Milk is rich in nutrients, more and more people drink milk every day, but there are many studies have found that men who often drink milk are prone to prostate cancer. Prostate cancer is a common malignant tumor of the male reproductive system, the United States, Boston, a research team of 20,885 cases of American male physicians for up to 11 years of follow-up surveys, the consumption of dairy products, including skim milk, whole milk and cheese, etc., of which there are 1,012 cases of men with prostate cancer. Statistical analysis revealed that men who consumed 600 mg of calcium per day had significantly lower plasma concentrations of 1,25-dihydroxyvitamin D3 (which has antiprostate cancer effects) and a 32% increased risk of prostate cancer compared to men who consumed 150 mg of calcium per day from dairy products. After excluding age, weight, smoking, physical activity and other influences, it was found that men who ate more than 2.5 servings of dairy products per day (each serving is equivalent to 240 ml of milk) had a 34% increase in the risk of prostate cancer compared to those who ate less than 0.5 servings of dairy products. Researchers in Philadelphia, the United States, through nearly 10 years of epidemiological investigations have also confirmed that eating more dairy products will increase the risk of prostate cancer in men. Domestic studies have also found a significant correlation between milk intake and prostate cancer incidence, which may be attributed to the higher estrogen content of certain brands of milk. Thankfully, some plant compounds in fruits and vegetables have some anti-cancer properties. Lycopene is an important carotenoid that is widely found in fruits and vegetables. Tomatoes, apricots, guava, watermelon, papaya and red grapes all contain high levels of lycopene, especially in tomatoes. U.S. researchers of 46,000 cases of men conducted a six-year follow-up survey, found that there are 773 cases of prostate cancer; the study found that, compared with people who do not eat raw tomatoes, eat 2-4 times a week of raw tomatoes to reduce the risk of prostate cancer by 26%, tomato pizza and tomato sauce also have such a role; direct consumption of lycopene can also reduce the incidence of The risk of prostate cancer is also reduced by direct consumption of lycopene. The antioxidant property of lycopene is the strongest among the natural carotenoids, which has the effect of protecting the genetic material DNA (deoxyribonucleic acid), inhibiting the proliferation of cancer cells and regulating the hormone status, etc., and its anti-prostate cancer effect has been confirmed by a large number of researches. So, for the love of the prostate, men drink milk or have to take it easy, don't take it as a drink, in addition, pay special attention to nutritional balance, may want to eat more tomatoes every day.

Milk does not need to be boiled

Usually, the temperature requirement for milk sterilization is not high, 70 ℃ with 3 minutes, 60 ℃ with 6 minutes can be. If boiled, the temperature reaches 100 ℃, the lactose in milk will be caramelized, and caramel can induce cancer. Secondly, after boiling the calcium in milk will appear phosphate precipitation phenomenon, thus reducing the nutritional value of milk.

Don't add sugar when cooking milk

Some people cook milk, in order to make the sugar fast, often milk and sugar together, this is not scientific. Because the milk lysine and fructose at high temperatures, will generate a toxic substance -- fructosyl lysine. This substance can not be digested and absorbed by the body, will be harmful to the human body. If you want to drink sweet milk, it is best to wait for the milk to boil before putting sugar.

Milk is not the thicker the better

Some people believe that the thicker the milk, the more nutrients the body gets, which is not scientific.

The so-called too thick milk, refers to more milk powder in the milk less water, so that the concentration of milk beyond the normal proportion of standards. Some people are afraid that fresh milk is too light, they add milk powder in it. If infants and young children often eat too thick milk, will cause diarrhea, constipation, loss of appetite, or even refuse to eat, but also cause acute hemorrhagic enteritis. This is because infants and young children's organs are delicate, can not afford the excessive burden and pressure.

Milk in the calcium powder

Milk proteins, mainly casein, lactalbumin and lactoglobulin, and casein content is the most, accounting for 83% of the milk protein, and casein is composed of OCK-, K-, β- and γ-casein. If you drink milk, add calcium powder, too much calcium ions, will be combined with OCK- and β-casein, so that the milk coagulation phenomenon. In addition, calcium will also be combined with other proteins in milk to produce precipitation, especially when heated,

This phenomenon is more obvious. Therefore, to the pediatric calcium supplement, do not add calcium powder in milk.

