This study is being conducted to determine the digestibility of and available energy from pulses.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Previous studies have demonstrated that the metabolizable energy (energy available to the body) from tree nuts is less than predicted by the Atwater factors (the standard approach to determining calorie value of a food). The Atwater approach is over 100 years old and is inaccurate for some foods. This study will be conducted to determine the metabolizable energy from two pulses, lentils and chickpeas. The study will be a human nutrition intervention involving consumption of a controlled diet followed by collection of urine and feces.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

25 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Inclusion Criteria:

  • BMI between 19 and 38 kg/m2
  • Age 25 to 75 years during intervention

Exclusion Criteria:

  • Known (self-reported) allergy or adverse reaction to study foods
  • Women who have given birth during the previous 12 months or who are pregnant/lactating or who plan to become pregnant during the study
  • History of bariatric surgery or nutrient malabsorption disease (such as celiac disease), Crohn's disease, diabetes, or metabolic disorders that may interfere with the study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Energy excreted in feces and urine
Time Frame: Cumulative from day 10-17
Energy (units of calories) excreted in feces and urine will be determined by bomb calorimetry.
Cumulative from day 10-17
Energy excreted in feces and urine
Time Frame: Cumulative from day 39-46
Energy (units of calories) excreted in feces and urine will be determined by bomb calorimetry.
Cumulative from day 39-46
Energy excreted in feces and urine
Time Frame: Cumulative from day 57-64
Energy (units of calories) excreted in feces and urine will be determined by bomb calorimetry.
Cumulative from day 57-64

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Nitrogen excreted in feces and urine
Time Frame: Cumulative from day 10-17, day 39-46, day 57-64
Nitrogen (g) excreted in feces and urine will be measured.
