It’s been known for some time that there’s a clear and robust link between nutrition status and immune function. ⁣

With regards to COVID-19, one of the biggest challenges is focused on reducing inflammation.⁣

To help reduce the severity of illness, a recent review paper published in the Journal of Clinical Medicine can certainly point us in the right direction.⁣

Here’s what we should consider to reduce the impact of this ‘pro-inflammatory storm’:⁣

1) Protein amount and quality is linked to immune function – focus on protein sources rich in essential amino acids as they may exert anti-inflammatory effects and reduce muscle wastage.⁣

2) Omega 3-fatty acids (EPA+DHA) may help supress inflammation, reduce platelet activation and viral replication.⁣

3) Reducing the intake of refined, high GI carbohydrates may be advisable as they can increase free radical production and inflammation.⁣

4) Fibre intakes of approx. 25-35g/day may reduce both systemic and gut inflammation – Therefore improving gut bacteria diversity is important for reducing inflammatory status.⁣

5) Probiotic supplements and fermented foods play a role in the adaptive and innate immune system. In this case, offering protection against viral infections via the ‘gut-lung axis’.⁣

6) Since respiratory infections have the ability to reduce micronutrient status, specific vitamins and minerals are needed in excess of normal daily requirements.⁣

7) Vitamins A, C, D, E, B6, B12, and folate, iron, magnesium and trace elements including zinc, selenium and copper play a pivotal role in disease susceptibility.⁣

8) During infection, it’s been suggested to follow a well-balanced diet (as always), with the addition of a multi vitamin + mineral supplement to ensure deficiencies or inadequate nutrition status doesn’t compromise resistance against infection.⁣

9) Carb-fat ratios is suggested to remain the same based on your activity levels and energy demands, however higher fat-carb ratios is suggested for very ill patients with respiratory deficiencies.⁣

Ultimately, a well-balanced diet that eliminates nutrient deficiencies will support your ability to tolerate covid-19 and other upper respiratory infections.⁣

That being said, a greater emphasis is needed for specific nutrients to reduce the severity of the disease.⁣

As with everything, focus on meeting the bodies demands.
