Avo go and aid your health.

From May to September supermarkets and greengrocers will be selling some of the best avocados you can buy, which come to the UK after being ripened by the South African sun.

Avocados are free from cholesterol and solid fat, the kind which leads to the hardening of the arteries, and are a great source of monounsaturated fats ( the kind which helps lower cholesterol.

Recent studies have also shown avocados to be a good source of lutein, which protects against eye disease such as cataracts and age-related macular degeneration.

Avocados are richer in potassium than bananas, and this is an essential mineral for maintaining nerve and muscle functions.

Other superfoods include beans, blueberries, broccoli, oats, salmon, soya, tomatoes, walnuts and yoghurt.
