Yogurt can also decrease your risk of contracting colon cancer, because it contains lactobacteria. Lactobacteria is 'good bacteria' because it helps to keep your colon clean and free of wastes, while aiding in digestion. Yogurt is also a rich source of calcium, as most dairy products are. Calcium aids in the development of strong teeth and gums, and can make your bones less brittle, which reduces the risk of developing osteoporosis.
Eating yogurt on a regular basis can help you to absorb the nutrients in other foods as well. For example, eating yogurt helps the body to absorb calcium and B-vitamins more readily, so you can get the most nutritional value out of your meals. In turn, yogurt can also boost your immune system, since you are able to take in the maximum nutritional value of foods, which makes your body better equipped to fight off toxins.
