I don't know that you need a megaphone, but it's time again to talk to the Food and Drug Administration. The FDA recently decided that trans-fats, the former darlings of highly processed foods, cannot be "generally recognized as safe". They are proposing a ban on the use of trans-fats in foods manufactured and sold in the United States. This seems reasonable for a substance that isn't recognized as safe. Or as actual food.
But, of course, Big Food and Big Ag are likely to fight this new rule and they have lots of money to bring to the fight. So the FDA needs to hear from citizens-who-are-not-corporations. The public comment period for this rule change lasts for 60 days from the announcement, which came early last week. The Center for Science in the Public Interest is providing a template for those wanting to lodge a comment on the regulation.
