How Vinegar Can Damage Your Health

Health effects of vinegar

Look up vinegar on the internet and you will see an abundance of praises for its benefits. But is there any truth behind the accolades? What about the long-term health effects of vinegar? Do the benefits outweigh the risks?

What Is Vinegar?

Vinegar is an alcoholic liquid that has been allowed to ferment and sour.

The basic component of vinegar (including apple cider vinegar) is diluted acetic acid, which is a toxic waste product in the human body.

Does the Consumption of Vinegar Offer Health Benefits?

Yes, there are some studies and anecdotal evidence that show that vinegar offers some health benefits. But the consumption of vinegar also carries with it some health risks.

Health Risks Associated with the Consumption of Vinegar

Acetic acid – the main component of vinegar – is an irritant to the stomach and causes a loss of the protective mucus in the intestinal tract, setting the stage for ulcers, gastritis, vitamin deficiencies (especially vitamin B12), and/or infection with Heliobacter pylori. In fact, vinegar is one of the 3 most common dietary causes of gastritis in the U.S. today, along with aspirin and alcohol.

Vinegar interferes with digestion, and consequently the body receives less nourishment and impurities enter the bloodstream.

Vinegar also promotes changes in the stomach lining cells, which can increase the risk of stomach cancer.  The consumption of vinegar is also now recognized as a factor in the development of cancer of the upper gastrointestinal tract.

Acetic acid stimulates the thyroid gland to pull phosphorous from the adrenal glands to negate the effects of acetic acid in the system. Depleted phosphorous results in impaired function of the adrenal glands.

The use of vinegar has been shown to be harmful to the liver and to the kidneys.

Vinegar is also an irritant to the central nervous system.

Regular consumption of vinegar can cause low potassium levels and lower bone density.

Studies have shown that vinegar contributes to Candida overgrowth.

Fermented foods, such as vinegar, contain high amounts of tyramine. Tyramine can contribute to high blood pressure, joint pain, urticaria, irritable bowel syndrome, and headaches.

Are the Benefits Worth the Risks?

Since all of the benefits of vinegar can be easily obtained through a healthy diet and lifestyle, there is no reason to consume vinegar and increase risk of cancer, poor digestion, impaired function of the adrenal glands, liver, and kidneys, and the other health issues associated with including vinegar in the diet.

Does apple cider vinegar help with weight loss?

There are literally hundreds of “get-thin-quick plans” on the market promising dramatic weight loss in a short amount of time. The average person wanting to try a new diet won’t be faced with a shortage of options.

In a culture attracted to “the quick fix”, it can be enticing to substitute healthful eating with “miracle diets” or “special weight loss foods” that promise effortless results. Sometimes we may be tempted to think that there is an easier method of weight loss than a healthy lifestyle. However, most fad diets have been shown to be not only unhealthful, but sometimes dangerous as well. And while some diet schemes may help you lose a few pounds at the beginning, statistics show that most actually encourage weight gain in the long term.

The apple cider vinegar diet is an example of a fad diet. Despite the hype, there is simply no evidence to support any of these claims. On the contrary, there is an abundance of evidence demonstrating vinegar’s negative contribution to health.

Following a healthy, whole-food, plant-based diet is not only a safe method of weight loss, but a healthy and long-lasting one as well.

What about apple cider vinegar?

Apple cider vinegar is still vinegar and has all the negative health characteristics that regular vinegar has.
