The importance of "eating your greens" might be a no-brainer, but have you considered the importance of eating your reds, yellows, purples, and whites too? Eating a rainbow of plant-based foods is critical to ensuring you're getting the vitamins and minerals you need for optimal health.
How does eating the rainbow support optimal health? Including a diverse range of plant-based wholefoods in your diet is critical to supporting a healthy gut, and our gut health plays a central role in influencing our overall health and wellbeing. For optimal health, we need to be eating a colourful range of fruits, vegetables, nuts, seeds, legumes, and wholegrains to support a varied nutrient intake.
Dr Megan Rossi, a renowned gut health researcher and registered dietician, recommends aiming for at least 20 to 30 varieties of plant-based foods each week. According to Dr Rossi, eating a variety of colours is critical because each colour group contains different nutrients that the gut thrives on - which is why we make sure you get served up every colour of the rainbow, in every Craft Smoothie box!
To help you achieve a healthier gut, our Superfood Smoothie Boxes include over 30 different varieties of fresh fruit, vegetables, and organic superfoods so you don't have to worry about meal planning and ticking off all the colours of the rainbow.
The colour of fruits and vegetables is influenced by specific phytonutrients, which are natural chemicals that help protect plants from external threats, and each colour indicates an abundance of specific nutrients. Let’s take a look at what the colour of your food can tell you about its nutrition, and how you can eat a more colorful range of phytonutrients to help your gut (and body) to function at its best.
