Medical studies on Apple Cider Vinegar and Insulin Sensitivity

1. Apple Cider Vinegar at mealtime lowers blood glucose levels in diabetes

Johnston, C. S., Quagliano, S., & White, S. (2013) conducted a study to investigate the effects of vinegar ingestion at mealtime on fasting blood glucose concentrations in healthy adults at risk for type 2 diabetes. This study was published in the Journal of Functional Foods and aimed to explore the potential benefits of vinegar as an adjunct therapy for individuals with impaired fasting glucose or type 2 diabetes.

The study involved 14 participants aged between 18 and 65 years who were considered at risk for type 2 diabetes. Participants were identified as at risk based on their fasting blood glucose levels, which were in the range of 95-125 mg/dL. The participants were randomly assigned to two groups: the vinegar group and the control group. The vinegar group received a drink containing 2 tablespoons of apple cider vinegar mixed with 8 ounces of water and 1 teaspoon of saccharin, while the control group received an isocaloric drink that was matched in appearance and taste but contained no vinegar. Participants consumed their assigned drink daily with their evening meal for 12 weeks.

The researchers measured the participants’ fasting blood glucose levels at the beginning of the study, at 4 weeks, 8 weeks, and 12 weeks. They found that the vinegar group experienced a significant reduction in fasting blood glucose levels compared to the control group. The mean reduction in fasting blood glucose levels in the vinegar group was 4.7%, while the control group showed no significant change. This reduction in fasting blood glucose was observed as early as 4 weeks into the intervention and was maintained throughout the study.

The findings of this study suggest that daily vinegar ingestion at mealtime could be effective in reducing fasting blood glucose concentrations in adults at risk for type 2 diabetes. The authors propose that vinegar may have a role as an adjunct therapy for individuals with impaired fasting glucose or type 2 diabetes, helping to improve glycemic control. However, it is important to note that this study had a relatively small sample size, and further research is needed to confirm these findings and determine the long-term effects of vinegar consumption on blood glucose levels.

2. Apple Cider Vinegar with High Glycemic Meals reduces blood sugar response

Another study published in the European Journal of Clinical Nutrition in 2005 found that consuming vinegar with a high-glycemic meal could help reduce blood sugar response by more than 30% in healthy individuals (Ostman et al., 2005).

Ostman et al. conducted a study to examine the effects of vinegar supplementation on glucose and insulin responses and satiety following a high-glycemic meal in healthy individuals. The study, published in the European Journal of Clinical Nutrition, aimed to explore the potential benefits of vinegar in managing blood sugar levels and promoting a feeling of fullness.

The study involved 12 healthy volunteers who consumed three different test meals on separate occasions in a randomized, crossover design. The test meals consisted of white wheat bread, which is a high-glycemic index food, providing 50 grams of available carbohydrates. The meals were supplemented with vinegar (18, 23, or 28 mmol acetic acid), or with a control drink containing water and flavored with lemon. Blood samples were collected before and after the meal to measure glucose and insulin levels. Participants were also asked to rate their subjective feelings of hunger and satiety at regular intervals.

The results showed that vinegar supplementation significantly reduced the postprandial glucose response by 31%, 25%, and 23% for the 18, 23, and 28 mmol acetic acid groups, respectively, compared to the control group. Furthermore, the postprandial insulin response was reduced by 34%, 19%, and 14% for the 18, 23, and 28 mmol acetic acid groups, respectively. These findings suggest that vinegar supplementation can help lower glucose and insulin responses after a high-glycemic meal in healthy individuals.

In addition to the effects on glucose and insulin levels, the study also found that vinegar supplementation increased satiety after the meal. Participants reported a higher feeling of fullness in the vinegar-supplemented groups compared to the control group. This could potentially contribute to better weight management, as increased satiety may help reduce overall caloric intake.

In conclusion, Ostman et al.’s (2005) study demonstrated that consuming vinegar with a high-glycemic meal could help reduce blood sugar response and increase satiety in healthy individuals. However, it is essential to note that more research is needed to confirm these findings in different populations and to understand the long-term effects of vinegar supplementation. 

