Physical activity information will be collected using short-IPAQ (International Physical Activity Questionnaire) and demographic information through a general information questionnaire. In order to evaluate dietary intake of patients in terms of energy(kcal/(day), carbohydrate(gr/day), protein(gr/day), fat intake(gr/day), SFA (Saturated fatty acids) (gr/day), MUFA (Monounsaturated fatty acids) (gr/day), PUFA (Polyunsaturated fatty acids)(gr/day), Vitamin E(mg/day), Vitamin C(mg/day), Beta-carotene(mg/day) and Sodium intake (mg/day), 24-hr recalls will be completed by interviewing the patient for 3 days (two normal days and a weekend da
