Cutting junk food may ease heart failure burden

This study looks at whether people with heart failure can reduce their intake of ultra-processed foods (like packaged snacks, sugary drinks, and fast food) and whether doing so improves their health. Participants will track their meals using a smartphone app and receive coaching on how to eat fewer processed foods. Researchers will also test blood and urine samples to find biological markers that show how much ultra-processed food a person has eaten. The goal is to see if this approach is practical and leads to better heart health.
