This is called allopathy. All seeds contain phytates in their outer seed coats. When seeds are soaked and germinated, enzymes are created which will split and neutralize phytates. In addition to phytates, legumes contain other harmful ingredients that can be eliminated by sprouting and germinating and then heating. Raw soy beans have a substance that stimulates goitre, and also a trypsin inhibitor.
Trypsin is an enzyme necessary in the digestion of protein.
Lima beans have a toxicant, glycocide, which yields hydrocianic acid. Raw fava beans can lead to hemolytic anaemia. So always soak then throw away the water, germinate for 2 - 3 days, washing and draining, then heat before eating. The above figures are found in The Chemistry Of Youth , printed in 1977. Similar figures are found in Nutritional Science and Health Education , printed in 1978, but not in earlier editions of the above title by Dr Curtin Shears.
