If a study claimed that eating unlimited tacos every day was bad, as it found detrimental effects to 50% of the population, yes, I would be interested in knowing if being in the other 50% meant it wasn't bad you for.
If processed foods(, or alcohol, or meat, or carbs, or whatever) have 25% increased negative outcomes for overweight people, but only 2% increased negative outcomes for non-overweight people, that significantly changes the calculus.
I don't understand how you don't understand why you'd want to know that. It's practically equivalent to avoiding peanuts because other people have peanut allergies.
