Nutritional value, benefits and side effects


Children drinking milk

Milk is a highly nutritious liquid produced by the mammary glands of animals to support infants during the first months of life. Milk is used to make a wide range of food products, including cheese, cream, butter and yogurt.

These foods are called dairy products or dairy products and they are an important part of the modern diet.

Nutritional contributions:

The nutritional composition of milk is very complicated and it contains almost all the nutrients that your body needs.

One cup (240 ml) of whole cow’s milk with 3.25 percent fat provides:

• Calories: 149

• Water: 88%

• Protein: 7.7 grams

• Carbohydrates: 11.7 grams

• Sugar: 12.3 grams

• Fiber: 0 grams

• Fat: 8 grams

Vitamins & Minerals

Milk provides all the vitamins and minerals necessary for the growth and development of a baby calf throughout its first months of life. It also contains almost all of the vitamins needed by humans, making it one of the most nutritious meals available.

Milk contains particularly high levels of the following vitamins and minerals:

• Vitamin B12: This essential vitamin is only found in foods of animal origin. Milk contains a lot of B12.

• Calcium: Milk is not only one of the greatest sources of calcium in the diet, but calcium in milk is also easily absorbed.

• Riboflavin: In the Western diet, dairy products are the most important source of riboflavin, commonly known as vitamin B2.

• Phosphorus: Dairy products are rich in phosphorus, a mineral necessary for many biological processes.

Often enriched with vitamin D

The technique of adding minerals or vitamins to foods is known as fortification. As a public health strategy, fortification of dairy products with vitamin D is widespread and mandatory in some countries.

In the United States, 1 cup (240 ml) of milk fortified with vitamin D can contain up to 65% of the recommended daily allowance for this nutrient.

Milk is one of the most nutrient dense foods available. It has been the subject of a lot of research and appears to offer a number of important health benefits. Cow’s milk, in particular, can be beneficial for your bones and blood pressure.

Osteoporosis and bone health

The most common risk factor for bone fractures in older people is osteoporosis, a disease defined by a decrease in bone density. Cow’s milk promotes the growth and development of bones in newborn calves, which is one of its roles.

Cow’s milk appears to have similar benefits in humans and has been linked to increased bone density. The high calcium and protein content of milk is believed to be the main factors in this effect.

Arterial pressure

Abnormally high blood pressure is a major risk factor for heart disease. Dairy products have been linked to a lower risk of high blood pressure. This effect is believed to be caused by the unique blend of calcium, potassium and magnesium in milk. Other factors, such as the peptides produced during the digestion of casein, could also play a role.

Helps prevent weight gain

A study of 145 three-year-old Latino children found that consuming more milk fat was linked to a lower risk of childhood obesity.

Another study, involving more than 18,000 middle-aged and older women, found that consuming higher-fat dairy products was linked to less weight gain and lower risk of obesity.
Milk contains a number of nutrients that can help with weight loss and prevent weight gain. For example, its high protein level keeps you feeling fuller for longer, which can help you avoid overeating.

Additionally, conjugated linoleic acid in milk has been tested for its potential to promote fat breakdown while preventing fat formation.

Possible negative effects

The health effects of milk are complicated; some components of milk are extremely useful, while others can have negative effects.

Lactose intolerance

Lactose, often called milk sugar, is the main carbohydrate found in milk. In your digestive tract, it is broken down into its components, glucose and galactose. Lactose intolerance occurs when some people lose their ability to properly digest lactose after childhood.

Lactose intolerance affects around 75% of the world’s population. However, the number of people who are lactose intolerant varies widely depending on genetic makeup.

Lactose is not fully absorbed in people who are lactose intolerant, and some or most of it travels to the colon, where the resident bacteria begin to digest it. This fermentation process produces short chain fatty acids (SCFAs) and gases such as methane and carbon dioxide.

Lactose intolerance causes a variety of unpleasant symptoms such as gas, bloating, stomach cramps, diarrhea, nausea, and vomiting.

Cancer and milk

Numerous observational studies have been conducted to investigate the link between milk and cancer risk. Overall, the evidence is ambiguous and few conclusions can be drawn from it. Several studies, however, suggest that consuming dairy products may increase the risk of prostate cancer in men.
Many studies, on the other hand, have established a relationship between the consumption of dairy products and a decreased risk of colon cancer.


Acne – a common skin disorder marked by pimples, especially on the face, chest, and back – has been linked to drinking milk.

High milk consumption is known to increase levels of insulin-like growth factor-1 (IGF-1), a hormone believed to be involved in the development of acne.
