Drinking plenty of non-alcoholic liquid each day is an often overlooked part of a well-balanced diet. A minimum of 8 glasses is the ideal. If possible, these should not all be tea or coffee, as these are stimulants and diuretics, which cause the body to lose liquids, taking with them water-soluble vitamins. Water is the best choice.
Other good choices are fruit or herb teas, fruit juices—diluted with water, if preferred—or reduced-fat or fat-free milk (full-fat milk for very young children). Fizzy sugary or acidic drinks such as cola are more likely to damage tooth enamel than other drinks.
