Coronavirus: Zinc, vitamin D and omega-3 may reduce risk

Nutrient deficiencies have been linked to decreased immune function, which means you become more susceptible to infections. Covid has been linked in some studies to decreased nutrient absorption, as the virus causes inflammation in the gut. The findings, published in the journal Public Health Nutrition, suggest that nutritional supplementation can improve your chance of surviving Covid-19 and reduce your risk of additional infections. The researchers advised to take nutritional supplements containing zinc, vitamin D and omega 3.

Vitamin D is a common vitamin deficiency in the UK, where it is difficult to find in food and our bodies do not produce enough of it in low sunlight.

Vitamin D has been linked to a strong immune system and may protect against some respiratory infections.

Researchers believe that vitamin D deficiency is becoming more common during the pandemic because people are spending less time outside.

Ethnic minorities, who are at greater risk of vitamin D deficiency, have also been significantly affected by the Covid virus.

A pre-pandemic survey showed that one in five people across the UK had low levels of vitamin D.

The prevalence of vitamin D deficiency increases seasonally as fewer people are outdoors during the winter.

Vitamin D deficiency in children can lead to developmental problems such as rickets.

Adults with vitamin D deficiency can develop osteoporosis and weak bones.

A study published in BMJ Nutrition, Prevention & Health examined the role of a variety of other vitamins on the immune system.

Vitamin A deficiency has been linked to impaired immune response and increased susceptibility to respiratory and gastrointestinal infections.

Zinc deficiency is associated with an increased risk of death from infection, and it can easily develop from some diets because the body is not able to store it in large amounts.

The researchers also examined the role of selenium in the immune system, but advised against the use of selenium supplements due to the damage that excess selenium can do to the body.

Extensive research has been done on how nutrition changes in elderly groups.

The skin becomes less able to produce vitamin D in sunlight, which requires greater dependence on diet and supplements.

Older adults are also more likely to have vitamin C and zinc deficiencies.

Many nutrient deficiencies do not produce direct symptoms but can have the effect of increasing the body’s exposure to harmful infections or developing chronic diseases.
