Effects of Plant Polar Lipids on Glucose Tolerance

Anne Nilsson17 enrolled

Overview

In this randomized controlled trial, two different plant polar lipids are investigated with respect to their potential to affect acute and second meal glucose tolerance and appetite sensations. The effects are compared with a common non-polar commercial oil. The lipids are consumed spread on a white wheat bread. A white wheat bread without added lipids is included as a control product. The test products are consumed at breakfast, and test variables are investigated in the postprandial period after the test breakfast and also after a second meal standard lunch.

Outcomes

Primary Outcomes

Blood glucose concentration (glucose tolerance)

Test products will be consumed at breakfast. Blood glucose will be determined repeatedly after the breakfast and also following a standardised lunch. The primary outcome measures for glucose concentrations are incremental areas under the curve after the test breakfast and after the standardised lunch

Time frame: 5.5 hours. Fasting (time =0), 15 minutes, 30 minutes, 45 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes, 210 minutes, 225 minutes, 240 minutes, 255 minutes, 270 minutes, 300 minutes, and 330 minutes.

Secondary Outcomes

Serum insulin concentrations

Test products will be consumed at breakfast. Insulin will be determined repeatedly after the breakfast and also following a standardised lunch. The primary outcome measures for insulin are incremental areas under the curve after the test breakfast and after the standardised lunch

Time frame: 5.5 hours. Fasting (time =0), 30 minutes, 45 minutes, 60 minutes, 90 minutes, 120 minutes, 150 minutes, 180 minutes, 210 minutes, 240 minutes, 255 minutes, 270 minutes, 300 minutes, and 330 minutes.

Subjective hunger sensations

Test products will be consumed at breakfast. Subjective appetite variables will be determined repeatedly after the breakfast and also following a standardised lunch. The secondary outcome measures are areas under the curve after the test breakfast and after the standardised lunch. Subjective appetite variables will be determined using a 100 mm Visual Analogue Scale (VAS).

Subjective satiety sensations
