Dr. Chris Van Tulleken recently conducted a month-long experiment in which he consumed 80% of his calories from ultra-processed food. He shares his findings in his new book, Ultra-processed People. This shift towards ultra-processed foods is a recent phenomenon, with a majority of food products in the US being categorized as unhealthy. However, the long-term effects of consuming these foods are not yet fully understood.
During the experiment, Van Tulleken made several changes to his diet. He incorporated more snack foods, indulged in his childhood favorite cereals, consumed more soda, and replaced nutritious snacks with chips. In the evenings, he relied on convenience foods such as microwavable lasagna, fried chicken, and pizza. Ultimately, about 80% of his calories came from ultra-processed foods, which is surprisingly easy to achieve given the prevalence of these products in the market.
The experiment had a significant impact on Van Tulleken’s well-being. He gained weight and experienced negative effects on his gut hormones. Ultra-processed foods interfere with these hormones, leading to higher levels of hunger even after consuming enough calories. This suggests that these foods are designed to promote excessive consumption and may contribute to the rise of diet-related diseases like obesity and Type 2 diabetes.
The findings of Van Tulleken’s experiment align with the research conducted by scientist Kevin Hall and epidemiological evidence. These studies demonstrate that individuals consuming an ultra-processed food diet tend to consume about 500 additional calories per day compared to those on a whole food diet. There is also evidence suggesting that ultra-processed foods disrupt the body’s ability to regulate food intake.
Van Tulleken’s experiment serves as a starting point for further research. He and his colleagues are now conducting a larger study to investigate the effects of an ultra-processed versus minimally-processed diet. This study aims to gather more data and provide insights on how to help individuals reduce their consumption of ultra-processed foods.
Not everyone responds the same way to ultra-processed foods. Some individuals can consume them in moderation, similar to alcohol consumption, while others may find these foods more addictive. It is important to recognize these differences and understand that there is no one-size-fits-all solution to addressing the issue of ultra-processed foods.
Moving forward, governments can play a crucial role in regulating these products. Similar to how tobacco is treated, there should be limitations on the marketing of ultra-processed foods and changes in labeling to inform consumers of their negative health effects. While banning or heavily taxing these foods may not be feasible due to affordability concerns, governments can take steps to educate the public about the risks associated with consuming them.
In conclusion, Van Tulleken’s experiment sheds light on the potential dangers of consuming a diet high in ultra-processed foods. Further research is needed to fully understand the long-term effects, and governments should take action to regulate these products and promote healthier food choices.
