NCT04759625

Brief Summary

The purpose of the study is to assess the effect of dietary intervention that includes the daily consumption of a novel biscuit (enriched with the selected mushrooms rich in β-glucans) on gut health related parameters of healthy subjects over 60 years old.

Outcome Measures

Primary Outcomes (2)

  • Change from baseline in Gastrointestinal tolerance of novel biscuit during the interventional period and at 3 months.

    Gastrointestinal (GI) symptomatology will be recorded through a 7d-questionnaire in certain time periods.The intensity of each GI symptom (abdominal pain, distension, flatulence and borborygmi) will be measured daily on a scale of 0-4, where '0' represents absence of symptoms and '4' severe symptoms. The possible range for each weekly symptom score is 0-28, and for the total symptom score 0-112. Frequency and consistency of evacuations will be also noted, and presence of diarrhoea will be defined.

    Gastrointestinal symptoms will be evaluated at baseline, during and at the end of each intervention. (3 months period)

  • Change from baseline to the effect on the intestinal microbial populations and their metabolic products [i.e. Short-Chain Fatty Acids (SCFA)] (prebiotic effect) at 3 months.

    Microbial populations will be quantified with 16SRNA sequencing and quantitative Polymerase Chain Reaction (PCR). SCFAs will be quantified with Gas chromatography.

    The levels of microbial populations and their metabolic products e.g. SCFA will be measured at baseline and at the end of each interventional period.(3 months period)

Secondary Outcomes (6)

  • Change from baseline in Metabolic health at 3 months.

    Metabolic health will be measured at baseline and at the end of each interventional period.(3 months period)

  • Change from baseline in blood serum Insulin at 3 months.

    Blood serum Insulin will be measured at baseline and at the end of each interventional period.(3 months period)

  • Change from baseline in blood serum 25-hydroxy vitamin D at 3 months.

    Blood serum 25-hydroxy vitamin D will be measured at baseline and at the end of each interventional period.(3 months period)

  • Change from baseline in blood serum Parathyroid Hormone at 3 months.

    Blood serum Parathyroid Hormone will be measured at baseline and at the end of each interventional period.(3 months period)

  • Change from baseline in Immune system reinforcement at 3 months.

    Immune system reinforcement will be measured at baseline and at the end of each interventional period.(3 months period)
