PERK UP YOUR POTASSIUM

Innocent Coconut Water, 500ml, £2.49, ocado.com Per 100ml: Calories, 14; saturated fat, 0g; sugar, 2.2g; salt, 0.07g CLAIM: ‘100 per cent coconut water. A source of potassium.’ Still drink that’s ‘the perfect thirst-quencher’. EXPERT VERDICT: Potassium is a mineral important for regulating blood pressure and fluid levels in the body. Coconut water may be a source of potassium (you’ll get 25 per cent of your daily needs in a 250ml serving) — but most of us get adequate amounts in our diets, from foods such as bananas and cooked broccoli. Your potassium levels can drop briefly if you pass a lot of urine (for example, those taking high doses of diuretics for high blood pressure), have persistent diarrhoea or sweat excessively — but it’s still fairly uncommon. That said, this is a nice, natural drink, with nothing added. TASTE: Subtly sweet, silky coconut flavour. 9/10
