Gastrointestinal Tolerance, Satiation and Sensory Acceptance of Yogurts Containing Dietary Fiber and Coffee Cascara Extract

2018-06-03 22:30:14 | BioPortfolio


Coffee processing byproducts, such as coffee cascara (outer skin and pulp of the coffee berry), have potential health promoting properties due to the presence of bioactive compounds. Its use as a novel food ingredient is a means of valorizing this fractioin in the elaboration of functional yogurts. The addition of cascara extract in yogurt affects its texture quality. The addition of dietary fiber can help regain the structure of the yogurt's gel. However, secondary gastrointestinal effects associated with acute fiber ingestion must be considered.The aim of this clinical trial is to study the gastrointestinal tolerance, satiation and sensory acceptance of yogurts containing both coffee cascara extract and different doses of commercial soluble dietary fiber.


Forty healthy volunteers will be recruited and distributed into 4 groups following a randomized, blind, crossover design. Yogurt formulations will be administered two hours after the ingestion of a standardized breakfast, as a snack. Yogurt formulations include:

- Control cascara yogurt with 0% dietary fiber.

- Cascara yogurt with 3% dietary fiber.

- Cascara yogurt with 7% dietary fiber.

- Cascara yogurt with 13% dietary fiber.

The study will be conducted in 4 sessions, with at least 48h of washout period between treatment days. Data on gastrointestinal tolerance, satiation and sensory acceptance will be taken on the same day of the treatment using online surveys.

The Effect of Different Types of Dietary Fiber on Satiation

It has been suggested that dietary fibers can affect food intake and satiation. Satiation, or meal termination, can be induced by sensory properties and energy density of fiber-rich food p...

Repetitive Lipid Intake and Food Intake

In the present study we will investigate the effect of consuming lipids inside alginate gel once a day during 4 days on food intake and satiety feelings in healthy people with overweight. ...

Yogurt for Prevention of Chronic Inflammation

The objective of this study is to conduct a randomized cross-over dietary intervention in obese adult women to compare how yogurt and a control food affect biomarkers of inflammation and i...

Gastrointestinal Tolerability Following Multiple Servings of a Novel Dietary Fiber

The study will assess the gastrointestinal tolerability of multiple servings of a novel dietary fiber at three different dose levels in generally healthy men and women. Double-blind contro...

Dietary Fiber in Severely Obese Children - Pilot

The purpose of this pilot study is to assess the feasibility of a 3-month dietary fiber intervention: 1) engaging adolescents in regularly consuming a dietary fiber preparation (psyllium p...

Long-term dietary fiber intake and risk of chronic obstructive pulmonary disease: a prospective cohort study of women.

Until now, only two prospective cohort studies have investigated dietary fiber intake in relation to risk of chronic obstructive pulmonary disease (COPD), but neither examined long-term fiber intake. ...

Small food texture modifications can be used to change oral processing behaviour and to control ad libitum food intake.

Little is known whether small modifications of food texture are sufficient to influence satiation. This study used four iso-caloric yogurts differing in viscosity (low/high) and granola particle size ...
