What sources of protein are best? In terms of amino acid balance, the best sources are eggs, quinoa, soybeans, meat, fish, beans and lentils. In addition, many nuts, seeds, and vegetables like green beans, peas, corn, asparagus, brussells sprouts, cauliflower, spinach, okra, and broccoli have good levels of protein—these are best eaten with a whole (unrefined) grain for maximum protein absorption.

Animal protein sources tend to have more saturated fats, so it is best to choose the leanest cuts possible, in portions of 4-6 ounces. Some people can tolerate meats well and digest them thoroughly (people with blood type O most often fit into this category), but others, especially if they have kidney issues or systemic inflammation, may find that limiting animal products serves them better. Vegetable protein sources tend to contain additional beneficial complex carbohydrates and are less acid-forming (and therefore less likely to cause inflammation, mineral deficiencies, auto-immune disorders).

Signs you are not absorbing adequate protein may include:
• menstrual cycle problems, infertility, painful or skipped cycles
• problems with TMJ, clicking sound or pain in the joint of the mouth
• scattered thoughts or the inability to “shut off” your brain
• feeling “wired” all the time, even when not ingesting caffeine
• bleeding gums
• cold hands and feet
• depression
• excess saliva, watery eyes, general “too wet” condition

Protein digestion requires protease. If you are not digesting protein well, it will be important to supplement this crucial enzyme. We also need to have the proper pH in the gut and the correct concentration of stomach (hydrochloric) acid for complete digestion of proteins to occur. So stress (which interferes with HCl production) can be a real digestion inhibitor, as can drinking liquids with meals (especially cold drinks or those with lemon, which is alkalinizing to the system).
