Superfoods: fruit and veg

Superfoods: avocados

Although people are sometimes wary of avocados because of their high fat content, most of the fat is monounsaturated. Avocados are an excellent source of vitamin E, which helps keep the heart healthy by preventing the oxidation of LDL ‘bad’ cholesterol. Also, one small avocado provides over half the RDA of vitamin B6 – essential for a healthy nervous system and anyone on the Pill or antibiotics, while low levels have been linked with depression and chronic fatigue syndrome.

Small, knobbly Hass avocados have the best flavour. Add to salads and sandwiches, or mash with low-fat yoghurt and a dash of chilli to make guacamole. Half an avocado counts as one of your five daily servings of fruit and veg.
