COVID-19 falls under a family of viruses known as Coronaviruses (CoV) that ‘cause illness ranging from the common cold to more severe diseases’ according to the World Health Organization. Common signs of infection include, but are not limited to respiratory symptoms, fever, cough, shortness of breath and breathing difficulties.
Enter the immune system, but what does it have to do with a virus? The question is, what doesn’t it?! The immune system is one of defense in the body that protects a biological organism against disease. Its main functions are to eliminate any invading virus or foreign micro-organism (like a flu) and destroy any neoplasms (like cancer) in the body. This makes the system one that is very complex and in healthy persons its default mode is that of surveillance. All immune cells start off in the bone marrow, but mature in different parts of the body. Immune cells that stem from the bone marrow are important first responders for the body against infection. When a pathogen (bacteria that can cause disease) is discovered, immune cells migrate through the blood and lymph system to try to eliminate it.
Recent research has identified four specific cells that fight against COVID-19, similar to the way influenza is fought which leads to recovery in a healthy person. The advantage of this is that the recovery period can be tracked so that expected response time can further be examined. The most ideal situation with regards to COVID-19 would be not to contract it, but the second best option, and the one more in our control is to ensure our immune system is as strong as it can be. There are a host of foods that can help with this.
Ginger. Rich in phytochemical and antimicrobial potential, ancient cultures have used it to promote the immune system of the body. Having a cup of ginger tea is a great way to consume it.
Garlic. With anti-inflammatory effects it has influenced health for centuries. Season your meals with garlic for optimum benefit.
Citrus. Flavonoids in citrus fruits fight inflammation, reduce blood pressure, protect cells and promote production of immune cells. Fresh is best so start your morning off with a cup of freshly squeezed orange juice.
Yogurt. A study in the Journal for Clinical Nutrition shows that gut health is more important than previously credited. Plain yogurt is a great source of protein which improves the immune system, especially in the elderly whose immune response decreases with age. A great way to include it in your diet is to snack on it with fruit and spice toppings of your choice.
Almonds. Vitamin E can be obtained from this grain and is crucial for maintaining the immune system, especially among older persons. A handful of almonds or almond butter spread is an easy way to make it part of your diet.
Spinach Both Vitamin A and D are present in dark green leafy vegetables to help the body fight off bacteria when consumed. Get it in at breakfast time with your eggs or even in a green smoothie.
National Institutes of Health (NIH) says even mildly low levels of zinc can greatly impact the immune system since it is a trace element. Never have this on an empty stomach though! If you are taking a supplement it should be used at least an hour after your meal.
While the most important things during this time is to practice social distancing and good hygiene (always), having a stronger immune system helps you fare better if you do indeed end up ill. You are more likely to recover sooner as well.
Stay safe, eat well and wash your hands!