3. The Effects of Apple Cider Vinegar on Insulin Sensitivtiy after a high carbohydrate meal

In a third study, Johnston et al. (2004) investigated the effects of vinegar on insulin sensitivity in insulin-resistant individuals and those with type 2 diabetes. The study, published in Diabetes Care, aimed to explore the potential benefits of vinegar consumption in improving insulin sensitivity and reducing postprandial blood glucose levels after a high-carbohydrate meal.

The study involved a total of 29 participants, including 10 with type 2 diabetes, 11 with insulin resistance, and 8 who were healthy and served as a control group. The participants were provided with a high-carbohydrate meal, consisting of a bagel, butter, and orange juice. They were randomly assigned to consume either a vinegar solution containing 20 grams of apple cider vinegar, 49 grams of water, and 1 gram of saccharin, or a placebo solution that matched the vinegar solution in appearance and taste but contained no vinegar. Blood samples were collected before the meal and 30 minutes, 60 minutes, and 120 minutes after the meal to measure glucose and insulin levels.

The results of the study showed that the vinegar solution significantly improved insulin sensitivity in both insulin-resistant individuals and those with type 2 diabetes. Insulin sensitivity was increased by 34% in the insulin-resistant group and by 19% in the type 2 diabetes group when they consumed the vinegar solution compared to the placebo solution. Furthermore, the vinegar solution also resulted in reduced postprandial blood glucose levels in both the insulin-resistant and type 2 diabetes groups.

These findings suggest that vinegar consumption before a high-carbohydrate meal can help improve insulin sensitivity and reduce postprandial blood glucose levels in insulin-resistant individuals and those with type 2 diabetes. The study provides evidence supporting the potential role of vinegar in managing blood sugar levels and improving glycemic control in these populations.

However, it is essential to note that the study had a relatively small sample size and short follow-up, and further research is needed to confirm these findings and explore the long-term effects of vinegar consumption on insulin sensitivity and blood glucose levels.

4. The effect of Acetic Acid on glucose uptake in skeletal muscle

In the study by Mitrou et al. (2015), the researchers aimed to investigate the effects of acetic acid, the primary active component of vinegar, on glucose uptake and blood flow rates in the skeletal muscles of humans with impaired glucose tolerance. Impaired glucose tolerance is a condition characterized by higher-than-normal blood glucose levels, which increases the risk of developing type 2 diabetes. The focus of this study was to better understand the potential benefits of vinegar consumption on blood sugar control in this specific population.

The researchers recruited 8 participants with impaired glucose tolerance who were asked to consume a vinegar drink containing 20g of acetic acid or a placebo drink. The study used a randomized, double-blind crossover design, meaning that participants underwent two separate trials with a one-week washout period between them. During each trial, participants consumed either the vinegar drink or the placebo drink, and their glucose uptake and blood flow rates in skeletal muscles were assessed using a combination of blood sampling and imaging techniques.

The results of the study revealed that acetic acid ingestion led to an increase in glucose uptake by skeletal muscles and improvement of blood flow rates compared to the placebo group. Specifically, glucose uptake in the forearm muscles increased by an average of 50% following acetic acid consumption. Additionally, blood flow rates increased by approximately 40% in the same muscle group.

These findings suggest that acetic acid, and by extension, vinegar consumption, may have the potential to improve glucose uptake in skeletal muscles and enhance blood flow, which could contribute to better blood sugar control in individuals with impaired glucose tolerance. It is important to note that this study had a small sample size of only 8 participants, and the results should be interpreted with caution. Further research is needed to confirm these findings and explore the mechanisms underlying the observed effects of acetic acid on glucose uptake and blood flow in skeletal muscles.

The study by Mitrou et al. adds to the growing body of evidence supporting the potential benefits of vinegar consumption for blood sugar control. While vinegar should not replace traditional diabetes management strategies, it could be considered as an adjunct therapy for individuals with impaired glucose tolerance or type 2 diabetes. As always, it’s essential to consult a healthcare professional before incorporating apple cider vinegar or any other supplements into one’s diet, especially for those with pre-existing medical conditions.

