To note: While these all contain protein, most of the foods under the ‘legumes and beans’ section are mostly a carbohydrate source, and most of the foods under the ‘nuts and seeds’ sections are mostly a fat source.

While there is absolutely nothing wrong with carbs and fats, I’d be predominantly focusing on the other sections for your main protein sources
