Examples: Cheese (generic), for the average person, i.e., overweight pre-diabetic or factors for heart disease: Bad! But: Cheese for a person who is low/deficient in calcium (a very important nutrient) and or at a healthy BMI? Quite likely good -- dairy in general is associated with health benefits.
Sardines (canned, in olive oil), for the average person? Probably a poor score here. But: A person with a healthy body weight who needs omega-3 fatty acids (correlated with 15%-18% lower all-cause mortality!! https://www.nature.com/articles/s41467-021-22370-2), sardines are very healthy option.
Potatoes, baked. For the average person these are probably iffy; the avg overweight person may struggle to achieve a healthy weight if eating these to caloric excess, with butter/cheese/bacon etc. But this food will likely be labeled as a "vegetable" with a good score. For a healthy/active person with a healthy BMI, potatoes are fine, esp if the person gets exercise. (Low carb dieters may disagree, but baked potatoes in moderation for a healthy person should not be controversial.)
