  • EAR and RDA for Amino Acids

    Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA) for amino acids (protein) for healthy adults 19 y and older, mg/kg/day:

    • Estimated Average Requirement (EAR): average, estimated to meet the requirements of 50%.
    • Recommended Dietary Allowance (RDA): average, sufficient to meet the nutrient requirements of nearly all.
    Amino Acids EAR RDA
    phenylalanine + tyrosine 27 33
    valine 19 24
    threonine 16 20
    tryptophan 4 5
    methionine + cysteine 15 19
    leucine 34 42
    isoleucine 15 19
    lysine 31 38
    histidine 11 14
  • Amino Acid Requirements for Adults

    Estimates of Amino Acid Requirements for adultsmg / kg per day

    • Phenylalanine + tyrosine: 14
    • Leucine: 14
    • Methionine + cystine13
    • Histidine: 8–12
    • Lysine: 12
    • Isoleucine: 10
    • Valine: 10
    • Threonine: 7
    • Tryptophan: 3.5

  • All Essential Amino Acids

    An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized by the organism, and must be supplied in diet. 

    The 9 amino acids humans cannot synthesize (F V T W M L I K H):

    • phenylalanine
    • valine
    • threonine
    • tryptophan
    • methionine
    • leucine
    • isoleucine
    • lysine
    • histidine

    Animal and plant proteins are made up of about 20 common amino acids.

    Synthesis of 6 other amino acids - conditionally essential - can be limited under special conditions (R C G Q P Y)arginine, cysteine, glycine, glutamine, proline, and tyrosine.

    Dispensable amino acids can be synthesized in the human body, 5 (A D N E S): alanine, aspartic acid, asparagine, glutamic acid and serine .

I have from an early age abjured the use of meat, and the time will come when men such as I will look upon the murder of animals as they now look upon the murder of men.


Grains are small, hard, dry seeds, with or without attached hulls or fruit layers, harvested for human or animal consumption. The two main types of commercial grain crops are cereals (e.g. wheat, rye) and legumes (e.g. beans, soybeans). Seeds

After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (e.g. plantains, breadfruit) and tubers (e.g. sweet potatoes, cassava). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported, stored for long periods, and milled for flour or pressed for oil. Major global commodity markets exist for canola, maize, rice, soybeans, wheat, and other grains but not for tubers, vegetables, or other crops. Apple
