鱼类和素食可以降低癌症发病率(除宫颈癌和脑瘤需要更多研究外)。鱼类比素食更优。请关注highlighted部分。在消化道方面鱼类更优，在泌尿生殖道和造血系统方面素食更佳(RR为危险指数，>1,比肉食危险， Numbers of incident malignant cancers (N) and relative risks (RRs) and their 95% confidence intervals (95% CIs) by diet group among 33 697 meat eaters, 8901 fish eaters and 21 810 vegetariansa Cancer site Meat eater Fish eater Vegetarian P for heterogeneity (ICD-10 codes) N RR N RR (95% CI) N RR (95% CI) Upper GI tract (C00-10, 13, 15) 56 1 4 0.44 (0.16–1.25) 18 0.81 (0.45–1.46) 0.218 Stomach (C16) 38 1 2 0.29 (0.07–1.20) 9 0.36 (0.16–0.78) 0.007 Colorectum (C18–20) 243 1 31 0.77 (0.53–1.13) 110 1.12 (0.87–1.44) 0.177 Colon (C18) 156 1 17 0.68 (0.41–1.14) 66 1.12 (0.81–1.54) 0.173 Rectum (C19–20) 87 1 14 0.92 (0.51–1.64) 44 1.12 (0.75–1.67) 0.776 Pancreas (C25) 46 1 6 0.82 (0.34–1.96) 19 0.94 (0.52–1.71) 0.898 Lung (C34) 114 1 8 0.59 (0.29–1.23) 43 1.11 (0.75–1.65) 0.225 Melanoma (C43) 115 1 21 0.90 (0.55–1.47) 49 0.89 (0.61–1.29) 0.799 Female breast (C50) 654 1 133 1.05 (0.86–1.28) 237 0.91 (0.77–1.08) 0.383 Cervix (C53) 17 1 10 2.05 (0.91–4.63) 23 2.08 (1.05–4.12) 0.069 Endometrium (C54) 71 1 8 0.61 (0.29–1.30) 22 0.75 (0.45–1.28) 0.304 Ovary (C56) 98 1 8 0.37 (0.18–0.77) 34 0.69 (0.45–1.07) 0.007 Prostate (C61) 207 1 14 0.57 (0.33–0.99) 70 0.87 (0.64–1.18) 0.092 Kidney (C64) 37 1 2 0.36 (0.09–1.52) 11 0.76 (0.36–1.58) 0.252 Bladder (C67) 65 1 7 0.81 (0.36–1.81) 13 0.47 (0.25–0.89) 0.05 Brain (C71) 44 1 11 1.39 (0.69–2.80) 26 1.25 (0.72–2.16) 0.581 Lymphatic/haematopoietic tissue (C81–96) 180 1 28 0.85 (0.56–1.29) 49 0.55 (0.39–0.78) 0.002 Non-Hodgkin's lymphoma (C82–85) 81 1 13 0.86 (0.47–1.58) 23 0.57 (0.35–0.95) 0.079 Multiple myeloma (C90) 34 1 4 0.72 (0.25–2.10) 4 0.25 (0.08–0.73) 0.015 Leukaemia (C91–95) 51 1 10 1.18 (0.58–2.40) 17 0.78 (0.43–1.43) 0.565 All sites (C00–97) 2204 1 317 0.82 (0.73–0.93) 829 0.88 (0.81–0.96) 0.001 ICD=International Classification of Diseases; GI=gastrointestinal. a Estimated by Cox proportional hazards regression with age as the underlying time variable, adjusted for smoking (never smoker, former smoker, light smoker (=15 cigarettes per day)), alcohol consumption (-2, unknown), physical activity level (low, high, unknown) and, for the women-only cancers, parity (none, 1–2, 3+, unknown) and oral contraceptive use (ever, never, unknown), and stratified by sex (where appropriate) and study/method of recruitment, using separate models for each end point. http://www.nature.com/bjc/journal/v101/n1/fig_tab/6605098t2.html#figure-title
