Tips for Avoiding Colds

As we slip into the season of colds and flu, what are some of the steps we can take to improve our chances of evading them? Firstly, ensure your immune system is provided with all the essential nutrients. Here are some useful foods.

How to avoid colds: choose the right foods.Beginning with breakfast, have an oat-based cereal eg museli, or make some oat porridge: oats contain a type of fibre known as beta-glucan which stimulates the white blood cells and macrophage cells of our immune system. Food to combat colds.This is also an opportunity to get some extra zinc by sprinkling a small palmful of pumpkin seeds over your cereal: in the laboratory, zinc has been shown to stop the cold virus multiplying, but studies also suggest it can shorten the duration of a cold (NHS Choices). Food to combat colds.Another ingredient you might like to include with breakfast, is a probiotic preparation, such as live or bio yoghurt, kefir, Yakult or Actimel. Probiotics appear to be useful in preventing upper respiratory tract infections (Cochrane Commentary). Food to combat colds.Finally, as regular intake of vitamin C appears to slightly shorten the duration and severity of a cold in some individuals (Cochrane Library), you could slice a kiwi or other citrus fruit over your cereal. Food to combat colds.A laboratory study suggests blueberries might also hold promise as an immune system aid (Oregon State University).

Food to combat colds.Having followed all that breakfast advice, we could turn to a mid-morning cup of tea. Black, green and white tea all contain catechins which seem according to a study in Japan, to reduce the likelihood of catching flu.

Food to combat colds.On to lunch or dinner, oily fish such as salmon, herring or mackerel offers you the benefits of omega-3 oils. Work done at Michigan State University suggests that the DHA in fish oil may enhance the activity of B-cells (specialised white blood cells) in your immune system. Food to combat colds.So consider a smoked salmon sandwich for lunch, or for a hot meal, have a salmon steak with which you could include sweet potato and carrots; these are rich in beta-carotene which the body converts to vitamin A and which performs a wide range of functions in the immune system. Food to combat colds.The salmon is also providing you with vitamin D, which like vitamin A, enables an array of immune system processes. Your breakfast milk and yoghurt will have contained vitamin D too.

Food to combat colds.If you are looking for a light evening meal, try a mushroom omelette: the eggs and mushrooms offer more vitamin D, whilst the protein contains the essential amino acid building blocks for our immune system cells. Food to combat colds.The mushrooms additionally offer further immune support. Food to combat colds.If it’s to your taste, add some garlic: a study published in 2014 suggested that people who took garlic supplements over a three month period, had fewer colds than those who took a placebo.

Food to combat colds.Secondly, following diet, try to get sufficient sleep, avoid overwork, and keep stress levels down.

Finally, attend to basic personal hygiene. Wash your hands at intervals eg at work where colleagues are touching the same door handles, office equipment etc, or after shopping when you have handled a supermarket trolley, petrol pumps etc.

These steps combined cannot completely eliminate the risk of a cold, but should give you a better chance of avoiding one as you are optimising defences on so many levels.
