据国外媒体6月15日报道，瑞典于默奥大学研究所对当地约6.5万人进行调查后发现，每天喝煮咖啡平均超过4次的妇女比每天喝平均不到一次的妇女患乳腺癌风险要小，喝速溶咖啡的妇女在49岁前患乳腺癌风险要大于喝煮咖啡的妇女。
研究人员认为，煮咖啡有益健康，是因为所含脂肪酸是速溶咖啡的80倍。动物实验已证明，脂肪酸有抑制癌细胞生长效果。
另外，研究结果也显示，喝煮咖啡对男性健康不利，增大患胰腺癌和肺癌风险。
这一研究成果发表在最新一期《癌症成因和控制》（Cancer Causes &Control）杂志上。据统计，瑞典人均每年要喝8.2公斤咖啡。(生物谷Bioon.net)

Background
Despite potentially relevant chemical differences between filtered and boiled coffee, this study is the first to investigate consumption in relation to the risk of incident cancer.
Methods
Subjects were from the V?sterbotten Intervention Project (64,603 participants, including 3,034 cases), with up to 15 years of follow-up. Hazard ratios (HR) were calculated by multivariate Cox regression.
Results
No associations were found for all cancer sites combined, or for prostate or colorectal cancer. For breast cancer, boiled coffee ≥4 versus <1 occasions/day was associated with a reduced risk (HR = 0.52, CI = 0.30–0.88, p trend = 0.247). An increased risk of premenopausal and a reduced risk of postmenopausal breast cancer were found for both total (HRpremenopausal = 1.69, CI = 0.96–2.98, p trend = 0.015, HRpostmenopausal = 0.60, CI = 0.39–0.93, p trend = 0.006) and filtered coffee (HRpremenopausal = 1.76, CI = 1.04–3.00, p trend = 0.045, HRpostmenopausal = 0.52, CI = 0.30–0.88, p trend = 0.045). Boiled coffee was positively associated with the risk of respiratory tract cancer (HR = 1.81, CI = 1.06–3.08, p trend = 0.084), a finding limited to men. Main results for less common cancer types included total coffee in renal cell cancer (HR = 0.30, CI = 0.11–0.79, p trend = 0.009) and boiled coffee in pancreas cancer (HR = 2.51 CI = 1.15–5.50, p trend = 0.006).
Conclusion
These findings demonstrate, for the first time, the potential relevance of brewing method in investigations of coffee consumption and cancer risk, but they must be confirmed in future studies.
