All about fruitarianism with a long-term fruitarian, Lena

"Lean meat" is a misleading term. I noticed many times in conversations that people who think that they eat "proteins" tend to think about this food group as an almost pure protein, a perfect set of essential amino acids. Especially if they consume so called "lean meats." 

In beef (presented as "90% lean meat") - half of the calories are from fat (http://nutritiondata.self.com/facts/beef-products/6193/2). Even in the leanest bird meat approximately the fifth of the energy is from fat, ~18% in the leanest I could find (http://nutritiondata.self.com/facts/poultry-products/704/2).

Digestibility-corrected amino acid score (PDCAAS) of protein in beef is only 0.92, chicken - 0.91(?), and egg whites and soy - 1 or 100% (not that it matters much). Note, that 62% of calories in a whole egg are from fat, and 40% in soybeans. 

Percy Bysshe Shelley

They are called into existence by human artifice that they may drag out a short and miserable existence of slavery and disease, that their bodies may be mutilated, their social feelings outraged. It were much better that a sentient being should never have existed, than that it should have existed only to endure unmitigated misery.

All Known Essential Minerals

Minerals (nutrients) are inorganic substances (contain no carbon) that are necessary for normal body function and development.

Macrominerals

Macro-minerals are needed in large doses (approximate recommended daily intake, milligrams (mg) per day ): 

  1. potassium, K (3500 mg) - metal, ions are necessary for the function of all living cells; 
  2. chloride, Cl− (3400 mg) - essential electrolyte in all body fluids; 
  3. sodium, Na, natrium (2400 mg) - metal, essential for all animals and some plants;
  4. calcium, Ca (1000 mg) - metal, essential for living organisms, produced in supernova nucleosynthesis;
  5. phosphorus, P (1000 mg) - in the form of the phosphate is required for all known forms of life; 
  6. choline (425 - 550 mg) - essential vitamin-like (vitamin B4) nutrient, synthesized in human body, but not sufficiently;
  7. magnesium, Mg (350 mg) - metal, essential for all known living organisms;

Trace Minerals

Trace minerals are needed in very small amounts (recommended daily intake, milligrams (mg) or micrograms (mcg) per day: 

  1. iron, Fe (15 mg) - metal, found in nearly all living organisms;
  2. zinc, Zn (8 - 11 mg) - metal, essential for humans and other organisms;
  3. manganese, Mn (5 mg) - metal, toxic essential trace element;
  4. fluorineF, fluoride ion, F− (3 - 4 mg) - a beneficial poisonous element, essential for bone solidity;
  5. copper, Cu (2 mg) - metal, essential to all living organisms;
  6. iodine, I (150 mcg) - a key component of thyroid hormones;
  7. selenium, Se (35 mcg) - toxic in large doses, essential micronutrient for animals;
  8. chromium, Cr (30 mcg) - chromium (III) is questionably essential for humans.
