CARROTS

Carrots are crammed with betacarotene, a pigment the body converts into vitamin A — essential for healthy skin and mucous membranes, night vision and maintenance of the immune system. Just one medium carrot can provide you with more than 100 per cent of your recommended daily intake of vitamin A.

Eat it: Slice lengthways, toss with olive oil, dried thyme and salt, roast in the oven for 20 minutes, then mix with rice or quinoa, chickpeas, toasted pecans and a squeeze of lemon juice.
