Fruits and veggies are essential in a balanced diet for their nutritional content. These food groups are packed with vitamins and minerals, which help your body and immune system perform at their peak3.
Think of vitamins and minerals as your body’s maintenance crew – while they generally don’t fight infections directly, they help your adaptive immune system produce antibodies and white blood cells to destroy pathogens4.
There are plenty of vitamins, and you’ve probably heard of most of them; A, B6 and B12, C, D and more. Each vitamin serves a range of different purposes. Vitamin D supports healthy bone structure and protein production5, while vitamin C can be helpful in recovering from respiratory viruses like the common cold, influenza and COVID-196.
Our body also requires trace amounts of minerals for a healthy immune system. For example, a mineral like zinc is involved in healing wounds, synthesising new DNA and proteins and can even reduce cold symptoms.
Most importantly, our bodies are unable to create these vitamins and minerals on its own – which is where a healthy, balanced diet comes into play.
