EWG publishes new food list

"FOOD SAFETY: CLEANSING OPTIONS”

CLEAN 15
Onions, Avocado, Sweet Corn, Pineapple, Mango, Sweet Peas, Asparagus, Kiwi, Cabbage, Eggplant, Cantaloupe, Watermelon, Grapefruit, Sweet Potato, Honeydew Melon

DIRTY DOZEN (BUY ORGANIC)
Celery, Peaches, Strawberries, Apples, Blueberries, Nectarines, Bell Peppers, Spinach, Kale, Cherries, Potatoes, Grapes (Imported)

Why Should You Care About Pesticides?
The growing consensus among scientists is that small doses of pesticides and other chemicals can cause lasting damage to human health, especially during fetal development and early childhood.
Scientists now know enough about the long-term consequences of ingesting these powerful chemicals to advise that we minimize our consumption of pesticides.

What’s the Difference?
EWG research has found that people who eat five fruits and vegetables a day from the Dirty Dozen list consume an average of 10 pesticides a day. Those who eat from the 15 least contaminated conventionally-grown fruits and vegetables ingest fewer than 2 pesticides daily. The Guide helps consumers make informed choices to lower their dietary pesticide load.

Will Washing and Peeling Help?
The data used to create these lists is based on produce tested as it is typically eaten (meaning washed, rinsed or peeled, depending on the type of produce). Rinsing reduces but does not eliminate pesticides. Peeling helps, but valuable nutrients often go down the drain with the skin. The best approach: eat a varied diet, rinse all produce and buy organic when possible.

How Was This Guide Developed?
EWG analysts have developed the Guide based on data from nearly 96,000 tests for pesticide residues in produce conducted between 2000 and 2008 and collected by the U.S. Department of Agriculture and the U.S. Food and Drug Administration. You can find a detailed description of the criteria EWG used to develop these rankings and

Selecting Fruits and Vegetables for Your Best Health

From the BBC comes a good report on the ins and outs of the whys and wherefores of eating a varied diet, especially when it comes to fruits and vegetables. Get more information here and here.

'Pick the right veg' for health
Obvious choices of fruit and vegetables are not necessarily the healthiest, say researchers.

According to US experts, making simple swaps like eating sweet potatoes instead of carrots and papaya rather than oranges could make a difference.

Foods, like raspberries, watercress and kale, are richer in phytonutrients which may help prevent disease, they told a US meeting.

UK nutritionists said a balanced diet is essential to good health.

The British Nutrition Foundation warned that relying on eating a few select food types to boost health was ill-advised and said there was no such thing as a "superfood".

Experts recommend five portions a day of fruit and veg in a healthy diet.

Plant foods are known to contain "phytonutrient" chemicals that can protect the heart and arteries and prevent cancers.

But the most popular varieties may not be the best, according to US researchers.

They analysed data from US health surveys of people's dietary habits to look at the most common sources of phytonutrients.

They found that for 10 of the 14 phytonutrients studied, a single food type accounted for two-thirds or more of an individual's consumption, regardless of how much fruit and veg they ate overall.

Carrots were the most common source of beta-carotene, oranges and orange juice the most common source of beta-cryptoxanthin, spinach the most common source of lutein/zeaxanthin, strawberries the most common source of ellagic acid and mustard the biggest provider of isothiocyanates.

However, for each of these phytonutrients there was a richer food source available.

Richer foods

Switching from carrots to sweet potatoes would nearly double beta-carotene intake, say the researchers.

Similarly papaya contains 15 times more beta-cryptoxanthin than oranges, while kale has three times more lutein/zeaxanthin than spinach.

Raspberries have three times more ellagic acid than strawberries and one cup of watercress contains as much isothiocyanate as four teaspoonfuls of mustard.

Study leader Keith Randolph, who is a technology strategist for the supplement company Nutrilite, said: "These data highlight the importance of not only the quantity but also the significant impact the quality and variety of the fruits and vegetables you eat can have on your health."

Dr Emma Williams of the British Nutrition Foundation said: "They are right that some foods are richer sources of phytonutrients.

"But at the end of the day, to be healthy you need to make sure you have a varied and balanced diet.

"No one food can give you everything you need."

The findings were presented at the 2010 Experimental Biology conference in Anaheim, California.
