One of the questions Iím most commonly asked as a doctor, and one I ask myself often as a mom, is: should I buy organic foods?
Itís not an easy question to answer, because there is a lot
we donít know about the health benefits of organic foodsóor the risks of
conventional ones. It would be an easier decision if organic foods werenít more expensiveóbut they are,
and for lots of families buying all organic just isnít an option. This week,
the American Academy of Pediatrics came out with a clinical report to help us
figure out what to do as we stand in those grocery aisles.
Itís not an easy question to answer, because there is a lot we donít know about the health benefits of organic foodsóor the risks of conventional ones. It would be an easier decision if organic foods werenít more expensiveóbut they are, and for lots of families buying all organic just isnít an option. This week, the American Academy of Pediatrics came out with a clinical report to help us figure out what to do as we stand in those grocery aisles.
Hereís what they said:
1. Itís not clear that organic foods are more nutritious. They might be, but so far there isnít the scientific evidence to prove itóin part because there are so many variables like humidity, soil quality or how the food is harvested that affect nutrition. If you are making your decision purely from a nutrition standpoint, organic doesn't seem to be necessary.
2. Organic produce has fewer pesticides. Nobody is arguing this pointóthis is part of what defines organic foods. What is tricky here is that we donít know if the amount of pesticides in conventional foods is dangerous or not. There are studies that suggest that exposure to pesticides during pregnancy can lead to learning and behavior problems in childrenóin general, itís babies and children we worry most about. They get a higher dose because they are smalleróand chemicals can be dangerous for their developing brains and bodies. But the truth is, we just donít know whatís safe at any age.
But before you cancel your cable so you can pay for all organic produce, not all produce is the same when it comes to pesticides. Conventionally grown corn on the cob and onions, for example, donít have much at allóbut apples and grapes do. Thereís some great information available from the Environmental Working Group (including a great app called Dirty Dozen) that can help you decide when buying organic makes the most sense.
3. Organic meats have fewer resistant bacteria in them. Conventional farms give animals antibiotics to make them bigger. And whenever you use antibiotics a lot, you kill off the weaker bacteria and leave the resistant ones, like MRSA (methicillin-resistant staphylococcus aureus), that are causing all sorts of really tough infections these days.
There isnít really much risk of catching one of these infections from making burgers, especially if you cook the meat well and wash your hands. But by buying meats from companies that donít use antibiotics you can help fight the superbug problem. And thatís a good thing.
4. You donít need to buy organic milk (or organic infant formulas). Pesticides really arenít a problem in milk, so you donít need to worry about that. What most people worry about is hormonesóbut it turns out that we donít really need to worry about that, either. Yes, cows are given bovine (cow) growth hormone, and it gets into their milkóbut besides the fact that it gets broken down by pasteurization and our digestive systems, itís a cow hormone; it doesnít affect humans. Cows are also given estrogen, but the amount that gets into milk is too small to cause any trouble (another reason to drink lowfat or skim milk: the higher the fat, the higher the amount of estrogen).
5. Organic farming is better for the environment and for sustaining our resources. It leaves a better earth for our children, and thatís important. By buying organic foods, we encourage more farmers to use organic methods for making our foodóand to find cheaper ways to do it, something the AAP says is absolutely possible if we set our minds to it.
In making the organic-or-not decision at the grocery store, remember that the most important thing is to eat a healthy diet full of fruits, vegetables, whole grains, low-fat dairy and lean meatsówhether or not they are organic. Having five servings a day of conventional produce is healthier than one serving a day of organic produce. Thereís also way more to overall healthólike exercise, getting enough sleep and immunizations. As with everything in lifeóand especially in parentingóitís crucial to keep some perspective.
