The Effects of Vegetable Preloading on Postprandial Glycemia, Insulinaemia and Gastric Emptying

Summary

The objective of this study is to investigate the importance of leavy vegetable preloading on the postprandial glycaemic and insulinemic response in human subjects when consumed a specific amount of digestible carbohydrate from Russet Burbank potatoes source.

Conditions

• Postprandial Hyperglycemia
• Insulin High

Interventions

OTHER

Co-ingestion

Subjects co-ingest both (300 g mashed potatoes) and (200 g baby round spinach supplemented with canola oil) in the same time.

OTHER

0 min preload

Subjects consume 200 g baby round spinach supplemented with canola oil first, then directly consume 300 g of mashed potatoes.

OTHER

5 min preload

Subjects consume 200 g baby round spinach supplemented with canola oil first, wait 5 minutes, then consume 300 g of mashed potatoes.

OTHER

10 min preload

Subjects consume 200 g baby round spinach supplemented with canola oil first, wait 10 minutes, then consume 300 g of mashed potatoes.

OTHER

15 min preload

Subjects consume 200 g baby round spinach supplemented with canola oil first, wait 15 minutes, then consume 300 g of mashed potatoes.

OTHER

20 min preload

Subjects consume 200 g baby round spinach supplemented with canola oil first, wait 20 minutes, then consume 300 g of mashed potatoes.

OTHER

Spinach only / 10 min preload

Subjects consume 200 g baby round spinach WITHOUT canola oil first, wait 10 minutes, then consume 300 g of mashed potatoes.

OTHER

Canola oil only / 10 min preload

Subjects consume 20 g of canola oil first, wait 10 minutes, then consume 300 g of mashed potatoes.
