Dairy is very nutritious and provides a lot of calcium and protein. Some of the most popular dairy products include cream, butter, yogurt, cheese, and milk. However, it is important to know that around 75% of people cannot break down lactose, which is the type of sugar in milk. This issue is called lactose intolerance. People with this condition might experience many digestive issues, such as diarrhea, cramping, gas, as well as bloating. Thus, you should go for lactose-free milk and dairy products. Also, consume some safer alternatives such as rice, soy, almond, and coconut milk.
