Different-coloured plants are linked to higher levels of specific nutrients and health benefits. While eating more vegetables and fruit is always a good idea, focusing on eating a variety of colours will increase your intake of different nutrients to benefit various areas of your health.
The general consensus of recommended daily intake (RDI) is 2 serves of fruit and 5 serves of vegetables. There are various health organisations that recommend up to 5 fruit and 10 veg serves per day.
The best way to get all of the vitamins, minerals and nutrients you need is to eat the average RDI and include a variety of colourful fruits and veggies.
