Coffee vs. Tea and Other Antioxidant-Rich Foods

Tea: Both green tea and black tea are celebrated for their antioxidant content, particularly polyphenols. Green tea is high in catechins, while black tea contains theaflavins and thearubigins. Coffee, on the other hand, is a powerhouse of phenolic acids, with a different profile of antioxidants compared to tea.

  • Green Tea: Rich in epigallocatechin gallate (EGCG)
  • Black Tea: Good source of complex flavonoids

Comparing to other foods, coffee shares the antioxidant stage with fruits and berries, as these are also high in polyphenols.

However, the unique blend of compounds like chlorogenic acids in coffee may offer different benefits. Cacao and cocoa found in dark chocolate are also high in flavonoids, but coffee often contains these compounds in higher concentrations.

When measuring antioxidant capacity, it’s important to consider the distinct phytochemicals each food or beverage contains, as they all contribute to health in varied ways.

List of Antioxidant Values in Foods (μmol TE/100g):

  • Coffee: 2,500 – 3,400
  • Green Tea: 1,253
  • Black Tea: 1,359
  • Dark Chocolate: 20,823
