- Brief Summary
The aim of the study was to examine and compare the effects of Mediterranean diet, curcumin supplementation with Mediterranean diet in individuals with ulcerative colitis, and resveratrol supplementation with Mediterranean diet in individuals with ulcerative colitis, on disease symptoms, quality of life, and inflammatory biomarkers.
- Detailed Description
In the light of the information in the literature, it is seen that the level of evidence in the existing literature is insufficient with the data obtained in terms of dietary approaches and nutritional supplements to be applied to individuals with Ulcerative Colitis (UC). In addition, when the literature was examined, no randomized controlled study was found that specifically examined the effects of the Mediterranean diet and nutritional supplements combined with diet in individuals with UC, and also compared the effects of two different nutritional supplements applied in combination with diet. In this direction, the aims of this research are;
* Mediterranean diet in individuals with UC,
* Curcumin supplement taken together with the Mediterranean diet in individuals with UC,
* Resveratrol supplement taken with the Mediterranean diet in individuals with UC, To examine and compare their effects on disease symptoms, quality of life and inflammatory biomarkers.
Hypotheses of the Research;
H0a: Mediterranean diet has no effect on disease symptoms, quality of life an inflammatory biomarkers in individuals with UC.
H0b: Curcumin supplementation in addition to the Mediterranean diet has no effect on disease symptoms, quality of life, and inflammatory biomarkers in individuals with UC.
H0c: Resveratrol supplementation in addition to the Mediterranean diet has no effect on disease symptoms, quality of life and inflammatory biomarkers in individuals with UC.
H0d: Three approaches including Mediterranean diet, curcumin and resveratrol supplements applied in addition to diet in individuals with UC; compared to each other in terms of disease symptoms, quality of life, and inflammatory biomarkers.

Group Intervention Description Resveratrol Supplementation Mediterranean Diet In addition to the Mediterranean Diet in the 1st group for individuals in this group; 250 mg resveratrol supplement (VeNatura Resveratrol Supplementary Food, Vefa, Istanbul, Turkey) will be given as 1 capsule each in the morning and evening meals. Mediterranean Diet Mediterranean Diet The individuals in this group will be given a nutrition model in accordance with the Mediterranean Nutrition Program under the supervision of a dietitian for 8 weeks. Individuals will be informed about the Mediterranean diet, their questions will be answered, the current food consumption record will be examined by the dietitian and they will be asked to follow the nutrition program prepared in the most appropriate way (by considering energy, nutrient requirements and nutritional habits). Every 15 days, the nutrition program will be updated with the meetings to be made by the dietitian and the patient, and the applicability of the program will be checked through daily communication.

- Primary Outcome Measures
Name Time Method Inflammatory Bowel Disease Questionnaire (IBDQ) Change from baseline Inflammatory Bowel Disease Questionnaire total score at 8 weeks The questionnaire consists of 32 questions and 4 subsections. These sections are; systemic symptoms (5 questions), emotional function (12 questions), social function (5 questions) and intestinal symptoms (10 questions). The questionnaire consists of a 7-point Likert scale system. For each question, 1 point indicates the highest level of exposure, and 7 indicates that there is no problem. Scores range from 32 to 224, with a higher score associated with higher quality of life. Turkish version of IBDQ will be used to assess patients' quality of life.
Mediterranean Diet Assessment Tool (14-MEDAS) Change from baseline Mediterranean Diet Assessment Tool total score at 8 weeks The Mediterranean Diet Assessment Tool will be used to measure the adherence of the participants to the Mediterranean diet. In the 14-question scale, 1 or 0 points are taken for each question asked according to the amount of consumption and these points are added. Scores are evaluated as ≤5 (low ), 6-9 (moderate), and ≥10 (high agreement).
- Secondary Outcome Measures
Name Time Method Body Mass Index Change from baseline BMI at 8 weeks Body weight measurements and height of the volunteers will be taken with height meter and scale. All measurements will be taken in light clothing and without shoes, according to International Standards for Anthropometric Assessment (ISAK) guidelines. Body mass index (BMI) will be calculated with weight (kg) / height (m)\^2 formula. Results will be interpreted as kg/m\^2.
36-Item Short Form Survey (SF-36) Change from baseline physical function, physical role limitation, pain, general health, vitality, social function, emotional role limitation, and mental health scores at 8 weeks It is the most frequently used quality of life scale in the medical field and consists of 8 sub-parameters with a total of 36 items that evaluate physical and mental health. These sub-parameters are physical function, physical role limitation, pain, general health, vitality, social function, emotional role limitation, and mental health. The scores range from 0-100, with 100 points indicating the best health condition and 0 points the worst health condition.
Daily protein, fat, carbohydrate and fiber intake Change from baseline from the daily protein, fat, carbohydrate and fiber intake at 8 weeks Food frequency will be evaluated by The Turkish Ministry of Health version of Food Frequency Questionnaire (FFQ). FFQ is a limited check list of foods and beverages with a frequency response section for subjects to report how often each item was consumed over the last three months. Food Record (FR) will be evaluated dietary recall. The patient will be asked to note down the foods she consumes for last 3 days. The obtained data from FFQ and FR will be entered into the BeBiS 7.1 software (BeBiS Comp., Istanbul, Turkey) and the daily protein, fat, carbohydrate, fiber (gram) intake will be calculated.

Waist Hip Circumference Ratio Change from baseline Waist hip circumference ratio at 8 weeks Non-stretchable tape measure will be used for waist and hip circumference. All measurements will be taken in light clothing and without shoes, according to International Standards for Anthropometric Assessment (ISAK) guidelines. Waist hip circumference ratio will be calculated with waist circumference (cm) / hip circumference (cm).

FFQ is a limited check list of foods and beverages with a frequency response section for subjects to report how often each item was consumed over the last three months. Food Record (FR) will be evaluated dietary recall. The patient will be asked to note down the foods she consumes for last 3 days. The obtained data from FFQ and FR will be entered into the BeBiS 7.1 software (BeBiS Comp., Istanbul, Turkey) and the daily energy intake(kcal) will be calculated.

Thus, after anthropometric measurements are made on the individuals, the resting metabolic rate (RMH) will be calculated with the Harris Benedict equation and the total energy requirements will be determined together with the physical activity coefficient found by using the 24-hour physical activity record.

Truelove-Witts Severity Index Change from baseline Truelove-Witts Severity Index score at 8 weeks Truelove-Witts Severity Index is a clinical classification categorizes the disease as mild, moderate, and severe, based on a combination of clinical and laboratory parameters, including bowel movements, rectal bleeding, fever, tachycardia, anemia, and increased sedimentation. The Truelove-Witts classification, using clinical symptoms, is applicable to patients with ulcerative colitis,and it is easy and reliable to use in the clinic.
