Eat well

A pro-immunity eating plan goes beyond citrus, blueberries and ginger shots. Rather than focusing on so-called superfoods, the better play is to shoot for a broad and colourful amount of produce, says Dr Macciochi. “If your diet is diverse, you’ll be getting a lot of phytonutrients [compounds found in plants], which help protect cells, tissues and organs over a lifetime.” Plus, fibre. “The gut microbiome is key for regulating the immune system, so it’s thinking about getting a diversity of fibre – not just fruit and veg, but legumes, beans and pulses, nuts, seeds and whole grains.” Aim for the recommended 30g a day from a variety of sources.
