Avoid Tomatoes if You Have Indigestion Problems

Tomatoes are one of the most popular vegetables in the U.S., but did you know that until 80 years ago, they were regarded as an oddity or even poisonous?  Though they have some useful vitamins and nutrients, they actually contain solanine (a glycoalkaloid poison found in species of the nightshade family).  This substance can upset your calcium balance, so tomatoes should be avoided by people with arthritis or osteoporosis. 

Here's what The New Whole Foods Encyclopedia has to say about them:

"Tomatoes are on the macrobiotic 'use almost never' list because they are too yin, too acidic, and therefore--with long term use--weakening to the gastrointestinal tract... The acids of green tomatoes are especially detrimental to the kidneys."
