Protocol summary
Study aim
Examining The Effect of a New Developed Synbiotic Yogurt Consumption on Serum Inflammatory Biomarkers and the Expression of NF-κB and Lipid Metabolism Related Genes in Adults with Metabolic Syndrome
The intervention will be performed for 12 weeks on people with metabolic syndrome in health centers in Yasuj. People will be given 14 cans of yogurt once every two weeks, and patients will consume a 300-gram can of yogurt daily.The evaluation of variables is done at the beginning and end of the study by sampling the patient's blood.
Participants/Inclusion and exclusion criteria
Inclusion criteria: age between 30 and 50 years old, body mass index= 25-35 Kg/m2, the presence of at least three of the five components of the metabolic syndrome, and willingness to participate in the study. Exclusion criteria: weight changes of more than 10% in the last six months, change in the amount of sports activity, pregnant, lactating, and postmenopausal women, allergy to dairy products and probiotics, smoking and alcohol consumption, routine consumption of probiotic or synbiotic products, suffering from various diseases, taking certain medications such as antibiotics, anti-diabetics, and lipid-lowering drugs, uncontrolled blood pressure, consuming probiotic supplements.
Intervention groups
The subjects in the intervention group will receive 300 g/day of synbiotic yogurt containing Lactobacillus Plantarum, Lactobacillus pentosus (2˟108 CFU), and the yeast Kluyveromyces marxianus and 3% of natural plants (mountain celery, shallot, chicory, and mint) for 12 weeks. The control group will consume 300 g/day of regular yogurt. Yasuj Pasteurized Milk Company will provide the yogurts.
Main outcome variables
Serum Inflammatory Biomarkers and the Expression of NF-κB and Lipid Metabolism Related Genes

Randomization (investigator's opinion)
Randomized
Randomization description
First, we will use the Stratified Permuted Block Randomization method for patients who meet the inclusion criteria for random distribution in the intervention and control groups. First, they are classified in terms of gender (male/female) and body mass index level (from 25–29.9 and 35–30) and are placed in double blocks using the randomization method with sizes 2 and 4 (from the special table). used for randomization). Accordingly, each person may have four states. Then, people with the same conditions are randomly divided into intervention and control groups. In order to randomly assign both people to one of the groups, each person will be given a code, and these codes will be poured into a pot. An out-of-study person will then be asked to draw the codes out of the pot using a lottery. The person with the first code issued will be assigned to the intervention group and the other person to the control group. This process will be done in the same way for both people with the same condition.
Blinding (investigator's opinion)
Double blinded
Blinding description
Patients enrolled in this study will be unaware of whether they are in the normal yogurt group or in the synbiotic yogurt group. On the other hand, due to the similarity of the appearance of both products, which are given to the participants in packages with the same appearance and the same label, an attempt has been made to blind the patients. Also other people who participate in other stages including the researchers , the outcome evaluators, the analysts are blind to the study, and the third independent person is responsible for prescribing and secretly recording our type of prescription, and the other person is responsible for collecting data. The data analyzer also announces the results according to groups A and B. The drug evaluator also does not know the type of yogurt prescribed for each patient.
