Protein

Protein is a relatively simple macro to discuss depending on how in depth you want to discuss it.

Protein is generally either looked at as red meat or white meat.

But then you have to consider sources of protein from diary, your milk, eggs, and cheese, not to mention sources from your different yogurts.

Then you can discuss protein in more depth if you want to discuss protein sources limited to a vegetarian / vegan diet, something I know little about. The extent of knowledge is that if you mix the carbohydrates rice and beans with one another that, that makes for a complete protein. If you need or want to talk to someone who knows more about those diets, then I encourage you to seek for someone else. Because I am neither a vegetarian nor a vegan but do understand that you can find some good sources in powder form now that may be able to help you out.
