Summary

Intake of foods high in carbohydrates causes a spike in glucose in the blood. Repeated high blood glucose spikes are associated with an increased risk of diabetes. People of black ethnicity have higher risk of diabetes. Vegetables may help in the regulation of blood glucose. Cowpea, also referred to as black-eyed peas (Vigna unguiculata) leaves, contain polyphenols and fibre that can help regulate blood glucose. The study will be an acute, single-blind, randomised control trial with a cross-over design involving healthy black participants aged ≥18 years. This clinical trial aims to investigate if consuming cowpea leaves can reduce blood glucose spikes after consuming a meal high in carbohydrates. Participants will be randomised to consume either bread with jam containing freeze-dried cowpea leaves (active intervention) or jam without any freeze-dried powder (control group). Blood glucose will be monitored before the intervention and every 15 minutes after the intervention using a continuous glucose monitor.
