Study from USP reveals: pure coffee is the most antioxidant

According to the researchers, pure coffee presented the highest antioxidant potential, while the addition of sugar slightly reduced this effect and milk caused a more pronounced drop. This occurs because the proteins in milk bind to the phenolic compounds, making it difficult to absorb them. Sugar, when heated, undergoes reactions that also generate antioxidant compounds, mitigating the loss. The study analyzed eight types of preparation, with and without caffeine, and concluded that caffeinated coffee presents the highest concentration of antioxidants. The filtration method also influences: the paper filter, the most common in Brazil, retains some of the compounds but helps reduce substances associated with cholesterol. For the researchers, the balance between science and consumption is essential. Pure caffeinated ...
