Ward off seasonal colds with our top healthy eating tips:

1. It's boring, but you need to eat healthily: fruit and vegetables are packed with immune-boosting properties like vitamin C and beta-carotene.

2. Eat more lean fish and meat, milk, cheese, eggs, cereals, pulses and wholemeal bread, as protein is required to produce antibodies, which fight infection and illness. Avoid sugar as it weakens your immune system.

3. Try taking supplements such as echinacea, an immune-stimulating herb or garlic, which is rich in allicin (powerful antibiotic and anti-fungal compound) or Siberian ginseng and B6 to stimulate resistance to stress. Vitamin C also helps to boost your immune system.
