Plant foods contain thousands of natural chemicals that are produced as part of their normal metabolic activities. These chemicals are called “phytonutrients” and help to increase a plant’s vitality and protect it from germs, fungi, bugs, and other threats.
Not only do phytonutrients benefit plants, it also have the ability to provide benefits to those who enjoy eating plant food. There are thousands of phytonutrients in our food supply and eating the minimum requirement of five fruit or vegetables per day can have a huge impact on our health because it's health-promoting properties like antioxidant, anti-inflammatory, and liver-health-promoting activities.
Scientists have confirmed that the intake of certain foods like fruit, vegetables and legumes, is highly protective against many different diseases, including chronic degenerative diseases. Until the arrival of the pharmaceutical industry in the 19th century, most medicinal remedies came from plants.
Fruits and vegetables are concentrated sources of phytonutrients; other plant foods like whole grains, legumes/beans, nuts and seeds, and herbs and spices also contain phytonutrients.
Since many phytonutrients serve as the pigment that gives foods their hue, you can identify many phytonutrient-rich foods by looking at their colour.
