Dr. Greene’s take on preventing allergies…

Many parents still hear the advice that it’s better to wait to introduce fish to babies until their first birthdays, or even their second. I disagree! And a growing body of evidence suggests that starting fish between 6 and 12 months results in fewer allergies – both in the short run and by the time they become teens.

Giving babies and toddlers fish a couple of times a week, or even a couple of times a month, may be one of the best tips for preventing allergies.

And perhaps today’s babies and toddlers eating less fish is even one of the reasons allergies have been going up in kids overall, potentially from a decrease of omega-3 fats in the diet. This includes food allergies, pet allergies, and pollen allergies.

Babies’ regularly eating fish before the first birthday could also result in less eczema at age 4. Who doesn’t want better skin?

Another study last year found a window from 6-12 months (earlier or later wasn’t as good), where if babies were introduced to eating fish, they were less likely to have asthma or wheezing symptoms later in preschool. Who doesn’t want to breathe easier?

The longest study I’ve seen yet followed thousands of children from their first birthdays all the way until they were 12 years old. It will appear in the June 2013 American Journal of Clinical Nutrition. Those kids who were already enjoying fish at least twice a month by the first birthday were less likely to have allergies every year thereafter.

My favorite fish for kids is wild (or sockeye, or Alaska, or Pacific) salmon, fresh or even canned, twice a week. You can prepare the pouched or canned salmon as if it were tuna. But check out the NRDC pocket seafood guide for lots of great suggestions. And here are some some DrGreene.com recipes.

Bon appetit!

Bonus tip: Reduced tobacco exposure and increased eating of oily fish during pregnancy and early childhood are all linked to fewer allergies.
