Key Nutrients of Dairy

Milk and dairy products offer an excellent combination of all the main macronutrients, including carbohydrates, proteins and fats, in well-balanced proportions. They also provide a range of vitamins and important minerals that the body needs. Milk is best known for its calcium content, which supports key functions in the human body, most notably the development and maintenance of strong bones and teeth.

Proteins

Proteins are substances with a fundamental and essential role in life. Their very name reflects this importance. They are a vital component for every living organism. Proteins provide energy, support memory, aid recovery and help build stronger muscle tissue.

The human body obtains the proteins it needs through food. To ensure the intake of all essential amino acids, it is important to consume a variety of both plant and animal foods, as each source provides different types and amounts of amino acids. Depending on their origin, proteins are classified as either plant-based or animal-based.

The protein found in milk covers around 15 percent of the daily requirement and contributes to the repair of muscle tissue.

Carbohydrates (Lactose)

Milk is the only food in nature that contains the carbohydrate lactose (the natural sugar found in milk and dairy products). Lactose is broken down slowly in the body into glucose and galactose and is an important source of energy for the body.

For lactose found in milk and dairy products to be broken down and absorbed by the body, an enzyme called lactase is required. If the small intestine does not produce enough lactase, then it may mean that you suffer from lactose intolerance. Researchers estimate that up to 70% of the global population suffers from lactose intolerance.

For some people, lactose intolerance may prevent the consumption of milk or dairy products altogether, while others may still be able to consume small amounts selectively or choose dairy products that contain reduced or no lactose.

Vitamin B1 (Thiamine)

Thiamine, also known as vitamin B1, was first isolated from rice in 1926. Vitamin B1 belongs to the B-vitamin complex and contributes to energy production, heart health, the normal functioning of the nervous system and psychological wellbeing. It is found in foods such as bread, cereals, potatoes, milk, meat, peanuts, yeast, soy, etc.

Vitamin B2 (Riboflavin)

Riboflavin (vitamin B2) is a member of the B-vitamin complex. It was first isolated from milk whey in 1933 by Dr Kuhn. Vitamin B2 contributes to energy production, helps reduce fatigue, supports the normal functioning of the nervous system and plays a role in maintaining the health of the mucous membranes, skin and eyes. It is found in foods such as milk, meat, yeast, wheat germ, fortified cereals and eggs, among others.

Around 25% of riboflavin intake comes from milk, where it helps the body use carbohydrates, fats and proteins to produce energy.

Vitamin B12

Vitamin B12 is part of the B-vitamin complex and contributes to energy production, the reduction of fatigue, the normal functioning of the nervous system and overall psychological wellbeing. It is found in foods such as liver, beef, fish and eggs, etc.
Vitamin B12 is also required for the synthesis of DNA and therefore for the production of cells, particularly red blood cells. Milk provides around 10% of the Recommended Daily Intake of vitamin B12 and supports the normal function of the blood as well as the maintenance of a healthy nervous system.

Because it is found mainly in foods of animal origin, vitamin B12 is one of the nutrients that vegetarians and especially vegans often lack.

Calcium

Calcium is one of the most important minerals for the human body. It is essential for the health of bones, teeth and muscles and contributes to normal blood clotting. Vitamin D is necessary for its absorption. About 99% of the body's calcium is stored in the bones, while the remaining 1% is found in soft tissues. Calcium absorption depends to a significant extent on vitamin D, which means that a deficiency in vitamin D and a lack of calcium can produce similar symptoms.

Milk contains 30% of the Recommended Intake of calcium (RI) which helps in the structure and maintenance of strong bones and teeth. Milk and dairy products (cheese and yoghurt) are a rich source of calcium. The recommended daily calcium intake is difficult to achieve without consuming milk and dairy products.

Phosphorus

Around 25% of phosphorus intake comes from milk, where it helps support the development of skeletal tissue. Phosphorus is an important element with many essential biological functions in the human body. It is present in all tissues and body fluids and forms a key component of many biological compounds, including lipids, proteins and carbohydrates. Phosphorus is also a fundamental structural element of bones and teeth.

Iodine

Iodine is an essential mineral for the human body. Our body needs iodine and since it cannot produce it on its own, it must obtain it through food. It is necessary for the normal production of thyroid hormones and for the proper functioning of the thyroid gland. Iodine also supports the health of the nervous system and contributes to normal cognitive function. A deficiency can lead to hypothyroidism, while supplementation is often necessary for strict vegetarians and vegans.

Probiotics

Probiotics are beneficial microorganisms that have a positive effect on the human body. They take their name from their ability to convert sugars into lactic acid, creating an acidic environment that prevents the growth of harmful pathogens. Probiotics can support the healthy functioning of the digestive system and help reduce stomach-related issues by protecting the intestinal microflora. They may also help with digestive problems such as bloating, indigestion, constipation etc.
