Re: When is the best time of day to eat blueberries?
Well, I guess if you do want to be safe, I probably would separate them. Your topic sparked my interest and I noticed that all the papers I was able to find found only dairy products did this, not all sources of protein. So this would imply at least that it is the types of proteins contained in dairy products. I guess from a biochemical standpoint, it could be argued that the proteins in milk could compete for the cell membrane. On the other hand, they'd have to release sometime, and then the antioxidant would be free to enter, just a delayed absorption.
One other possibility is that if you are using pastuerized milk, the enzymes are gone. Now normally in lipid-soluble vitamins, such as Vitamin E, it is widely accepted that a lipid is required to enter the cell membrane. However, one area that is grossly neglected is enzyme technology. In some cases, enzymes would help absorption even better than fats! So if the enzymes are gone, you won't get any help at least from the milk. There are also numerous chemicals that cows are fed and who in the world knows how these affect absorption of our vitamins/minerals.
To play it safe, I'd separate the times. But don't worry too much, the blueberries will digest pretty rapidly, so not too much time would be required. I'd go blueberries first, wait maybe 30 minutes and then drink your milk. I guess putting them in cereal if this belief is followed would be out.
