Cold hard facts
Flu season has arrived with a vengeance, but as scientific studies point to the benefits of zinc for sufferers, ABI JACKSON looks into whether four classic cold remedies really help our recoveries
ALWAYS curious about ways to help combat infections like colds and flu? Zinc is the latest mineral in the spotlight – a new study has found taking a daily zinc supplement ‘may cut how long respiratory infections last.’
It’s important to note that the research, which reviewed 28 existing studies, did not include data specific to Covid-19. But respiratory tract infections (RTIS) can include common cold, flu, sinus, throat and lung infection symptoms – like coughs, stuffed and runny noses, headaches, high temperatures and associated pain.
Published in the journal BMJ Open, it found people who regularly took zinc had less RTIS overall, and their symptoms cleared up more quickly when they did.
Of course, when it comes to infections like colds and flu, the best line of defence is to avoid spreading and catching them! Plus there are always other factors to consider – such as our individual general health and immune response, and lifestyle factors like how much sleep we’re getting.
But are there things that can give us a helping hand with fighting off a cold? Here we look at some classic cold remedies and how they may help...
CHICKEN SOUP
There is logic to this traditional favourite. Chicken soup is packed with phytoviral nutrients (found in garlic, onions and other veg and great for supporting immune function) and anti-inflammatory properties.
Studies have also suggested carnosine, a compound found in chicken, could help calm nasal congestion. And let’s face it, a steaming bowl of TLC is never going to hurt!
VITAMIN C
Popping some extra vitamin C when you’re run down with an infection is another classic, whether through supplements, fruit or juice. Studies have looked at whether this actually works, but overall, there’s no solid evidence it does.
That’s not to say vitamin C isn’t very important and helpful for healthy immune systems – that much is clear. It’s more about understanding how immune function works: we want to be supporting it in a general sense, rather than relying on a ‘quick boost’ when we get ill.
SPICES
Spices feature heavily in many traditional medicine and healthcare systems, including Ayurveda from India. When it comes to immune function and anti-inflammatory goodness, key examples are turmeric, cinnamon and ginger. In fact, ginger is known to be excellent for soothing the stomach and nausea too, which could be handy if a bout of flu leaves you feeling sickly.
Liquorice is said to have anti
effects, while thyme is hailed as being helpful for easing congestion, and the menthol in mint can help open up nasal passages.
As well as adding spices to cooking, brewing them up in a tea is a simple, soothing option, where you’ll get the benefits of breathing in the steamy aromas too, which can helped when you’re bunged up.
HONEY
This natural sweetener is famed for its antimicrobial and antibacterial properties and mixing up a cup of honey and lemon tea when you’re full of cold, or feel one coming on, is an age-old remedy.
Research has also found honey may help reduce cough symptoms.
