Sure, but even that cherry looks a whole lot more like the rest of the numbers I've found than the one grandparent comment offered.
The study you cite only examines the costs for cardiometabolic disease, not all healthcare costs. And then says that suboptimal diet is responsible for 18% of that specific category.
"18% of the costs of the one category most closely linked" and "5-10% of all healthcare costs" seem like plausibly compatible measures. Whereas the grandparent comment's claim remains out of synch with those by an order of magnitude.
Yes, 20% of the cost "from heart disease, stroke, and diabetes", which is significantly less than 20% of the total. (The press release has less ambiguous wording: "18 percent of all heart disease, stroke and type 2 diabetes costs in the country").
