Phytochemicals are compounds produced by plants to give them their colour, smell or taste. They have a number of different functions, such as deterring predators or responding to tissue damage or infection.

Some phytochemicals are believed to have human health benefits as a result of their antioxidant, anti-inflammatory, or antiproliferative activity, and are also thought to have anticancer properties. Examples of phytochemicals include genistein from soybean, curcumin from turmeric root rhizomes, resveratrol from grapes, and lycopene from tomatoes.
