1. Alcohol

Many studies have examined the effects of alcohol intake on blood sugar control. These have subsequently been pooled and meta-analyzed to arrive at a more reliable conclusion.

A 2015 meta-analysis that looked at 14 studies on humans found that moderate alcohol consumption improves blood sugar control (it lowers HbA1c). Moreover, the analysis found that alcohol consumption increases insulin sensitivity in women.1

A 2006 meta-analysis found that type 2 diabetics who consume moderate amounts of alcohol have a lower risk of dying, compared to alcohol abstainers.2

Another study on type 2 diabetics found that moderate alcohol consumers had a lower risk of new or worsening diabetic kidney disease or eye disease (retinopathy), and a lower risk of death, compared to alcohol abstainers. The protective effects were larger for those who drank mostly wine.3

Heavy alcohol consumption leads to a greater risk of death, however,3 and should be avoided.

Whether or not you should start drinking is a personal choice that must also take into account the risk of accidents and addiction.

2. Aronia juice

You may never have heard of aronia juice, but you can buy it in many places if you look around. Aronia is also known as chokeberry, or black chokeberry. Studies have shown that aronia berries/chokeberries are antidiabetic.

In one study, diabetics who drank one glass (2 deciliters) of sugar-free, artificially sweetened, aronia juice had 20% lower blood sugar after just one hour.4

Remarkably, diabetics that consumed the juice with a carbohydrate-rich breakfast had 11% lower blood sugar after one hour. In other words, the juice prevented and reversed the usual blood sugar spike seen after a high-carbohydrate meal.4

Furthermore, drinking one glass (2 deciliters) of the juice per day for 3 months reduced fasting blood sugar by 31% in type 2 diabetics.4 The juice also reduced HbA1c, cholesterol and blood fats.4

If you can’t find sugar-free juice, get one with naturally occurring sugar. Studies in rats have demonstrated that aronia juice is antidiabetic even if it contains some sugar.5

Another tip is to buy aronia powder, that you turn into juice by adding water. It may be more practical and convenient.

3. Chamomile tea

Chamomile has antidiabetic properties that have been demonstrated in type 2 diabetics,6 and several rodent studies.7-11

In a human study, type 2 diabetics were instructed to drink 1.5 deciliters of chamomile tea (5 fl oz) three times per day immediately after each main meal, while the control group consumed water. After 8 weeks, the chamomile tea group had significantly lower HbA1c, insulin resistance, cholesterol, blood fats (triglycerides) and LDL cholesterol, compared to the control group.6

Based on this, drinking chamomile tea immediately after each major meal seems like a good strategy to control blood sugar.

4. Cranberry juice

In one study, type 2 diabetics were randomly assigned to consume 1 cup (240 milliliters) of cranberry juice per day for 12 weeks, or a placebo drink. By the end of the study, blood sugar was significantly lower, and heart disease risk factors were improved, in the cranberry juice group compared to the placebo group.12

In another study, overweight, middle-aged, adults consumed either 2 cups per day of sugar-reduced cranberry juice for 8 weeks, or a placebo drink. Cranberry juice reduced fasting blood sugar, insulin resistance, blood pressure and inflammation, compared to placebo.13

As always, try to find a low-sugar or low-calorie variety, even if it’s artificially sweetened. Supplements or berries may also be effective.

5. Green tea

A multitude of studies have examined the effects of green tea on blood sugar control. Due to the large amount of studies, the results have subsequently been pooled and meta-analyzed in an attempt to get a more accurate picture.

One such meta-analysis, published 2013, included 17 trials with 1133 participants and found that green tea consumption indeed reduces fasting blood sugar and HbA1c.14

6. Guava leaf tea

Guava leaf tea is approved in Japan for prediabetics as a ”Food for Specified Health Uses”, thanks to its antidiabetic properties.15

Specifically, human studies have found that drinking guava tea before eating carbohydrate reduces post-meal blood sugar (reduces glycemic index).15

Longer-term studies found that drinking guava tea with every meal for 12 weeks reduced insulin resistance in type 2 and prediabetics.15

Based on these findings, drinking guava leaf tea with meals, especially carbohydrate-rich meals, is helpful for controlling blood sugar levels.

7. Marjoram tea

Marjoram tea is beneficial for women with polycystic ovary syndrome (PCOS), a hormonal disease which, just like diabetes, is characterized by insulin resistance.

