Brief Summary

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

Resistant starch partially resists hydrolyzation by digestive enzymes in humans. Consequently, it is not absorbed in the small intestine and goes directly to the large intestine, where it is fermented by the intestinal microbiota, acting as a prebiotic and stimulating the growth of beneficial bacteria in the colon. In addition, the effect of resistant starch on postprandial glucose metabolism is studying. Thus, the present research on healthy subjects has been proposed.

The main objective is to assess the effect on postprandial glycemia of eating a pasta dish made with resistant starch versus its original version.

For this purpose, a randomized, double blind crossover study has been designed.

Target sample size is 18 subjects.

Detailed Description

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

The arms of the study are two:

* Experimental group (pasta dish made with resistant starch).
* Control group (original pasta dish).

Volunteers who wish to participate in the study will be interviewed by phone to verify that they meet the main inclusion criteria. Volunteers who meet the main inclusion criteria will be invited to an information and screening visit to resolve any doubts. Volunteers who agree to participate in the study will sign the informed consent and will be randomly assigned to one of the two arms of the study.

The two visits (clinical investigation days) of the study will take place with the volunteers in a fasting state of 4 hours and separated by at least 1 week washout period. The day before the visit, volunteers won't be able to drink alcohol, drink and eat excessively, and/or sleep few hours. Both visits will consist of eating a pasta dish in a maximum of 15 minutes. Blood samples will be taken before eating and during the 2.5 hours after (30, 60, 90, 120 and 150 minutes), in order to analyze the evolution of blood glucose and insulin levels.
