Effects of Yogurt With Spirulina on Cardiometabolic Risk Markers

Status Completed

Clinical Trial Summary

The effects of yogurt with spirulina consumption compared to conventional yogurt (without spirulina) on several cardiometabolic and anthropometric parameters in individuals at risk of cardiovascular disease

Clinical Trial Description

This randomized, double-blind, controlled clinical trial aims to evaluate the effects of the consumption of yogurt with spirulina compared to conventional yogurt in high cardiometabolic risk volunteers. Volunteers must be overweight/obese either with prediabetes, and/or hypertension, and/or hyperlipidemia and following a Westernized-type diet. The participants will be divided and randomly assigned into 2 groups. Each participant will be instructed to consume two 200 g servings of their designated low-fat sheep yogurt daily before consuming the main meal. The intervention group will receive two spirulina-enriched yogurt desserts daily, which will provide a total of 4 g spirulina per day, while the control group will receive unfortified yogurt along with their usual Westernized-type diet. Participants in both groups will be instructed to consume the two yogurts (enriched or plain), either all at once or separately, before their main meals, along with their usual Westernized diet. No other dietary advice will be provided to participants. Participants will be asked to maintain their usual physical activity during the intervention period. At the beginning of the study, at 8 weeks, and 12 weeks after the beginning of the intervention (follow-up), blood samples will be collected after 12 hours of fasting. Two-hour oral glucose tolerance test (OGTT) will be performed using a continuous glucose monitoring system at the beginning and at 8 weeks. Blood lipids (total cholesterol, HDL-cholesterol, triglycerides, and LDL-cholesterol), CRP, IL-6, vitamin D, iron, ferritin, and total blood count will be measured at the beginning, 8 weeks, and 12 weeks. Anthropometric measurements (body weight and body composition analysis) will be performed at the beginning and every two weeks for 12 weeks. Basal metabolic rate (BMR) and central aortic blood pressure will be measured at the beginning, 4 weeks, 8 weeks, and 12 weeks of the intervention. Fecal samples will be collected and analyzed to study the gut microbiome composition at the intervention's beginning and at 8 weeks. ;
