Milk is a natural food source for mammals. Animals, including humans, produce milk to feed their young until they are ready for solid food. As such, milk contains valuable nutrients that help support a growing body, including calcium and protein. Research about milk is conflicting, however, with different studies claiming milk is either good or bad for the body.

Due to rising concerns about health, lactose intolerance, and animal welfare, plant-based milkand dairy alternatives are gaining popularity. Official sources, such as the Dietary Guidelines for Americans —recommend that adults eat about 3 cup-equivalent of low fat or fat-free dairy each day as part of a healthful diet. Calcium is an essential nutrient for strong bones and teeth, muscle movement, and nerve signals.

Health authorities recommend getting enough calcium to help prevent bone fractures and osteoporosis. Milk offers a rich source of calcium. While calcium is important, not all studies agree that milk is good for preventing osteoporosis or fractures, as a review discusses. Due to this discrepancy, scientists still need to do more research.

Milk is a source of potassium, which can help the blood vessels dilate and reduce blood pressure. Getting more potassium while also reducing sodium salt intake can lower blood pressure, reducing the risk of heart disease and stroke.

Many people in the U. Calcium may protect the gut lining to reduce the risk of colon cancer or rectum cancer.

However, research has linked too much calcium with prostate cancer. Vitamin D might play a role in cell growth regulation. It may help protect against colon cancer, and possibly prostate and breast cancer.

However, research has also linked high vitamin D levels to an increased risk of pancreatic cancer. Many factors affect cancer risk. Likewise, cancer can take a long time to develop, so it is difficult to study its causes and risk factors. Adequate vitamin D levels support the production of serotonina hormone people associate with mood, appetite, and sleep. Research, including a reviewhas linked vitamin D deficiency with clinical depression.The closer a food is to the right edge of the map, the more essential nutrients per calorie it contains.

For a more nutritious diet, select foods that fall on the right half of the map. The closer a food is to the top edge of the map, the more likely it is to fill you up with fewer calories. If you want to restrict your caloric intake without feeling hungry, choose foods from the top half of the map.

Foods that are close to the bottom edge are more calorie-dense. If you want to increase your calorie intake without getting too full, choose foods from the bottom half of the map.

The spoke for dietary fiber is colored green, protein is blue, vitamins are purple, minerals are white, and yellow represents a group of commonly overconsumed nutrients: saturated fat, cholesterol, and sodium.

A Completeness Score between 0 and is a relative indication of how complete the food is with respect to these nutrients.

Although few if any individual foods provide all the essential nutrients, the Nutrient Balance Indicator and Completeness Score can help you construct meals that are nutritionally balanced and complete. Read more about the Nutrient Balance Indicator.

If one or more amino acid is not present in sufficient amounts, the protein in your diet is considered incomplete. Each spoke on the Protein Quality graph represents one of the nine essential amino acids, and the graph shows how close the protein in your diet is to the optimal distribution of amino acids recommended by the Institute of Medicine's Food and Nutrition Board.

An Amino Acid Score of or higher indicates a complete or high-quality protein. If the Amino Acid Score is less thana link is provided to complementary sources of protein. By combining complementary proteins, you may be able to increase the overall quality of the protein you consume. Read more about Protein Quality.

Nearly all infants who develop an allergy to milk do so in their first year of life.

Symptoms of a milk allergy reaction can range from mild, such as hives, to severe, such as anaphylaxis. Epinephrine is the first-line treatment for anaphylaxis. Always read food labels and ask questions about ingredients before eating a food that you have not prepared yourself.

For example, goat's milk protein is similar to cow's milk protein and may cause a reaction in people who have a milk allergy. Milk is one of the eight major allergens that must be listed on packaged foods sold in the U.

Avoid these products if you have a milk allergy. However, a product may be considered pareve even if it contains a very small amount of milk protein—possibly enough to cause an allergic reaction in certain people. Do not assume that these products will always be safe. People allergic to milk often have questions about the following ingredients. These ingredients do not contain milk protein and are safe to eat.

Most children eventually outgrow a milk allergy. Blood tests that measure these antibodies can help your allergist determine whether or not a child is likely to outgrow a milk allergy.

It contains everything that a human baby's body needs to grow, develop, mature, and survive. It's not only a complete source of nutrition, but it also helps to protect children from disease and illness as they grow.

