Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Diet is the cornerstone treatment to manage blood sugar in people with Type 2 Diabetes (T2D). Fibres like guar gum and protein are macronutrients that have an effect in blood sugar levels. Mycoprotein is a fungi-based food high in both dietary fibre and protein shown to have a role in regulating blood sugar levels in healthy. However, little is known about the effects of mycoprotein on blood sugar levels in people with T2D. We are interested in South Asian because they have a different blood sugar response to the same food than a Caucasian.

The main aims of the study is to assess:

* The effect of mycoprotein in different formats (soup or mince) in blood sugar levels and appetite in South Asian and Caucasian with Type 2 Diabetes.
* The effect of the combination of mycoprotein with guar gum in different formats (soup or mince) in blood sugar levels and appetite in South Asian and Caucasian with T2D.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a double-blind crossover RCT. A total of 48 participants (24 Caucasian and 24 South Asian) with T2D and non insulin treated will be recruited. Participant will be randomly allocated to one of these two groups:

Group 1: Test food in form of soup and Group 2: Test food in form of mince. Once allocated in one of the groups, participant will consume in a random order 6 different test foods (soy, chicken, mycoprotein with and without guar gum) in a determined format (either as in soup or mince).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Mycoprotein as in Soup

24 will be randomised to soup (12 caucasian and 12 south asian) in order to test raw mycoprotein. Test food will be administrated orally and allowed 15 minutes for consumption at an even pace.

Group Type EXPERIMENTAL

Test food containing different types of dietary protein

Intervention Type OTHER

The test foods will be (in six study visits):

Soy mince/soup Chicken mince/soup Quorn mince/soup Soy mince/soup with guar gum Chicken mince/soup with guar gum Quorn mince/soup with guar gum

Mycoprotein as in Mince

24 will be randomised to mince (12 caucasian and 12 south asian) in order to test processed mycoprotein (Quorn). Test food will be administrated orally and allowed 15 minutes for consumption at an even pace.

Group Type EXPERIMENTAL

Test food containing different types of dietary protein

Intervention Type OTHER

The test foods will be (in six study visits):

Soy mince/soup Chicken mince/soup Quorn mince/soup Soy mince/soup with guar gum Chicken mince/soup with guar gum Quorn mince/soup with guar gum
