Millet-based Muffins, Glycaemic Response, Insulinemic Response and Gastric Emptying
The Effect of Millet-based Muffins on Glycaemic, Insulinemic Response and Gastric Emptying in Pre-diabetic Adults
Millet is a functional grain that has attracted the attention of scientists for many years due to its significant benefits to human health. Research has shown that millets have a high antioxidant capacity and polyphenol content which can contribute to a reduced risk of some chronic diseases such as type 2 diabetes and its complications. This study aimed to assess the glycaemic response (GR), insulinaemic response (IR) and gastric emptying (GE) after the consumption of millet-based muffins in pre-diabetic and healthy participants.
This was a single-blind, randomized controlled crossover study in which participants consumed one control muffin (wheat) and one test muffin (millet). During each session, participants were required to consume either the test or the control muffin, consuming the alternative on the next visit. Then, 10 finger-prick blood samples were taken for the determination of glucose and insulin over 4 hours. 13Carbon (13C) sodium acetate was added to the muffins (control and test) in order to measure gastric emptying from the breath samples collected.

Detailed Description
This study aimed to assess the glycaemic response (GR), insulinaemic response (IR) and gastric emptying (GE) after the consumption of millet-based muffins in pre-diabetic and healthy participants. This was a single-blind, randomized controlled crossover study in which participants consumed one control muffin (wheat) and one test muffin (millet).This study investigated the effect of polyphenol-rich millet-based muffin on glycaemic response (GR), insulinaemic response (IR) and gastric emptying (GE) in healthy and pre-diabetic participants (people with prediabetes have blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes - the normal fasting blood glucose level is below 6.1 mmol/l or 108 mg/dl).
After potential participants have read the Participant Information Sheet (PIS) and signed the consent form, they were screened during the first visit to measure fasting blood glucose (FBG; fasting blood glucose should be between 6.1 to 6.9 mmol/l for pre-diabetic participants and < 6.1 mmol/l for healthy participants ).If eligible for the study, body weight and height and blood pressure were taken in the Functional Food Centre (currently known as Oxford Brookes Centre for Nutrition and Health). If the fasting blood glucose test was less than 6.1mmol/l (participants were informed of their fasting blood glucose result and given the choice either to do Oral glucose tolerance test (OGTT) to check for Impaired Glucose Tolerance (IGT), participate in the healthy group or to be excluded). If the participant agreed to continue and had one or more of the pre-diabetes inclusion criteria, they could complete an oral glucose tolerance test (OGTT) over 2 hours.( An oral glucose tolerance test involves taking a fasting sample of blood and then taking a very sweet drink containing 75g of glucose. After having this drink participants had to stay at rest until a further blood sample is taken after 2 hours.) If their 2 h blood glucose result was between 7.9 to 11.0 mmol/l, they were considered eligible to participate in the study as a prediabetic participant, and were asked to come for a subsequent visit in order to begin the study. If the participant does not have IGT, they had the option to take part in the study as a healthy participant.
