Pulses for Heart Health
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether increasing pulse consumption (such as beans and lentils) improves heart health by examining cholesterol, blood sugar, and blood pressure. Participants will be divided into groups to consume either 1.5 cups or 3 cups of pulses per week, or to follow general healthy eating guidelines without additional pulses. The study also aims to determine if increased pulse consumption enhances overall diet quality and life satisfaction. It is ideal for individuals who currently consume less than 1.5 cups of pulses per week and are willing to modify their diet for 12 weeks. As an unphased trial, this study provides a unique opportunity to contribute to nutritional research and potentially improve heart health and well-being.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your healthcare provider.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that eating pulses, like beans and lentils, is generally safe for most people. Studies have found that pulses can lower the risk of heart disease. For instance, people who eat legumes four or more times a week have a 22% lower risk of heart disease compared to those who eat them less often.
Pulses are easy to digest and are part of heart-healthy diets. They can help improve cholesterol levels, which is important for heart health. These studies have not reported significant negative side effects from eating pulses, suggesting they are a safe addition to most diets.
For those considering joining a trial involving pulses, current evidence supports their safety and benefits in reducing heart disease risk factors.12345Why are researchers excited about this trial?
Most heart health treatments focus on medications or lifestyle changes like exercise and reducing salt. But researchers are excited about using pulses, like beans and lentils, for heart health because they are a natural food source rich in fiber, proteins, and essential nutrients. Unlike other treatments, introducing pulses into the diet offers a straightforward, food-based approach that may improve heart health naturally without the need for pharmaceuticals. The "Pulses 1.5 cups Group" and "Pulses 3 cups Group" focus on different intake levels, allowing researchers to explore how varying amounts can influence heart health. This trial could reveal how something as simple as adding more pulses to your diet might be a game-changer for heart health.
What evidence suggests that increasing pulse consumption could be effective for improving cardiometabolic risk factors?
Research has shown that eating more pulses, such as beans and lentils, can lower the risk of heart disease. For instance, individuals who consume legumes four times a week have a 22% lower chance of developing heart disease compared to those who eat them less than once a week. One study found that high legume consumption is linked to a 6% lower overall risk of heart-related issues. While these findings are promising, the benefits appear strongest for those who consume the most legumes. This trial will compare different levels of pulse consumption: one group will consume 1.5 cup-equivalents of pulses per week, while another group will consume 3 cup-equivalents per week. Increasing pulse intake might also improve cholesterol levels and reduce inflammation, both important for heart health.23467

What Are the Treatments Tested in This Trial?
Interventions
- Pulses
Trial Overview
The study tests the effects of consuming either 1.5 or 3 cups of pulses weekly, compared to following standard USDA My Plate nutrition guidelines, on heart disease risk factors like LDL cholesterol and blood pressure.
How Is the Trial Designed?
3
Treatment groups
Experimental Treatment
Active Control
Participants will receive an increased dose of 3 cup-equivalents of pulses per week. Similar to the first arm, they will participate in personalized nutrition education sessions and attend biweekly cooking classes and food demonstrations, all specifically designed to support a higher intake of pulses.
Participants will be prescribed a diet that integrates 1.5 cup-equivalents of pulses per week. They will receive tailored nutrition education, including one-on-one sessions with nutrition educators, focused on how to incorporate pulses into everyday meals. Biweekly cooking classes and food demonstrations will be provided to illustrate easy pulse-based recipes and methods of preparation.
Participants will continue with their habitual dietary practices without any prescribed increase in pulse consumption. This arm will receive general nutrition education sessions covering balanced dietary practices, but without any additional focus on pulse integration.
