Unless you’ve been living under a rock, chances are you’ve heard about the much-touted health benefits of vinegar—in particular, apple cider vinegar. The ancient condiment—the earliest known use of vinegar dates back more than 10,000 years and has been used as both food and medicine—is enjoying a real resurgence lately. “Cleansing diets and juicing have become so popular, and I think that’s created the recent buzz around vinegar,” says Bonnie Taub-Dix, registered dietician and author of “Read It Before You Eat It.”
As with any trend, it’s easy to get lost in the hype and start believing that vinegar is a miracle medicine (it isn’t). In fact, one of the most popular claims—that drinking a small amount of apple cider vinegar before a meal helps curb appetite and burn fat—has little scientific support, according to the Mayo Clinic.
So we did some digging and found some valid, science-back benefits to vinegar that are worth sharing. In fact, research shows that vinegars contain antioxidants, which slow premature aging and reduce the risk of cancer, for example.
Here are a few more ways vinegar can give your health a boost:
Vinegar improves blood sugar levels. Drinking apple cider vinegar before a high-carbohydrate meal improves insulin sensitivity—slowing the rate of blood sugar levels rising—in people who are insulin resistant (a prediabetes condition) or have type 2 diabetes, according to a 2004 study. The researchers note that vinegar may possess physiological effects similar to the anti-diabetes medications Acarbose and Metformin.
It protects your heart health. Balsamic vinegar prevents the oxidation of low-density lipoprotein (LDL), which is believed to contribute to atherosclerosis—a condition in which plaque builds up in the arteries, blocking blood flow and in some cases, eventually leading to a heart attack or stroke, according to a 2010 study.
Substituting in vinegar can help you lose weight. The condiment can easily replace unhealthy fats—namely, in commercial salad dressing. “What I love to do is take a favorite dressing, even blue cheese, which is rich and high in calories, and I dilute it down with vinegar,” suggests Taub-Dix, who splits commercial dressing into two bottles and fills up the remaining half with vinegar. “The vinegar adds a delicious flavor and cuts calories in half. Or I make my own dressing at home with balsamic or champagne vinegar.”
It kills bacteria. Vinegar is thought to have antibacterial properties that can help fight the infection behind a sore throat. The acidity decreases the pH of tissue, which helps prevent bacteria from growing on its surface. In addition, a 2014 study even found that vinegar’s ingredient, acetic acid, which gives vinegar its tart flavor and strong odor, acts as a non-toxic disinfectant against drug-resistant tuberculosis (TB) bacteria.
Vinegar may help reduce the risk of cancer. Vinegars are a rich source of polyphenols, compounds synthesized by plants to fight oxidative stress. According to 2006 research, consuming polyphenols enhances antioxidant protection and reduces cancer risk.
Bottom line: Vinegar can be beneficial in several ways, but it isn’t a magical cure-all and doesn’t replace common sense behaviors like eating a healthy, balanced diet, notes Taub-Dix. Plus, vinegar is an acid, so going overboard with it or not rinsing out your mouth after consuming it can erode tooth enamel over time.

Are You Allergic to the Sun?

Although die-hard sun worshipers continue to oil up to better catch the sun's tanning rays, most Americans choose to slather on sunscreen instead. Sunscreen can help protect them from most of the harmful effects of ultraviolet light, but it will do little for certain sun-sensitive individuals. These would-be sun seekers wind up with an itchy, bumpy rash that is sometimes called "sun poisoning" even if they're wearing SPF 50.

"Sun poisoning" is really an allergic reaction to the sun that occurs when skin is exposed to sunlight for the first time in the early spring, or during a winter vacation. While people with light skin are most susceptible to sunburn, sun allergy affects people of all skin colors.

