3 How much should you drink?

Current guidelines in the Eatwell Guide are six to eight glasses of fluid daily. This equates to 2000 ml for men and 1600 ml for women from drinks alone. This includes children 14 years old and above. Don’t forget that 20–30% of your fluid intake is from food.

Figure 3 shows some average amounts in different containers.
