Are the foods we eat making us sick? During a Senate hearing, Senator Robert F. Kennedy Jr. pointed to highly processed foods as a major contributor to the rising rates of chronic diseases like obesity, diabetes, and heart conditions. He argued that fixing America’s food supply should be a top priority.

But what does the science actually say? Researchers have found strong connections between diets high in ultra-processed foods and a variety of health issues, including heart disease, cancer, and gastrointestinal problems. However, not all processed foods are bad—some are harmless or even beneficial. While diet plays a significant role, chronic diseases are often influenced by a mix of factors, including genetics and lifestyle.

Kennedy specifically called out artificial food dyes and other chemical additives, suggesting they need closer scrutiny. While some artificial dyes, like Red Dye No. 3, have been linked to cancer in animals, evidence in humans is less clear. However, experts agree that more research and oversight of food additives could help improve public health.

For now, the conversation continues. With chronic diseases on the rise, the push for a cleaner, healthier food supply is gaining momentum. What changes might be on the horizon? Only time will tell.
