Phytonutrients are plant-based chemicals available through a diet that includes whole grains, beans, fruits, vegetables, spices, and herbs. Research suggests that these bioactive compounds, which contribute to a plant's colour, taste, and smell, also have beneficial health effects. For example, flavonoids are compounds found in cocoa, apples, and green tea. Epidemiological studies have suggested a positive association between diets high in flavonoid-rich foods and cardiovascular health, while clinical trials have shown lower blood pressure results after consumption of flavonoid-rich food. In addition, phytochemicals such as sulforaphane and lycopene have health-promoting properties and protective effects against many diseases, including cancers1 Even with the suggested benefits, according to a Centres for Disease Control and Prevention report, only one in ten adults meet the recommendations for fruit and vegetable daily intake, potentially increasing their risk for developing chronic diseases such as Type 2 Diabetes and heart disease.
