Eggs May Increase Heart Disease Risk

If you think you’re doing yourself a favor by ordering an omelet at brunch, think again. Eating an excessive amount of eggs may increase the risk of heart disease and stroke—even for people without traditional risk factors—according to a new study from the New England Journal of Medicine. Even more surprising: the reason why eggs may be dangerous. It was previously thought that the cholesterol in eggs promoted heart disease, but this research shows that there may be other factors at play.

Turns out, a metabolite found in egg yolks called lecithin may be to blame. When lecithin is digested, it breaks down into its different components, including the chemical choline. When intestinal bacteria metabolizes choline, it releases a substance that the liver then converts into a compound called trimethylamine N-oxide (aka TMAO), explains lead study researcher Stanley Hazen, MD, PhD, chairman of the department of cellular and molecular medicine at the Cleveland Clinic Lerner Research Institute. TMAO accelerates the rate at which plaque and cholesterol collect in the arteries, increasing the risk of heart disease and stroke.

These findings come just two weeks after the same group of researchers reported a link between carnitine (found in beef and some energy drinks) and heart attack risk. “Both studies show a potential new way for identifying patients at risk for heart disease,” says Hazen.

So should you ditch eggs altogether? Not necessarily. More studies are needed to confirm the results. In the meantime, moderation is key, says Hazen. He suggests cutting back on fatty, cholesterol-laden foods that contain chemicals that convert to TMAO. “Forego whole eggs,” he suggests. “Since the yolk is the only source of choline in an egg, egg whites are the safest bet—and are also an excellent source of low-fat protein.”

Skin Cancer May Increase Your Risk of OTHER Cancers

Need some extra motivation to slather on the sunscreen every a.m.? People who have had non-melanoma skin cancer may have an increased risk of developing another type of cancer in the future, according to a new study published in the journal PLOS Medicine. Seeing as how skin cancer is the most prevalent form of cancer in the United States—and non-melanoma is the most common type—these findings are pretty alarming.

Several previous studies have shown a link between non-melanoma skin cancer and other types of cancer, says lead study author Jiali Han, PhD, of Brigham and Women’s Hospital and Harvard Medical School. Researchers at the hospital analyzed data from two long-term studies in the U.S. and found that women with a history of non-melanoma skin cancer had a 26 percent higher chance of developing a subsequent cancer. (Men had a 15 percent higher risk.) For women specifically, the researchers found a significant link between a history of non-melanoma skin cancer and, later, lung cancer, breast cancer, and melanoma.

Han calls the association modest and points out that it’s not necessarily a causal one. More research is needed to determine why the association exists. And while this just adds to the humongo list of reasons why skin cancer is scary, remember: It’s also one of the most preventable kinds of cancer.

Learn your risk for developing the disease and what you may not know about it. And don’t forget—ever—to spread on sunscreen before you leave home. It may take a couple of extra minutes, but it’s so worth it.

The Food That Slashes Your Diabetes Risk

Next to peanut butter and almond milk, walnuts don’t get much love—but there’s a new reason to stock your nut bowl with them: Eating walnuts could reduce your risk of developing Type 2 diabetes, according to a new study published in the Journal of Nutrition.

Researchers analyzed data collected by the Nurses’ Health Study (NHS) and NHS II, two separate decade-long studies that tracked the diets and health records of 138,000 women. While all of the participants were disease-free at the beginning of the study, 5,930 of them developed Type 2 diabetes during the 10-year span. Women who ate at least eight ounces of walnuts a month (that’s a little more than two cups of walnut halves) had a 24 percent lower risk of developing Type 2 diabetes than the women who rarely ate walnuts. Better yet: Walnut-eaters were also leaner than the women who ate the nuts only on occasion.

While researchers didn’t examine exactly how walnuts fight diabetes, they suspect it has to do with polyunsaturated fatty acids (PUFAs). Walnuts are full of them—and that’s a good thing. After all, past research has shown that PUFAs may reduce insulin sensitivity, which helps reduce the risk of Type 2 diabetes, says lead study author An Pan, PhD, research associate in the department of nutrition at the Harvard School of Public Health. And like other tree nuts, walnuts contain protein, plant sterols, fiber, and antioxidants, which may also play a role in fighting Type 2 diabetes, he says.

A healthy lifestyle may also be what’s helping nut-eaters fend off disease, says Pan. People who consume nuts tend to eat better in general, exercise more, weigh less, and have lower body mass indexes (BMI), he says. Worried about the calorie content of nuts? Don’t be: Previous studies suggest that eating nuts doesn’t lead to weight gain—especially when you choose them over meats or unhealthy foods, says Pan.

So go ahead: Hit up the nut bowl for walnuts a few times a week. Or try one of these tasty recipes, all of which call for the diabetes-fighting food:

Do You Know Your Diabetes Risk?

