Antinutritious Beans

Beans the not so magical fruit. What are we talking about here? Black bean, black-eyed peas, fava beans chick peas, green beans, kidney beans, lentils, lima beans, navy beans, peas, peanuts, pinto beans, and soybeans. Raw beans are especially mischievous. Raw red kidney beans can set you off into nausea; vomiting, abdominal pain, severe diarrhea, muscle weakness, and heart inflammation (just wait until we get to lima beans).

Big misperceptions is that they are good sources of protein. Wrong, they’re a good 60% shy of their meat counterparts. We also are under the assumption that they are high in nutrients (notably zinc and iron). Wrong. They are full of antinutrients. Beans contain:

  •  Lectins
  •  Saponins
  •  Phytate
  •  Polyphenols: tannins and isoflavones
  •  Protease inhibitors
  •  Raffinose
  •  Oligosaccharides (causes gas)
  •  Cyanogenetic glycosides (can turn into lethal poisons in our intestines. Cooking helps, but do not eat raw lima beans)
  • Favism glycosides (this is fascinating because it is a genetic defect that can cause favism, a lethal response to fava beans)

Beans and legumes are a poor source of protein and contain many antinutrients.
