Yogurt to the rescue!
Has a doctor ever suggested that you "Eat some yogurt!" when you’re sick and taking antibiotics? It’s a smart thing to do. Yogurt is chock-full of protein, vitamins, and calcium. It’s also a superb source of good, helpful bacteria. Another word for these good bacteria is probiotics.
The good bacteria found in yogurt are known as live cultures. That means they are still alive when you eat them. Yogurt usually contains a few different kinds of microbes. It’s made under controlled conditions to allow only the good bacteria to grow. Letting in bad bacteria might spoil the food and make it taste bad, or even make you sick. The reason to eat probiotics after being treated with antibiotics is simple. You recharge your digestive system with a new batch of good bacteria.
