to learn that many plants are loaded with protein. Vegan protein sources are often superior to meat in many ways, such as containing more fiber and less (or no) cholesterol, saturated fats, and trans fats.
