Here are some of foods that are generally healthy and good to eat but can be harmful because of the toxins it contains:
- Peanuts and peanut butter
- Potatoes
- Rhubarb
- Kidney Beans
Peanuts are legumes that grown underground as part of a root system. And because of its direct contact on the soil makes it dangerous and harmful to the health. The change in the surrounding of the peanut produces fungus which releases a toxic substance called “aflatoxin”. This substance is considered as a cancer-causing agent that usually attacks the liver.
Potatoes contains natural toxin called “glycoalkaloids”. A high level of this toxin is usually found in green potatoes (potatoes that are exposed to UV light), potato sprouts, a lot of bruising and potatoes with bitter taste. Glycoalkaloids can cause severe stomachache and even death, in rare cases, and it's not destroyed by cooking. You can enjoy potatoes safely by avoiding any sprouts, green or damaged parts, or bitter-tasting portions.
Rhubarb is considered as a wonderful plant. It contains a naturally occurring oxalic acid. The levels differ depending on the age of the plant, climate, season and the type of soil. Oxalic acid poisoning can cause muscle twitching, cramps, decreased breathing and heart action, vomiting, pain, headache, convulsions and coma.
Eating just four to five raw kidney beans can cause severe stomachache, diarrhea and vomiting because of toxins called lectins. These toxins can also disrupt cellular metabolism. To get rid of the toxin, soak raw beans for at least five hour, and then boil them for at least 10 minutes.
