Coffee basic knowledge Coffee how to drink the healthiest?

What should I do to maximize the health benefits of coffee? How many cups of coffee can you drink at most every day? BELMOCA Barmoka introduces to you what you must know about healthy coffee drinking!

For thousands of years, coffee has been one of the two or three most popular drinks on earth. But it is not until recently that scientists have gradually discovered that the drink has remarkable health benefits. In a large-scale epidemiological study published last year, researchers, mainly from the National Cancer Institute (National Cancer Institute), analyzed the health information of more than 400,000 volunteers between the ages of 50 and 71 who were not seriously ill at the start of the study in 1995. By 2008, more than 50,000 of them had died. But men who claimed to drink two or three cups of coffee a day had a 10 per cent lower risk of death than men who did not drink coffee at all, while women who drank the same amount of coffee had a 13 per cent lower risk of death during the study period. The researchers did not know exactly what effect coffee had on the longevity of the respondents, but the association was striking.

Other recent studies have found that moderate consumption of coffee-three or four cups of coffee a day of five ounces each, or an extra large cup of coffee from Starbucks-can bring more definite benefits: reducing the risk of recurrence of type 2 diabetes, basal cell cancer (the most common skin cancer), prostate, oral and breast cancer.

All right, Primary one won't say much, let's get to the point!

When is the best time to have coffee?

When people feel tired from exercise or mental work, adenosine is gradually hoarded in the brain as a product of energy metabolism, making people feel tired. If you drink coffee at this time, then caffeine will replace adenosine in the brain attached to the adenosine receptor, so that people do not feel tired, thus preventing drowsiness. If you drink coffee during a nap, you can get a good state of mind after 20-30 minutes. The human body secretes melatonin to resist aging factor reactive oxygen species when sleeping at night, and can resist it by polyphenols in coffee during the day to achieve the anti-aging effect. But it should be noted that caffeine stimulates excessive secretion of stomach acid, so people with too much stomach acid should drink less coffee and be more careful not to drink coffee on an empty stomach.

Add some milk to make caffeine absorption more stable

Coffee drinkers often like the bitter and sour taste of coffee, but black coffee gives people some headaches. At this time, milk and sugar can be put in to improve the taste without affecting the health properties.

Professionals point out that the addition of sugar or milk to coffee will not affect the absorption of polyphenols, and a spoonful of coffee with about 5 grams of sugar basically will not affect blood sugar, nor will it hinder the fat-burning effect of coffee. However, if you put too much sugar can easily lead to excessive energy intake, you must pay attention to it. In addition, if a small amount of milk is added to the coffee, the body can absorb caffeine more slowly. The rapid absorption of caffeine is easy to stimulate excessive secretion of gastric acid, resulting in heartburn and other symptoms, so children or people with excessive stomach acid drink coffee, it is best to add a little milk.

You can't drink too much coffee. Pregnant women can actually drink it.

Due to the medical effect of caffeine, if the concentration of caffeine in the blood rises sharply, it may stimulate the central nervous system, causing dizziness, rapid heartbeat, excitement, restlessness and other mental symptoms. If the concentration of caffeine in the blood exceeds 40 micrograms / ml, no matter who may have arrhythmias, spasms and other symptoms. If you drink more than 10 cups in a row, other side effects may occur. As caffeine can remain in the human body for about 5 hours, so drink coffee should be careful not to drink continuously.

Can pregnant women drink coffee? Many people are very concerned about this problem. The British Financial Services Authority (FSA) said in a 2008 statement that pregnant women who eat too much caffeine can easily lead to fetal weight loss and increase future health risks, so pregnant women should not eat more than 200mg caffeine every day. For pregnant women, you can drink coffee, but the amount should be limited to 1-2 cups a day.

Drinking coffee will not cause chills.

In the survey of coffee polyphenol intake and skin condition in Japan, the relationship between coffee intake and body cold was also investigated. the results showed that there was no correlation between coffee consumption and body cold. In contrast, caffeine has a thermogenic effect, with 3-4 cups of coffee producing about 10% of calories. For people with low blood pressure and hypothermia, drinking a cup of coffee in the morning is a wise way to put a warm switch in the body, but it is best to drink hot coffee.
