I saw this product this week, it creates an app showing how your body reacts to certain foods. Whilst its not being marketed as anything to do with diabetes, its not a big leap to see that its quite likely that the worst foods for us to eat, might show up in this way.
I have pre-ordered one - due for release in August 2017
Looks interesting.
I already know the foods worst for me those laden with carbohydrates I can differentiate between them by using my blood glucose meter how would this device be of more benefit to me.
IMHO it is absolutely a sales gimmick (I can't spell ****) where diabetics are concerned. If it can't give me my blood sugar levels then it is of no use to me.
I hope that's an accurate estimate. As you say, an interesting device, I'd like to find out more. What happens in the gut has a knock on affect with the way the Krebs cycle works (or doesn't), so it could be useful.
