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.
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.

In the Mediterranean diet; The frequency of consumption of foods such as olive oil, olives, nuts, fish, vegetables and fruits will be given in accordance with the Mediterranean diet pyramid. During the study, it is planned to develop new recipes suitable for the nutritional habits of the individual. The researcher will be able to reach the researcher 7/24 in case of any problem experienced by the individual, and the participant's questions will be answered. Nutrition counseling to this group will be supported by an oral explanation given by the dietitian.
Participants will take a daily supplement of 1600 mg of curcumin. It is planned that the participants will use 120 capsules of curcumin supplement during the research.

Inflammatory Bowel Disease Questionnaire (IBDQ)
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.
Time frame: Change from baseline Inflammatory Bowel Disease Questionnaire total score at 8 weeks
Mediterranean Diet Assessment Tool (14-MEDAS)
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).
Time frame: Change from baseline Mediterranean Diet Assessment Tool total score at 8 weeks
36-Item Short Form Survey (SF-36)
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.
Time frame: Change from baseline physical function, physical role limitation, pain, general health, vitality, social function, emotional role limitation, and mental health scores at 8 weeks
Truelove-Witts Severity Index
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.

Body Mass Index
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.
Time frame: Change from baseline BMI at 8 weeks
Waist Hip Circumference Ratio
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).
Time frame: Change from baseline Waist hip circumference ratio at 8 weeks
Daily energy intake
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 energy intake(kcal) will be calculated.
Time frame: Change from baseline from the daily energy intake at 8 weeks

24 Hour Recall Physical Activity Record
Individuals who will participate in the research will be asked to record the physical activities they have done within 24 hours, in minutes, and to bring them to the week in which nutritional counseling will begin. 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.
