The foods you should be eating to protect your body against coronavirus

As the coronavirus outbreak sweeps across the globe, people are stockpiling disinfectant, preparing to self-isolate and cancelling their travel plans to affected countries.

And while there is no one way to avoid infection entirely, strengthening your immune system with particular food ingredients can go a long way to reduce your risk of contamination.

Australian nutritionists and health professionals have shared how antioxidant-rich live bacteria supplements, garlic, eggs and turmeric can help boost your health fast.

ONION

Antioxidant-rich foods including berries, garlic and onion are essential for building up the immune system, which fights off viruses, nutritionist Lee Holmes wrote in a blog post.

They contain Vitamins C, B and E which help reduce the risk of disease and help fight off infections. 

According to Lee, antioxidant-rich foods, which also include eggplants, pumpkins and carrots, should be eaten at least once a day.

TURMERIC

‘Now that we’ve fought off oxidative damage, it’s time to look at controlling inflammation,’ Lee said.

‘Consuming anti-inflammatory rich foods is essential when it comes to the immune system. To ensure you’re eating enough anti-inflammatory rich foods, up your intake of vegetables and fruits.’

Eating at least five vegetables each day can help fight inflammation and ingredients such as turmeric have additional benefits.

‘One of my favourite anti-inflammatory ingredients is turmeric. I add it to everything. Seriously. The compound in turmeric known as curcumin holds a plethora of benefits,’ Lee said. 

OYSTERS 

Zinc can be found in a range of foodstuffs including grass-fed beef, lamb, spinach and oysters – and Lee describes it as ‘the absolute underdog of the immune system pyramid’.

It helps skin and bones and is particularly useful for fighting the flu as it attacks the infected cells.  

‘Eating foods rich in zinc is vital when it comes to looking after your immune system, as well as your gut,’ she explained.

You can include zinc in your diet by incorporating more fish and seafood into your day. 

LIVE BACTERIA SUPPLEMENTS

Nutritional therapist Hannah Braye said most people are aware of how bacteria supplements can benefit your digestion, but many others don’t realise how good they can be at supporting the immune system. 

‘Over 70 per cent of the immune system resides in the lining of the gut and is supported by a diverse community of bacteria,’ Ms Braye told FEMAIL.

‘Beneficial species of gut bacteria have been shown to influence both the innate and acquired immune systems. Taken over the winter months, they have been shown to significantly shorten common colds and reduce the severity of symptoms.’

Ms Braye recommends multi-strain products like Bio-Kult Multi-Strain Advanced Formula, which contains 14 different strains, as they are believed to have more positive benefits overall.

EGGS

Eggs are a very nutritious food containing more than 20 essential vitamins and minerals

Eggs are an extremely nutritious food containing more than 20 essential vitamins and minerals including good quality protein, good fats and vitamins A and E, nutritionist Susie Burrell wrote on her website.

You can get many of these vitamins and minerals from other foods, but the one exception is selenium, a ‘powerful antioxidant that plays a key role in cell health and is found in very few foods including eggs and Brazil nuts’.

A single egg, for example, provides a quarter of your daily selenium requirement.

As well as infertility, muscle weakness, hair loss and mental fog, depleted selenium can lead to a weakened immune system.  

What cooking ingredients will help to boost immunity? 

Mushrooms

They are a powerhouse for supporting the immune system and have been acknowledged by eastern medics for thousands of years for their superpowers. The therapeutic component in these wonderful fungi act as antibacterial, anti-inflammatory and cell-regenerating agents.

Ginger

These ingredients provide antibacterial, antioxidant and anti-inflammatory action to relieve the unfavourable symptoms of flu.

Garlic, chilli and onion

Supporting your body’s natural defence system. Allicin, a compound in garlic, is known to boost the white blood cell’s response to illness. Onions also have multiple immunity-supporting compounds, whilst green chillies are rich in vitamin C to boost resistance to infection.

RHODIOLA ROSEA

A herb that blooms in the cool, high-altitude regions of the continent, Rhodiola Rosea is widely acknowledged for its ability to assist in managing stress and anxiety in humans. 

A study by Appalachian State University Human Performance Laboratory at the North Carolina Research Campus also suggests this super herb can help decrease the infection rate of viruses.

In this study, marathon runners who took 600 milligrams of Rhodiola Rosea one month before their race had a higher chance of protection against viral infection after the marathon. 

This is significant because runners (and other athletes) often become extremely prone to viral sickness after exerting their bodies for an extended period.

Rhodiola Rosea can be consumed in tea or tablet form as found in Clariti supplements by Australian company, Xootro.

GREEN TEA  

Green tea contains flavonoids that are believed to help block the production of virus-spreading enzymes in the body. 

Beyond this, it is extremely high in antioxidants and can give our bodies a much-needed boost to help fight viral symptoms when we become infected by a virus.

It is also listed as a metabolism booster which is vital to maintaining a healthy, well-flushed body.  

Lee Holmes’s immune-boosting roasted garlic bisque recipe

Ingredients 

Serves four 

  • 4 garlic bulbs, unpeeled 
  • 60 ml (2 fl oz/14 cup) extra virgin olive or coconut 
  •  1 brown onion, roughly chopped 
  • 1 leek, white part only, washed well and roughly chopped 
  • 1 litre (35 fl oz/4 cups) good-quality chicken stock or bone broth
  •  3 parsnips, peeled and roughly chopped 
  • 3 free-range egg yolks 
  • 2 pinches of ground nutmeg, or to taste 100 g (312 oz) macadamia nuts, dry-roasted and roughly chopped or crushed
  •  2 tablespoons chopped flat-leaf (Italian) parsley, to serve 

Method

  1. Preheat the oven to 200°C (400°F) 
  2. Cut about 5 mm (1/4 inch) off the tops of the garlic bulbs to expose the cloves
  3.  Place the garlic bulbs in a small baking dish, add 1 tablespoon of the oil and toss to coat
  4.  Turn the garlic cut side up, then cover the dish tightly with foil
  5.   Bake for 30–35 minutes, or until the garlic skins are golden brown and tender
  6.  Leave to cool, then squeeze the garlic out of the skins
  7.  Heat the remaining olive oil in a large saucepan over medium heat. Sauté the onion and leek for 3–4 minutes, or until softened
  8.  Add the roasted garlic, stock and parsnip. Reduce the heat to low, then cover and simmer for about 30–35 minutes, or until the vegetables are tender
  9.  Leave to cool slightly, then purée the soup using a food processor or hand-held stick blender
  10. In a small bowl, whisk the egg yolks. While the soup is still warm, and with the food processor or blender still running, add the egg yolks and whiz until combined
  11.  Season to taste with the nutmeg, and sea salt and freshly ground black pepper
  12.  If you need to warm the soup to serve, stir gently over low heat until heated through, but no longer than 1–2 minutes, or the yolks will curdle
  13.  Ladle into bowls, top with the macadamias and parsley and serve
