What is a phytochemical? A phytochemical is a plant constituent that’s believed to have protective and preventive health benefits. Phytochemicals are naturally produced by a plant to protect itself. When you consume the plant, those naturally present chemicals may benefit you as well.
There are thousands of different types of phytochemicals, a couple familiar examples are lycopenes, isoflavones and flavanoids. And each plant contains a variety of these compounds.
Because phytochemicals are inherent in all fruits, vegetables, legumes and grains, eating a plant based diet guarantees you’ll reap their probable benefits. Although some phytochemicals are concentrated into supplements, evidence suggests diminished effects because synergy is a beneficial component. So, no short cut to eating plenty of plants daily.
The health benefits of phytochemicals are largely supported by numerous epidemiological comparison studies. These indicate plant based diet populations have lower rates of some diseases, particularly cancer, diabetes, heart disease and cataracts. Research into the role a specific phytochemical may play in this beneficial difference is ongoing.
Some phytochemical actions that might contribute to disease prevention include:
- antioxidant activity
- stimulate enzymes
- imitate hormone action
- anti-bacterial properties
- prevent pathogen adhesion
- protects DNA from carcinogens
Research into how the huge number of phytochemicals work is still in its infancy. Until such time more is known, the most prudent action you can take is consume a nutrient filled diet consisting predominantly of phytochemical rich fruits and vegetables. Why? Because these functional foods likely provide health benefits far beyond just sustaining health.
