Protein combining

Misc notes

• Most grains and legumes are "incomplete" proteins. [Exceptions]Complete proteins: ~ Soybeans ~ Quinoa ~ Chick peas, according to some studies ~ And possibly others...
• In most contexts, incomplete proteins are still just as useful, because they form complete proteins when mixed together.
  • Example: 20g protein from wheat and 20g protein from lentils does in fact make 40g complete protein.

TODO: Describe this in terms of amino acids and their amounts. Bar chart examples may be needed.
