Nutritional Profile

Green tea is renowned for its impressive nutritional content. The primary compounds responsible for its health benefits include polyphenols, catechins, and antioxidants. These substances are crucial in promoting health and preventing disease.

Key Compounds:

  • Polyphenols: These are natural compounds with antioxidant properties that help reduce inflammation and protect cells from damage.
  • Catechins: A type of polyphenol, catechins, especially epigallocatechin gallate (EGCG), are highly effective in combating oxidative stress and supporting overall health.
  • Antioxidants: Green tea is rich in antioxidants, which neutralize free radicals and protect the body from oxidative stress.

Essential Nutrients:

  • Vitamins: Green tea contains vitamins such as Vitamin C, which supports immune function and skin health, and various B vitamins that play a role in energy metabolism.
  • Minerals: It is also a source of important minerals like manganese and potassium, which are essential for bone health and fluid balance.
