EDIT:
Forgot to mention. COVID seems to have been causing a rise in Type-I diabetes cases in non-juveniles =/
While one can increase their chances of developing diabetes later in life with poor diet choices (called Type 2), many people are born with diabetes. (Type 1)
It's wild how diabetes is an epidemic in so many places.

Big box stores push refined and processed foods that contain excessive amounts of sugar these days. They have sugary snacks and drinks in the checkout lines. They carry very few products without added sugars; try to find a bread, pasta sauce, or soup without crazy amounts of sugar.
It's not entirely their fault, but Walmart has demonstrated in the last 40 years that they can compel manufacturers to just about whatever they want. If they wanted, they could push for the reduction or elimination of excess sugars in processed foods.
But then again, there wouldn't be as large a market for Walmart brand insulin if they did that.
So… you think Walmart sells processed foods because it will increase their insulin sales? Not because they’re extremely popular high margin sales items?
90-95% of people who have diabetes are type 2. It's largely a lifestyle disease, even when you include those who have autoimmune issues.
