Live Cleaner, Eat Cleaner By Friday

Houseplants can help, too. Her top 10 air cleaners include Boston ferns, ficus, bamboo palms, English ivy and rubber plants.

Tuesday: Pick purer produce. While eating more fruits and vegetables is on everybody’s radar these days, these good-for-you foods are often your No. 1 source of pesticides, says Cynthia Curl, Ph.D., an assistant professor in Boise State University's School of Allied Health Sciences. An easy way to protect yourself is to buy organic: Her research, based on a sample of 4,500 people in six U.S. cities, has shown that those who consume conventionally grown produce have nine times higher exposure to common pesticides than people who eat mostly organic.

“That doesn’t mean that people should think ‘I’ll only eat organic, or no produce at all,’” she tells Life Reimagined. “Conventional produce is very good for you. And we still don’t know how much actual health risk comes from those higher levels of pesticides.” (Though a recent study from the University of Oxford in the U.K. has shown that pesticide exposure increases the risk of Type 2 diabetes by nearly 60 percent.)

Curl’s advice? Buy organic for the produce named most vulnerable by the EWG’s Dirty Dozen, which ranks strawberries, apples, nectarines, peaches and celery as the most likely to chemical-laden. And she recommends following Consumer Reports produce rankings to help make smarter decisions.

Wednesday: Clear the air at work. All the contaminants in your air at home can occur at work, too, says Claudio. If you think your job is sucking the energy out of you, the solution may be as simple as improved office ventilation. A Harvard University study found that people who work in “greener” offices (those with lower levels of VOCs) are 61 percent sharper in cognitive measures. (Researchers evaluated how sharp workers’ thinking was after working six straight days, 9 to 5, in either a green or conventional office.)

A few plants, a HEPA air filter and open windows can help. So can giving your smoking colleagues a wider berth. Third-hand smoke, the residue that clings to surfaces and clothing even after the cigarette is extinguished, is especially potent when it combines with ozone and nitrous acid, which are common indoor pollutants. Experts at the University of California’s Berkeley Lab say these chemicals can linger for as long as two months after smokers have moved on, and they’re toxic enough to damage our DNA.

Thursday: Minimize the meat you eat. For years, nutritionists had been warning people to ease off processed meats, including bacon, hot dogs and cold cuts, because of nitrates and other chemicals. There are cautions about red meat’s impact on heart health, too. Recently, the World Health Organization went even further, classifying processed meats as a Group 1 carcinogen, saying that consuming any red meat probably raises the risk of colorectal, pancreatic and prostate cancer.

The risk, while real, is much smaller than the risk posed by cigarette smoke or alcohol. If you limit meat consumption to three ounces or less a day (a serving about the size of a bar of soap, or a hamburger patty the size of a hockey puck), one large Japanese study found there’s no increased risk of mortality from heart disease.

Friday: Breathe better in your car. While it would be great if everyone could spend less time in cars to reduce exposure to air pollution, that’s not practical for many people. But research from the University of Southern California’s Keck School of Medicine has shown that keeping the windows closed and switching the car’s ventilation to “recirculate” has a big impact. In a typical car (about seven years old), doing so cut in-car pollution for very small particles from 80 percent to 20 percent, and reduced the number of large-particle pollutants from 70 percent to 30 percent. Particle pollution is linked to such health problems as heart disease, respiratory illness, cancer and premature death.
