Milk is a basic part of our daily diet, but did you know that it has some surprising health benefits? In this video, we’ll take a look at why milk is good for us and what else you should know before buying dairy products.

Milk contains calcium, vitamin D, potassium, protein, phosphorus, riboflavin, zinc, magnesium, sodium, copper, iodine, selenium, niacin, pantothenic acid, and iron. These nutrients play important roles in maintaining bone health, muscle function, nerve transmission, energy production, and immune system function.

Adults who don’t drink enough milk or eat too much processed food may experience symptoms such as gas, bloating, stomach pain, diarrhea, constipation, and fatigue.
