Nutrition news from around the world:


Researchers from the US have indicated that if someone has a Vitamin D deficiency they are at a higher risk of contracting COVID-19.

A Chicago-based research team reviewed the Vitamin D status measured in the year prior in people who had contracted COVID-19 and found that those who a had a deficiency Vitamin D which was not rectified were almost twice as likely to fall ill with the virus.

Vitamin D, also known as the ‘sunshine vitamin’, is important for maintaining a healthy immune system,  bone and muscle development and health and may also play a role in preventing respiratory infections in people with a low Vitamin D status as demonstrated recently by researchers in Trinity College Dublin . In Ireland, there is a high rate of vitamin D deficiency as it can only be made by the action of sunlight on the skin for 10-15 minutes per day from late March until late September.

Researchers involved in this study have encouraged people to increase their intake of foods rich in Vitamin D (liver, oily fish, eggs, fortified foods like dairy products and cereals) and to consider taking a Vitamin D supplement containing a minimum of 400IU (10ug) of vitamin D per day. At-risk groups may benefit from a supplement containing 600-800IU (15-20ug) of Vitamin D per day.

Increasing Vitamin D status may help people, particularly those at high-risk, to improve overall health during the pandemic along with other recommended protective measures such as wearing a face covering, reducing social contacts and hand hygiene.

Other important factors for maintaining a healthy immune system include a varied and balanced diet, sufficient sleepregular exercise and reducing stress and anxiety.

Meal Plans:

We have added new plans to help fuel recovery for post-marathon. As we have discovered over the last few weeks of our ‘Marathon Series’, fuelling up correctly for longer duration runs is key for performance and recovery is just as important. These plans contain easily-digestible carbohydrate-based meals and adequate protein to ensure that you can replace the energy used by the body whilst running and to repair the body optimally. Meal plans are available to PRO members of the daveynutrition website.
