A large new cardiology study warns that diets heavy in ultra-processed foods are fueling a rise in heart attacks, strokes and fatal heart disease. The findings echo the latest Department of Health and Human Services guidance urging Americans to cut back on chips, candy and other packaged snacks.
Study finds clear link between ultra-processed foods and heart risk
Researchers tracked dietary patterns and cardiovascular outcomes and found a steady rise in risk with each extra serving of ultra-processed foods. Eating close to nine servings a day was tied to a 67% higher chance of heart disease compared with someone eating just one serving.

The analysis included common convenience foods such as packaged sweets, sugary drinks and many ready-to-eat items. Authors say the message is simple: more ultra-processed items, more heart risk.
Racial gap: Black Americans face a steeper climb in danger
The study intentionally examined diverse populations and uncovered unequal harms. For Black participants, each additional daily serving was associated with a 6.1% rise in the combined risk of heart attack, stroke and fatal heart disease.
By contrast, the corresponding increase in other racial and ethnic groups was about 3.2% per serving. That gap points to deeper social and environmental forces, researchers say.
Why the difference matters
Lead author Dr. Amier Haidar, a cardiology fellow at UTHealth Houston, linked the disparity to structural issues. Chronic stress, limited access to fresh food, and the concentration of food deserts in some neighborhoods amplify exposure to unhealthy products.
He also urged more research into biological pathways that might magnify harm in certain groups.
What counts as an ultra-processed food?
Ultra-processed foods often use industrial formulations. They are dense in calories and engineered for long shelf life and strong flavor. Examples include:
- Packaged snacks: chips, cookies, donuts
- Sugary drinks and many breakfast cereals
- Reconstituted meats and some ready meals
- Products with emulsifiers, synthetic dyes or other additives
Some packaged items can still offer value. Nutrition experts point to whole-grain breads, certain fortified plant milks and select plant-based alternatives as cases in point.
How processed foods harm the body
Scientists suspect multiple mechanisms. Ultra-processed diets can disrupt the gut microbiome. They can also trigger chronic inflammation. Both pathways are linked to cardiometabolic illness and some cancers.
High sugar, saturated fat and salt content further raise cardiovascular risk. Many additives are understudied for long-term health effects.
Money, marketing and addiction: why people eat these foods
Ultra-processed items are often cheap and calorie-dense. For households near or below the poverty line, affordability shapes choices.
Manufacturers also design some products to be highly palatable and habit-forming. That pattern compounds exposure in communities that already face limited options.
Practical steps to reduce intake and protect your heart
- Prioritize whole fruits, vegetables and minimally processed grains.
- Read labels for long ingredient lists and unfamiliar additives.
- Swap one packaged snack a day for a fresh option.
- Choose fortified packaged foods wisely—some can improve nutrition.
Public health officials say policy changes and improved access to fresh food are needed alongside personal choices to curb the toll of ultra-processed diets.
