Yogurt is known for its wonderful probiotics. It has been linked to stronger immune systems, lowered risk for gum disease and some cancers, and a healthier GI tract. You can also ward off yeast infections, improve symptoms of gas, bloating, constipation and diarrhea. Some studies even link non-fat yogurts with weight loss due to its great balance of carbs and protein which helps curb hunger.
Keep in mind that in order for the probiotics to be effective, you need 100 million cultures per gram. Yogurts with the National Yogurt Association's Live and Active Cultures seal are a guarantee of this. Also, sweetened yogurts can have up to 25grams of sugar. The natural sugar in yogurt is about 12 grams. Every 4 grams on top of that is an added teaspoon. Instead, buy plain yogurt and sweeten with honey. The honey actually helps the probiotics thrive!
