Is yogurt healthy?
Yes, go ahead and add yogurt to your healthy foods list if you haven't already. Whether you choose plain, Greek, flavored or low-fat, yogurt is a nutrient-packed snack that nourishes you with a generous amount of calcium and protein, along with B vitamins and minerals, including potassium, phosphorus and magnesium.
A single 8-ounce cup of plain low-fat yogurt delivers more than 400 milligrams of calcium -- that's close to half of your daily needs.
Yogurt is made from milk fermented with the bacteria Lactobacillus bulgaricus and Streptococcus thermophilus. These beneficial bacteria, also known as probiotics, help preserve yogurt and improve its taste. (Other probiotics are often part of the microbial culture used to make yogurt and are usually listed on the ingredient statement, but L. bulgaricus and S. thermophilus are required).
Probiotics help digest the milk sugar lactose, making yogurt often tolerable by those who can't eat dairy foods. In addition to supporting digestion, research suggests that probiotics in yogurt may boost the functioning of the immune system.
