Agreed. The base rate of getting type 2 diabetes is 11%. So if you increase your consumption of sugar sweetened beverages to one serving per day above the average, your chance of getting diabetes is now ~13%. You increase your absolute risk by 2%. So the average marginal healthcare cost is $85,200*.02 = ~$1700. I'm not sure how he goes from 1 serving per day to 2555 per decade. I would assume it would be ~3650 servings. So for every soda you drink, it would add $0.47 in additional medical costs. But the study also controls for adiposity since people with higher body fat are more likely to get diabetes and are also more likely to drink sugar sweetened beverages. If you control for that then each drink adds $0.21 in additional medical costs.
