Trial Summary

What is the purpose of this trial?

The primary goal of this research is to evaluate the effect of daily whole-cooked chickpea and lentil consumption for 8-weeks on gut health, including microbiome-metabolome arrays and gut epithelial/barrier function, in healthy young adults. Secondary Objectives include: * To examine the effect of daily whole-cooked chickpea and lentil consumption for 8-weeks on the measures of metabolic health and inflammation in healthy young adults. * To determine the feasibility of healthy young adults to successfully incorporate and sustain the recommended daily intake of pulses into their diets for eight consecutive weeks Research Interventions: Participants will be asked to consume a normal diet supplemented daily with either A) whole-cooked canned lentils, or B) whole-cooked canned chickpeas. The control condition will be instructed to consume a normal diet while restricting all pulse intake throughout the study.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you have been taking antibiotics or pre/pro/postbiotics in the last 3 months, you would not be eligible to participate.

What data supports the effectiveness of the treatment Whole-cooked Chickpeas, Whole-cooked Lentils for Imbalance of Microbes?

Research shows that diets supplemented with chickpeas can positively change the gut bacteria in healthy adults, potentially promoting intestinal health. Additionally, chickpea supplementation in mice reduced inflammation and improved gut health, suggesting that chickpeas may help balance gut microbes.12345

Is it safe to consume lentils and chickpeas for gut health?

Chickpeas and lentils are generally safe for most people, but some individuals may experience allergic reactions, such as asthma or other allergic responses, when exposed to them. It's important to be aware of any personal allergies before consuming these legumes.13678

How does the treatment of whole-cooked chickpeas and lentils for microbial imbalance differ from other treatments?

This treatment is unique because it uses whole-cooked chickpeas and lentils, which are natural foods rich in dietary fiber, to help balance gut microbes. Unlike other treatments that might involve medications or supplements, this approach leverages the natural properties of these legumes to promote a healthier gut microbiome, potentially improving intestinal health without the need for synthetic interventions.1891011

Treatment Details

Interventions

  • Whole-cooked Chickpeas
  • Whole-cooked Lentils
Trial Overview The study tests how eating canned chickpeas or lentils every day for 8 weeks impacts gut microbiome and metabolic health compared to a normal diet without pulses. It aims to see if these foods can improve gut function and reduce inflammation.
Participant Groups
3Treatment groups
Experimental Treatment
Active Control
Group I: Lentil ConditionExperimental Treatment1 Intervention
The lentil condition (LEN) includes a normal diet supplemented weekly with whole-cooked canned chickpeas for 8 weeks (Goya Foods - 80 kcals, 3g fiber, 6g protein per ½ cup). The required intake of chickpeas is determined by stepwise progression of intake according to DGAs 2020-2025 and the participant's gender. Instructions for intake will be provided specifically for each participant and for each week of the study. LEN participants will receive workbooks that contain weekly adherence checklist (dosing diaries), conversion measurements, and copies of RD-prepared recipes outlining various ways to incorporate chickpeas/lentils into their diets each week as meals and/or snacks.
Group II: Chickpea ConditionExperimental Treatment1 Intervention
The chickpea (CHK) condition includes a normal diet supplemented weekly with whole-cooked canned chickpeas for 8 weeks (Goya Foods - 120 kcals, 4g fiber, 6g protein per ½ cup). The required intake of chickpeas is determined by stepwise progression of intake according to DGAs 2020-2025 and the participant's gender. Instructions for intake will be provided specifically for each participant and for each week of the study. CHK participants will receive workbooks that contain weekly adherence checklist (dosing diaries), conversion measurements, and copies of RD-prepared recipes outlining various ways to incorporate chickpeas/lentils into their diets each week as meals and/or snacks.
Group III: Control ConditionActive Control1 Intervention
The control (CTL) condition will be instructed to consume a normal diet while restricting all pulse intake throughout the study. CTL will receive nutrition education materials in custom workbooks on what pulses are and how to avoid intake.

Findings from Research

Incorporating cooked navy bean powder into a high-fat diet for obese mice significantly improved intestinal health and reduced inflammation, as indicated by changes in the fecal microbiome and increased expression of intestinal health markers.
While switching to a low-fat diet also reduced body weight, it did not improve intestinal health or inflammation as effectively as the high-fat diet supplemented with beans, suggesting that beans can enhance health outcomes even in the context of an obesogenic diet.
