Food Additives and Hyperactivity–Again!

I thought we were done with food additives as a cause of hyperactivity in kids years ago, but here it comes again. A new and well controlled study in The Lancet, funded by the British Food Standards Agency (which presumably has no axe to grind), reports higher average levels of hyperactivity in young children drinking a mix of sodium benzoate (a preservative) and food colors. For why these results surprise me, take a look at the Wikipedia entry for the Feingold Diet, the additive-free diet developed decades ago to prevent hyperactivity in kids. The first Wikipedia paragraph says it all:

“The Feingold diet is a food elimination program developed by Ben F. Feingold, MD to treat hyperactivity. It eliminates a number of artificial colors and artificial flavors, aspartame, three petroleum-based preservatives, and (at least initially) certain salicylates. There has been much debate about the efficacy of this program. Some mainstream medical practitioners deny that it is of any value, while other medical practitioners, as well as many people living with ADHD and parents of children with ADHD, claim that it is effective in the management of ADHD as well as a number of other behavioral, physical and neurological conditions. The debate has continued for more than 30 years, involving not only consumers and physicians, but scientists, politicians, and the pharmaceutical and food industries.”

After this excellent beginning, the article gets so muddled that the editors warn: “The neutrality of this article is disputed.” Indeed. Until now, my reading of the science was that the more carefully the studies were done, the less benefit they showed. Even the best studies showed wide individual differences–most kids were unaffected by removing additives but a small percentage seemed to get better. This made the studies especially subject to biased interpretation.

This new study seems well done but again shows large individual differences, so expect the debates to continue. In the meantime, it’s good to remember that color additives go into processed foods to cover up flaws and make them look attractive. Kids don’t need to be eating highly processed foods. The study is another good reason to feed kids plenty of fruits, vegetables, and other minimally processed foods.

Here’s what today’s New York Times has to say about the study.

Kellogg’s Nutrition at a Glance?

I get sent lots of food company press releases and this one is just in. Kellogg’s is announcing its new nutrition labeling for cereal boxes. Useful? Or even more confusing?

Sugar Free?

The FDA is fed up with products claiming to be sugar free but not mentioning that they still have lots of calories. So the agency has decided not to let food companies get away with this anymore. Its latest “guidance” warns companies that if they say a product is “sugar-free,” it better be low in calories too. It’s great to see the FDA trying to do something about misleading health claims. Doesn’t this poor, beleaguered agency deserve a cheer for this one!

Scientific American Special Issue on Feast or Famine

My article, “Eating Made Simple,” appears in the September issue of Scientific American along with a podcast. Enjoy! The journal’s website also has an excerpt from What to Eat–Chapter 5 on the produce section: “Genetically Modified, Irradiated, and Politicized.” Enjoy that too!

Hannaford’s Stars Get Results

Hannaford, the supermarket chain in the Northeast, today reports the one-year results of its Guiding Stars program. This, you may recall, puts zero, one, two, or three stars on foods in the store, depending on how the products meet some rather rigorous nutrition standards. When the program started a year ago, less than one-fourth of 27,000 foods in the store qualified for even one star (when the criteria are independent, products endorsed as healthy by their makers do not qualify). Did the program encourage people to choose products with stars over those without them? It did! Take a look at the results and see if you think this approach is worthwhile. Hannaford does not reveal its nutritional criteria for awarding stars because of patent issues. I think it should. If the program works, other stores might be encouraged to try something similar. And here’s what the New York Times has to say about it.

Coming Soon to Your Local Grocery: Country-of-Origin Labeling for Meat

Thanks to Lisa Young, author of The Portion Teller, for passing along a neat article from the Detroit News about country-of-origin-labeling of meat. Check out the map showing the global nature of our meat supply. Unless Congress delays these labels yet again, we’ll be seeing them at meat counters starting next year. And won’t that be interesting? Stay tuned.

Oh no! Flooded Organic Farms!

Jim Harkness of the Institute for Agriculture and Trade Policy in Minneapolis sends this link to a video showing what the floods have done to organic farms in the Midwest. Nobody ever said farming was easy, but this seems especially tragic.

More Research on Marketing to Kids

Once researchers started to look, the results just pour in. Thanks to Margo Wootan of CSPI for send this new study from the journal, Pediatrics. It finds virtually all ads for food products on kids’ TV to be for the junkier ones. No surprise here; these are the profitable products. How many more of these studies do we need? Really, isn’t it high time for a few restrictions? How’s this for a starting position? No marketing of foods to kids. Period.
