These are just a handful of the many studies that have looked at the health properties of foods. At first glance, they appear to lend weight to the existence of certain superfoods — certainly, the nutrients in these foods have been shown to have several health-promoting properties. It is a way that the food industry wants to persuade us that eating some foods can slow down the ageing process, lift depression, boost our physical ability, and even our intelligence. Labelling some foods as ‘super’ in the media may also give the impression that other foods in our diets are not as healthy when, in reality, these foods often provide nutrients just as valuable as those found in superfoods.
When it comes to ensuring a balanced nutrient intake for good health, we need to increase the range of nutritious foods in our diets rather than focusing solely on a handful of foods claimed to be ‘super’. Importantly, this should include a greater quantity and variety of fruits and vegetables. Many European countries provide food-based dietary guidelines to help people reach this goal.
