So I was checking out nightshades online cuz i was wondering why some folks are scared of them. I went to this site Delicious Organics and, thank the lord, they had already done all of the research. So what are nightshades? They are fruits…commonly mistaken as vegetables. Potatoes, Tomatoes, Egglants, and Peppers are all Nightshades. And they are not soooo shady after all. All info from: http://www.deliciousorganics.com/Controversies/nightshade.htm
Natural toxins are normal. However, we can consume the fruit or vegetable safely when proper precautions are taken.
There are superstitious beliefs about the nightshade family (Potatoes, Tomatoes, Peppers, and Eggplant) and how they may harm the immune system or be unfit to eat. Actually, many of the vegetables in the nightshade family are staples in one’s diet, particularly in the Middle East where Eggplant, Peppers and Tomatoes are eaten in abundance. These vegetables are also known for their great medicinal qualities. People following the macrobiotic diet don’t eat fruits, they are actually all fruits, in the nightshade family.
The nightshade family of foods do indeed have a potential toxin. This is mother nature’s way of protecting themselves from insect damage. The toxin is found in the green part of these vegetables. Proper choosing and storage can cut down these risks.

Potatoes should always be stored in a dark cool place and kept away from light. To be safe, any green part on the potato, including any growths, should be cut away before using. Don’t ever eat green potatoes , they contain the toxin solanine. Potatoes may turn green when exposed to light and you’ll see a green skin. Never eat the leaves or stems from a potato either.

Eggplant and Peppers should be ripe to avoid the toxin. That means no green Peppers and no green Eggplant. Green Peppers, though common, are actually just immature. When allowed to ripen they will turn a glorious red or yellow or orange or even purple. Green Peppers have a distinctive and strong flavor, not at all like the mature fruit which is sweet. There is, however, a variety of green pepper that is ripe when green. This is not the variety commonly found. The ones you find in most restaurants and grocery stores are red bells that are harvested at the unripe green stage.

Green Tomatoes have this toxin, glycoalkaloids. These toxins cause them to have a bitter taste to be unappealing for consumption. Although a delicious southern food (fried green Tomatoes), we should not consume green Tomatoes. And never eat the leaves or stems of Tomatoes.
