Detailed Description

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

The nutritional pre-study had the following key objectives:

Primary objective:

\- Lupin protein lowers the postprandial blood glucose level equivalent to or to a greater extent than whey protein.

Secondary objective:

\- Lupin protein has an equivalent or a stronger insulinotropic effect than whey protein.
