Ultra-processed foods make up a large share of diets in countries such as Canada, the United Kingdom, and the United States, according to The Guardian.
These include ready meals, soft drinks, breakfast cereals, protein bars, and fast food.
According to the researchers, these products have become a regular part of everyday life for many people.
The study was conducted by researchers at the Université de Montréal and was published in the American Journal of Preventive Medicine.

The findings were also presented at an international obesity congress.
Researchers urge caution
Although the findings have attracted attention, several researchers believe they should be interpreted with caution.
The study is based on statistical estimates rather than direct measurements. As a result, further research is needed before it can be concluded with certainty that ultra-processed foods are a direct cause of heart disease.
The researchers behind the study also argue that responsibility does not rest solely with individual consumers.

They suggest that clearer food labeling and changes to marketing regulations could help improve dietary habits.
Could have a major impact on heart disease
The researchers estimate that between 23 and 37 percent of heart disease cases may be linked to a high intake of ultra-processed foods.
They also estimate that between 23 and 38 percent of deaths resulting from heart disease may be associated with this type of diet.
According to the researchers, reducing the consumption of ultra-processed foods could help prevent thousands of deaths in Canada, and they believe similar trends may apply to other high-income countries.
