What is the primary role of phytochemicals?

Phytochemicals are naturally occurring compounds found in plants that have been shown to provide numerous health benefits, primarily through their roles in disease prevention and health promotion. The primary role of phytochemicals is to act as disease-fighting compounds. They possess antioxidant, anti-inflammatory, and immune-boosting properties, which can help lower the risk of various chronic diseases such as heart disease, cancer, and diabetes.

Research indicates that many phytochemicals can neutralize free radicals, which are unstable molecules that can cause cellular damage and contribute to the development of diseases. Additionally, they may influence biological processes in the body, thereby enhancing overall health and well-being.

The other options focus on various nutrients like vitamins, minerals, and proteins but do not encompass the main function of phytochemicals. While they may play a role in supporting nutrient absorption or metabolism, their unique benefit lies in their potential to combat disease, making the first choice the most accurate representation of their primary role.
