Clinical Trial Summary

There is a need to change eating patterns towards healthier diets with new sources of non-animal protein, obtained through more sustainable systems in line with strategies such as the European Green Deal, the "Farm to Fork" strategy, or the Common Agricultural Policy, among others. The objective of this study, is to evaluate the nutritional effect of the developed products and their impact on the improvement and/or prevention of health problems (diabetes, intestinal dysbiosis), as well as to design and evaluation of the effect on health of a vegetable protein-based nutraceutical that also includes fiber and resistant starch.


Description:

This study is designed as a 3-week, randomised, parallel study, focused on overweight/obese men and women between 20 and 65 years old. All participants attend the Nutrition Intervention Unit of the Center for Nutrition Research in the University of Navarra for 2 times during the intervention (day 1 and day 21). RECRUITMENT AND SCREENING: The recruitment and screening of participants will be carried out through a Google Form questionnaire and by a phone call. At the same time, the database of people interested in participating in nutritional studies of the Center for Nutrition Research will be used, who will be contacted by phone or email to offer them the study. In addition, the study information and the recruitment form will also be posted on the Center for Nutrition Research website for anyone who wants to enroll in the study. On the other hand, the study will be disseminated through the channels available in the University of Navarra (Unclic, Alumni, emails, etc.) and through the placement of informative posters in the different buildings of the University of Navarra, as well as in public and private centers in Navarra, with prior authorization. If it is necessary, the study will be disseminated in the media such as in press, radio and TV. The staff of the Nutritional Intervention Unit will assess the data provided by the potential participants and those who meet the inclusion criteria will be cited for the first visit of the study, which will take place in the Nutritional Intervention Unit of the Center for Nutrition Research in the University of Navarra. The information sheet and the informed consent will be sent to them beforehand so that they can read it for visit 1. CLINICAL INVESTIGATION DAY 1 (day 1): It will be carried out in groups of 10 people, who will attend the facilities of the University of Navarra fasting for at least 10 hours. The volunteers will be received by the nutritionist and the study nurse. Once gathered, proceed as follows: - Welcome, detailed explanation of the study procedures and resolution of doubts. - Delivery of the information sheet and the informed consents to the volunteers. - Those volunteers who want to participate will sign the informed consent. Then, the procedures for taking samples and data will begin. - Delivery of 2 kits for collecting stool samples (beginning and end). The sample collected at the beginning will be delivered within three days to the facilities of the Nutritional Intervention Unit. - Delivery of a food consumption frequency questionnaire and a gastrointestinal symptoms questionnaire. They will be filled out with the help of the nutritionist during the visit and will refer to the last 3 weeks. - Delivery of the VAS hunger-satiety questionnaire to be completed 1-2 days before the final visit. - The dietician-nutritionist will take the anthropometric measurements of the volunteers individually and with light clothing. - The nurse will draw blood (2 serum tubes of 5 mL). - Delivery of the nutraceutical under study or the control nutraceutical (see composition in Table 1) as well as indications for the three weeks of the study. The nutraceutical should be consumed daily for 3 weeks as a substitute for breakfast in both groups. - The date and time for the final visit (visit 2) will be specified. CLINICAL INVESTIGATION DAY 2 (day 21): It will be carried out in groups of 10 people, who will have to attend the University of Navarra fasting for at least 10 hours. The volunteers will be received by the nutritionist and the study nurse. Once gathered, proceed as follows: - Collection of stool samples and VAS hunger-satiety questionnaire. - General talk to welcome everyone and ask about the course of the 3 weeks. - The dietitian-nutritionist will take the anthropometric measurements of the volunteers individually and with light clothing. - The Food Frequency Questionnaire and the Gastrointestinal Symptoms Questionnaire corresponding to the final visit will be completed with the help of the nutritionist. They will refer to the 3 weeks that the intervention lasts. - The volunteer will complete the Nutraceutical Acceptance Questionnaire. - The nurse will draw blood (2 serum tubes of 5 mL).

Outcome

Type Measure Description Time frame Safety issue
Primary Change of fecal microbiota from baseline to week 3. Fecal microbiota of participants will be analyzed by bacterial 16S gene sequencing technology. The Time Frame contains two time points: Clinical Investigation Day 1 (at baseline) compared to Clinical Investigation Day 2 (after 3 weeks of intervention).
Secondary Change of weight from baseline to week 3 (weighing machine) Weight of participants in fasting condition will be analyzed by bioimpedance and reported in kg. The Time Frame contains two time points: Clinical Investigation Day 1 (at baseline) compared to Clinical Investigation Day 2 (after 3 weeks of intervention).
Secondary Change of body mass index from baseline to week 3. Body mass index will be calculated as follows: weight (kg)/ height (cm)2. The Time Frame contains two time points: Clinical Investigation Day 1 (at baseline) compared to Clinical Investigation Day 2 (after 3 weeks of intervention).
Secondary Height at baseline. Height of participants will be measured by stadiometer and reported in meters. The Time Frame contains one time point: Clinical Investigation Day 1 (at baseline).
