The real reason behind the ‘five a day’ fruit and vegetable recommendation

It is neither an empty slogan nor a passing trend: the recommendation to eat five portions of fruit and vegetables a day is based on solid scientific evidence and on their key role in preventing chronic diseases, regulating metabolism and maintaining a balanced diet

It is not a marketing claim either. It comes from the World Health Organization’s recommendation of at least 400 grams per day to help reduce the risk of cardiovascular disease, type 2 diabetes and certain cancers. On your plate, those 400 grams translate into roughly five portions of 80 grams.

So what makes them so special?

First, water: most fruit and vegetables contain more than 80–90% water, which helps with hydration, adds volume to meals and promotes satiety with very few calories.

Second, fibre: it slows the rise in blood sugar, improves bowel function, nourishes the gut microbiota and is associated with a lower cardiometabolic risk.

Third, vitamins and minerals: think of the vitamin C in citrus fruit and peppers for immune support and better absorption of plant-based iron; folate in leafy greens for cell renewal; and potassium in bananas, avocados or tomatoes for blood pressure regulation.

And fourth, bioactive compounds (polyphenols and carotenoids), which act as antioxidants and anti-inflammatory agents: lycopene in tomatoes, lutein in leafy greens, and anthocyanins in berries.