Have a couple of spare minutes today? Resist the urge to spend them on Cute Overload looking at puppy pics, and use them to find out your chances of developing type-2 diabetes instead. It’s the American Diabetes Association’s Alert Day, which was created to encourage people to take the ADA’s Diabetes Risk Test.

Diabetes affects almost 26 million people in the U.S., or 8.3 percent of the population, according to the Centers for Disease Control and Prevention. For adults in the U.S., it’s the leading cause of kidney failure, non-traumatic lower-limb amputations, and new cases of blindness. It’s also a major cause of heart disease and stroke.

In 2010, one in three people in the U.S. aged 20 or older had prediabetes, meaning that their blood glucose levels were abnormally high and that they faced a higher risk of getting diabetes. What’s worse: Only 11 percent of the people with prediabetes knew they had the condition, according to a new report from the CDC. In many cases, people with prediabetes don’t experience any symptoms. “That’s why we really advocate that people who are at risk get screening bloodwork done,” says Brandy Panunti, MD, chair of endocrinology at the Ochsner Medical Center in New Orleans.

People who are overweight and sedentary have a higher possibility of developing diabetes, as do African Americans, Hispanic people, Native Americans, Asian Americans, and Pacific Islanders. Having a family history of diabetes, having had gestational diabetes, or having given birth to a baby over nine pounds can also increase your risk.

Even if you are on your way to developing diabetes, you can make lifestyle changes to seriously turn things around, says Panunti. The key, of course, is knowing whether you’re at risk. Head to the American Diabetes Association’s website or Facebook page, or call 1-800-DIABETES (1-800-342-2383) to take the Diabetes Risk Test—a quick series of questions about you and your lifestyle—for free. “It’s easy to take,” says Lurelean B. Gaines, the ADA’s president of health care and education. “It’s a matter of minutes.”

You should also speak with a doctor about your odds of developing diabetes, especially if the test results indicate that you’re at risk.

Done with the test? OK, now you can check out those adorable animal pictures.

The Checklist That Slashes Your Cancer Risk

Checklists can help you tackle everything from grocery shopping to party planning to packing for your vacation—and now there’s one to help you seriously slash your cancer risk, too: People who follow six or more items on the American Heart Association’s list of seven heart-healthy guidelines lower their cancer risk by 51 percent, according to a new study.

So what’s on the checklist exactly? The American Heart Association calls these recommendations “The Simple 7”:

  • -Being physically active
  • -Keeping a healthy weight
  • -Eating a healthy diet
  • -Maintaining healthy cholesterol levels
  • -Keeping blood pressure down
  • -Regulating blood sugar levels
  • -Not smoking

Researchers looked at the health records of 13,253 men and women who took part in the Atherosclerosis Risk In Communities (ARIC) study, which was conducted from 1987 to 2006. They also reviewed participants’ cancer registries and hospital records from those years and found that the more items from the checklist that the participants stuck to, the lower their risk for cancer. Compared to those who followed none of the recommendations, people who met three of the guidelines still had a 25 percent lower risk of cancer. Those who met six or seven had a 51 percent lower risk.

If you have to choose one item to check off first, Neica Goldberg, MD, director of Women’s Heart Program at New York University’s Langone Medical Center, recommends you make it smoking. “That has a huge impact on decreasing cancer risk,” she says. That said, you’ll see the best results if you work toward checking off all of the items on the list. “They’re really pieces that work together,” says Goldberg.

Getting started
While the steps you can take to follow some of the items on the checklist are pretty straightforward (you know how to stay active, keep your weight healthy, and eat well), others aren’t as obvious (how do you even check your blood sugar levels?!).

To ensure you’re keeping your cholesterol in check, you have to know what it is: You should get your first cholesterol test in your 20s, says Goldberg. Your total cholesterol should be less than 200, your HDL, or “good” cholesterol, should be greater than 50, and your LDL, or “bad” cholesterol, should be less than 130, she says. After your initial test, you can wait another five years before your next one if you’re an otherwise healthy person and have good lifestyle habits, she says.

As for your blood pressure, be sure to get it checked out every time you see your primary care doctor. It should be less than or equal to 120 over 80.

A blood glucose test checks the level of sugar in your body and is used to screen for diabetes, according to the Cleveland Clinic. If you’re eating healthy and working out, you probably don’t need one—but your doctor can let you know if you have any warning signs that make it a good idea to get tested. Here’s what’s involved: You won’t eat for eight hours, and then a doctor will take a blood sample to determine your fasting blood glucose level. The number should be below 100. Any higher, and you’re in the pre-diabetes or diabetes range, in which case your doctor may prescribe you medications or insulin.

