Study
Reducing Processed Foods Can Lower Heart Disease Risk in Canadian Adults
Eating fewer ultraprocessed foods could prevent up to 38% of cardiovascular disease cases in Canada.
Summary
In plain language
A recent study found that consuming fewer ultraprocessed foods, such as packaged snacks and fast foods, may significantly reduce the risk of heart disease and stroke among Canadian adults. The research estimated that between 23% and 38% of cardiovascular events in 2019 were linked to these foods. By cutting ultraprocessed food intake by 20% to 50%, thousands of new heart disease cases and related deaths could have been prevented. This finding suggests that making simple changes to your diet, like opting for fresh foods over processed ones, could have a big impact on heart health.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study used a comparative risk assessment model to analyze the impact of ultraprocessed food consumption on heart disease and stroke in adults over 20 in Canada.
Researchers looked at dietary data and health statistics to estimate how much cardiovascular disease is linked to ultraprocessed foods.
They found that reducing intake of these foods could prevent a significant number of new heart disease cases and deaths.
While the study used modeling and national data, it highlights the potential benefits of dietary changes.
Consider discussing with your healthcare provider how reducing processed foods in your diet might support your heart health.

Research Quality Score
Scored September 22, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study's score is limited by its retrospective design and lack of bias control. Statistical methods are standard but lack power analysis. Transparency is partial, with no pre-registration. The absence of financial disclosures affects the conflicts score. Relevance is partial due to the broad age range without specific focus on seniors. Journal quality is unassessable.

Conditions This Research Covers
These condition pages help connect the paper back to the real-world health concerns it addresses.
Heart Disease
Heart disease, also known as cardiovascular disease, is a broad term that encompasses a range of conditions affecting the heart and blood vessels. It is a leading cause of death worldwide, particularly among older adults.
Hypertension
Hypertension, often referred to as high blood pressure, is a common health condition characterized by elevated blood pressure. It is a significant risk factor for heart disease, stroke, and kidney disease. While hypertension can affect people of all ages, it is particularly prevalent among older adults.
Atrial Fibrillation
Atrial fibrillation, often called AFib, is a common heart condition that causes an irregular and often rapid heart rate. It primarily affects older adults, leading to symptoms like fatigue and shortness of breath. Managing AFib is crucial to reduce the risk of stroke and improve quality of life.
CVA (Stroke)
A stroke, or cerebrovascular accident (CVA), occurs when blood flow to a part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. This medical emergency is more common in seniors and can lead to significant physical and cognitive challenges.
