Are processed foods and food dyes raising heart risk?

What's actually in it

Processed foods are often packed with more than just calories. They frequently contain a mix of chemical additives, synthetic food dyes, and even heavy metals. According to a 2026 review in Foods, the way these chemical mixtures interact in our bodies is a growing concern for safety regulators.

Beyond additives, these products can be contaminated with heavy metals, as noted in a 2026 study in Nutr Rev. Even our food supply chain is not immune to pollution, with a 2026 study in Environ Pollut finding that microplastics are entering the food web, creating a higher health risk for children.

What the research says

A 2026 study in Cardiol Rev confirms that processed foods and food dyes are directly linked to cardiovascular risk. These items are not just empty calories. They are active contributors to heart health problems.

The impact extends to metabolic health as well. A 2026 study in J Nutr found that reducing your intake of ultraprocessed foods can actually lower your risk of developing diabetes in midlife. This peer-reviewed research makes it clear that what you put in your kitchen pantry has a direct effect on your long-term health.