Possible saboteurs
Certain habits can undermine your efforts to check off every item on the list. Two big issues common among young women, says Goldberg: drinking too much and popping certain pills like Accutane. Boozing can actually weaken your heart muscle and enlarge it. Alcohol is also toxic to your ticker, says Goldberg. Her recommendation: Stick to one drink a day at most. As for the pills you’re taking, ask your doctor if a drug will raise your triglycerides or cholesterol level before he writes you a prescription (since this can put you at risk for heart disease).

The Mistake that Puts You at Risk for HPV

You wouldn’t stop running a 5K a quarter of a mile before crossing the finish line—or stop having sex just moments before orgasming. Yet 10 percent of women who start the HPV vaccination series never finish it, rendering it less effective, according to new research from the University of Texas Medical Branch.

Researchers examined data from the National Health Interview Survey, which tracks more than 27,000 adults in the U.S. They found that, as of 2010 (the most recent year for which stats were available at the start of the study), more than 75 percent of women ages 18 to 26 had not begun the HPV vaccination series. What’s more, 10 percent of the women who had received at least one shot weren’t administered all three doses. Since it’s not yet known how much protection girls and women receive from just one or two doses of an HPV vaccine, it’s crucial to finish out the series to reap the full benefits.

Introduced seven years ago, the human papillomavirus (HPV) vaccine series prevents infection from the four strains of HPV that are most likely to cause cervical cancer and genital warts. The vaccine series also helps prevent cancers of the vulva and the vagina and is approved for the prevention of anal cancers in both men and women. HPV is the most common sexually transmitted infection in the U.S. At least half of all sexually active men and women contract genital HPV at some point in their lives, according to the Centers for Disease Control and Prevention.

The problem: HPV vaccines are administered on a three-dose schedule, with the second shot administered one to two months after the first dose and the third shot administered six months after the first dose. Because of this, completion rates are an issue, says lead author Abbey Berenson, MD, director of the University of Texas Medical Branch’s Center for Interdisciplinary Research in Women’s Health.

“Most people do not typically need to go to the doctor three times in six months,” says Berenson. “They forget their follow-up appointments or do not make them a priority.”

If you’ve missed one or two HPV shots, it’s not too late to finish the series. According to previous research from the University of Washington in Seattle, delaying doses of the vaccine won’t diminish the series’ effectiveness. What may? Skipping a dose altogether, says Berenson.

The CDC’s Advisory Committee on Immunization Practices recommends the vaccine to women up to age 26 who did not get one or all of the doses when they were younger. (The best option for females is getting vaccinated between the ages of 11 and 12, but most of us were already older than that when the vaccine first became available.)

Planing to see your doc for the doses you missed? Two brands of the vaccine are approved for use in women (Cervarix and Gardasil). If possible, it’s best to get all of your doses from the same brand—so try to figure out which one you already received before you book your appointment. It’s also a good idea to go ahead and schedule any follow-up appointments now. Once they’re on your calendar, they’ll be harder to miss.

The Drink That Lowers Your Risk of Diabetes

 
Worried about your blood glucose levels? Have some tea. In a study of 42 countries, researchers found that higher black tea consumption was associated with a lower risk of type 2 diabetes.

Researchers looked at countrywide sales of black tea and compared that data with rates of respiratory, infectious, and cardiovascular diseases, in addition to cancer and diabetes, as reported by the World Health Organization’s World Health Survey.

The research, published online in the journal BMJ Open, found that on average, a population that consumes double the amount of black tea compared to another country about 25 percent fewer cases of diabetes. There was no association with black tea consumption and the other four health indicators.

Swiss research agency Data Mining International and Unilever, the makers of Lipton tea, carried out the study.

“This study is very interesting because it confirms a lot of different, small studies on the health benefits of black tea,” says Ariel Beresniak, Ph.D., chief executive officer of Data Mining International. Previous studies have pointed to evidence that black tea has antidiabetes properties, including that it improves pancreatic function in glucose-intolerant rats.

The Drink That Boosts Your Stroke Risk


You already know that drinking sugary beverages is bad for your waistline. Now there’s evidence than it can lead to serious trouble in your head, too. Turns out drinking soda regularly can seriously increase your risk of stroke, according to a study from Japan.

Researchers tracked the soft drink consumption of 39,786 Japanese men and women over 18 years, and found that women who reported drinking about one sugary soda per day were 83 percent more likely to suffer an ischemic stroke than women who consumed soda infrequently or not at all. More troubling: Among women who reduced their soda intake during the first three to nine years of the study, their risk of stroke didn’t diminish. Meaning: Your soda habit can be deadly for years in the future, even if you quit cold turkey today.

Ischemic stroke occurs when clogged arteries prevent blood from getting to the brain. In high consumption, sugar can contribute to blood vessel damage and plaque build-up that narrows or completely blocks arteries. However, soda could pack a one-two punch: First with the sugar, and second with the caffeine, which can potentially lead to an increased risk of high blood pressure—another risk factor for stroke, says James Conners, M.D, stroke neurologist at Rush University Medical Center in Chicaco.