In a recent study, women with PCOS were assigned to consume a cup of marjoram tea or placebo tea twice daily for 1 month. By the end of the study, insulin resistance was significantly lower in the marjoram tea group.16

Marjoram tea can be purchased as tea bags, or you can brew your own with marjoram spice and boiling water.

8. Pomegranate juice

Studies on humans demonstrated that pomegranate juice improves blood sugar control, and can reduce cholesterol and blood pressure, too.17-19

Another study found a neutral effect on blood sugar, but found that pomegranate juice was anti-inflammatory.20

An animal study is also worth mentioning. A pomegranate rind supplement reduced blood sugar by 48% in just 6 hours in diabetic mice. It also improved nerve function and reduced pain caused by peripheral diabetic neuropathy.21

As always, try to find juice with a minimal amount of sugar and calories, even if it’s natural sugar.

9. Red wine

As mentioned, alcohol itself improves blood sugar control (HbA1c). Red wine may be even healthier thanks to various plant compounds, like resveratrol.

Moderate amounts of red wine consistently improves health in diabetics. 22-26

For example, drinking 360 ml (12 fl oz) of red wine per day resulted in significantly higher insulin sensitivity in type 2 diabetics, in just two weeks.22

In another study, on type 2 diabetics who had recently suffered a heart attack, one small glass of red wine per day for 1 year reduced insulin resistance and inflammation, and improved heart function and HDL cholesterol.23

A glass of red wine per day can also improve liver health in type 2 diabetics,24 reduce blood sugar, and make it easier to fall asleep at night.25

Red wine even benefits type 2 diabetics with kidney disease. A study found that one small glass per day for 6 months improved kidney health – an effect not seen with white wine, or without alcohol altogether. 26

Clearly, type 2 diabetics can benefit from moderate red wine consumption. An appropriate amount would be around 1.2 to 3.6 dl daily (4 to 12 fl oz) – or 1 to 3 small glasses – which I think is best consumed with dinner. This minimizes the risk of accidents.

Whether or not you should start drinking is a personal choice that must also take into account the risk of accidents and addiction.

10. White mulberry tea

Studies have shown that white mulberry leaves reduce fasting blood sugar, HbA1c and insulin resistance in humans.27

The berries may also be antidiabetic, but I haven’t seen any research on that. Your best bet is a white mulberry tea or supplement. White mulberry tea can be purchased in many health food stores. If you can’t find it locally, look online.

11. Yerba mate tea

Yerba mate is a plant most known for its weight loss effects. However, studies also show that yerba mate has antidiabetic properties.

In type 2 diabetics, drinking 1 liter (roughly 1 quart) per day of yerba mate tea for 2 months significantly reduced fasting blood sugar and HbA1c, and improved cholesterol as well.28

Yerba mate tea is available in many health food stores.

12-20. Other drinks

Here are 9 more scientifically proven drinks that can reverse your diabetes (and improve your health in other ways):

  1. Aloe vera juice. In diabetics, one tablespoon of aloe juice twice a day reduced blood sugar.29, 30
  2. Blueberry juice. The antidiabetic effects of blueberry juice are documented.
  3. Cocoa. A meta-analysis published in 2011, which pooled the results of 24 studies of cocoa on 1106 participants, found that cocoa consumption reduces insulin resistance, blood pressure and LDL cholesterol, and raises HDL cholesterol.31 Cocoa, of course, can be consumed as a beverage. Simply add cocoa powder to hot water and stir. Add stevia as a sweetener if desired.
  4. Fenugreek. A study on type 2 diabetics found that 10 grams per day of fenugreek powder mixed with hot water led to a 25% reduction of fasting blood sugar in 8 weeks.32
  5. Indian gooseberry juice. Indian gooseberries are also known as alma fruit. In diabetic rats, the juice reduced blood sugar.33
  6. Onion juice. Animal studies have demonstrated that onion juice (as well as freeze-dried onion powder, and other onion preparations) has antidiabetic effects.34
  7. Plum juice. Obese rats given Asian plum juice (Prunus Mume) had lower blood sugar and higher insulin sensitivity compared to rats given water.35
    In another study on obese rats, juice made from purple plums attenuated weight gain by reducing calorie intake, and reduced blood sugar and insulin resistance, compared to a similar amount of water with added sugar.36
  8. Tomato juice. In patients with the metabolic syndrome, drinking tomato juice 4 times per week for 8 weeks significantly reduced insulin resistance, inflammation and cholesterol.37
  9. Vinegar diluted in water. Vinegar is well documented to improve blood sugar control. Diluted in water, it makes for a refreshing drink.
