Fruit and Vegetable Intake in Relation to Prostate Cancer in Iranian Men: A Case-Control Study
Askari, Faezeh,Parizi, Mehdi Kardoust,Jessri, Mahsa,Rashidkhani, Bahram Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.13
Background: Findings of epidemiologic studies on the relationship between fruit and vegetable consumption and prostate cancer (PCa) risk have been inconclusive. We therefore examined the association between intake of fruits and vegetables and PCa risk in Iran. Materials and Methods: In this hospital based, case-control study, a total of 50 patients with PCa and 100 controls underwent face-to-face interviews. Regression analysis was used to examine the relation between fruit and vegetable intake and PCa risk. Results: A protective independent effect was observed for the highest tertile of total fruit and vegetable (OR: 0.33, CI: 0.04-0.30, p value<0.001), total fruit (OR: 0.30, CI: 0.06-0.4, p value=0.03) and total vegetable (OR: 0.31, CI: 0.02-0.21, p value<0.001) consumption. Within the group of fruits, a significant inverse association was observed for apple and pomegranate (p trends were 0.01 and 0.016, respectively). In the vegetable group, a significant inverse association was observed for tomatoes (p trend<0.001) and cabbage (p trend=0.021). Conclusions: The results of the present study suggested that fruits and vegetable intake might be negatively associated with PCa risk.

Dietary Patterns in Relation to Prostate Cancer in Iranian Men: A Case-Control Study
Askari, Faezeh,Parizi, Mehdi Kardoust,Jessri, Mahsa,Rashidkhani, Bahram Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.5
Background: Prostate cancer is the most frequently occurring cancer among males in economically developed countries. Among the several risk factors that have been suggested, only age, ethnicity, diabetes, and family history of prostate cancer are well-established and primary prevention of this disease is limited. Prior studies had shown that dietary intake could be modified to reduce cancer risk. We conducted a hospital-based, casecontrol study to examine the association between dietary patterns and prostate cancer risk in Iran. Materials and Methods: A total of fifty patients with prostate cancer and a hundred controls underwent face-to-face interviews. Factor analysis was used to determine the dietary patterns. Multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Results: We defined two major dietary patterns in this population: 'western diet'(high in sweets and desserts, organ meat, snacks, tea and coffee, French fries, salt, carbonated drinks, red or processed meat) and 'healthy diet' (high in legumes, fish, dairy products, fruits and fruit juice, vegetables, boiled potatoes, whole cereal and egg). Both Healthy and western pattern scores were divided into two categories (based on medians). Higher scores on Healthy pattern was marginally significantly related to decreased risk of prostate cancer (above median vs below median, OR =0.4, 95%CI=0.2-1.0). An increased risk of prostate cancer was observed with the higher scores on the Western pattern (above median vs below median, OR=4.0, 95%CI=1.5-11.0). Conclusions: The results of this study suggested that diet might be associated with prostate cancer among Iranian males.

In this study we assessed the dietary phytochemical index in relation to the risk of breast cancer in women. This case-control study was conducted on 100 incident breast cancer cases and 175 healthy controls. Data regarding socio-demographic factors, medical history, medications, and anthropometric measurements were collected. Dietary data were obtained using a validated food frequency questionnaire and a energy-adjusted dietary phytochemical index (PI) was calculated. The odds ratios of breast cancer were assessed across energyadjusted PI quartile categories. The mean age of participants was $46.2{\pm}8.9$ and $45.9{\pm}9.4$ years in cases and controls, respectively. The mean PI across quartile categories was $13.9{\pm}2.6$, $21.1{\pm}1.8$, $26.7{\pm}2.1$, $41.6{\pm}10.2$ in the first, second, third and fourth quartiles, respectively. After adjustment for all potential confounders, the risk of breast cancer in the forth quartile of dietary PI was significantly decreased (OR=0.08, 95%CI=0.01-0.84). Higher intake of phytochemical-rich foods is associated with lower risk of breast cancer.

Dietary Intake of Polyphenols and the Risk of Breast Cancer: a Case-Control Study
Bahrami Alireza,Makiabadi Elham,Jalali Saba,Heidari Zeinab,Assadi Mojan,Rashidkhani Bahram 한국임상영양학회 2021 Clinical Nutrition Research Vol.10 No.4
Despite mounting evidence that dietary polyphenols might have a protective role against the risk of breast cancer (BC), few studies have assessed the relationship between intake of polyphenol classes and subclasses with BC. Thus, we examined the relationship between dietary polyphenol classes and individual polyphenol subclasses and the risk of BC. Overall, 134 newly diagnosed BC patients and 267 healthy hospitalized controls were studied. Dietary intake was assessed using a validated 168-item food frequency questionnaire (FFQ). To estimate dietary intake of polyphenols, polyphenol content (flavonoids, lignans, stilbenes and phenolic acids) of 80 food items were derived from an updated version of the phenol explorer database containing information on the effects of food processing on polyphenol content. The dietary polyphenol intake was calculated by matching the subjects' food consumption data with our polyphenol content database. Multivariate logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Controls had higher intake of total polyphenol (marginally significant; p = 0.07), hydroxycinnamic acid (marginally significant; p = 0.05) and lignan (p = 0.01). After adjusting for potential confounders, high consumption of lignans (highest vs. lowest tertile: OR, 0.51; 95% CI, 0.26–0.97; p for trend = 0.04) associated with decreased risk of BC. There was no significant relationship between intake of other polyphenols and risk of BC. Our findings suggest that high lignan intake is associated with a reduced risk of BC.