5. Scientifitic review on the effects of apple cider vinegar on glucose and lipid levels and body weight

Petsiou et al. (2014) conducted a comprehensive review of the available literature to examine the effects of vinegar on glucose metabolism, lipid profile, and body weight. This review article focused on understanding the potential benefits of vinegar, particularly apple cider vinegar, for individuals with type 2 diabetes or insulin resistance. The authors reviewed several studies, including clinical trials and animal experiments, to gain insights into the mechanisms of action and the effectiveness of vinegar in managing these health issues.

One of the key findings of the review was that vinegar could improve glycemic control in individuals with type 2 diabetes or insulin resistance. The authors found that vinegar consumption, particularly in the form of acetic acid, could lower blood glucose levels by increasing glucose uptake by cells, improving insulin sensitivity, and reducing glucose production in the liver. These effects are particularly beneficial for people with type 2 diabetes, as they often struggle with insulin resistance and high blood sugar levels.

The review also highlighted the potential benefits of vinegar on lipid profiles. Some studies included in the review reported that vinegar could reduce total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides, while increasing high-density lipoprotein cholesterol (HDL-C) levels. These improvements in lipid profiles could help reduce the risk of cardiovascular disease, which is often associated with diabetes and insulin resistance.

Additionally, the authors discussed the potential impact of vinegar on body weight. While the results were not as consistent as those on glucose metabolism and lipid profiles, some studies suggested that vinegar consumption might help reduce body weight and adiposity by promoting satiety, increasing energy expenditure, and modulating lipid metabolism.

The review also delved into the possible mechanisms of action underlying the observed effects of vinegar on glucose metabolism, lipid profile, and body weight. The authors suggested that acetic acid, the main active component of vinegar, could activate specific enzymes and signaling pathways involved in glucose and lipid metabolism, as well as energy homeostasis. However, more research is needed to fully understand these mechanisms and their implications for human health.

In conclusion, Petsiou et al.’s (2014) review article provides substantial evidence to support the potential benefits of vinegar consumption for individuals with type 2 diabetes or insulin resistance. The findings suggest that vinegar could improve glycemic control, insulin sensitivity, lipid profiles, and possibly body weight, offering a promising adjunct therapy for managing these health conditions. While the review highlights the positive effects of vinegar on these health markers, it is essential to recognize that further research is needed to confirm these findings and establish the optimal dosage and duration of vinegar supplementation for the most effective outcomes.

6. The effect of Apple Cider Vinegar at bedtime on fasting glucose levels of diabetes

In the study conducted by White and Johnston (2007), the researchers sought to examine the impact of vinegar ingestion at bedtime on fasting blood glucose concentrations in adults with well-controlled type 2 diabetes. This investigation was prompted by the growing interest in the potential benefits of apple cider vinegar, particularly its acetic acid content, for blood sugar control and overall diabetes management.

The study involved 11 participants with well-controlled type 2 diabetes, who were not using insulin therapy. Over the course of two days, participants consumed either two tablespoons of vinegar or a placebo (water) along with one ounce of cheese at bedtime. The researchers measured participants’ fasting blood glucose levels the following morning, comparing the results between the vinegar and placebo groups.

The findings of the study revealed that vinegar ingestion at bedtime led to a statistically significant reduction in fasting blood glucose levels compared to the placebo group. Specifically, those who consumed vinegar experienced an average decrease of 4% in their fasting blood glucose concentrations, whereas the placebo group saw a slight increase of 2%. The results suggest that vinegar may have a beneficial effect on fasting blood glucose control in individuals with type 2 diabetes.

It’s important to note that this study had a small sample size and a short duration, which means that the findings should be interpreted with caution. Nevertheless, the results provide preliminary evidence supporting the potential benefits of vinegar consumption for individuals with type 2 diabetes. Further research with larger sample sizes and longer durations is needed to confirm these findings and to explore the optimal dosage and timing of vinegar ingestion for effective blood sugar control.

In addition to the potential benefits of vinegar for blood sugar control, the study highlights the importance of considering lifestyle and dietary factors in the management of type 2 diabetes. 

CONCLUSION

In conclusion, the research on apple cider vinegar and its potential benefits for blood sugar control and overall health is promising. Several studies have demonstrated that vinegar consumption, particularly in the form of acetic acid, can help regulate blood sugar levels, improve insulin sensitivity, and positively influence lipid metabolism.
