How to Wash Fruits and Vegetables



How to Wash Fruits and Vegetables

This will make you shudder: Studies conducted at Tennessee State University found that the vegetable bin is the dirtiest part of the refrigerator. And no wonder: Fresh from the grocery store, a standard head of romaine lettuce can have as many as 2 million bacteria per gram, plus yeast, mold, and assorted germ carriers.

Swearing off fresh produce is clearly not the answer. What is? Washing it with plain, room-temperature tap water. In some cases, doing so cuts bacteria by as much as 98 percent. So stow the fancy veggie washes and sprays, and after your next trip to the store or farmers' market, ask yourself these four questions, then follow our advice.

Does it have edible skin?

Think: apples, peaches, tomatoes, zucchini, peppers

Scrub under running water for 30 to 60 seconds. "Running water helps remove most bacteria," explains Brendan Niemira, Ph.D., lead scientist with the USDA Agricultural Research Service. Scrubbing with a vegetable brush or your fingers (to avoid bruising softer fruit like peaches) will help eliminate stubborn hangers-on.

Does it have a peel?

Think: melons, oranges, and yes, even bananas

Use a vegetable brush or an unused toothbrush on the peel under running water for 30 to 60 seconds. The bristles can reach into crevices on textured skins, where dirt hides. Why bother washing it if you're not biting into it? "Microbes from the fruit's skin can spread to the flesh when you touch it with your hands or a knife," says Alfred Bushway, Ph.D., a professor of food science at the University of Maine. And even if you washed your hands, the 20 people who handled that fruit before you may not have.

Does it grow in a bunch?

Think: berries, grapes

Cut off stalks and stems where dirt can hide, dump the fruit into a colander, and hose down with your sink's spray nozzle for at least 60 seconds. (A too-brief rinse will redistribute the dirt, not remove it, according to tests conducted by Alan Johnson at Northeast Laboratories in Connecticut.) Patting the fruit dry with paper towels will further cut down on bacteria, says Sandria Godwin, Ph.D., a professor at Tennessee State University.

Is it leafy?

Think: spinach, lettuce (even prewashed mixes)

Discard the outer leaves and run the rest under cold water for 30 to 60 seconds. Dry with a salad spinner or blot with paper towels. Prewashed mixes are FDA-approved for eating straight from the container, but Godwin discovered "huge differences" in how well various brands of bagged greens were cleaned. So don't wait for a recall—take a few minutes to wash it yourself.

The Olympic Diet of Michael Phelps!

By Kathleen M. Zelman, MPH, RD, LD WebMD Health News Questions and answers about the high-calorie diet that fuels the Olympic swimmer's championship performance. Aug. 13, 2008 -- His body may resemble the trim, athletic figure of Michelangelo's statue of David, but the diet of Michael Phelps sure doesn't sound like the stuff of champions. The U.S. Olympic swimmer told ESPN that he eats roughly 8,000-10,000 calories a day, including "lots of pizza and pasta." In addition to stuffing down carbs, he's said that he routinely eats foods like fried egg sandwiches. So exactly how do all those calories help fuel the most decorated Olympic athlete in history? Here are some questions and answers about the Michael Phelps diet. How can Michael Phelps eat 10,000 calories a day and still be so lean? There is no doubt he packs away a ton of food, but it is unlikely that he actually eats that many calories a day, an expert believes. University of Pittsburgh Director of Sports...

Soy Products Can Reduce Sperm Counts!

By: Heather Hajek Published: Friday, 25 July 2008 www.healthnews.com C alling all men who want to become fathers! Soy products may reduce a man's sperm count. Based on a recent study, men who consume soy products may have lower sperm counts than those who don't. The study was based on a small group of men who visited the Massachusetts General Hospital Fertility Center from 2000 to 2006. Even though the study found that some of the men who ate soy products on a regular basis had lower sperm counts, the researchers conducting the study are not saying that soy products were the cause of the lower sperm concentrations. The men who had soy products in their diets recorded lower sperm counts than those that didn't, but their counts were still within the normal range. Researchers don't deny that during the study men who consumed soy products had lower sperm counts, but they want people to realize there are other factors other than soy products that may have played a role in th...

Biggest explosion!

Thu Feb 19, 3:58 pm ET WASHINGTON (AFP) – The US space agency's Fermi telescope has detected a massive explosion in space which scientists say is the biggest gamma-ray burst ever detected, a report published Thursday in Science Express said. The spectacular blast, which occurred in September in the Carina constellation, produced energies ranging from 3,000 to more than five billion times that of visible light, astrophysicists said. "Visible light has an energy range of between two and three electron volts and these were in the millions to billions of electron volts," astrophysicist Frank Reddy of US space agency NASA told AFP. "If you think about it in terms of energy, X-rays are more energetic because they penetrate matter. These things don't stop for anything -- they just bore through and that's why we can see them from enormous distances," Reddy said. A team led by Jochen Greiner of Germany's Max Planck Institute for Extraterrestrial Physics deter...