Just use milk to serve drugs

Milk and its dairy products, contain a lot of calcium, iron and other ions, generally per liter of fresh milk, containing calcium 1300 mg, iron 0.4 mg. These ions and some drugs (such as tetracyclines, etc.) can generate stable complexes or insoluble salts, so that the drug is difficult to be absorbed by the gastrointestinal tract, and some drugs are even destroyed by these ions. If these drugs are served with milk, the concentration of the drug in the blood will be greatly reduced, affecting the therapeutic effect. Therefore, medicines should not be served with milk. Consumption of milk and its products should be 1 1/2 hours apart from the time of taking the medicine is appropriate.

Summer avoid drinking cold milk

In the hot summer, many people covet the convenience and cool, like to drink cold milk, in fact, is harmful. Milk is rich in nutrients, the protein contained in casein-based, followed by lactalbumin and lactoglobulin. Because of the high temperature in summer, milk is a good culture base for bacteria, boiling milk after cooling down for a few hours, it will be contaminated by bacteria and breeding, easy to cause intestinal diseases after drinking. Therefore, it is not advisable to drink cold milk in summer, or drink hot milk is good. Because, hot milk is not only killed bacteria, and milk protein denaturation, more conducive to human digestion and absorption.

Oranges and milk - about an hour before and after drinking milk, should not eat oranges

Because once the protein in the milk meets the fruit acid in the oranges, coagulation occurs, thus affecting the digestion and absorption of milk, and should not be eaten in this period of time, other acidic fruits.

Milk and chocolate

The two reactions affect the absorption of calcium in milk

Milk is rich in protein and calcium, while the chocolate contains oxalic acid, the two with food will be combined into insoluble calcium oxalate, greatly affecting the absorption of calcium. It can even lead to dry hair, diarrhea, and slow growth.

Drinking milk on an empty stomach

Milk contains a lot of protein, drinking on an empty stomach, the protein will be "forced" to be converted into calories to consume, and can not play a role in nutritional supplementation. The best way to drink is to eat with food containing flour, or drink two hours after meals, or drink before going to bed can be both nourishing health care, promote digestion, but also has the role of gas laxative.

It is not advisable to add orange juice or lemon juice in milk to increase the flavor

In the milk with a little orange juice or lemon juice, it looks like a good way to go, but in fact, the orange juice and lemon are high fruit acid fruits, and the fruit acid meets the protein in the milk, will make the protein denaturation, which reduces the nutritional value of the protein.

It is not advisable to add rice soup, rice in milk

Some people believe that this can make the nutritional complement. In fact, this practice is very unscientific. The milk contains vitamin A, while the rice soup and rice is mainly based on starch, they contain fat oxidation enzyme, will destroy vitamin A. Children, especially infants, if the intake of vitamin A is insufficient, it will make the infants stunted development, weak and sick. Therefore, even for supplemental nutrition, the two should be consumed separately.

Can't put bottled milk in the sun

Some people learn from advertisements: supplemental calcium and vitamin D, and more sunshine is a good way to get vitamin D, so they will follow the prescription to put bottled milk in the sun. In fact, this does not pay off. Milk may get some vitamin D, but lost vitamin B1, vitamin B2 and vitamin C. Because these three nutrients will be decomposed in the sun, so that part or all of them are lost; and, in the sun lactose will be fermented, so that the milk spoiled.

Condensed milk can not replace milk

Condensed milk is a milk product, is the fresh milk evaporated to the original capacity of 2 / 5, and then add 40% of the cane sugar canned. Some people are influenced by the idea that "whatever is concentrated is the essence" and use condensed milk instead of cow's milk. This is obviously wrong. Condensed milk is too sweet and must be diluted with 5-8 times water. However, when the sweetness meets the requirements, the concentration of protein and fat is often reduced by half compared to fresh milk. If you add water to condensed milk, so that the concentration of protein and fat close to fresh milk, then the sugar content will be high again.
