Nutrition and Immunity during the Coronavirus Outbreak
With the current concerns around COVID-19 affecting us all, it’s reassuring to know that there are many easy lifestyle habits you can follow to keep your immune system strong and reduce the risk of infection.
There is a clear link between good nutrition and a healthy immune system. Here is how you can support your health through your daily diet.
The Best Immune-Boosting Foods
Foods that are rich in vitamin C, vitamin D, zinc, and an omega-3 fatty acid found in fish, DHA (docosahexaenoic acid) are critical for immune function.
- Citrus fruits: High in vitamin C, which is thought to help with the production of white blood cells, helping your body to fight off infections.
- Leafy greens: Leafy veggies like spinach are high in antioxidants, folate and vitamin A, as well as vitamin C. These nutrients all work to support the immune system.
- Berries (and most red or purple coloured fruits): These sweet and tasty fruits are loaded with antioxidants and disease-fighting nutrients known as anthocyanins.
- Broccoli: A great source of vitamins A and C.
- Garlic, ginger and turmeric: They don’t just add flavour to your meals, they also fight inflammation. Ginger is also great for relieving nausea and stomach upsets.
- Legumes: Lentils and chickpeas are good sources of zinc, which boosts immunity and helps to repair tissues.
Advice from the Experts
The World Health Organisation (WHO) recommends the following dietary habits:
- Eat fresh fruits and vegetables daily. Ideally, you should be eating 4 servings of fruit and 5 servings of vegetables a day.
- Include legumes, nuts and whole grains in your diet – for example, lentils, oats, or brown rice.
- If you include meat in your diet, eat red meat only 1-2 times a week, and poultry 2-3 times a week.
- Avoid foods and snacks that are high in added sugar, salt and fat.
- Drink 8-10 cups of water daily, to keep your body hydrated.
Food Safety Tips
Instead of ordering takeaways, prepare home-cooked meals and eat at home to reduce your rate of contact with others. Here are some food safety tips to keep in mind when you buy groceries:
- Avoid buying foods in leaking or damaged packaging.
- Refrigerate or freeze your food as soon as possible after grocery shopping.
- Store meat, poultry, seafood and eggs separately from produce like fruit and vegetables.
- Wash your hands thoroughly with soap and water before handling your ingredients.
- Rinse all produce thoroughly before use.
- Cook any meat, poultry and seafood at the safe minimum internal temperature. Keep it warm between cooking and serving.
- Clean all surfaces and utensils with hot, soapy water after use.
Supplements for Immunity
A healthy, balanced diet is first prize, but it might be necessary to give your body a boost and make up for anything your diet might be lacking by taking extra vitamins and minerals.
Low dose vitamins C and D are considered a safe, low-cost, and effective way of helping the immune system fight off COVID-19 and other acute respiratory tract diseases.
Supplements can be expensive, and in high doses they can be too much of a good thing with potentially harmful side effects, and interact with some medications, so you would be wise to speak to a health professional before taking supplements.
The following nutrients are known for their immune-boosting properties:
Minerals: Iron, zinc and selenium provide much-needed support to your immune system, and help you to effectively fight off illnesses. Your body can’t store zinc, so taking a supplement can help you to make sure you’re getting enough.
Vitamins: A, C, D and E
- Vitamin A helps your system to make antibodies, which fight off the germs that cause infection.
- Vitamin C promotes the growth of immune cells and antibody production.
- Vitamin D influences your response to infections.
- Vitamin E help to protect your cells against free radicals, and strengthen your body’s immune response.
Sun exposure is an easy, reliable way for most people to get vitamin D and will boost your mood and your health, giving you an overall sense of wellbeing. Exposure of the hands, face, arms, and legs to sunlight 2-3 times a week for about a quarter of the time it would take to develop a mild sunburn will cause the skin to produce enough vitamin D. (The necessary safe exposure time will vary, depending on your age, skin type, season, time of day, etc) Just 6 days of casual sunlight exposure without sunscreen can make up for 49 days of no sunlight exposure! Body fat acts like a kind of storage battery for vitamin D. During periods of sunlight, vitamin D is stored in fat and then released when sunlight is gone.
Take better care of yourself and your family by making healthy dietary choices, and remember to follow social distancing guidelines whenever you shop for groceries.
