Common Foods That Can Become Toxic When Eaten in Excess

Many foods contain natural chemicals, minerals or environmental contaminants that the body handles safely in ordinary amounts. Problems arise when portions become extreme, consumption is repeated too frequently or the food is prepared incorrectly.

“Toxic” does not mean these foods must be avoided completely. For most people, sensible portions are harmless; the danger depends on dose, preparation, age, pregnancy, medication use and existing health conditions.
