Eating yogurt does offer health benefits, but like many other foods, eating too much does pose adverse effects. Consuming too much yogurt reduces the nutrients the body needs on a daily basis.
Yogurt is a high calcium food and ingesting too much calcium can create problems, including prostate cancer and kidney stones. Ingesting large amounts of calcium can also cause a build-up in the blood vessels.
A container of yogurt contains high levels of bacteria, which if ingested in large amounts can create digestive issues. Issues range from diarrhea, bloating, gas and sour stomach.
Yogurt is a healthy food when it is eaten in moderation.
