HUMANS are programmed to eat more in winter, so say those in the know.

HUMANS are programmed to eat more in winter, so say those in the know.

This is the body's way of stocking up fat reserves to keep internal organs from freezing and to prepare for periods of food scarcity.

If this theory is true, it would explain why so many of us go on a "see food" diet in winter. You know, the diet that makes you put in your mouth whatever food you see in front of you.

But this gluttonous attitude should not amount to piling on blubber just to keep yourself warm. A few additions to your shopping can keep you warm and healthy this winter.

Foods rich in vitamin D - which your body might be deprived of by being cooped up indoors - will keep you warm and ensure that the body performs its functions at its best. These include oily fish such as tuna and salmon, milk and eggs.

Use herbs and spices such as peppercorns, chilli, cinnamon and ginger in your cooking for wholesome flavour and medicinal properties. Replenish the body with warm fluids such as soups and herbal tea.

Exercise is just as important in winter. Take a brisk walk in the sun and enjoy the crisp air - your body will thank you for it.