More research is needed to determine the culprit of the study’s findings—particularly because researchers found that the association between sugary drink intake and stroke risk was insignificant among men. “We’d also need to look at the other habits of people drinking high-sugar soft drinks on a daily basis. People who don’t drink soft drinks might have better diets and exercise more frequently,” Connors says.  

According to the National Stroke Association, as many as 80 percent of strokes can be prevented by lifestyle changes. And if you already stay away from soda, you’re not off the hook. Moderate your intake of all sugary drinks to reduce your risk of stroke. Want to know what sugary drinks to avoid (or totally cut out of your life)? Check our chart, below:

Are You At Risk of Messing Up Your Birth Control?

Feeling sad or anxious? Your reproductive health might be at risk. Women with symptoms of depression or stress are significantly less likely to use birth control consistently, according to a study recently presented at the American Public Health Association’s annual meeting. Inconsistent use of birth control can lead to greater risk of unwanted pregnancy and contracting STIs.

Researchers assessed the mental health of 689 18-to-19-year-old women and then asked them to report their sexual activity and birth control usage every week for two and a half years. While the study participants used contraceptives consistently 72 percent of the time, women with moderate-to-severe symptoms of depression were 47 percent less likely to use birth control consistently, and women with moderate-to-severe symptoms of stress were 69 percent less likely to use contraceptive consistently. The reasons given: 31 percent said they forgot, 21 percent didn’t have their contraceptive method available, 6 percent weren’t happy with the method, another 6 percent said their partner didn’t want to use the method, and 4 percent weren’t trying to avoid pregnancy. The remaining 33 percent didn’t specify a reason for not using protection.

Your mental health impacts how well you take care of your physical—and reproductive—health, says Kelli Stidham Hall, PhD, research investigator at the Population Studies Center at the University of Michigan’s Institute for Social Research, who presented the study findings. “Feeling sad, down, in despair, and worthless can impact general thought processing and can interfere with your ability to make decisions,” she says. That includes decisions about contraceptive use, and it’s especially true when it comes to birth control that requires actual effort—like remembering to take a pill at the same time every day. Stidham Hall points out that symptoms of depression, like lack of energy or interest, or feeling moderate-to-severe stress, which can make everything you do feel overwhelming, can be major roadblocks to appropriate birth control use.

For women who suffer from stress or depression (either occasionally or as a diagnosis), the best birth control options are those that are easiest to use, Stidham Hall says. She recommends long-acting reversible contraceptives (LARCs), such as intrauterine devices (IUDs) and subdermal implants.

“For women who don’t want to deal with taking daily pills, or using a condom every time, LARCs can be ideal, and allow these women to tend to other issues that need more attention,” she says. LARCs require no thought at all once they’re implanted, and have been shown to have over 99 percent effectiveness in protecting against unwanted pregnancy. Check out this birth control chart to compare their cost and effectiveness against other options, and make your gynecologist aware of your mental state so he or she can help identify the contraception that’s best for you.

Drink THIS to Cut Your Cancer Risk

Jonesing for a caffeine fix? Reach for some tea. A new study published in the American Journal of Clinical Nutrition suggests that sipping tea regularly could slash your risk of certain digestive system cancers by up to 29%.

The Shanghai Women’s Health Study tracked the tea consumption and cancer rates of more than 69,000 non-drinking, non-smoking, middle-aged and older Japanese women during an 11-year span. Regular tea consumption, defined as at least three times a week for more than six months, was associated with a 17% reduced risk of all digestive cancers combined. “We can conclude that women who drink tea regularly may have a lower risk of developing some digestive system cancers, particularly colorectal and stomach/esophageal cancer,” says lead study author Sarah Nechuta, Ph.D., MPH, assistant professor of medicine at Vanderbilt University.

Better yet: The study found that drinking more tea contributed to an even lower risk. Women who sipped two to three cups a day had a 21% lower risk of digestive system cancers overall. And those who drank tea regularly for 20 years or more were 27% percent less likely to develop any digestive system cancer, and 29% less likely to develop colorectal cancer, in particular. “We observed the strongest reduction among long-term tea drinkers,” says Nechuta.

And while this study was observational (i.e., lifestyle factors such as diet and exercise were not controlled), and researchers didn’t investigate tea temperature, strength, or whether food or supplements containing tea extracts would have similar effects, the study did have implications for the most effective type of cancer-fighting tea, according to Nechuta. “As most women in our study drank green tea, our results suggest drinking green tea is associated with reduced risk of digestive system cancers,” she says.

So drink more green tea, but don’t stop there. Here are 12 more ways to reduce your cancer risk.
