How do catechins work in the body?
Catechins are a type of flavonoids, a group of phytochemicals or plant-based compounds that occur naturally in green tea, red wine, fruits, and vegetables. The flavonoid catechins have potent antioxidant properties that offer several health benefits. The mechanism behind the health-promoting effects of catechins is through the regulation of signal transduction pathways that control various cellular processes such as inflammation, cell proliferation, and apoptosis (programmed cell death). Catechins interact with several molecular targets in the body, including enzymes, receptors, and signaling molecules, to induce several biochemical reactions that promote health and wellness.
- Antioxidant effects: Catechins are potent antioxidants that scavenge free radicals and reactive oxygen species (ROS) that cause cellular damage and oxidative stress. Free radicals are unstable molecules that damage cells and contribute to aging, cancer, and chronic diseases. Catechins neutralize free radicals by donating an electron to stabilize them and prevent cellular damage.
- Inflammation reduction: Catechins can reduce inflammation, which is a vital physiological response to infection, injury, or stress. However, chronic inflammation can lead to several diseases such as arthritis, heart disease, diabetes, and cancer. Catechins regulate multiple molecular targets that mediate inflammation, such as cytokines, chemokines, and prostaglandins.
- Boost immune function: Catechins can enhance immune function and prevent infections by regulating the activities of immune cells such as T-cells, B-cells, and natural killer cells. Catechins can also inhibit the growth and survival of bacteria, viruses, and fungi.
Overall, catechins are potent bioactive compounds that offer several health benefits through their antioxidant, anti-inflammatory, and immune-boosting effects. Catechins can protect the body from cellular damage and prevent chronic diseases by regulating several molecular targets in the body.
Conclusion
Catechins have potent antioxidant properties that scavenge free radicals and reduce oxidative stress, inflammation, and enhance immune function. The bioactive compounds in catechins regulate several molecular targets in the body, such as cytokines, chemokines, and prostaglandins, to promote health and wellness.
