What's The Best Food To Eat For Colds & Flu?

First thing first, chaps – there is no cure for the common cold. Nothing that doctors can give you, nothing that your mother can cook, no miracles that can be achieved by putting on a warm pair of socks and wrapping yourself in a blanket.
What you can do, though, is consume one of the foods that have shown some scientific successes in helping to prevent colds, boost your immune system, alleviate some of the horrible symptoms or shorten the overall suffering time.
Don't get your hopes up but hey, it can't hurt, can it?

Mais OUI mon petit filou! Make like the French and go heavy on the garlic. A 2001 study that tested 146 people found that people who took garlic supplements were much less likely to catch a cold and, if they did, they recovered a lot more quickly. However... the supplements contained 20 times the amount of allicin (the thing that makes garlic whiff) of a normal garlic clove, so unless you want to be really unpopular, perhaps the supplements are a better option.

Peppermint Tea

You already know that peppermint tea is good for calming your stomach and your bowels (which, tbh, can also be upset by colds and flu) but menthol, the active ingredient in peppermint, is also an 'expectorant'.

According to the University of Maryland, an expectorant thins mucus and therefore helps loosen phlegm and break up coughs.

Also – added bonus – it's good for calming irritated throats.

Perhaps there's a reason everyone in American films prescribes chicken soup when someone catches a cold? According to a study, consuming chicken soup is more effective than consuming hot water at increasing "nasal mucus velocity". This essentially means that soup helps you decongest better so you can actually blow your nose and hear out of your ears. The protein in the chicken can't do any damage, either.

When you go on a plane, you always end up with a cold, without fail. Well, perhaps elderberries are the answer. Last year, during a trial of 312 people travelling in economy class (bet the people in first class never get sick), some were given elderberry extract before travelling.

Later, it was found that the people who didn't take elderberry had "a significantly longer duration of cold episode days" after their flight.

Where do you get elderberry, you might ask? Well, there are small amounts of it in sambuca (the Latin name for elderberry is sambucus) but we'd recommend going with a supplement.

Honey is no good when it comes to curing colds but it has been shown to help with coughing, which is nice. A study on kids in Pakistan with the common cold found that honey could more effectively reduce the frequency, severity and extent to which a child coughed over five days than salbutamol, which is used to open up airways and treat asthma.
