Scientist: coffee can make you feel good and fight colds, but not too much.

Chinanews.com, Aug. 12-according to Russian media reports on August 10, it is strong, refreshing and fragrant. No other drink in the world has so many modifiers. Maybe that's why coffee is more popular and contradictory than all other drinks.

The benefits of coffee are as much written as its disadvantages. Is coffee our enemy or good friend? is it worth it or is it best not to touch it? The controversy about coffee is never-ending. It seems that scientists will continue to discuss this issue: if you don't believe me, take a look at the latest research results.

The embodiment of contradiction

Coffee is as good as chocolate in terms of pleasure. So, if life is not going well, don't eat sweets for comfort, but try a cup of coffee, which can reduce your calorie intake. But be aware that coffee without caffeine doesn't work!

Coffee should not be eaten with fatty foods. The amount of sugar in the blood increased significantly after eating fast food, and Mary Sorrell Baudouin of the University of Guelph in Canada found that a combination of caffeine and such fatty foods doubled the amount of glucose. This amount has reached the standard for people at high risk of diabetes.

After observing the health of 400000 people aged 51 to 70 for 12 years, scientists have concluded that three cups of coffee a day can increase the life expectancy of the elderly by 10%. The results show that regular consumption of aromatic drinks contributes to the physiology of the cardiovascular system, brain, respiratory tract and other organs. In addition, coffee lovers are less likely to suffer from trauma, diabetes and infectious diseases.

Coffee helps women in stressful situations, but the opposite is true for men. In the 100-second experiment, women who drank regular coffee completed brain teasers and memory tests faster than those who drank decaffeinated coffee. Men who drank regular coffee, however, took an extra 20 seconds to solve brain teasers and significantly worsened their information memory.

Coffee can be used to manipulate people. At a seminar on major social issues, scientists from Australian universities invited 140 volunteers. Half of them drank coffee during the discussion, while the other half drank tea or nothing. As a result, after drinking the second cup of coffee, the discussant began to abandon his point of view when he heard the other side's rebuttal evidence. Those who drink other drinks still stick to their point of view. Experts explain that large amounts of caffeine can cause euphoria. The combination of this feeling and adrenaline interferes with our concentration.

Anti-cold and cellulitis

Generally speaking, coffee not only has all the above-mentioned characteristics, but also can cure diseases! For example:

O Coffee can be used as a painkiller (mainly for women)

O as a cough medicine-it is recommended to cover a hot espresso with a towel and breathe the heat on it when you catch a cold.

O doctors believe that coffee lovers are significantly less likely to suffer from type 2 diabetes, Parkinson's disease, Alzheimer's disease, bowel cancer, liver cancer and gallbladder cancer. But doctors also say caffeine addiction is rapid (statistics show that caffeine addiction begins almost at the first cup of coffee). It is dangerous to eat too much coffee. Excess caffeine increases the risk of cardiovascular disease, accelerates osteoporosis in women (especially during menopause), and increases the excretion of calcium from the kidneys, which is the main culprit of stones.

Master the scale

No one knows exactly how many cups of coffee will change from an ally to an enemy. Doctors say sensitivity to caffeine varies from person to person. Some people may not even respond to two or three drinks, while others may not sleep all night after one drink. Also consider what kind of coffee you drink: between 0.8% and 1.5%, 2% for Arabica caffeine, and 1.5% to 2%, 3% for robusta caffeine. Of course, the concentration of coffee is also important. To avoid excessive caffeine, experts recommend eating bananas when drinking espresso. Excess caffeine can disrupt the body's potassium-calcium balance, causing muscle pain or convulsions. And bananas happen to be an excellent source of potassium. If you drink another glass of milk or eat a piece of cheese, then calcium levels will easily recover.

Here are some coffee drinking tips.

Coffee and food are not compatible. The two will destroy each other's flavor and characteristics. Coffee slows down the absorption of beneficial substances in food, especially iron. And its own pick-me-up effect will be greatly reduced.

Coffee can be used as a daytime snack, can also be used as medicine, can suppress 2-3 hours of appetite. You don't need sugar to drink coffee, it's OK to add milk.

Coffee should not be drunk in one go, as it will lose most of its performance. Drink coffee slowly with a small spoon to enjoy its delicious and unusual aroma. (Dong Mi)
