Wikipedia says nutmeg is a hallucinogenic, which is nice, but eating just 0.2 oz of that stuff could lead to convulsions, and 0.3 oz will probably give you a seizure. Don’t ask what will happen if you eat a whole jar of the stuff. Because the answer is “R.I.P.”
No, not the tuna! Anything but the tuna! Tuna meat is dangerous because of the mercury that the fish absorbs. There are 2 ways this nasty chemical element can go while inside your body: it either passes through your kidneys, OR goes all the way up to your brain, which can supposedly drive you insane. For this reason the FDA recommends children and pregnant women to not consume tuna at all. Just to be on the safe side.
I can hear Ireland scoffing at this one. Taters can kill you? What a load of horse dung! Alas, just like with tomatoes, it’s the extremities that are harmful to us. Glycoalkaloids can be found in the leaves, stems, and sprouts of potatoes. Eating this chemical will lead to cramps, diarrhea, headaches, or even coma and death. Boy, that escalated quickly.
