Antinutrients

  • Common Plant Toxins

    Food plants are known to produce a wide array of chemicals. The levels of many of the more toxic ones have been reduced by hybridisation, but many of these natural toxins are still present at low levels. Eating very large amounts of one type of such foods can possibly be somewhat toxic.

    Common Plant Toxins and Antinutrients

    Toxins (occurrence in plant foods) - possible effect on humans and animals in large amounts:
    • Cyanogenic glycosides (sweet potatoes, stone fruits, lima beans) - gastrointestinal inflammation, inhibition of cellular respiration.
    • Glulcosinolates (canola, mustard, radish, cabbage, peanut, soybean, onion) - impaired metabolism, reduced iodine uptake, decreased protein digestion.
    • Glycoalkaloids (potato, tomato) - depressed central nervous system, kidney inflammation, carcinogenic, birth defects, reduced iron absorption.
    • Gossypol (cottonseed) - reduced iron uptake, spermicidal, carcinogenic.
    • Lectins (most cereals, soybeans, other beans, potatoes) - intestinal inflammation, decreased nutrient absorption.
    • Oxalate (spinach, rhubarb, tomato) - reduces solubility of calcium, iron, and zinc.
    • Phenols (most fruits and vegetables, cereals, soybean, potato, tea, coffee) - destroys thiamine, raises cholesterol, estrogen-mimic.
    • Coumarins (celery, parsley, parsnips, figs) - light-activated carcinogens, skin irritation.

Zinc

Zinc is a nutritionally essential mineral needed for catalytic, structural, and regulatory functions in the body.

The RDA (recommended daily allowance) for adult women and men is 8 mg a day and 11 mg a day of zinc, respectively.

Severe zinc deficiency is a rare, genetic or acquired condition. Dietary zinc deficiency, often called marginal zinc deficiency, is quite common in the developing world, affecting an estimated 2 billion people. Zinc deficiency can cause impaired growth and development in children, pregnancy complications, immune dysfunction, and increased susceptibility to infections. Long-term consumption of zinc in excess of the tolerable upper intake level of 40 mg a day for adults can result in copper deficiency.

Zinc bioavailability is relatively high in meat, eggs, and seafood. Zinc is less bioavailable from whole grains and legumes due to the inhibitory effects of phytic acid on absorption of the mineral.