If people with sun allergy venture to the beach at all, you can probably find them in a floppy hat, under an umbrella. Or, at least, that's where they should be. Below, Henry W. Lim, MD, chair of the department of dermatology at Henry Ford Hospital in Detroit, Michigan, talks about how to prevent and treat allergic reactions to the sun, as well as rashes triggered by sunscreen ingredients.
Can someone have a sun allergy?
There are certain skin reactions to the sun that have nothing to do with sunscreen or other external factors, which we call an intrinsic type of photodermatosis. People with photodermatosis develop skin rashes following exposure to the sun. Polymorphous light eruption is the most common type of photodermatosis. It is most likely due to an abnormal immune system reaction to the sun. Polymorphous light eruption occurs in approximately 10 to 20 percent of otherwise healthy individuals, so it is a relatively common condition.

Then there is another group of people who develop what they think is a sun allergy because of medications that they have ingested or agents that they have applied, including sunscreen. These people develop an irritant reaction, which is a rash or a tingling, itchy sensation on the skin. The chances of getting a true allergic reaction to sunscreen are actually very low.

What are the symptoms?
People usually develop reactions within a few hours of sun exposure. The typical scenario would be that they get exposed to the sun during the day, and then at the end of the day they start noticing the development of red bumps or blisters in the exposed area. It tends to be somewhat itchy. The polymorphous light eruption produces a rash that looks more like hives or insect bites. Sometimes people have no symptoms. If the reaction is untreated, it usually lasts for a few days, or up to two weeks. Then it would go away by itself.

Does it get worse or better with repeated exposure?
It tends to occur most commonly in the springtime in a temperate climate when people first start getting sun exposure. Typically as the season progresses, the person becomes less sensitive to developing this reaction; the thought is that the skin adjusts to this effect of the sun. But any kind of sudden and relatively intense exposure to the sun would bring this up. A typical scenario in the winter is when patients from Northern climates go to the Caribbean or Hawaii, for example, for their winter vacation.
Can someone develop sun allergy at any time in their life?
It can occur at any time in someone's life, but typically it occurs in people in their 20s and their 30s. And it can occur in people of all skin types. So not only Caucasians, but also Asians, Latinos and black people can develop photosensitivity. Is sun allergy ever a sign of an underlying condition?
There have been some reports of an association with lupus and with thyroid problems, but those are exceptions rather than the rule. We do evaluate patients for those conditions on a routine basis. We ask them questions and take some blood tests, if necessary. But the vast majority of patients are perfectly healthy otherwise. What kind of ultraviolet light causes the reaction?
It's usually UVB light, but it could be UVA also. So it varies from person to person and one would have to test for it. The testing is usually conducted in a clinic setting. We can use light sources that emit predominantly UVB or light sources that emit predominantly UVA to see which one would induce the lesion.
That would help to guide the treatment somewhat. Realistically, however, the testing is not that widely available because only specialized photodermatology centers would be able to perform it, and it is not 100 percent positive in all patients.

What medications might increase risk of sun allergy?
There's a whole long list of oral medications that can make skin more sensitive to sunlight. This includes some forms of antibiotics such as tetracyclines. Certain diuretics, or water pills, also frequently make the skin more sun-sensitive. My suggestion usually is that if people have sun allergies, they ask their primary care physician about their medications' side effects.

How are allergic reactions to the sun treated? 

Beyond staying in the shade, wearing protective clothing and using sunscreen, we recommend topical corticosteroids to treat the rash. Some are over-the-counter, such as hydrocortisone, but that's not very potent. The more severe reactions require a prescription cortisone cream or ointment. For very severe reactions, we have to use oral cortisone to bring down the inflammation.
If we know that someone has polymorphous light eruption every summer, we may give them ultraviolet light treatment as a way to desensitize the skin in the spring. It's almost like you're going to an allergist for allergy shots. By exposing your skin to ultraviolet light, your system gets used to it. Usually we do about 15 treatments.

The second approach to treat a rash is to use a medication called Plaquenil (hydroxychloroquine), which is an antimalarial agent that has been used for various skin conditions; it works quite well for polymorphous light eruption.