As scientists study breast milk, they have discovered so far that it contains over different ingredients so far. Without a complete analysis and a real understanding of what each element in breast milk does, it makes it very hard for the manufacturers of infant formula to try to copy its composition.

Even though infant formula is a safe, acceptable alternative to breast milk, it's not equal. It's just not possible to recreate the makeup and ever-changing status of breast milk. Of the many components that we currently know about in breast milk, a few stand out. We're familiar with water, carbohydrates, lipids, and proteins, but let's explore how these factor into the nutritional value of your breast milk and how they help your baby grow and develop.

The human body needs water for almost everything it does.

Carbohydrates are the body's number one source of energy. The main carbohydrate in your breast milk is the milk sugar known as lactose. Compared to cow's milk, there is much more lactose in human milk. Other carbohydrates found in breast milk such as oligosaccharides are needed to promote healthy bacteria in the intestines.

Lipids are a major source of energy, cholesterol, and essential fatty acids such as DHA. They are necessary for the development of your baby's brain, nervous system, and vision. Lipids are also responsible for your baby's weight gain as he grows.

Your breast milk should contain all the lipids that your little one needs. They are also needed to make hormones, enzymes, and antibodies. The protein in your breast milk is very easy for your baby to digest and your child needs protein to grow and develop. One very important protein in breast milk is lactoferrin. Lactoferrin moves iron through your baby's body, but it also helps to protect your newborn's intestines from infections.

Immunoglobulins are antibodies that fight off the germs that cause illness and disease. Your breast milk is like your baby's first vaccine. It contains antibodies that fight off bacteria, viruses, fungus, and parasites. The immune properties found in breast milk can also help protect your child from the common cold, ear infections, vomiting, diarrhea, and other dangerous infections that affect newborns and infants.Powdered milk or dried milk is a manufactured dairy product made by evaporating milk to dryness.

One purpose of drying milk is to preserve it; milk powder has a far longer shelf life than liquid milk and does not need to be refrigerateddue to its low moisture content. Another purpose is to reduce its bulk for economy of transportation. Powdered milk and dairy products include such items as dry whole milk, nonfat skimmed dry milk, dry buttermilk, dry whey products and dry dairy blends. Many dairy products exported conform to standards laid out in Codex Alimentarius.

Many forms of milk powder are traded on exchanges. Powdered milk is used for food and health nutritionand also in biotechnology [1] saturating agent [ clarification needed ]. While Marco Polo wrote of Mongolian Tatar troops in the time of Kublai Khan who carried sun-dried skimmed milk as "a kind of paste", [2] the first modern production process for dried milk was invented by the Russian doctor Osip Krichevsky in Dirchoff in InT.

Grimwade took a patent on a dried milk procedure, [4] though a William Newton had patented a vacuum drying process as early as In modern times, powdered milk is usually made by spray drying [6] nonfat skimmed milkwhole milk, buttermilk or whey. Pasteurized milk is first concentrated in an evaporator to approximately 50 percent milk solids.

The resulting concentrated milk is then sprayed into a heated chamber where the water almost instantly evaporates, leaving fine particles of powdered milk solids. Alternatively, the milk can be dried by drum drying.

Milk is applied as a thin film to the surface of a heated drum, and the dried milk solids are then scraped off. However, powdered milk made this way tends to have a cooked flavour, due to caramelization caused by greater heat exposure. Another process is freeze dryingwhich preserves many nutrients in milk, compared to drum drying.

The drying method and the heat treatment of the milk as it is processed alters the properties of the milk powder, such as its solubility in cold water, its flavour, and its bulk density. Powdered milk is frequently used in the manufacture of infant formulaconfectionery such as chocolate and caramel candyand in recipes for baked goods where adding liquid milk would render the product too thin.

Powdered milk is also widely used in various sweets such as the famous Indian milk balls known as gulab jamun and a popular Indian sweet delicacy sprinkled with desiccated coconut known as chum chum made with skim milk powder. Many no-cook recipes that use nut butters use powdered milk to prevent the nut butter from turning liquid by absorbing the oil. Powdered milk is also a common item in UN food aid supplies, fallout shelterswarehouses, and wherever fresh milk is not a viable option.

