The Mystery of Apple Cider Vinegar: Insights from a Nutrition Expert

Listen to this article.

Apple cider vinegar is a popular liquid that many people say is good for health. They believe it can help you lose weight and make your body use sugar better. As someone who knows a lot about food and health, I often hear people talk about this vinegar. But, even though many people use it and like it, scientists are still trying to figure out if it really works as well as people say.

The Health Halo Effect

Apple cider vinegar has acquired what is often referred to as a health halo—a perception of being inherently healthy and beneficial, which can sometimes lead consumers to prioritize it over other dietary choices. This phenomenon is not new to the nutrition world; we’ve seen similar trends with “superfoods” and the emphasis on protein-enhanced products.

A True Story

John is in his late 50s and hasdiabetes. He had heard about the potential benefits of apple cider vinegar for controlling blood sugar levels. He decided to try incorporating it into his daily routine to see if it could help manage his condition. Every morning, John began to drink a mixture of two tablespoons of apple cider vinegar diluted in a large glass of water before breakfast.

After several weeks, John noticed a significant improvement in his blood sugar control. His fasting blood sugar levels were lower, and his post-meal spikes were less pronounced. He told his doctor about his experience after seeing these results with excitement. His doctor was cautiously optimistic, noting that while there’s some evidence suggesting vinegar might help improve insulin sensitivity, it should not replace medical treatment but could be used as a supplementary measure.

John continued with his routine and also made sure to monitor his health closely with his healthcare provider. This anecdote highlights that while natural remedies like apple cider vinegar can have beneficial effects for some people, they should be approached with care and ideally under medical supervision.

The Science Behind the Claims

Apple cider vinegar (ACV) has been studied for its potential health benefits, but scientific evidence regarding its efficacy is mixed. Some research suggests that ACV may help improve insulin sensitivity and reduce blood sugar levels.

For instance, a study published in the Journal of Diabetes Research found that consuming vinegar before meals improved insulin sensitivity by 19–34% during a high-carb meal and significantly lowered blood sugar and insulin responses.

In terms of weight loss, studies have shown modest results. A randomized controlled trial conducted over 12 weeks observed that participants who consumed vinegar daily had a slight reduction in body weight. The average weight loss was about 1-2 kilograms (2.2–4.4 pounds) compared to the control group that did not consume vinegar.

Here is a table summarizing the findings from key studies on apple cider vinegar:

Main Findings

Insulin Sensitivity29 individuals with insulin resistanceSingle mealImproved insulin sensitivity by 19–34% during high-carb meal
Weight Loss175 obese individuals12 weeksAverage weight loss of 1-2 kilograms (2.2–4.4 pounds)

These results indicate that while ACV might offer some health benefits, particularly in the areas of glycemic control and weight management, it is not a cure-all solution. The effects are relatively modest, and its use should be combined with other lifestyle and dietary changes for best results.

Beauty and Skincare Uses

One of the benefits of ACV is the effect it has on your skin. ACV can help improve your complexion. Skin can look younger, and age spots can lessen with ACV. Vinegar has been used for various skin ailments, and it is also effective in treating a lot of skin conditions. Diluted ACV applied with a cotton ball to your skin can help with acne. The vinegar has antiseptic properties and can also kill bacteria and germs that lead to outbreaks. By doing this, you can promote smooth and silky skin.

Furthermore, skin toner can be made from one part ACV and two parts water. Apply this to clean skin, then leave for around ten minutes. There is no need to rinse it off, and the smell will go away once it dries. This treatment can also help with acne. Dry skin can benefit from this too, as ACV can help balance the pH of your skin. Apple cider vinegar can also work as an alternative to regular deodorants and actually keep body odor away. Due to its antibacterial properties, it will be strong enough to reduce, and even eliminate underarm odor.

Precautions and Side Effects

One of the main disadvantages of using apple cider vinegar as a medicine is that it may have a damaging effect on your tooth enamel. A case study was published in 2012 of a 15-year-old girl who consumed 1 cup of undiluted apple cider vinegar per day as a weight loss aid and suffered significant damage to her teeth as a result. The acetic acid in the vinegar is thought to be the cause.

Vinegar has also been known to cause or worsen low potassium levels. The effects of low potassium levels include muscle cramps, weakness, and fatigue. The study of the 15-year-old girl noted that she reported feeling fatigued and that her physician found low blood potassium levels. Although this is just one case, and there may be other factors that resulted in these low potassium levels, it is still a precaution for those with other health conditions that may affect their potassium levels, such as those taking insulin for diabetes.

Many articles can be found on the internet with lists of other possible drug interactions or conditions that may make it unsafe to consume apple cider vinegar, however, there is very little evidence in the form of published studies that these claims are true. Nonetheless, it is a good idea to be cautious and start with small doses if you are unsure, as anything that can have effects as powerful as dissolving a wart or corn should be thoroughly researched before being used as an everyday food or drink.


While apple cider vinegar continues to intrigue both the public and the scientific community, its status as a panacea for health woes is yet to be confirmed. As with any dietary supplement or health product, individual responses may vary, and what works for one person may not work for another. The pursuit of a balanced diet and a healthy lifestyle should remain at the forefront of our wellness journeys, with apple cider vinegar potentially playing a role, but not overshadowing the fundamentals of good nutrition and self-care.
