Food Scientist Discusses Ultra-Processed Foods
A food scientist known for highlighting the connection between ultra-processed foods and chronic health issues has admitted he still consumes them, including what he calls “the bad ones.”
Dr. Kevin Hall was a nutrition and metabolism scientist at the National Institutes of Health (NIH) for over two decades before he resigned this spring, citing censorship of his work during the Trump administration.
In a recent interview, he shared insights into his eating habits, revealing he often opts for ultra-processed foods because they taste good and save time. “Just because something is ultra-processed doesn’t necessarily mean it’s bad for you,” he remarked.
For example, he mentioned using a low-sugar, low-sodium marinara sauce to make cooking easier—it’s simpler than preparing a sauce from scratch.
Interestingly, a 2019 study by Hall and his team found that consuming ultra-processed foods led participants to intake roughly 500 more calories each day compared to when they ate unprocessed foods, indicating a level of addiction.
Despite these findings, Hall treats ultra-processed foods more like indulgences. He mentioned he doesn’t eat breakfast, which some nutrition experts warn can lead to low energy or overeating later in the day.
However, Hall states, “I’m just not a breakfast eater,” preferring his morning to start with a cup of coffee instead.
His snacks around mid-morning usually consist of fruit, nuts, or hard-boiled eggs. Lunchtime, typically around 1 PM, is often leftovers from the previous night. He noted that marinara sauce plays a key role in his dinners and his favorite dish combines it with frozen scallops and whole-wheat pasta, alongside grilled vegetables.
For his children, he and his wife choose meals they know they will enjoy, as they are quite selective. While they do have healthy options like farmed Atlantic salmon and various vegetables, chicken nuggets are also a staple in their household.
Nutritionists generally recommend against ultra-processed options like chicken nuggets due to their potential association with various health risks, such as cancer and heart disease. These foods often have unhealthy levels of fat, sugar, and sodium but are appealing due to their convenience.
For Hall, chicken nuggets serve as a practical dinner option for his picky kids. “It can be a little challenging, but we make it work for the whole family,” he added.
Interestingly, ultra-processed foods have become increasingly common in the U.S., coinciding with rising obesity rates and other health-related issues.
These foods are typically high in fat, sugar, and sodium, often mass-produced with added colors and chemicals that aren’t typically found in home cooking. Items like sugary cereals, chips, frozen pizzas, and sodas fall under this category. Even seemingly healthier options like pasta sauce can be processed.
Research has shown negative health outcomes associated with ultra-processed foods, though it’s still unclear whether it’s the processing itself or other factors at play.
Following his earlier analysis, Hall initiated a more detailed multimillion-dollar study this year, where participants were compensated to spend 28 days studying these foods. As they consumed various diets, researchers monitored how processing affects digestion and metabolism.
Preliminary results from this ongoing study are intriguing, with earlier findings indicating that trial participants consuming a specific ultra-processed diet gained around 1,000 extra calories a day compared to those who had minimally processed foods. Adjustments to those food qualities led to reduced consumption even among ultra-processed options.
The National Institutes of Health allocates about $2 billion annually, around five percent of its budget, for nutrition research, as noted in Senate records.
