It covers drinks in the Fluids section! I’ve copied and pasted it below. I mostly drink boiled water, but I have to have my morning tea and after dinner coffee 
“Aim for 3 litres (zero calorie) fluids per day. There is an allowance of 200 mls semi-skimmed milk for teas/coffees, or as a drink. If you prefer not to use milk, have a 150-175g pot of low fat yoghurt instead. The remaining 2.8 litres as water, teas, herbal infusions, coffee. Try to avoid sweetened ‘diet’ drinks.
Tip: Flavour water (including sparkling water) with lemon, cucumber, or orange and keep a jug in the fridge to keep nice and cold.”
