The Importance of Milk in the Diet
Milk products contain high quality proteins. The whey proteins constitute about 18 percent of the protein content of milk. Casein, a protein found only in milk, contains all of the essential amino acids. It accounts for 82 percent of the total proteins in milk and is used as a standard for evaluating protein of other foods. Protein is needed to build and repair body tissues and to form antibodies which circulate in the blood and help fight infection.
Milk contains nutrients such as: calcium, phosphorus, magnesium, and potassium. The calcium found in milk is readily absorbed by the body. Phosphorus plays a role in calcium absorption and utilization. Phosphorus is needed in the proper ratio to calcium to form bone. Milk provides these two minerals in approximately the same ratio as found in bone. Milk is also a significant source of riboflavin (vitamin B2) which helps promote healthy skin and eyes as well as vitamins A and D.
In adults, a calcium deficiency, along with other factors, may result in bone deterioration called osteoporosis.
The following daily consumption of milk is suggested:
|Adults over 51||4 cups|
|Pregnant and lactating woman||3 cups|
There are two types of osteoporosis: primary osteoporosis and secondary osteoporosis. Primary osteoporosis is most common. It is usually related to age in which the older you get, the more bone loss you are likely to have, especially if you don’t take in enough calcium.
Secondary osteoporosis is caused by diseases or other factors that affect the body and cause bone loss, such as:
- hormone problems, like hyperthyroidism (say: hi-per-thi-royd-is-em), which is an overactive thyroid gland
- eating disorders, like anorexia nervosa – taking high doses of the drug steroids for a long time
- too much smoking or drinking
