Eat The Rainbow

Fruits and vegetables contain phytochemicals that protect the plants from fungi and viruses as part of their immune system, and can strengthen the human immunosystem as well in addition to having other benefits such as bonding with free radicals or stimulating production of vital hormones. Different plants naturally have different attributes and as such affect the body differently, hence the need for variety in our diets to ensure the plethora of vitamins, minerals, and other nutrients required for proper health.

This is where the idea of “eating a rainbow” comes from. Little kids complain about eating “green food” because these are the easiest vegetables to acquire in general and also tend to be the blandest.
