> hamburgers and milkshakes don’t give you heart disease and cancer

They absolutely do, particularly if you're getting most of your calories from them. If evidence-based medicine doesn't convince you, uh, hamburgers and supermarket milk tends to be processed.

They absolutely do not, unless you’re getting too many calories.

Individual foods are—with some exceptions—neither bad for you nor good for you. A healthy diet can occasionally include doughnuts, and milkshakes. Your overall diet is what matters.

Sure, they are not mercury-level toxic. However, these recommendations are for people who consume way too much of these dishes, and it's a safe assumption that this is the case for a significant part of the population.

Sure. We’re saying roughly the same thing. For most Americans, hamburgers cause heart disease because we don’t exercise enough or eat enough plants. If you’re backpacking twenty miles a day, sure, eat whatever, you won’t suffer inflammation or obesity from it. (Though you may run nutritional deficiencies. And you’re building bad habits for when your activity necessarily tapers off.)
