Just finished: a compilation of all the studies I can find on the food dyes used in the US and their connection with behavior and health.
This project was created to help the California Office of Environmental Health Hazard Assessment (OEHHA) in their upcoming deliberations over whether to reconsider a warning label on food dyes. But I want to make the information also available to you if you want to see it for your own information, or to share with family, friends, doctor, etc.
(There is surprisingly little out there on those colorings used in toothpaste, dental disclosure tabs, soaps, and cosmetics — Red 30, Red 28, etc.)
One surprising finding is that there is a lot of work going on now discovering medical uses for some of these food dyes — as treatments for diseases resistant to other treatment, such as Parkinson’s, Alzheimer’s, Spinal Cord Injury, Dengue Fever, Zika Flu, Yellow Fever, etc.
Another interesting finding is that a number of studies are not asking whether the dyes are harmful; no indeed, they know that. Some researchers have been discovering items to protect you against harm if you accidentally ate them!! Spoiler alert — add garlic and ginger tea and saffron to your diet. How much? Your guess is as good as mine; they haven’t got that far yet, but when you have no choice, just do the best you can.
