Effects of Emulsification and Lipid Droplet Size on Postprandial Metabolic Responses
Study Overview

Conditions
Intervention / Treatment
Detailed Description
This study will be conducted using a randomized, crossover design with three dietary phases: 1) fine emulsion beverage (small lipid droplet size), 2) coarse emulsion beverage (large lipid droplet size) and 3) non-emulsified oil and water. All treatments will be consumed together with bread. All participants will be randomly allocated to the three test meals. Fifteen to twenty participants aged between 21 and 50 years will be recruited from the general public in Singapore.
During the testing sessions, participants' glycemic, insulinemic, lipidemic responses and gastric emptying to the test meals will be measured. Gastric antral distention ultrasound measurement is an indirect measure of gastric emptying rate. Participants' metabolic satiety for the test meals will also be assessed at regular intervals throughout the testing session. Each testing session will take approximately four hours in duration and the testing sessions will take place at least five days apart.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Fine emulsion
Emulsion with small lipid droplet size served together with white bread
|
Emulsion is made up of distilled water, olive oil and emulsifier.
Emulsion will be flavored, sweetened (sucralose) and served in a portion of 300ml and approximately 3 slices of white bread (50g of available carbohydrate).
Additional glass of plain water will be provided with every treatment.
|
EXPERIMENTAL: Coarse emulsion
Emulsion with large lipid droplet size served together with white bread
|
Emulsion is made up of distilled water, olive oil and emulsifier.
Emulsion will be flavored, sweetened (sucralose) and served in a portion of 300ml and approximately 3 slices of white bread (50g of available carbohydrate).
Additional glass of plain water will be provided with every treatment.
|
EXPERIMENTAL: Control
Non-emulsified oil and water served together with white bread
|
Beverage is made up of distilled water and olive oil.
Beverage will be flavored, sweetened (sucralose) and served in a portion of 300ml and approximately 3 slices of white bread (50g of available carbohydrate).
Additional glass of plain water will be provided with every treatment.
