There are no official guidelines concerning taking vinegar internally. Some people take one to two teaspoons a day, mixed in a glass of water, before meals or in the morning, and report benefits from doing so. Research suggests it may have some real health benefits.
Diabetes
Vinegar is said to be anti-glycemic and has a beneficial effect on blood sugar levels. It’s thought that the acetic acid in vinegar may lower blood sugar by preventing the complete digestion of complex carbohydrates, which is accomplished either by accelerating gastric emptying or increasing the uptake of glucose by bodily tissues.
One theory is that vinegar might inactivate some of the digestive enzymes that break down carbohydrates into sugar, thus slowing the conversion of complex carbohydrate into sugar from a meal into your bloodstream.
This gives your body more time to pull sugar out of your blood, preventing your sugar levels from spiking. Quite a bit of research supports the use of vinegar as a diabetic treatment as well.
Heart Health
Vinegar supports heart health in multiple ways.
One study showed that vinegar could lower cholesterol in laboratory rats, while another study on rats found their blood pressure could be lowered by the acetic acid in vinegar.
Vinegar has also been found to decrease triglyceride levels and VLDL levels (the damaging form of cholesterol) in animal studies.
Weight Loss
Vinegar may help you lose weight, as it appears to have an anti-obesity effect by increasing satiety and reducing the total amount of food consumed.
In addition, separate research found taking vinegar along with bread not only lowered glucose and insulin responses, but also increased levels of satiety. The rating of satiety was directly related to the acetic acid level in the vinegar.
Sinus Congestion
Apple cider vinegar helps to break up and reduce mucous in your body, helping to clear your sinuses. It also has antibacterial properties, making it useful for infections.
Sore Throat
The antibacterial properties in apple cider vinegar may be useful for sore throats as well. Gargle with a mixture of about one-third cup of apple cider vinegar mixed with warm water as needed.
Digestion and Acid Reflux
Acid reflux typically results from having too little acid in your stomach. You can easily improve the acid content of your stomach by taking one tablespoon of raw unfiltered apple cider vinegar in a large glass of water daily. The pectin in apple cider vinegar may also help to soothe intestinal spasms.
Skin Irritations
Apple cider vinegar works for a variety of skin ailments, from bug bites to poison ivy to sunburn. You can either apply it directly to the irritated area or try soaking in a bath with about one cup of vinegar added.
Energy Boost
Apple cider vinegar contains potassium and enzymes to help banish fatigue. Plus, its amino acids may help prevent the buildup of lactic acid in your body, further preventing fatigue.
