喝出健康：咖啡是健康食品

结肠癌

    咖啡的其他混合物有降低结肠癌的作用。科学家长期以来质疑咖啡和预防癌症的关系。去年秋天，德国科学明确了他们之间的关系。在每一种咖啡中都有一种强抗氧化物－甲基嘧啶，它可促进血酶的转运以预防结肠癌。甲基嘧啶是在咖啡豆烘培过程中自然生成的一种化合物。研究还表明咖啡越纯，此化合物浓度越高，高度烘培是中度烘培的2－3倍。

Colon Cancer
Another coffee compound has been shown to reduce the risk of colon cancer. While scientists had long suspected a connection between coffee and cancer protection, last fall German researchers identified the link. A powerful antioxidant found almost exclusively in coffee, methylpyridinium, boosts blood enzymes widely believed to protect against colon cancer. Methylpyridinium is formed in the roasting process from a chemical found naturally in coffee beans. The stronger the coffee, the study also found, the higher the level of the compound, with darker roasts containing two to three times more than medium roasts.
