  • Phenylalanine Food Sources

    Fruitarian foods high in amino acid phenylalanine, per 100 g (~1/5 lb): 

    • Spirulina, dried - 2777 mg 
    • Soybeans - 2122 mg 
    • Pumpkin or squash seeds - 1642 mg 
    • Peanuts - 1427 mg 
    • Kidney beans - 1370 mg

  • Phenylalanine

    Phenylalanine is an essential amino acid.

    Provided by diet, phenylalanine can be converted into another amino acid, tyrosine, in the body. Tyrosine is used to synthesize two key neurotransmitters that promote alertness: dopamine and norepinephrine. 

    It has 3 forms:

    • D-phenylalanine;
    • L-phenylalanine - most common, the form in which phenylalanine is incorporated into the body’s proteins;
    • DL-phenylalanine.

  • 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 .

Choline Recommended Intake from Seeds and Fruits

Choline is an essential vitamin-like (vitamin B4) nutrient, synthesized in human body, but not sufficiently.

The recommended adequate intake (AI) of choline is set at 425 milligrams (mg)/day for women and 550 mg/day for men.

Choline deficiency causes muscle damage and abnormal deposition of fat in the liver, which results in a condition called nonalcoholic fatty liver disease. Genetic predispositions and gender can influence individual variation in choline requirements.
