As winter approaches, COVID-19 and other respiratory infections are likely to become more common. It is almost three years since the start of the pandemic, but the virus still has not gone away. Now research findings are pointing to the crucial role diet plays in your chance of catching and becoming seriously ill with this disease.
Studies have shown people who eat the ‘highest quality diet’ are about 10% less likely to develop COVID 19 than those with a poor diet. Those with a good quality diet are also 40% less likely to get severe COVID-19 requiring treatment in hospital regardless of age, ethnicity, socioeconomic status, gender.
The sort of diet that can help protect you from catching COVID-19 is rich in plant foods such as fruits, vegetables, wholegrains, nuts and seeds. Oily fish and, fermented foods such as live yogurt, kimchi and unpasteurised cheese have also been shown to improve the quality of the diet.
Research has also shown a plant-based diet containing oily fish and fermented foods can help your recovery if you have caught COVID-19.
Scientists have found is that it is not single food that help to build up your immune system and help to protect you from catching COVID-19 but ‘diet quality’ that is an important factor.
Diet quality is a term used by nutritionists to describe the overall pattern of an individual’s food intake over weeks and months.
What we eat has a major effect on our overall health. Eating a good quality diet can help people to keep a healthy weight. Being overweight is a major risk factor for catching and becoming ill with COVID-19.
The food we eat also has a major impact on our gut microbiome (bugs in our gut) and our immune system. Having a healthy gut microbiome is key to having a healthy immune system.
If you have COVID-19, it’s important that you top up your fluid levels and stay hydrated as the body uses a lot of water if it is fighting an infection. Eat plenty of nutritious high energy food from the lists above. Eating smaller meals or snacks throughout the day may be easier than eating big meals.
