Convenience store automatic coffee machine, drip filter paper filter, no matter what kind of coffee extraction form, as long as do not drink too much (not more than about 600 milliliters a day).

Recently, it has become the most ramming new self-media platform, and as a result, many pseudoscience elders have been made into audio-visual versions and put them on the spread, among which "without this action, convenience store coffee will actually cause harm to the body." It's really terrible. "A film, a scary subscript that combines the argument of content farm plagiarism, has successfully attracted many viewers to click on it, but its content is actually fallacious.

In the film, coffee oil alcohols can lead to higher blood cholesterol, but if they are filtered by filter paper, most coffee oil alcohols can be removed and the harm can be reduced. Relatively speaking, if you drink convenience store coffee that is not extracted by filter paper, it will contain a lot of coffee oil alcohol, and the consequences of drinking too much will be very terrible.

But what is the truth? In fact, the film has some over-guided inferences about "convenience store coffee" and "the harm of caffeine".

Caffeine alcohol causes the body to create "OOXX is really scary!" Is it harmful?

In 2013, "Maturitas" and many previous studies did mention the harmful effects of coffee on "blood lipids", such as increasing total cholesterol, low density lipoprotein cholesterol and triglycerides, but what the film does not say is that it also has protective effects, such as reducing the ratio of low density lipoprotein cholesterol to high density lipoprotein cholesterol and reducing oxidized low density lipoprotein cholesterol. At present, there is no clear conclusion that it is really beneficial or harmful. A 2008 FEBS Lett study even identified caffeine as a protective factor for neurons associated with Parkinson's disease.

Furthermore, the results of studies on coffee drinking and "cardiovascular disease" are also quite inconsistent. In 2004, a Finnish study said that the effect of coffee on cardiovascular disease was Jmurshape; another prospective generation study in 2006 "Circulation" said that coffee had no effect on the human body, and "Lowa Women's Health Study" even believed that coffee drinking in postmenopausal women could reduce the incidence of inflammation and cardiovascular disease. In a 2007 study, a comprehensive analysis of 13 literatures showed that drinking more than 5 cups of coffee a day was not good for the heart and blood vessels, according to a comprehensive analysis of more than 9, 000 patients with heart disease and more than 20, 000 control groups. however, there was no effect after analyzing 10 other studies with a total population of 400000 in the same study.

A more recent 2015 Harvard study found that caffeine and decaffeinated caffeine "reduced" the risk of death from cardiovascular disease, neurological disease and type 2 diabetes. these data also support the 2015 Dietary guidelines to include moderate coffee consumption in the daily healthy diet recommendations of the American people.

Therefore, as long as you do not drink too much, coffee may still have more health benefits than disadvantages, such as coffee and reducing Alzheimer's, Parkinson's disease, respiratory infections, and reducing the risk of cancer and death in the large intestine, liver and prostate gland. Unless you already have hyperlipidemia, familial cardiovascular disease and other problems, don't drink too much "unfiltered" coffee in one day. Coffee with no more than 600 milliliters (about 300 milligrams of caffeine) a day still doesn't need to worry too much.

The literature clearly says "unfiltered" coffee, convenience store coffee is also shot lying down?

Coffee is roasted and brewed in many ways, and the concentration of caffeine produced by each method is also different. usually, the longer the roast, the faster the brewing, and the lower the water temperature, the lower the caffeine content, so not all coffee contains too much caffeine. for example, there is only a small amount of caffeine in drip coffee with filter paper, filter net and filter cloth. And if the European-style boiling coffee, Turkish coffee, French filter pressure and other brewing methods will be higher.

On the other hand, household fully automatic coffee machines, Italian coffee machines, etc., are not unfiltered coffee, but are filtered by more than double-layer fine filters, and the flow time is not as long as boiled coffee and French filter coffee. Therefore, the caffeine content of convenience store coffee tends to be in the middle, so the truth should be "coffee addicts with hyperlipidemic diseases, the first thing to pay attention to is not to drink too many cups of coffee. In particular, don't drink too much unfiltered coffee. "Don't drink coffee in convenience stores, it's terrible." this is a bit of nonsense, so let it go with the wind.
