A spoonful or two of vinegar a day may boost your levels of good cholesterol.
Researchers believe that people who consume apple cider vinegar for eight weeks will have improved levels of good or HDL cholesterol compared with those given a placebo.
A clinical trial, currently underway in Minnesota in the U.S., has been looking at 120 people, half of whom have had the vinegar while the others are being given a placebo containing a 2 per cent balsamic vinegar solution in water.
Apple cider vinegar — a common kitchen remedy for arthritis and gout — has already been shown to lower blood sugar levels and reduce appetite.
A separate study based on animals with diabetes, has already shown that apple cider vinegar lowered levels of bad cholesterol and improved good cholesterol.
Increasing Calcium Absorption
If there is one thing vinegar fans, marketers, alternative therapists, and scientists alike can agree on, it's that vinegar is high in acetic acid. And acetic acid, like other acids, can increase the body's absorption of important minerals from the foods we eat. Therefore, including apple cider vinegar in meals or possibly even drinking a mild tonic of vinegar and water (up to a tablespoon in a glass of water) just before or with meals might improve your body's ability to absorb the essential minerals locked in foods.
Vinegar may be especially useful to women, who generally have a hard time getting all the calcium their bodies need to keep bones strong and prevent the debilitating, bone-thinning disease osteoporosis. Although dietary calcium is most abundant in dairy products such as milk, many women (and men) suffer from a condition called lactose intolerance that makes it difficult or impossible for them to digest the sugar in milk. As a result, they may suffer uncomfortable gastrointestinal symptoms, such as cramping and diarrhea, when they consume dairy products. These women must often look elsewhere to fulfill their dietary calcium needs.
Dark, leafy greens are good sources of calcium, but some of these greens also contain compounds that inhibit calcium absorption. Fortunately for dairy-deprived women (and even those who do drink milk), a few splashes of vinegar or a tangy vinaigrette on their greens may very well allow them to absorb more valuable calcium. Don't you wish all medications were so tasty?
Controlling Blood Sugar Levels
Vinegar has recently won attention for its potential to help people with type 2 diabetes get a better handle on their disease. Improved control could help them delay or prevent such complications as blindness, impotence, and a loss of feeling in the extremities that may necessitate amputation. Also, because people with diabetes are at increased risk for other serious health problems, such as heart disease, improved control of their diabetes could potentially help to ward off these associated conditions, as well.
With type 2 diabetes, the body's cells become resistant to the action of the hormone insulin. The body normally releases insulin into the bloodstream in response to a meal. Insulin's job is to help the body's cells take in the glucose, or sugar, from the carbohydrates in food, so they can use it for energy. But when the body's cells become insulin resistant, the sugar from food begins to build up in the blood, even while the cells themselves are starving for it. (High levels of insulin tend to build up in the blood, too, because the body releases more and more insulin to try to transport the large amounts of sugar out of the bloodstream and into the cells.)
Over time, high levels of blood sugar can damage nerves throughout the body and otherwise cause irreversible harm. So one major goal of diabetes treatment is to normalize blood sugar levels and keep them in a healthier range as much as possible. And that's where vinegar appears to help.
It seems that vinegar may be able to inactivate some of the digestive enzymes that break the carbohydrates from food into sugar, thus slowing the absorption of sugar from a meal into the bloodstream. Slowing sugar absorption gives the insulin-resistant body more time to pull sugar out of the blood and thus helps prevent the blood sugar level from rising so high. Blunting the sudden jump in blood sugar that would usually occur after a meal also lessens the amount of insulin the body needs to release at one time to remove the sugar from the blood.
A study cited in 2004 in the American Diabetes Association's publication Diabetes Care indicates that vinegar holds real promise for helping people with diabetes. In the study, 21 people with either type 2 diabetes or insulin resistance (a prediabetes condition) and eight control subjects were each given a solution containing five teaspoons of vinegar, five teaspoons of water, and one teaspoon of saccharin two minutes before ingesting a high-carbohydrate meal. The blood sugar and insulin levels of the participants were measured before the meal and 30 minutes and 60 minutes after the meal.
Vinegar increased overall insulin sensitivity 34 percent in the study participants who were insulin-resistant and 19 percent in those with type 2 diabetes. That means their bodies actually became more receptive to insulin, allowing the hormone to do its job of getting sugar out of the blood and into the cells. Both blood sugar and blood insulin levels were lower than normal in the insulin-resistant participants, which is more good news. Surprisingly, the control group (who had neither diabetes nor a prediabetic condition but were given the vinegar solution) also experienced a reduction in insulin levels in the blood. These findings are significant because, in addition to the nerve damage caused by perpetually elevated blood sugar levels, several chronic conditions, including heart disease, have been linked to excess insulin in the blood over prolonged periods of time.
More studies certainly need to be done to confirm the extent of vinegar's benefits for type 2 diabetes patients and those at risk of developing this increasingly common disease. But for now, people with type 2 diabetes might be wise to talk with their doctors or dietitians about consuming more vinegar.
