What are phytochemicals found in foods known for?

Phytochemicals are natural compounds found in plants that contribute to the vibrant colors, flavors, and disease resistance of fruits and vegetables. They are known for promoting overall health and preventing diseases due to their antioxidant, anti-inflammatory, and immune-boosting properties. Many studies suggest that a diet rich in phytochemical-containing foods can lower the risk of chronic diseases such as heart disease, diabetes, and certain cancers. This health-promoting aspect underscores the significance of including a variety of plant-based foods in the diet to benefit from these bioactive compounds.

The other options do not capture the proven benefits of phytochemicals. While essential vitamins are crucial to health, they are not the only benefit offered by plant foods; thus, focusing solely on vitamins misses the broader role of phytochemicals. Furthermore, phytochemicals do not contribute to obesity; rather, they are often found in nutrient-dense foods that can help maintain a healthy weight. Lastly, phytochemicals do not reduce fiber content in foods; many high-phytochemical foods, like fruits and vegetables, are also excellent sources of dietary fiber, which is important for digestive health.
