Foods that become harmful when eaten too much

Star fruit, carrots, tuna... are very good foods for health. However, when used too much, these dishes can also cause unexpected harm to health.

1. Tuna

People who eat tuna regularly are at risk of mercury poisoning because this compound accumulates in the fish meat. Mercury can cause vision problems, neurological problems and slow development in young children. You should only eat tuna once a week to give your body time to eliminate toxins and prevent them from accumulating and causing illness in the body.
