Final Answer:
Phytochemicals, such as flavonoids, carotenoids, and polyphenols, are compounds that naturally exist in plants and are associated with decreasing the risks of cancer and heart diseases.
Step-by-step explanation:
Phytochemicals are bioactive compounds found in plants that have been extensively studied for their potential health benefits. Flavonoids, present in fruits, vegetables, and beverages like tea, are known for their antioxidant properties, helping to combat oxidative stress and inflammation, thereby contributing to a lower risk of chronic diseases. Carotenoids, found in carrots, sweet potatoes, and leafy greens, are associated with heart health and may reduce the risk of certain cancers. Polyphenols, abundant in fruits, vegetables, and whole grains, exhibit antioxidant and anti-inflammatory effects, potentially reducing the risk of cancer and cardiovascular diseases. Including a variety of plant-based foods in the diet ensures a rich intake of these beneficial phytochemicals.
