Probiotics are a type of healthy bacteria that benefit the gut. They help regulate the digestive system and decrease gas, diarrhea, constipation, and bloating.
Some research has suggested that probiotics can boost the immune system, help with weight management, and reduce the risk of cancer.
Consuming yogurt and other probiotic foods may enhance absorption of vitamins and minerals.
The two most common bacteria used to ferment milk into yogurt are Lactobacillus bulgaricus (L. bulgaricus) and Streptococcus thermophiles (S. thermophiles), but many yogurts contain additional bacterial strains.
To help consumers identify yogurts with live and active cultures, the National Yogurt Association has implemented the Life & Active Cultures (LAC) seal, found on the product container.
3.Calcium
Dairy products are one of the best dietary sources of calcium in terms of bioavailability.
Calcium is essential for the development and maintenance of healthy bones and teeth. It is also important for blood clotting, wound healing, and maintaining normal blood pressure.
Calcium-rich foods are best when paired with a source of vitamin D, as vitamin D helps the small intestine to absorb calcium.
Most yogurts also contain varying amounts of vitamins B6 and B12, riboflavin, potassium, and magnesium
