Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Baseline blood glucose	Blood glucose levels before start eating the pasta dish in each clinical investigation day will be analyzed by biochemical autoanalyzer and reported in mg/dL.	0 min in the Clinical investigation day 1 and Clinical investigation day 2 (at least 7 days after the clinical investigation day 1)
Primary	Postprandial blood glucose	Blood glucose levels after start eating the pasta dish in each clinical investigation day will be analyzed by biochemical autoanalyzer and reported in mg/dL.	30, 60, 90, 120 and 150 min after start eating the pasta dish in the Clinical investigation day 1 and Clinical investigation day 2
Primary	Glycemia Area Under the Curve	Postprandial glycemia levels after eating pasta dish in each clinical investigation day will be analyzed biochemical autoanalyzer and reported in mg/dL. Glycemia AUC will be calculated by the trapezoidal rule.	Baseline, 30, 60, 90, 120 and 150 minutes in the Clinical investigation day 1 and Clinical investigation day 2
Secondary	Insulinemia Area Under the Curve	Postprandial insulin levels after eating pasta dish in each clinical investigation day will be analyzed by ELISA and reported in mU/L. Insulinemia AUC will be calculated by the trapezoidal rule.	Baseline, 30, 60, 90, 120 and 150 minutes in Clinical investigation day 1 and Clinical investigation day 2
Secondary	Baseline blood insulin	Blood insulin levels before start eating the pasta dish in each clinical investigation day will be analyzed by ELISA and reported in mU/L.	0 min in the Clinical investigation day 1 and Clinical investigation day 2
Secondary	Postprandial blood insulin	Blood insulin levels after start eating the pasta dish in each clinical investigation day will be analyzed by ELISA and reported in mU/L.	30, 60, 90, 120 and 150 min after start eating in the Clinical investigation day 1 and Clinical investigation day 2.
Secondary	Body weight	Weight of participants will be measured by bioimpedance and reported in kg	Clinical Investigation Day 1 (before eat the pasta dish) and Clinical Investigation Day 2 (before eat the pasta dish)
Secondary	Height	Height of participants will be measured by stadiometer and reported in m.	Clinical Investigation Day 1 (before eat the pasta dish) and Clinical Investigation Day 2 (before eat the pasta dish)
Secondary	Body mass index	Body mass index will be calculated as follows: weight (kg)/ height (cm)2.	Clinical Investigation Day 1 (before eat the pasta dish) and Clinical Investigation Day 2 (before eat the pasta dish)
Secondary	Acceptance of pasta dish	Pasta dish acceptance will be analyzed by acceptance questionnaire.	Clinical Investigation Day 1 (after eat the pasta dish) and Clinical Investigation Day 2 (after eat the pasta dish)
