Prioriser la bouffe bio qui fait une différence

Not all organic products are considered equal. According to Sonya Lunder, a senior analyst at the research and advocacy organization Environmental Working Group, some fruits and vegetables absorb more pesticides than others.

Shoppers who can only afford to buy some organic food should splurge on the organic version of what she calls the "dirty dozen" in produce: peaches, apples, bell peppers, celery, nectarines, strawberries, cherries, kale, lettuce, imported grapes, carrots and pears. These fruits and vegetables absorb more chemicals than others. Onions, avocados, sweet corn and pineapples are among the Environmental Working Group's "Clean 15" fruits and vegetables, which absorb the least amount of pesticides. For shoppers who selectively buy organic, Lunder suggests splurging on organic meat, cheese, milk and baby food. "Chemicals accumulate in fat," she says. "So products like meat or cheese, which contain large portions of animal fat, may have accumulated antibiotics or pesticides." She also recommends buying organic baby food because

infants eat large amounts of a few types of food. What about products made with grapes and grains, such as wine, beer and bread products? Save your money. Organic pasta, oatmeal, bread and such are made from grains that have been grown without pesticides for three years. But the conventional versions don't have as many chemicals as, say, peaches, so cost-conscious consumers may not want to splurge on those. As for beverages, organic wines lack sulfites, which vintners use to prevent the wines from going sour. Wines without sulfites have a greater chance of spoilage, which may not outweigh whatever benefits come from avoiding the preservatives.
