Could humans evolve/adapt to the modern "western" diet (a lot of sugar, carbs, all that other stuff)?

Is it possible for humans, overtime, to evolve/adapt to the modern "western" diet? Such as the consumption of a lot of sugar, fats, carbs, etc. through stuff like soft drinks, desserts, fast food, and all that other stuff. Will our bodies change to accommodate that diet better by changing to make that stuff less harmful in the amounts we eat?
