It's official—the surprising effect of apple cider vinegar on blood glucose—what studies reveal about taking it before eating and why it's not a miracle cure

Apple cider vinegar is increasingly present in home kitchens. Its benefits are becoming increasingly well-known, especially for digestion, metabolism, and glucose levels, as we will explain in this article. Studies show that vinegar can reduce blood sugar levels after a meal when paired with meals rich in complex carbohydrates. Some research suggests that it contributes to healthier blood sugar levels if used consistently.

This component slows the digestion of starches, reducing how quickly glucose enters the bloodstream

Apple cider vinegar has almost endless benefits. It has been used as a home remedy for sore throats, indigestion, and general well-being in many cultures for centuries. Apple cider vinegar, on the other hand, contains acetic acid. This component slows the digestion of starches, reducing how quickly glucose enters the bloodstream. In addition to reducing blood glucose levels, apple cider vinegar can help increase insulin sensitivity and decrease the post-meal insulin response when consumed with a high-carb meal.

Experts note that the vinegar’s effects aren’t a cure-all and work best alongside proven strategies

Lowering cholesterol levels is also a very relevant factor in the benefits of apple cider vinegar. According to studies, it can lower cholesterol and improve heart health. Experts note that the vinegar’s effects aren’t a cure-all and work best alongside proven strategies like a balanced diet, exercise, and prescribed medication. Several animal studies have shown that vinegar can reduce blood triglycerides, cholesterol, and blood pressure. This could potentially reduce the risk of developing heart disease.

Some studies suggest regular use could support long-term blood sugar control

It’s also worth noting that most of the research supporting the positive health effects of apple cider vinegar has been conducted on animals, and this is often considered weak evidence. Some studies suggest regular use could support long-term blood sugar control. A meta-analysis found significant reductions in glucose and A1C among people with type 2 diabetes who took 15 to 30 milliliters (1 to 2 tablespoons) daily for at least eight weeks. While this is promising, experts stress that vinegar alone is not enough.

Vinegar delays gastric emptying, which slows food’s arrival in the intestine, lengthening the digestion process

Among other benefits, this is one of the most talked about, especially on social media. It’s about metabolism and hunger control: satiety. Some studies have found that vinegar can reduce hunger by increasing the feeling of satiety, helping people eat fewer calories. Technically, vinegar delays gastric emptying, which slows food’s arrival in the intestine, lengthening the digestion process and hindering the breakdown of carbohydrate molecules, making our body absorb them more slowly. Some studies suggest it can help you feel fuller after meals, which may support weight management when paired with healthy eating.

Excess vinegar can worsen a condition called gastroparesis, which involves a malfunction of the nerves in the stomach, making it difficult to empty

According to data, the acidity in apple cider vinegar may help regulate stomach acid levels and help with mild indigestion in some people. It’s also important to note that vinegar can cause stomach irritation in some people. Excess vinegar can worsen a condition called gastroparesis, which involves a malfunction of the nerves in the stomach, making it difficult to empty. These benefits are still being studied, and none replace proven medical treatments or a healthy lifestyle. Therefore, it’s important to remember that before implementing any dietary changes, it’s essential to consult a doctor or other experts.
