Whole foods are foods to which nothing has been added or taken away, that haven't been unnecessarily processed or loased with additives, colourings or flavourings.
It is important to choose unrefined foods whenever you can because in doing so you get the greatest intake of vitamins, minerals, and fibre. When food is processed some of the nutrients are lost.
A whole foods diet should include a variety of foods such as fruit, vegetables, dairy products or alternatives (soy milk, almond milk), healthy fats and oils, natural sweeteners, grains, pulses, beans and seeds.
Basically, eating fresh is the way to go!
It is actually quite easy to eat well and cook simple meals that are satisfying and use fresh produce.
