If this happens, you might need to take vitamin A supplements ( 25). Some people may develop vitamin A deficiency during infections such as COVID-19, and this may actually increase the severity of the disease. Researchers think it protects the ACE2 receptors, similarly to vitamin D, and may work on several other molecular targets to combat COVID-19 ( 24, 25). In the case of COVID-19, studies indicate that vitamin A reduces inflammation and oxidative stress, enhances the immune response, and may decrease the severity of the disease ( 24, 25). It has anti-inflammatory properties, and research has shown it may be beneficial for managing pneumonia and respiratory infections ( 1, 24, 25, 26). Vitamin A is a fat-soluble antioxidant carotenoid. One of these is vitamin A and its precursor, beta carotene ( 20, 22, 23). Of the 700 carotenoids identified in nature, only about 30 have been found in the human body. They’re found in nature in some colorful algae, bacteria, fungi, plants, fruits, and vegetables, some of which you can include in your diet ( 20, 21). Several foods are rich in vitamin D, including cod liver oil, salmon, herring, and some wild mushrooms.Ĭarotenoids are antioxidants as well as pigments (red, green, yellow, and orange). Vitamin D may help protect your lungs during novel coronavirus infection by disrupting viral attachment in your body. Their levels vary depending on the type of light they were exposed to as they were growing, according to older research ( 19). Wild mushrooms are a vegetarian source of vitamin D. Fortified orange juice: 25% of the DV per 100 grams.Salmon, wild-caught or farmed: 66% of the DV per 100 grams.Canned light tuna: 34% of the DV per 100 grams.Cod liver oil: 170% of the Daily Value (DV) per 1 tablespoon (13.6 grams).Here are seven foods rich in vitamin D, along with the amount of the vitamin each contains ( 12, 13, 14, 15, 16, 17, 18): Increasing your intake of vitamin D-rich foods while you have or are recovering from COVID-19 is a great way to reduce the risk of a vitamin D deficiency and potentially improve your immune response. That’s why it’s best to speak with a healthcare professional before you start taking vitamin D supplements regularly. However, some medications may interact with vitamin D supplements - including blood thinners, which are common among people with COVID-19 as a result of the increased risk of blood clotting. On average, people make approximately 80% of their vitamin D when their skin is exposed to sunlight (ultraviolet light) and get the remaining 20% from their diet ( 8).Īs a result, taking vitamin D daily may be a good idea if you’re in confinement due to COVID-19 and have little sunlight exposure ( 5). Vitamin D may also play a protective role and support healing of damaged tissues, primarily in the lungs ( 10). However, vitamin D interacts with the ACE2 receptors, potentially preventing the virus from binding to them, and reducing complications associated with COVID-19 ( 1, 10, 11). The novel coronavirus binds to ACE2 at the beginning of an infection, potentially leading to acute respiratory distress syndrome and severe illness in people with COVID-19 ( 10). In the body, vitamin D acts on angiotensin converting enzyme 2 (ACE2), a protein receptor found in the lungs and fat tissue ( 1, 7). This fat-soluble vitamin and hormone exerts an anti-inflammatory effect by suppressing overactivity of the immune system, according to newer and older research ( 1, 5, 8, 9). Vitamin D is the most frequently discussed micronutrient among nutrition experts for the management of COVID-19 ( 5). This article lists key nutrients, foods, and nutrition practices that may be beneficial for people who have COVID-19 or are recovering from it. These foods won’t prevent you from contracting the novel coronavirus or cure the disease, but they have been shown to support immune health. It’s important to note that this is an emerging area of research. The virus’s full name is severe acute respiratory syndrome coronavirus (SARS-CoV-2), and the illness it causes is called COVID-19 ( 4).ĬOVID-19 negatively affects nutritional status because it decreases appetite and may limit your access to nutritious foods during confinement, yet it simultaneously increases your body’s need for nutrients, such as vitamin D ( 3, 5, 6).ĭiet and nutrition can help support your immune health if you have COVID-19, especially if you consume foods with antioxidant and anti-inflammatory properties ( 1, 2, 5, 6, 7). The World Health Organization declared the novel coronavirus a pandemic in March 2020. Both inflammation and oxidative stress are elevated when you have COVID-19 ( 1, 2). Poor nutrition is associated with inflammation and oxidative stress, which compromise immune health.
