How does water lower blood sugar

Bedtime vinegar lowers morning blood sugar

(16.01.2008) Sometimes there are very simple remedies that can help to get a better grip on type 2 diabetes. Scientists from the USA have shown in a small study that the "consumption" of vinegar has a positive effect on the glucose level: If you are a type 2 diabetic who takes a tablespoon of apple cider vinegar before going to bed, you may experience slightly lower blood sugar levels the next morning looking forward.

Various studies have already come to the result in the past that vinegar in food can have a positive effect on excessive blood sugar levels. So far, however, one only had the effects on postprandial blood sugar - i.e. H. for glucose levels immediately after eating - examined. Scientists led by Carol S. Johnston from Arizona State University in Mesa, USA, have investigated the question of the influence of a small dose of vinegar before going to bed in a new study.

Four men and seven women between the ages of 40 and 72 took part in the small pilot study. All persons were type 2 diabetics who were taking different diabetes medications. The only exception: insulinized diabetics were excluded from the study. The men and women adhered to a precisely defined menu for several days. During this time, blood sugar levels were measured every morning around 7:00 a.m. After the third day, study participants consumed either one tablespoon of apple cider vinegar or one tablespoon of water before bed for three nights in a row. The vinegar or the water were given together with a small piece of cheese (approx. 30 g with 8 g protein, 1 g carbohydrates and 1.5 g fat). Nothing changed about the previous diabetes medication. After a washout phase of another 3-5 days, the groups changed: Those who had previously taken vinegar now received water, and vice versa.

The result: The small vinegar and cheese meals before going to bed had a positive effect on blood sugar levels the next morning. On average, the glucose level measured around 7:00 a.m. was almost 5 mg / dl lower. If the vinegar was replaced by water, however, the blood sugar levels were reduced by only about 2.5 mg / dl the next morning. The differences between the "vinegar group" and the "water group" were statistically significant in this study. Type 2 diabetics benefited most with a glucose level above 130 mg / dl in the morning. Here, the additional vinegar intake before going to bed caused the morning blood sugar to be lowered by around six percent. In the case of diabetics with a fasting blood sugar below 130 mg / dl, the values ​​were “only” reduced by about 0.7 percent in comparison.

The conclusion of the scientists: In type 2 diabetics with high fasting blood sugar levels, vinegar may have a beneficial effect on the evening menu. A tablespoon before bed can help lower some morning blood sugar levels. However, further studies still have to clarify how sensible it is to "enjoy" vinegar on a regular and permanent basis.
