Bone health is often associated with drinking milk, given the calcium content in it which is considered to have a big role for bones. Many people regularly drink milk to maintain bone health in the present and prevent bone damage in old age. However, further research actually shows that milk consumption does not always have a good effect on human bones. In fact, it turns out that drinking too much milk can increase the rate at which calcium is reduced in bones, you know!
Is milk really can maintain bone health, or is this just a myth created by milk producers, huh?

Why is milk called good for bone health?
Milk is a drink that contains complete nutritional components, ranging from carbohydrates, fats, proteins, vitamins, to various types of biological enzymes. The content of various nutrients in milk is what supports the functions and benefits of milk, ranging from energy sources to carry out daily activities to helping oxygen transport in the body.
One of the ingredients in milk that is best known to the public is calcium, a type of mineral that has an important role in bone formation, muscle contraction, nerve transmission, and blood clotting. Apart from calcium, milk also contains magnesium which has an important role in bone metabolism and manganese which plays a role in bone formation. Not infrequently, milk is given the title as a drink that is "friendly" to bone health.
Dairy products and their derivatives (dairy products) does contain enough calcium to meet the calcium needs of the body, where one glass of cow's milk can meet 30 percent of daily calcium needs. Compared to other foods, milk is a source of calcium that has the highest calcium concentration per serving. These calcium are 99 percent stored in teeth and bones, while the rest can be found in the blood and other tissues.
Therefore, many people believe that consumption of milk and its derivative products will prevent osteoporosis and decreased bone health because it can meet the calcium needs of the bones and help solidify bone mass.

Drinking too much milk increases the risk of fractures
Previous studies have shown that the calcium in milk can help strengthen bones and prevent osteoporosis - which can lead to the risk of fractures. However, recent studies have shown that drinking too much milk does not help prevent bone fractures.

Women who drink too much milk actually have a higher risk of fractures than other women who consume small amounts of milk. The risk of fracture increased by 16 percent in women who drank 3 or more glasses of milk per day, and the risk of fractures in the waist increased by 60 percent.
Various research evidence on the effect of milk on bones
Other studies related to milk and bone health:
- Research from Harvard shows that individuals who drink only one glass of milk a week, or don't even drink milk at all, have the same risk of fractures as people who drink more than two glasses of milk each week.
- A two-decade Harvard study of 72,000 women shows that there is no evidence that milk consumption prevents fractures or osteoporosis.
- Another study that followed more than 96,000 people showed that the more milk a person consumes, the more likely it is that bone fractures will occur as an adult.
- Reporting from American Journal of Epidemiology , Cumming and Klineberg announced that consumption of milk, especially at age 20 years, is actually associated with an increased risk of hip fracture (hip fracture) in old age ("Case-Control Study of Risk Factors for Hip Fractures in the Elderly". American Journal of Epidemiology. Vol. 139, No. 5, 1994).
Our bodies have difficulty absorbing calcium from milk
Many studies have shown that many of the detrimental health effects come from consuming milk. The surprising thing is, it turns out that the body actually has difficulty absorbing the calcium contained in cow's milk, especially pasteurized cow's milk. Then, it turns out that milk increases the rate of reduction of calcium in the bones.
Milk is a food that causes the body's pH to decrease (becomes more acidic) after it is metabolized by the body, so the body must neutralize the body's pH to reach a neutral state by adding alkaline or alkaline substances in the body. This neutralizing process uses calcium which is alkaline. Ironically, calcium, which is much stored in the bones, is also used to neutralize the effects of acidification caused by the body's metabolism. When calcium is released from the bones, it is excreted by the body through urine, which causes calcium deficiency in the body.
