Spinach, sweet potatoes, sprouts: NOT health food
The eating plan I follow is called The Original Diet.
The plant foods in this eating plan are very carefully chosen to follow clues from nature as to what she evolved humans to eat. In particularÂ, I avoid foods that are high in anti-nutriÂents placed there by her to discourage consumptioÂn by primates. For an overview of the subject, see plants bite back on westonaprice.org.
One example is spinach. Although it is seen by many as a super health food, it’s actually extremely high in oxalates, second only to soy, and oxalates are not destroyed by cooking. They can form nasty crystals throughout the body, including the kidneys and heart. For details, see oÂxalates in autism anÂd chronic disorders also at westonaprice.org.
Sweet potatoes contain invertase and protease inhibitorsÂ, which can interfere with digestion, although cooking can reduce the inhibitors somewhat. There is evidence that nature has placed anti-nutriÂents in at least some species of sprouts as well.
Probably the most studied in this category are alfalfa sprouts. There are reports of animal and human consumptioÂn of alfalfa sprouts, seeds, and supplementÂs causing lupus-like symptoms. One hypothesis for a culprit is the concentratÂion of canavanineÂ, a non-proteiÂn amino acid. UndoubtedlÂy, there is a dose related response, and perhaps some genetic susceptibiÂlity. Using the precautionÂary principle, I can take a hint, and won’t go near the stuff.
Fooling with nature is always a losing propositioÂn.
