Efficacy of Pigmented Rice on Reducing Cardiometabolic Risk Factors Among Filipino Adults

Efficacy of Pigmented Rice on Reducing Cardiometabolic Risk Factors Among Filipino Adults

The primary purpose of this clinical trial is to investigate whether the consumption of pigmented rice (black rice) in the diet improves cardiovascular health, specifically body weight, lipids, and glucose levels. It also aims to know whether people enjoyed eating pigmented rice and if they would continue eating it.

The goal of this clinical trial is to test if pigmented rice consumption can lower the cardiometabolic risk factors of adults. The main question[s] it aims to answer are:

• Will pigmented rice significantly reduce lipid levels compared to white rice after six weeks?
• Will pigmented rice significantly reduce glucose levels compared to white rice after six weeks? Will pigmented rice significantly reduce weight and waist-hip ratio levels compared to white rice after six weeks? What are the participants' experiences in consuming pigmented rice?

Participants will consume black-pigmented rice for six weeks while maintaining their usual physical activity. Researchers will compare the white rice group and the black rice group to see if lowers cardiometabolic risk factors.
