- 营养流行病学 营养流行病学
- 遗传流行病学遗传流行病学
- 癌症研究 癌症研究
背景情况:
- 流行病学研究表明,饮食和结直肠癌 (CRC) 之间存在联系.
- 具体的饮食习惯和CRC之间的确切因果关系尚不清楚.
- 了解这些联系对于有效的CRC预防策略至关重要.
研究的目的:
- 调查9种饮食习惯与结直肠癌 (CRC) 风险之间的潜在因果关系.

Cancer Prevention
6.2K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
