“Public health officials are encouraged to include nutritional strategies in their recommendations to improve public health.”
Optimal Nutritional Status for a Well-Functioning Immune System Is an Important Factor to Protect against Viral Infections
You can read the abstract and full text here, but here’s the gist of it for you:
The role nutrition plays in supporting the immune system is well-established. A wealth of mechanistic and clinical data show that vitamins, including vitamins A, B6, B12, C, D, E, and folate; trace elements, including zinc, iron, selenium, magnesium, and copper; and the omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid play important and complementary roles in supporting the immune system.
Inadequate intake and status of these nutrients are widespread, leading to a decrease in resistance to infections and as a consequence an increase in disease burden. [Ed: my emphasis]
Against this background the following conclusions are made:
(1) supplementation with the above micronutrients and omega-3 fatty acids is a safe, effective, and low-cost strategy to help support optimal immune function;
(2) supplementation above the Recommended Dietary Allowance (RDA), but within recommended upper safety limits, for specific nutrients such as vitamins C and D is warranted; [Ed: and a few others I’d say], and
(3) public health officials are encouraged to include nutritional strategies in their recommendations to improve public health.
Couldn’t have put it better myself, although I’d probably have put it much stronger! Check the Purehealth COVID Guidance document, where I have put recommended supplements, dosages and foods for you, but if in doubt, choose a really good wellbeing protocol such as:
Nutripowder (a great mix in an absorbable, easy form you can add to your morning juice or smoothie – you can also add the following to it if you want to make life really easy! )
Essential Fatty Acids (a good mix of the different types because actually Omega 6 is also required for good immunity, not just omega 3)
Probiotics (because it all starts with the gut, as usual!)
That should bring your nutrient status up well, which can only help your immunity strength. Hope that helps.