It is widely used in many developing countries because of reduced transport and storage costs reduced bulk and weight, no refrigerated vehicles.

Like other dry foods, it is considered nonperishable, and is favored by survivalistshikersand others requiring nonperishable, easy-to-prepare food. Because of its resemblance to cocaine and other drugs, powdered milk is sometimes used in filmmaking as a non-toxic prop that may be insufflated. Milk powders contain all 21 standard amino acidsthe building blocks of proteinsand are high in soluble vitamins and minerals. In Canadapowdered milk must contain added vitamin D in an amount such that a reasonable daily intake of the milk will provide between and International Units IU of vitamin D.

Some free radicals-derived oxysterols have been suspected of being initiators of atherosclerotic plaques. European production of milk powder is estimated aroundtons of which the main volume is exported in bulk packing or consumer packs. In the Chinese milk scandalmelamine adulterant was found in Sanlu infant formulaadded to fool tests into reporting higher protein content. Thousands became ill, and some children died, after consuming the product. In AugustChina temporarily suspended all milk powder imports from New Zealand, after a scare where botulism-causing bacteria was falsely detected in several batches of New Zealand-produced whey protein concentrate.

As a result of the product recall, the New Zealand dollar slipped significantly [ quantify ] based on expected losses in sales from this single commodity.

Fat-free powdered milk is used as a saturating agent to block nonspecific binding sites on supports like blotting membranes nitrocellulosepolyvinylidene fluoride PVDF or nylon[17] preventing binding of further detection reagents and subsequent background.

The major protein of milk, caseinis responsible for most of the binding site saturation effect. From Wikipedia, the free encyclopedia.A description of the nutritional function of vitamins and minerals is provided on the Nutritional Components in Milk page in the Nutrition Facts section. For more details on the vitamins and minerals in milk, see references by Flynn et al. Vitamins have many roles in the body, including metabolism co-factors, oxygen transport and antioxidants. They help the body use carbohydrates, protein, and fat.

The specific content of vitamins in milk is listed in the Nutrient Content Tables in the Nutrition Facts section. Milk contains the water soluble vitamins thiamin vitamin B1riboflavin vitamin B2niacin vitamin B3pantothenic acid vitamin B5vitamin B6 pyridoxinevitamin B12 cobalaminvitamin C, and folate.

Milk is a good source of thiamin, riboflavin and vitamin B Milk contains small amounts of niacin, pantothenic acid, vitamin B6, vitamin C, and folate and is not considered a major source of these vitamins in the diet. Milk contains the fat soluble vitamins A, D, E, and K. The content level of fat soluble vitamins in dairy products depends on the fat content of the product.

Fortification of all milk with vitamin D is voluntary. Milk contains small amounts of vitamins E and K and is not considered a major source of these vitamins in the diet. Minerals have many roles in the body including enzyme functions, bone formation, water balance maintenance, and oxygen transport.

The specific content of minerals in milk is listed in the Nutrient Content Tables in the Nutrition Facts section. Milk is a good source of calcium, magnesium, phosphorus, potassium, selenium, and zinc. Many minerals in milk are associated together in the form of salts, such as calcium phosphate. The fact that calcium and phosphate are associated as salts bound with the protein does not affect the nutritional availability of either calcium or phosphate.

Milk contains small amounts of copper, iron, manganese, and sodium and is not considered a major source of these minerals in the diet. The mild heat treatment used in the typical high temperature short time HTST pasteurization of fluid milk does not appreciably affect the vitamin content. However, the higher heat treatment used in ultra high temperature UHT pasteurization for extended shelf combined with the increased storage life of these products does cause losses of some water-soluble vitamins.

Thiamin is reduced from 0. Riboflavin is a heat stable vitamin and is not affected by severe heat treatments. Calcium phosphate will migrate in and out of the casein micelle with changes in temperature. This process is reversible at moderate temperatures. This does not affect the nutritional properties of milk minerals. At very high temperatures the calcium phosphate may precipitate out of solution which causes irreversible changes in the casein micelle structure.

Exposure to light will decrease the riboflavin and vitamin A content in milk. Milk should be stored in containers that provide barriers to light opaque plastic or paperboard to maximize vitamin retention.

Vitamins in Milk Vitamins have many roles in the body, including metabolism co-factors, oxygen transport and antioxidants.
