Raw Vegetables
Eating raw vegetables in some other countries isn’t always the best idea. This is because the water used to clean the vegetables isn’t always clean, and the substances used during the growing process may not be the healthiest, as some countries, like China, don’t have strict limitations on pesticide use.
