ABSTRACT
BACKGROUND AND AIMS: Dietary pattern and lifestyle have been reported to be significant risk factors in the development of coronary heart diseases (CHD). The contribution degree of these dietary risk factors in CHD development in non-westernized countries is unclear. This study aimed to evaluate several dietary choices and their potential association with CHD. METHODS AND RESULTS: A case-control study was conducted at Prince Hamza Hospital, a referral center for coronary angiography in Amman, Jordan. Four-hundred patients referring for elective coronary angiography with clinical suspicion of coronary artery disease were enrolled. Data was collected using interview-based questionnaires. Dietary patterns were derived using Principal Component Analysis. Multivariate logistic regression was used to estimate the relationship between dietary choices and CHD. Three dietary patterns were identified. The "Healthy Dietary Pattern", which presented a diet rich in olive oil, fruits, vegetables, legumes, whole grains, fish, and low meat intake, was associated with a significant decrease in the odds of CHD (OR = 0.53, 95% CI = 0.28-0.98). The "High-Fiber Pattern", which is mainly composed of legumes and bulgur, significantly reduced the odd of CHD (OR = 0.55, 95% CI = 0.27-0.92) for the fourth quartile compared to the first one. No significant association was found between CHD and the "Western Dietary Pattern", which is loaded with refined grains, sweets and deserts, sugary drinks, and deep fried foods. CONCLUSIONS: The "Healthy Dietary Pattern" and the "High-Fiber Pattern" were associated with a decrease in odds of CHD among Jordanians.

BACKGROUND: Data from several studies suggest that a diet high in meat, including processed meat and fat, may have an association with the development of colorectal cancer (CRC). METHODS: The present study aimed to investigate the relationship between meats, dairy products, fat consumption and the risk of CRC in Jordanians. A case-control study was performed at the five largest hospitals in Jordan. Dietary data were collected from 220 diagnosed cases of CRC and 281 healthy disease-free controls. The CRC cases were matched as closely as possible to controls using age, sex, occupation and marital status. RESULTS: The consumption of different levels and frequencies of several food types, including meats, chicken, milk and fish, was found to be associated with the risk of developing CRC. Added fats and oils were inversely associated with CRC risk with odds ratio = 0.33 (95% confidence interval = 0.13-0.83, Ptrend = 0.005). The predominant fat added by cases and controls was olive oil, followed by corn oil. CONCLUSIONS: The results of the study suggest that the consumption of some types of meat, processed meats and Labaneh (strained yogurt) may be associated with the risk of developing CRC.
