American research: drinking fruit vinegar before meals is good for losing weight.

Recent research shows that fruit vinegar is beneficial to control blood sugar, lose weight and enhance insulin sensitivity. Therefore, diabetics may wish to try "vinegar therapy".

The study came from the annual meeting of the American Nutrition Association. At the meeting, researchers from the Nutrition Department of Arizona State University said that they found that people who used 20 grams of fruit vinegar with meals had 35% lower postprandial blood sugar and lower hunger than those who did not drink. At the same time, the European Journal of Clinical Nutrition also published relevant research done by Lund University in Sweden. They called volunteers to study the effect of vinegar on postprandial blood sugar and insulin. During the experiment, the experimental group was jealous and soaked in white bread, while the control group ate white bread without vinegar. The results showed that the blood sugar and insulin of people who were jealous of making bread were lower than those of the control group 30 minutes after meal, and those who loved bread felt hungry and were not easy to get hungry. Dr. Li Changhong from the University of Pennsylvania School of Medicine told reporters that even eating two spoonfuls of vinegar before meals will be very helpful to control the blood sugar and weight of diabetic patients and increase insulin sensitivity. Moreover, obese people can lose weight by drinking vinegar.

Why does vinegar have such an effect? Studies have shown that acetic acid can inhibit disaccharidase, reduce the glycemic index of food and increase glucose -6- phosphate in skeletal muscle, similar to glucosidase inhibitors and metformin. However, Dr. Li Changhong emphasized that it may not be just acetic acid that plays a role in vinegar.

Dr Li Changhong suggested that people with bad stomachs, especially patients with gastric ulcer, should be extra careful. If you have too much stomach acid, you'd better not be jealous too much. In addition, it depends on whether the fruit vinegar contains sugar and how much sugar it contains. If the sugar content is too high, it is not suitable for diabetics to drink.
