About this study

In plain language

This study tests whether a guided plan to eat fewer ultra-processed foods is practical and how it affects the body. It is for adults with heart failure, a condition in which the heart does not pump blood well. The study uses the Cronometer food-tracking tool and blood and urine tests to track food intake.

Emerging evidence links ultra processed foods (UPFs) to adverse cardiovascular outcomes. UPFs are often high in sodium, unhealthy fats and added sugars, while being low in essential nutrients and fiber. UPFs contribute to systemic inflammation, fluid retention, and metabolic dysfunction-key drivers of HF and kidney disease progression. Traditional dietary counseling often lacks specificity around food processing levels. Furthermore, the majority of nutrition studies relied on extensive self-reported dietary recall food frequency questionnaires (FFQ) that are subjective, often labor intensive, and difficult to implement practically in the clinical setting. As such, researchers have developed metabolite scores from blood and urine samples to help quantify UPF consumption, which has the promise to better guide dietary counseling and track process. Therefore, the aim of this study is to evaluate the feasibility and physiological impact of a structured UPF-reduction dietary intervention in patients with HF, leveraging both digital dietary tools (Cronometer) and biomarker assessments.

Eligibility

Who can join

  • Age 18 or older.
  • Have NYHA Class II–III heart failure, meaning symptoms limit physical activity.
  • Can use Cronometer to track what you eat.
  • Can prepare food at home on your own and change what you eat.

Who can't join

  • Have had a heart transplant or an LVAD implant, a device that helps the heart pump blood.
  • Cannot or do not want to follow coaching to eat fewer ultra-processed foods.
  • Have an eGFR below 30, a test result showing how well your kidneys filter blood.

Simplified for readability. The official criteria below are what the study team uses.
