据1月2日路透社健康新闻报道,意大利研究人员称,某些水果和奶制品食物似乎能降低肝癌发病的风险。

意大利Aviano国立肿瘤研究所的Renato Talamini博士及其同事们的研究报告发表在《国际癌症杂志》上。他在接受路透社健康新闻记者采访时说,他们的研究“表明饮食与这种癌症发病风险有关。对于其他类型的癌症,特殊的水果和蔬菜似乎也能起保护作用。”

Talamini博士研究了185名肝癌患者和412名无瘤“对照”者。受试者回答饮食问卷,结果显示随着饮食的多样化程度提高,肝癌的发病风险降低。在考虑了其他可能影响发病风险的因素之后,该研究小组发现高牛奶和酸乳酪摄入量可降低78%的肝癌发病率。白肉的大量食用可降低56%的发病风险,而大量食用水果其风险可降低52%。蔬菜也具有明显的保护作用,但没达到统计学显著意义。

此外,研究者发现该结果对于乙型和丙型肝炎病毒(HCV)感染者仍然有效。

Talamini博士建议,为防止肝癌,人们应当“采用正确的饮食方案,富含水果和蔬菜。”另外,“限制酒精饮料以及通过健康性生活和避免针具共用以防止HCV感染”也同样重要。

Diet seen to affect liver cancer risk

NEW YORK (Reuters Health) - Certain foods, among them milk and fruit, appear to reduce the likelihood of developing liver cancer, according to Italian researchers.

Their study, Dr. Renato Talamini told Reuters Health, "indicated that diet has a relevant role in the risk of this cancer. As for other types of cancer, particularly fruits and vegetables seem to confer a protective effect."

Talamini, at the National Tumor Institute in Aviano, and colleagues studied 185 patients with liver cancer and a comparison group of 412 "controls" without cancer. The results are reported in the International Journal of Cancer.

The participants' responses to dietary questionnaires showed that as intake of various foods went up, the risk of liver cancer went down. After accounting for other factors that could affect the risk, the team found that high intakes of milk and yoghurt reduced the chances of developing liver cancer by 78 percent.

High consumption of white meat lowered the risk by 56 percent, and with high intake of fruit, it went down by 52 percent. Vegetables, too, apparently had a protective effect, but this didn't reach significance from a statistical standpoint.

The researchers saw that the findings held good for patients with hepatitis B and hepatitis C virus (HCV) infection.

Talamini advised that, to ward off liver cancer, one should "adopt a correct diet, rich in fruits and vegetables." Also important, he added, "is limiting consumption of alcohol beverages and avoiding HCV infection by practicing safe sex and eliminating needle sharing."
