Okay kiddo, a food riot is when lots of people get very angry and upset about not having enough food to eat. Just like how you might get cranky and upset when you're really hungry, except on a bigger scale. It usually happens when there's a shortage of food or the prices of food go up too much. Imagine if the price of ice cream suddenly became really expensive and your mom and dad couldn't afford to buy it for you anymore, you might get upset too. But imagine if this happened to lots of families and they couldn't afford to buy any food at all, they might get really angry and start protesting or even fighting for food. It's a really scary and sad thing to happen, which is why it's important to make sure everyone has enough food to eat.
