How to drink coffee healthily? The most detailed coffee interpretation!

A friend asked, "I heard that drinking coffee is good for your health." I said, "Yes!" He said, "if 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!" "Damn!"

As the saying goes, there are all kinds of artificial flavor additives, trans fatty acids, preservatives and sugars. It is no wonder that you are healthy if you drink these things every day.

"how should I drink it to be healthy?"

That's a good question. The topic that coffee is harmful or healthy has been stronger than Conan's serial over the past few decades, and there are more disputes over sweet and salty soybean milk, but it is mostly speculation and misinformation about whether the black liquid in this cup is a blessing or a curse, whether he is the embodiment of an immortal or an emissary of hell, might as well synthesize professional academic achievements and experience, so that everyone can drink and sleep at ease.

First of all, as I said at the beginning, instant coffee is definitely not a healthy drink, and people who really love coffee do not drink instant coffee. Some friends said, "I no longer drink instant coffee. I only drink freshly ground black coffee." I said, "that's good. Children can be taught." he said, well, I like black coffee with two packets of cream and two sugars.

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

It is already a consensus in the health and scientific circles that moderate consumption of unsweetened black coffee is good for the human body, so what is the effect of black coffee on the human body? Let's study it by category.

The nutrients of coffee

In 2006, Diaz, a Spanish expert, pointed out that brewing coffee contained more water-soluble dietary fiber than orange juice or red wine.

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, as well as a lot of antioxidants. Dr. Vincent Yankee has shown that coffee contains far more antioxidants than tea and fruits and vegetables, and coffee accounts for 64% of the sources of antioxidants consumed by Norwegian.

A brother asked, what are antioxidants? we know that oxygen is the basic element that sustains life. When we inhale oxygen, we also produce a by-product, that is, oxide-free radical, which destroys the structure from the cellular level and causes pathological changes. After coffee is roasted, the antioxidant capacity increases sharply, and phenolic acid and protein melanin are powerful antioxidants that can repair cells. Effectively inhibit chronic diseases such as cancer, cardiovascular disease, diabetes and Alzheimer's disease, so as to keep the human body healthy for a long time.

Coffee and Disease Prevention

Recent studies have shown that coffee can increase the sensitivity of cells to insulin, enhance glucose metabolism, and contribute to the prevention of diabetes. The Dutch Institute of Public Health says the more coffee you drink, the lower the risk of developing type 2 diabetes (adult diabetes). (those who insist on adding sugar please don't bother me, thank you.) people who drink four cups of coffee a day can reduce the incidence of gout by 40%.

Over the past two decades, in-depth studies have been conducted in Japan, the United States and Europe, and it has been found that the more coffee you drink, the less likely you are to develop liver cirrhosis or liver cancer. German scientists have successively revealed that espresso can also prevent colon cancer, confirming the role of antioxidants. Nowadays, the anti-cancer effect of coffee has been recognized by the academic circles, and coffee is really awesome in an instant! Yes or no!

About caffeine.

Some friends say they like the smell of coffee, but they don't dare to drink it, have palpitations, or can't sleep. Yes, that's what caffeine does. The name caffeine sounds scary, but after all, it's not heroin. Scientists have calculated that caffeine no more than 300 milligrams a day has more advantages than disadvantages, which varies from person to person.

There are two kinds of coffee, one is Arabica and the other is Robsta. Arabica is good and expensive, while Robusta is poor and cheap. There is another difference between the two brothers. Arabica caffeine content is 1.1-1.5%, Robusta caffeine content is as high as 3.2%. Robusta can be seen everywhere in instant coffee and low-priced beans.

Does the variety of beans determine the amount of caffeine? No, how much caffeine comes out depends on the time it takes for hot water to come into contact with coffee powder. The longer the time, the greater the proportion of caffeine. American coffee takes a long time to brew, and caffeine comes out the most; French presser coffee powder is always soaked in water and is a little higher; enthusiasts' favorite hand flushing pot and siphon pot, at the end of three or two minutes, caffeine has not yet come out, but all the delicious substances have come out, so caffeine will not be too high.

Espresso looks thickest. Is caffeine the highest? No, because the Espresso extraction time is shorter, there is less caffeine, but some Robusta spaghetti beans are higher. But don't underestimate the Italians. They use a mocha pot to cook a pot of coffee over and over five times in order to boil out all the caffeine, called "student coffee". It's good to be young.

In fact, black tea, green tea, cola, chocolate all contain caffeine, needless to say Red Bull this functional drink caffeine has long been out of the table, as long as the intake is appropriate, it is not a big deal.

In addition, there are some greasy things in coffee, which are thought to raise cholesterol and are unhealthy substances. This solution is simpler. The filter paper is filtered and all is filtered out. Therefore, using a filtered drip filter siphon pot to make coffee is a relatively healthy way to drink.

​

To sum up, drink coffee healthily and observe the following points:

1. don't overdo it. Two or three cups a day will be fine.

2. Choose good varieties, choose on-site grinding, and drink less instant solution.

3. Learn to enjoy black coffee without milk and sugar

Well, once you have mastered the healthy way of drinking and the principle of coffee, you can hold the beneficial substances as you like, avoid the useless ingredients, and pick up the coffee cup with peace of mind, toward the future where there is no sore waist, no leg pain, no hypertension, no diabetes, no liver cirrhosis, no cancer.
