What are Phytonutrients?

Phytonutrients are naturally occurring compounds found mainly in vegetables and fruits.

They have significant health benefits and just a small increase in your daily intake can have a dramatic impact on your overall health.  They have antioxidant, anti-inflammatory and anti-carcinogenic effects and a recent study in the Journal of Nutrition, has shown that a high intake has been associated with reduced mortality in older adults.

There have been numerous research studies into the benefits of including phytonutrients in the diet:

  • In 2006 an analysis of a number of studies found a 26% reduced risk of stroke in people consuming more than 5 servings of fruit and vegetables.
  • In 2010 green leafy vegetables were found to reduce the risk of diabetes and furthermore, an increase of 1.15 servings of fruit and vegetables a day was associated with a 14% decrease in the incidence of Type 2 diabetes.
  • Flavonoids which are found in fruit and vegetables were associated with a significantly reduced risk of many different types of cancer.
  • A similar study found a 41% reduced risk of dementia with a high dietary intake of flavonoids.

So where do you find these phytonutrients?

  • Chlorophyll and lutein are found in green vegetables such as kale, broccoli, cabbage, spinach
  • Lycopene and capsanthin can be found in red fruit and vegetables including tomatoes, red peppers, pomegranate and watermelon
  • beta carotene, which are body converts into Vitamin A, is found in yellow and orange vegetables such as pumpkin, squash, carrots and sweet potatoes
  • Allicin and favanols are found in white vegetables such as the onion family: onion, garlic, chives and leeks
