Top 10 Toxic Foods We Like To Eat

7. Potatoes

Potatoes are common item in many dishes. But all types of potatoes never become good for health. First of the leaves and stems of potatoes are toxic, green potatoes also make the same poisonous effect. Green potatoes contains toxic elements known as solanine. It is also need to keep in mind that potato chip-makers use greenish potatoes for the production. Excessive consumption of potatoes chips will definitely make you sick.



Solanine poisoning is primarily displayed by gastrointestinal and neurological disorders. Symptoms include nausea, diarrhea, vomiting, stomach cramps, burning of the throat, cardiac dysrhythmia, nightmares, headache and dizziness. In more severe cases, hallucinations, loss of sensation, paralysis, fever, jaundice, dilated pupils, hypothermia, and death have been reported.

Ingestion of solanine in moderate amounts can cause death. One study suggests that doses of 2 to 5 mg/kg of body weight can cause toxic symptoms, and doses of 3 to 6 mg/kg of body weight can be fatal.

Symptoms usually occur 8 to 12 hours after ingestion, but may occur as rapidly as 10 minutes after eating high-solanine foods.

Solanum glycoalkaloids can inhibit cholinesterase, disrupt cell membranes, and cause birth defects. One study suggests that the toxic mechanism of solanine is caused by the chemical’s interaction with mitochondrial membranes. Experiments show that solanine exposure opens the potassium channels of mitochondria, decreasing their membrane potential. This, in turn, leads to K+ being transported from the mitochondria into the cytoplasm, and this increased concentration of K+ in the cytoplasm triggers cell damage and apoptosis.
