Black coffee without sweetening can reduce the risk of diabetes

In the morning coffee It is not worthwhile to make sweetening, concludes extensive US research. Namely, coffee in black is associated with a lower risk of developing type 2 diabetes.

Each cup of coffee is 10 % of the risk of diabetes, but adding sugar or even sweetener takes a diabetes protection. On average, the amount of sugar was estimated to be a teaspoon per cup.

Perhaps the surprising result was that adding cream to coffee does not reduce the protective effect of coffee diabetes. But adding milk powder, on the other hand, seems to take protection.

The study that found the benefit of black coffee was based on extensive information. The research material contains information about more than 150,000 people, and nearly 3.7 million follow -up years.

One of the authors is the well -known professor of nutrition at Harvard University Walter Willett. The study was published The American Journal of Clinical Nutrition in the magazine.

“With coffee Generally speaking, consistently, from one population survey, a link to lesser type 2 diabetes has been observed, ”says a professor of nutrition science Mikael Fogelholm by email.

The protective effect of coffee has been manifested in the population, regardless of the amount of exercise, obesity or consumed alcohol. However, there is no final explanation for the observation.

“The mechanism is not well known, but it is thought to be related to, among other things, coffee polyphenols,” Fogelholm says.

A connection between coffee ranges and a reduction in the risk of diabetes in type 2 was observed Health library joined in the Netherlands a couple of decades ago. So the more coffee is drunk, the less diabetes is found.

The same has been observed in population surveys, especially in the Nordic countries and the United States. According to several studies, every cup of coffee consumed reduced the risk of diabetes by 7 %.

Moderate coffee drinking, or 1-4 cups of days, can be part of a healthy diet, says Nordic nutritional recommendations summary. This summary can also reduce the risk of cardiovascular disease and type 2 diabetes.

“Obtained The reduction in the risk in this study, or ten percent per cup, is very similar to that of the average, ”Fogelhom says.

According to Fogelholm, the problem of sugar added to coffee is only when you drink more than three cups a day. This means maybe 15-20 grams of sugar, which is only about one third of the most recommended amount.

“It should not be a decisive amount if the diet otherwise has plenty of sugar. The study has been conducted in the United States, where sugar intake is higher than in Finland, ”Fogehom recalls.

Adding sugar to coffee can also be linked to otherwise unhealthy eating habits.

“Artificial sweeteners work like sugar in this study. The explanation of this may be that persons who, for one reason or another, have originally begun to use artificial sweeteners at the risk of the type of second. ”

On the other hand, the amount of cream may not be very big in those amounts of coffee, so its significance for getting saturated fat is probably reasonably small, Fogelholm ponders.

Follow -up surveys They do not indicate whether the connection is precisely due to coffee. The decrease in the risk of diabetes is apparently due to caffeine. The connections between caffeine and regular coffee and diabetes are similar.

“Population surveys should be carefully interpreted. Nutrition recommendations advise you to avoid using excessive added sugar and that is why you should enjoy coffee without sugar, ”Fogelhom says.
