Healthy Effects of an Innovative Probiotic Pasta (SFLABPASTA)

October 30, 2018 updated by: Nicoletta Pellegrini, PhD, University of Parma
The aim of the project was the evaluation of the antioxidant and anti-inflammatory effects of a whole grain pasta, enriched in barley β-glucans and fortified with strains of Bacillus coagulans, versus a control wheat pasta on healthy volunteers, using a parallel randomized controlled trial.

Detailed Description

Epidemiological evidences indicate that consumption of whole grains products is associated to a decreased risk for common chronic diseases, as cardiovascular diseases, diabetes, obesity, hypertension and metabolic syndrome. In the present study a whole grain pasta was supplemented with prebiotics and probiotics 'ad hoc' formulated. In detail, pasta was industrially developed after the identification of particular cultivars of wheat and barley, rich in carotenoids, β-glucans (2.6 g/100g pasta), not soluble fibers and antioxidants. Further, pasta was supplemented with spores of Bacillus coagulans, a putative probiotic microorganism, belonging to Lactobacillus family. It is well demonstrated the ability of this microorganism to survive to technological processes and to upper gastro-intesinal tract, in order to exert beneficial effects in the lower gut, as anti-microbial activity, increasing immunological defences as well as improvements in intestinal regularity. Conversely, the control pasta was made from the same cultivar of grain and by the same technological process, but without any supplementation.

In this parallel randomized controlled one arm trial, 40 healthy volunteers were randomly allocated for the consumption of the two kind of pasta once a day, for 12 weeks. At the beginning of the study and every 4 weeks, subjects were asked to provide blood, urine and feces for the evaluation of:

  • blood inflammation markers;
  • blood lipid and carbohydrate profile;
  • blood and urine markers of cardiovascular risk;
  • feces profile of microbiota and detection of markers for the healthiness of the gut.

In addition, volunteers filled in different questionnaires regarding their dietary habits, the physical activity and the gut healthiness.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Variation of plasma lipids
Time Frame: 12 weeks

Measure of plasma concentrations (mg/dL) of Total-, LDL-, and HDL-Cholesterol; Measure of plasma concentrations (µg/mL) of Non Esterified Fatty Acids (NEFA), Esterified Fatty Acids (EFA) and Short Chain Fatty Acids (SCFA).

Statistical analysis of the primary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the primary outcome have been considered.

12 weeks
Variation of fecal microbiota composition
Time Frame: 12 weeks

By FISH (colony-forming unit, CFU/g).

Statistical analysis of the primary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the primary outcome have been considered.

12 weeks
Variation of antioxidant activity on fecal waters
Time Frame: 12 weeks

Measure of fecal waters FRAP (µmol/L) and TEAC (µmol/L) concentrations.

Statistical analysis of the primary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the primary outcome have been considered.

12 weeks

Statistical analysis of the secondary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the secondary outcome have been considered.

12 weeks
Variation of blood pressure
Time Frame: 12 weeks

Measure of blood pressure (mmHg).

Statistical analysis of the secondary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the secondary outcome have been considered.

12 weeks
Variation of body circumferences
Time Frame: 12 weeks

Measure of waist and hip circumferences (mm).

Statistical analysis of the secondary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the secondary outcome have been considered.

12 weeks
Variation of urine antioxidant marker
Time Frame: 12 weeks

Measurement of betaine in urine (mmol/L).

Statistical analysis of the secondary outcome was performed within and between each single intervention-arm. Further, a post-hoc subdivision of the study participants by means of a BMI or glycaemia cut-off value was applied, and statistical differences of the secondary outcome have been considered.
