Water, bottled, generic

Bottled water carries no Nutrient Density Score, since it is entirely calorie-free and, unlike almost every other item in the Beverages category, contributes no protein, fat, carbohydrate, or fiber worth measuring.

It's consumed simply for hydration, poured from bottle to glass throughout the day, with a typical serving measured here at one fluid ounce (30 g), though most people drink several times that per sitting. Sodium is minimal at 2 mg per 100 g, and there is no sugar in the listed values, which makes it the plainest baseline in a category otherwise filled with sweetened sodas, juices, and flavored waters.
