How to drink coffee in order to be healthy?

A friend asked: "I heard that drinking coffee is good for health?" And I said,"Yeah!" He said,"I drink it every day, how can I still have diabetes and high blood pressure?" I said,"What kind of coffee are you drinking?" "Instant three-in-one!" "F * ck!"

The so-called injustice has a head and a debt has a owner. In instant food, it is all artificial essence additives, trans fatty acids, preservatives, and sugar. Drinking these things every day is strange for health.

"What do you mean by that?"

Good question. Coffee is harmful or good for health. This topic has been stronger than Conan's serial for decades, and there are more disputes than soybean milk sweet and salty. However, most of them are based on speculation and misinformation. In the end, whether the black liquid in this cup is a blessing or a disaster, whether he is the incarnation of immortals or the messenger of hell, it is advisable to synthesize the professional academic achievements and experiences, so that everyone can drink at ease and sleep at ease.

First of all, as mentioned at the beginning, instant coffee is definitely not a healthy drink. People who really love coffee do not drink instant coffee. Some friends say, I don't drink instant coffee anymore. I only drink freshly ground black coffee. I say, good, good. He says, um, I like black coffee with two packs of cream and two pieces of sugar.

Damn, you'd better go back and drink instant coffee. The real and healthy coffee is pure black coffee, of course. In the third wave, if you drink coffee with sugar and cream, you are really embarrassed to say hello to others.

Drinking black coffee without sugar is beneficial to the human body, which is already the consensus of the health community and the scientific community, so what kind of effect does black coffee have on the human body? Let's sort it out.

Nutrients of Coffee

In 2006, Spanish expert Diaz pointed out that freshly brewed coffee contains more water-soluble dietary fiber than orange juice or red wine, and the food industry was shocked.

Not only that, coffee beans are also rich in a variety of vitamins, including folic acid, vitamin B1, vitamin B2, vitamin B3, vitamin B12 and vitamin C, but also contains a lot of antioxidants, in short, a lot of good things. Dr. Vincent American research shows that coffee contains far more antioxidants than tea and fruits and vegetables, Norway intake of antioxidant sources, coffee alone 64%.

Some brothers ask, what exactly are antioxidants? We know that oxygen is the basic element to maintain life. When we inhale oxygen, we will also produce the same by products, namely oxidants-free radicals, which will destroy the structure from the cell level and cause lesions. After coffee roasting, the antioxidant capacity increases sharply, resulting in phenolic acid and protein melanin, which are powerful antioxidants, which can repair cells and effectively inhibit chronic diseases such as cancer, cardiovascular disease, diabetes and Alzheimer's disease. So that the human body long-term health.

Coffee and disease

Recent studies have shown that coffee can increase cell sensitivity to insulin, enhance glucose metabolism, and help prevent diabetes. The Dutch Institute of Public Health says the more coffee you drink, the lower your risk of developing type 2 diabetes (adult diabetes). (Please don't bother me if you insist on sugar, thank you.) People who drink four cups of coffee a day can reduce gout by 40%.

Over the past 20 years, in-depth studies in Japan, the United States, and Europe have consistently found that the more coffee you drink, the less likely you are to develop cirrhosis or liver cancer. German scientists have revealed that espresso can also prevent colon cancer, confirming the role of antioxidants. Now the anti-cancer effect of coffee has been recognized by the academic community, instant coffee really bunkers! Is there anything?

Some friends say they like coffee aroma, but dare not drink it, drink palpitations, or can't sleep. That's right, that's what caffeine does. Caffeine sounds scary, but it's not heroin after all. The scientists calculated that caffeine does not exceed 300 mg per day. The benefits outweigh the disadvantages. It exceeds them from person to person. Everything in the world is too much. Pay attention.

There are two major varieties of coffee, one called Arabica, one called Robusta, Arabica flavor is good and expensive, Robusta flavor is poor and cheap, the two brothers also have a difference, Arabica caffeine content of 1.1-1.5%, Robusta caffeine content is as high as 3.2%. Robusta is everywhere in instant coffee and low-cost blended beans.

Does the type of bean determine how much caffeine? Also not, how much caffeine comes out depends on the time of contact between hot water and coffee powder. The longer the time, the greater the precipitation ratio. American coffee brewing time is long, caffeine comes out the most; French press coffee powder has been soaked in water, also a little higher; enthusiasts favorite hand pot ah siphon pot, three or two minutes end, caffeine has not had time to run out, but the good taste of the substance has run out, so caffeine will not be too high.

But don't underestimate Italians, they use mocha pot to boil a pot of coffee 5 times, in order to boil all the caffeine, called "student coffee", specifically used to learn to refresh, young is good.

In fact, black tea, green tea, cola, chocolate all have caffeine, needless to say, red bull this functional drink caffeine has long exploded table, as long as the intake is appropriate, there is no harm.

In addition, there are also some fatty things in coffee, which are considered to raise cholesterol and are unhealthy substances.
