Adequate nutritional status protects people over 65 against Covid-19

The coronavirus SARS-CoV-2 is currently not as feared as it was in 2020, but despite this, people are still getting Covid-19. People over 65 are especially vulnerable. A small Chinese observational study shows that well-nourished people over 65 have less to fear from the virus.


Adequate nutritional status protects people over 65 against Covid-19


Study
Researchers from Ruijin Hospital in Shanghai studied 324 people over the age of 65 who had contracted Covid-19 in the period April-June 2022. During that period, viruses of the first generation of omicron variants of SARS-CoV-2 were dominant. The researchers divided their study participants into a group with mild symptoms and a group with moderate to severe Covid symptoms.

The researchers had access to the medical data of the study participants. This allowed them to look for protective factors.

Results
Good nutritional status protected study participants from serious illness. The Chinese determined nutritional status using the Mini Nutritional Assessment [MNA].

You can see this questionnaire below. We took it from [J Nutr Health Aging. 2013 Apr;17(4):339-44.]. Click on it for a larger version.


Adequate nutritional status protects people over 65 against Covid-19


On the MNA you can score a minimum of 0 and a maximum of 11 points.

Every point that people over 65 score on this list reduced their risk of moderate-to-severe Covid by 14 percent.

How much green tea you need to drink to protect yourself against the flu?
As early as 2011, Japanese researchers reported that drinking 3 cups of green tea daily may drastically reduce the risk of flu.

Kiwis help you to get rid of common colds faster (and lessen the symptoms)
If people over 65 eat 4 kiwis a day, they can still get a cold - but their cold will be over faster. In addition, they will suffer less from some symptoms.

Rice bran stimulates the production of IgA antibodies
If covid returns this winter, which natural immune boosters can you use? Vitamin D, zinc and quercetin, of course. Perhaps also magnesium and Q10, vitamin K, selenium and fish oil. And what else?
