Discover how diet and lifestyle can help support the immune system and how BBC Good Food's Healthy Diet Plans could help you get all the nutrients you need.
If you're keen to stay free from coughs and colds, it's difficult to know how best to protect yourself. Does it really help to stock up on super-strength vitamins? What about all the old wives' tales about bizarre food concoctions that are said to ward off symptoms?
The truth is that the natural function of a healthy immune system is the best defence against the common cold. While it's no guarantee that you won't succumb to sniffles or a sore throat, eating a balanced and varied diet that includes plenty of fruit and veg will ensure you're getting all the vital micronutrients that your immune system needs to work effectively.
Our Healthy Diet Plans are designed to help support your immune system by giving you five of your five-a-day (or even more), plus the nutrients that you need daily. If you haven't already, sign up today to receive free online access to the plan.
We asked nutritionist Kerry Torrens BSc. (Hons) PgCert MBANT for her three top tips to support the natural function of the immune system, plus how the recipes from our latest Healthy Diet Plan can help you achieve your goal.
3 tips for supporting your immune system
1. Top up your vitamin D
It's less of a concern when the sun's out, but during colder months, levels of vitamin D (the 'sunshine vitamin') are likely to be low. This vitamin is important for immune function, so try to include food sources regularly in your diet. Useful options include are eggs, mushrooms and oily fish like salmon – try the recipes in our latest 7-day Healthy Diet Plan, including a flavour-packed fish dish with potatoes. Read more about why we need vitamin D.
2. Eat onions and garlic
Onions, garlic and chives not only add flavour to dishes, they also contain potent oils that have anti-microbial properties. The health benefits of onions and garlic make them a great addition to a balanced diet. We've included these ingredients throughout our Healthy Diet Plan.
3. Choose nourishing foods
There is some evidence to suggest that a diet with too many calories and refined sugar can impair the immune system – yet another reason to limit your intake of sugar, alcohol and refined (white) carbs. All our Healthy Diet Plan recipes steer clear of refined, processed products and instead focus on nourishing ingredients, healthy fats, lean proteins and slow-release, complex carbohydrates.
