Vinegar as a dieting aid?

It’s long been an old wives’ tale that vinegar can help you lose weight – supposedly because vinegar and oil don’t mix. Now it seems there may be some truth to this after all – at least as far as the weight loss goes.

Researchers in Japan have found that acetic acid (the scientific name for the active ingredient found in vinegar) given to mice fed on a high fat diet resulted in the mice developing significantly less body fat than other mice.

The mice given the vinegar had up to 10% less body fat that the other mice. This result provides some evidence to the theory that acetic acid can “turn on” fat burning genes. These genes in turn produce proteins that are involved in breaking down fats, preventing the fat from accumulating in the body.
About the study

The study is reported in the Journal of Agricultural and Food Chemistry. The mice were given acetic acid for a period of 6 weeks. The study found that this reduced the uptake of body fat without changing eating habits (i.e. the acetic acid did not make them eat less) or their muscle weight, implying that the reduction in weight was due to less fat in the body.

Dr Chris says:

“Well this is fascinating, but don’t forget ‘mice ain’t men’. Clearly there is something interesting here but obviously more work needs to be done to understand how the vinegar might affect fat absorption, and then this needs to be applied to humans to see if it still holds true. However, whilst we are all waiting we can enjoy the taste of vinegar while thinking about how it might be helping us to keep off the pounds – so here is some more useful information about vinegar, including a recipe idea you might want to try tonight.”
What is vinegar?

Vinegar is made from liquids that contain alcohol, typically wine but also cider, beer, fruit juices and other such products. The liquid is fermented, producing acetic acid from its alcohol (ethanol).
What is vinegar used for?


Vinegar is mainly used as a food condiment to add flavouring, as a medium for pickling and preserving other foods and as a component of sauces and salad dressings (where it is often mixed with oil).
Vinegar and medicine

Vinegar has been used in traditional health treatments, but generally there is no good scientific evidence for these treatments; however there have been studies that have suggested vinegar might play a part in lowering cholesterol and blood pressure. However these results have not yet been demonstrated in humans. It has also been used in the past as a treatment for diabetics, however this is no longer the case due to improved medicines.

Other uses:

Vinegar can be used as a cleaning agent in some circumstances. For instance, it can clean glass and other hard surfaces and is used as an ingredient in some household cleaning agents.
Ideas for healthy eating with vinegar

Vinegar helps to make excellent salad dressing. Why not combine the benefits of vinegar, olive oil, vegetables, eggs and fish by making a Salad Nicoise? Simply combine cooked eggs, tuna, anchovies, boiled new potatoes, green beans and tomatoes on a bed of salad leaves, and drizzle with a vinaigrette of your choice (combine olive oil, vinegar, Dijon mustard and freshly ground pepper for instance). Simple, delicious and healthy.

Can red wine treat diabetes?

A new study has revealed that red wine is packed with anti-diabetic compounds – so does that mean it could be a potential source of treatment?

Alois Jungbauer and colleagues at the University of Natural Resources and Life Sciences in Vienna, Austria, tested 10 reds and two whites to find out how strongly the wines bound to a protein called PPAR-gamma, which is targeted by the anti-diabetic drug rosiglitazone.


PPAR-gamma regulates the uptake of glucose in fat cells. Rosiglitazone targets PPAR-gamma in fat cells to make them more sensitive to insulin and improve the uptake of glucose.

The team found that the white wines had low binding affinities, but all the reds bound readily: the tendency of 100 millilitres of red wine – about half a glass – to bind to PPAR-gamma is up to four times as strong as the same tendency in the daily dose of rosiglitazone.

“It”s incredible. It”s a really high activity. At first we were worried it was an artefact, but then we identified the compounds responsible in the wine,” New Scientist quoted Jungbauer as saying.

However, not all the anti-diabetic compounds may be absorbed by the body. Plus, it also contains ethanol, which will add to your calories.

Veronique Cheynier at University of Montpellier agreed, saying that most polyphenols do not pass through the digestive tract unchanged and may not be absorbed at all.

The next step for Jungbauer and his team will be to measure the metabolic effects of the wine compounds on healthy people.

The study appears in Food and Function.
