About this study

Official title: Evaluation of Boiled Water Extracts of Legumes Seed Coats for Alpha Amylase and Alpha Glucosidase Activity: Formulation of Anti- Diabetic Nutraceuticals

This open-label clinical trial aims to evaluate whether daily consumption of soup prepared from boiled water extracts of selected legume seed coats, seasoned with salt and spices, improves glycemic regulation in individuals with metabolic syndrome or type 2 diabetes mellitus (T2DM). The primary question is whether daily intake of this palatable legume-based soup enhances glycemic control. Secondary questions include whether it reduces dyslipidemia, oxidative stress, and inflammation in participants with metabolic syndrome or T2DM. Participants will consume the soup once daily for 30 consecutive days. Clinical assessments, including HbA1c, fasting blood glucose, lipid profile, and biomarkers of oxidative stress and inflammation will be conducted at baseline and after the 30-day intervention.

Read the detailed description

Type 2 diabetes mellitus (T2DM) is one of the leading metabolic disorders worldwide and is associated with increased morbidity and mortality. Elevated postprandial blood glucose levels are recognized as an important risk factor for the development and exacerbation of T2DM and its macro- and micro-vascular complications. The acute glucose fluctuations induce oxidative stress and systemic inflammation and fastens the disease progression. Most oral anti-diabetic medications (metformin, sulfonylureas, thiazolidinediones) lower basal blood glucose levels; nevertheless, for effective long-term glycemic control, postprandial hyperglycemia must also be effectively managed.

Alpha-glucosidase inhibitors (AGIs) are a unique group of oral anti-diabetic medications that help lower post-prandial glucose spikes. They work by blocking the alpha-glucosidase enzyme in the intestine, which normally breaks down complex sugars into glucose for absorption. Currently, a few FDA-approved AGIs-such as acarbose, miglitol, and voglibose-are used to manage type 2 diabetes (T2DM). These drugs have been shown to improve blood sugar control and reduce risks of heart disease. Clinical trials suggest that the efficacy of acarbose to manage blood sugar is comparable to metformin, and the combination of both drugs is even more effective. However, long-term use of acarbose is often limited by digestive side effects. This highlights the need for safer, more selective, and better-tolerated AGIs.

Legume seeds are rich in polyphenols, flavonoids, and dietary fiber, which are known to inhibit alpha-amylase and alpha-glucosidase activity. After screening commonly consumed legumes, our laboratory identified boiled water extracts of certain seed coats with strong alpha-glucosidase inhibition, as well as antioxidant and anti-inflammatory properties. We have developed a palatable soup using these extracts.

This open-label, pre-post clinical trial will test whether daily consumption of the soup improves blood sugar control in individuals at high risk, including those with metabolic syndrome and type 2 diabetes mellitus (T2DM). The study will also include healthy volunteers. Participants will consume the soup daily for one month. Primary outcomes will include changes in fasting blood glucose, HbA1c, and postprandial glucose levels, assessed at predefined time points. Secondary outcomes will examine changes in lipid profile (dyslipidemia), biomarkers of oxidative stress, and markers of systemic inflammation. This study builds on prior laboratory findings and seeks to translate them into a practical, palatable dietary intervention with potential relevance for the prevention and management of hyperglycemia and associated metabolic disorders.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Legumes seed soupDietary supplement

    The pre-processed seed coats of legumes (Vigna mungo or Macrotyloma uniflorum) are boiled to obtain extracts, combined with varying amounts of cooked cotyledons, and seasoned with salt and spices.

Open-label Pre-post Trial of Legume Seed Coat SoupExperimentalParticipants will consume 200 ml of legume seed coat soup daily for four weeks, excluding Sundays, with delivery scheduled between 10:00 and 12:00 noon. Anthropometric measurements and blood samples will be collected at baseline and after the four-week intervention, while capillary blood glucose will be assessed using a glucometer at baseline, two weeks, and four weeks.
