Is It Possible to Compete With Animal-Based Proteins?
This topic is addressed by Matt Frazie of The NoOrganifi Green Juice Review Meat Athlete. The Paleo Diet, as you know, is based on the principles of what we are "designed to eat." As such, it includes copious amounts of the animal-based products that vegans cannot eat. Frazie shows no hesitation in pointing out that it is simply impossible to follow the Paleo Diet as a vegetarian since every major vegetarian source of protein, including soy, beans, and quinoa are not allowed. However, he does point out that there are ways to slightly modify the Paleo diet in order to get those essential amino acids.
If you are a vegetarian that does not avoid eggs, then by all means eat eggs! They contain all nine essential amino acids as well as three essential fatty acids. You could actually meet all the protein requirements by simply including quality sources of this nutritious food.
Grain-like seeds such as quinoa, amaranth, and buckwheat behave more like grains than like nuts which is why most Paleo-style diets do not allow them. They contain mostly carbohydrates as opposed to other seeds such as sunflower seeds which contain mostly fat and protein. However, including these in your diet would definitely get you closer to meeting protein requirements for the day.
