Milk is an important source of essential nutrients. For children and teenagers, milk is an important part of a balanced diet. For adults, milk is a good source of protein, calcium and vitamins. Cow’s and buffalo’s milk are widely consumed in India, as a beverage and in various foods like flavored milk and milkshakes. Milk and milk products are convenient and easy way to include nutrients in daily diet.

Milk consists of water, fat and other solids. The other solids contain many essential nutrients. One cup of whole cow’s milk (approximately 240 ml) contains approximately 149 calories, 7.7 g of protein and 11.7 g of carbohydrates, and several essential minerals and vitamins. Milk is a good source of essential nutrients for growing children, and can be included in school lunch. One must consider that milk is not a balanced meal, and should not be a complete replacement of various foods in a diet.

Essential Nutrients in Milk and Their Health Benefits

Milk and other dairy products are important in our daily diet, and the health benefits of consuming dairy products are well documented.

1. Protein

Almost all of the protein in milk is made of casein (about 80%) and whey (about 20%). Both proteins help with the growth and repair of cells and tissue in the body. Casein is digested slowly, and whey is digested fast. Both help maintain and recover muscles and help normal development. So, including milk in your diet as an adult, child, or teen is beneficial.

2. Calcium

During the growth and development of kids and teenagers, it is important that they get enough calcium to get and maintain strong bones and teeth. As an adult, it is still important to get enough calcium to maintain the bones and teeth. Milk and other dairy products help get enough calcium, as well as other fortified plant-based drinks and foods, tofu made with the help of calcium, and certain leafy greens.

3. Phosphorus

Phosphorus also helps maintain strong bones and teeth, like calcium. It also helps the body make energy and maintain cell structures. Along with calcium, milk is an excellent source of phosphorus. Getting enough phosphorus is important for normal growth and development of the body.

4. Potassium

Potassium helps maintain the balance of fluids in the body, helps in normal muscle contractions, and helps maintain normal blood pressure. Milk has potassium with other minerals. Including potassium rich foods in the diet helps in maintaining normal cardiovascular health and normal functions of nerves. Potassium rich foods apart from milk include bananas, beans, potatoes, other fruits and vegetables.

5. Magnesium

Magnesium helps in production of energy and helps in normal function of nerves and muscles and helps in regulation of blood glucose. It helps in bone health and normal protein synthesis. Some magnesium is present in milk, but in order to meet the daily needs of the body other foods such as whole grains, nuts, and legumes are to be included in the diet as well.

6. Vitamin A

Vitamin A helps in maintaining normal vision and immune functions, and in cell growth and differentiation. It helps in normal reproductive functions and in the development of bones and teeth. The amount of vitamin A in milk varies with the fat content of milk and its processing and fortification. Other sources of Vitamin A are eggs and dark green and orange vegetables.

7. Vitamin D

Vitamin D helps in absorption of calcium and maintenance of normal bones and normal functions of muscles and nerves. It also helps in normal immune functions. Most milks do not have a lot of natural Vitamin D, so consumers should check the labels to see if a particular product is fortified with Vitamin D.

8. Vitamin B12

Vitamin B12 is important for the formation of blood and for the synthesis of DNA and the functioning of the nervous system. People who have a regular intake of dairy products can get their vitamin B12 from these foods. People following a strictly vegetarian diet may require fortified foods or supplements to meet their requirement.

9. Vitamin B2

Vitamin B2 is important for the conversion of food nutrients to energy and for normal functioning of the cells, as well as for the maintenance of the skin and eyes. Milk is one of the food sources of this vitamin and so, other dairy products can be of use to people wanting to include more riboflavin in their diets.

10. Vitamin B3

Niacin is important for the conversion of fats, carbohydrates and proteins to produce energy, and for normal functioning of the nervous system and skin. Milk and other dairy products have small amounts of niacin. Poultry, fish and whole grains are other food sources.

GMI Research expects the India Milk-Based Beverages Market to reach an incremental revenue of USD 3.5 billion by 2031. This report outlines a trend involving milk-based beverages and the opportunities it presents for producers to diversify their product offerings in response to the shift in consumer preference for convenience when it comes to dairy products.

The role of milk in nutrition is undeniable. Milk and milk based products can help consumers get a variety of essential nutrients, but the benefits depend on the milk product and an individual’s nutritional needs. Making informed decisions about the milk products one purchases and consuming them based on the overall dietary goals in conjunction with the product’s added and fortified nutrients can help consumers make a more informed choice.
