9 Things to Stop Worrying About

 

Feed a cold, starve a fever

The old wives’ tale has been a staple since the 1500s when a dictionary master wrote, “Fasting is a great remedie of feuer.”

The Truth: “Colds and fevers are generally caused by viruses that tend to last seven to 10 days, no matter what you do,” says Rachel Vreeman, MD, a fellow in Children’s Health Services Research at the Indiana University School of Medicine in Indianapolis. “And there is no good evidence that diet has any effect on a cold or fever. Even if you don’t feel like eating, you still need fluids, so put a priority on those.” If you’re congested, the fluids will keep mucus thinner and help loosen chest and nasal congestion.

Fresh is always better than frozen

Ever since scientists honed in on the benefits of antioxidants, the mantra has been “eat more fresh fruits and veggies”—implying that frozen is second-rate.

The Truth: “Frozen can be just as good as fresh because the fruits and vegetables are harvested at the peak of their nutritional content, taken to a plant, and frozen on the spot, locking in nutrients,” Beeson says. And, unless it’s picked and sold the same day, produce at farmers’ markets—though still nutritious—may lose nutrients because of heat, air, and water.

Eggs raise your cholesterol

In the 1960s and 1970s, scientists linked blood cholesterol with heart disease—and eggs (high in cholesterol) were banished to the chicken house.

The Truth: Newer studies have found that saturated and trans fats in a person’s diet, not dietary cholesterol, are more likely to raise heart disease risk. And, at 213 milligrams of cholesterol, one egg slips under the American Heart Association’s recommendation of no more than 300 milligrams a day. “Eggs offer lean protein and vitamins A and D, and they’re inexpensive and convenient,” Beeson says.

Get cold, and you’ll catch a cold

It must be true because your mother always said so. Right?

The Truth: Mom was wrong. “Chilling doesn’t hurt your immunity, unless you’re so cold that your body defenses are destroyed—and that only occurs during hypothermia,” Vreeman says. “And you can’t get a cold unless you’re exposed to a virus that causes a cold.” The reason people get more colds in the winter isn’t because of the temperature, but it may be a result of being cooped up in closed spaces and exposed to the spray of cold viruses.

Your lipstick could make you sick

In 2007, an environmentalist group, the Campaign for Safe Cosmetics, had 33 lipsticks tested for lead. Although there’s no lead limit for lipstick, one-third of the tubes had more than the limit allowed for candy.

The Truth: “The reality is that lead is in almost everything,” says Michael Thun, MD, head of epidemiological research for the American Cancer Society. “It’s all around us. But the risk from lead in lipstick is extremely small.” In fact, lead poisoning is most commonly caused by other environmental factors—pipes and paint in older homes, for instance.
