Investigating the Glycaemic and Satiating Capacity of PulseOn® Enriched Foods
This study aims to understand if eating special crackers for breakfast, made with a unique pulse flour called PulseOn, can change how quickly your blood sugar rises and how satisfied you feel. We'll measure your hunger and fullness levels for several hours after breakfast and then see how much you choose to eat at a free-choice lunch on the same day. PulseOn flour is different because of how it's made, keeping whole plant cells intact, which might help with managing blood sugar and appetite. We're looking for healthy people to take part and help us learn more about potential benefits of these special crackers.
At a glance
What is this study about?
Imagine you're trying to choose healthier foods that help you feel full for longer and stop your blood sugar from spiking too much after a meal. This study is looking into a new kind of flour, called PulseOn, which is made entirely from pulses (like peas, beans, and lentils). What's special about PulseOn is the way it's processed, which keeps tiny plant cells whole. Early research suggests that this might mean foods made with PulseOn could affect your blood sugar differently and even help you feel more satisfied after eating.
In this study, we want to see if having crackers made with this special PulseOn flour for breakfast changes two important things: first, how your body handles sugar (your 'blood sugar response') and second, how hungry or full you feel. We'll be comparing these crackers to regular wheat flour crackers to see if there's a difference. We're also interested in whether eating the PulseOn crackers for breakfast affects how much you eat at lunchtime.
The findings from this research could be really important. If PulseOn flour helps to keep blood sugar more stable and makes people feel fuller, it could be a useful ingredient for creating healthier foods. This might particularly interest people who are looking for ways to better manage their appetite or blood sugar levels through their diet. It's a step towards understanding how new food technologies can improve everyday meals.
Key takeaways
- The study investigates how new PulseOn flour affects blood sugar and appetite.
- Participants will eat specific crackers and have blood sugar and hunger levels monitored.
- The research involves two visits and aims to understand how food choices impact feeling full.
- Findings could help develop healthier foods for blood sugar and appetite management.
- Healthy adults without certain medical conditions are needed.
Who may be eligible?
To join this study, you need to be at least 18 years old and in good general health, meaning you don't have any serious ongoing medical conditions. We're looking for volunteers who don't smoke or use recreational drugs.
There are some reasons why you might not be able to take part. For example, if you're pregnant or breastfeeding, or if you have a known food allergy or intolerance. We also can't include people who are on a restrictive diet to lose weight, or have lost a lot of weight recently, or if you have certain health problems like a blood clotting disorder, a pacemaker, or a disease affecting your digestive system.
Also, if you're a vegetarian or vegan, or if you're an elite athlete, this study might not be suitable for you. We also need to check your eating habits to make sure you're not a 'restrained eater', which means someone who strictly controls what they eat.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you currently smoke or use recreational drugs?
- Are you pregnant or breastfeeding?
- Do you have any food allergies or intolerances?
- Are you on a strict diet to lose weight or have you lost a lot of weight recently?
- Do you have a pacemaker or a disease affecting your digestive system?
What does participation involve?
If you decide to take part, you will need to visit us twice. On your first visit, we'll take some basic measurements like your weight, height, and waist size. We'll also take a small blood sample to check your blood sugar and ask you some questions about how hungry or full you feel.
Then, you'll eat a specific breakfast, either crackers made with PulseOn flour or regular wheat flour crackers. For the next four hours, we'll repeat those blood sugar checks and questions about hunger at different times. After four hours, you'll be given a lunch of pasta and tomato sauce and asked to eat until you feel comfortably full. The whole process for each visit will take several hours. You won't need to take any medication for this study, and there's no long-term follow-up after your second visit.

Common questions
What is PulseOn flour?
PulseOn is a special flour made from pulses, like beans and lentils, using a unique process that keeps tiny plant cells whole. We're studying if this makes it better for blood sugar and feeling full.
Will I know if I'm eating PulseOn crackers or regular crackers?
No, this is a 'blinded' study, meaning you won't know which type of cracker you're eating at the time. This helps ensure the results are fair.
How many times will I need to visit?
You will need to visit our centre twice for the study measurements.
Will I get paid for taking part?
The information provided does not state if participants will be compensated. You should ask the study team about this.
What happens with my personal information?
Your personal information will be kept confidential and used only for this research, typically by assigning you a study code instead of your name.
