The choices we make daily have a profound impact on our health and increasingly, experts are pointing to diet as a central determinant of well-being. A growing body of evidence suggests that the modern American diet, characterized by ultra-processed foods, has not only contributed to a health crisis within the United States but has similarly been exported globally, impacting rates of chronic disease worldwide. Understanding the connection between food systems and health outcomes is becoming increasingly critical as we strive for longer, healthier lives.
A common misconception surrounding chronic illnesses is the belief that they are permanent and irreversible. However, Dr. Mark Hyman argues that many conditions, when addressed at their root cause, can be significantly improved or even reversed. “There are so many conditions people are living with that they believe are lifelong, but they don’t have to be,” Dr. Hyman stated in a ZOE podcast. “You can make changes that allow that to happen. I’ve seen it over and over again in my practice. It’s not just a theory.”
The Rise of Ultra-Processed Foods and Global Health
The core of the problem, according to Dr. Hyman and supported by extensive research, lies in the proliferation of ultra-processed foods. These foods, often high in sugar, salt, and unhealthy fats, are engineered for palatability rather than nutritional value. The Global Burden of Disease study, a comprehensive analysis of health trends in 195 countries, revealed that dietary factors are now the leading cause of mortality globally, surpassing even tobacco use. This underscores the significant impact of food choices on public health.
Dr. Hyman specifically points to the United States as a key driver of this global shift. “We in the United States have created the worst diet in the world and exported it to all countries,” he explains. He illustrates this point with the example of China, where diabetes rates were historically low. Before 1984, the prevalence of type 2 diabetes was approximately one in 150. However, with the introduction of prompt-food chains like McDonald’s and KFC, the rate has dramatically increased to one in ten. This demonstrates how environmental changes, specifically the availability of ultra-processed foods, can rapidly alter health outcomes.
The Exposome and Genetic Predisposition
While genetics play a role in health, Dr. Hyman emphasizes that genes are not destiny. He introduces the concept of the “exposome” – the totality of environmental exposures throughout a person’s life, including diet, activity level, stress, and toxins. “What determines the outcome of your health isn’t your genes, it’s what happens to your genes over your lifetime,” he explains. These exposures can activate or deactivate genes, influencing the development of chronic diseases or promoting overall health.
This understanding empowers individuals to capture control of their health by modifying their lifestyle and environment. It’s not simply about inheriting a predisposition to a disease; it’s about how those genes are expressed through daily choices. The idea that individuals have agency over their health is a powerful shift from the traditional medical model, which often focuses on managing symptoms rather than addressing root causes.
Reclaiming a Healthy Lifespan
A concerning trend highlighted by Dr. Hyman is the disproportionate amount of life spent in poor health. Approximately 20% of a person’s life is often lived with illness, meaning that healthy lifespan doesn’t necessarily equal overall lifespan. However, he argues that this doesn’t have to be the case. “You can have a healthy lifespan equal to your lifespan, which means you live a full life, enjoying your life until the finish.”
This requires a proactive approach to health, prioritizing preventative measures and lifestyle changes. Focusing on whole, unprocessed foods, regular physical activity, stress management, and adequate sleep are all crucial components of a healthy lifestyle. Addressing the underlying causes of disease, rather than simply treating symptoms, is key to maximizing both lifespan and healthspan.
The challenge, however, is navigating a food system that actively promotes unhealthy choices. Ultra-processed foods are often cheaper and more readily available than healthier alternatives, creating barriers to healthy eating, particularly for vulnerable populations. Addressing this systemic issue requires policy changes, increased access to nutritious food, and public health initiatives that promote healthy eating habits.

As research continues to illuminate the link between diet and health, the require for systemic change becomes increasingly apparent. The next step in addressing this global health crisis will likely involve increased scrutiny of food industry practices and the implementation of policies that prioritize public health over profit.
