Regulatory Differences Between the US and Europe
One of the most significant reasons why US food is so unhealthy compared to other countries is the stark difference in regulatory approaches. While the European Union (EU) generally adheres to a “precautionary principle,” banning potentially problematic ingredients until they are proven safe, the US operates under a “risk-based system”. This means a substance can be considered 'Generally Recognized as Safe' (GRAS) and enter the market until a problem arises, a system that effectively lets companies self-police.
Additives and Hormones: A Tale of Two Standards
The discrepancy is most evident in the use of food additives and hormones. Many common additives in the US are banned in Europe, prompting American companies to produce different, cleaner versions of their products for the international market.
Common Additives Banned in Europe but Used in the US:
- Potassium bromate: A dough conditioner linked to cancer in animal studies, it is used in some US baked goods but banned in the EU.
- Azodicarbonamide (ADA): A dough conditioner and whitening agent associated with respiratory issues, banned in the EU.
- Titanium dioxide: A whitening agent used in candies and icings, banned in the EU since 2022 due to concerns about DNA damage.
- Brominated Vegetable Oil (BVO): An emulsifier used in some US citrus sodas, linked to potential thyroid and neurological issues, banned in the EU.
- rBGH (Recombinant Bovine Growth Hormone): An artificial hormone used to boost milk production in US cows, banned in Europe and Canada.
The Impact of Ultra-Processed Foods
The American diet is dominated by ultra-processed foods, which are typically high in sugar, salt, and unhealthy fats, and low in nutritional value. These products are designed to be convenient, affordable, and highly palatable, leading to overconsumption. The proliferation of these foods is supported by aggressive marketing and a food system that prioritizes cheap, shelf-stable ingredients over fresh, whole foods. A 2025 CDC report highlights that 55% of the average American's diet consists of ultra-processed foods, a number that jumps to 62% for children and teens.
The Role of Agricultural Practices and Subsidies
US agricultural practices also contribute to the quality gap. The US system often favors large-scale, industrial farming centered around subsidized commodity crops like corn and soy. These crops are then heavily processed into high-fructose corn syrup, vegetable oils, and feed for livestock, forming the backbone of the fast-food and processed-food industries. In contrast, many European countries have agricultural policies that place a greater emphasis on small, local farming and stricter regulations on livestock practices.
Comparison of US and EU Food System Characteristics
| Feature | United States (US) | European Union (EU) |
|---|---|---|
| Regulatory Principle | Risk-Based ('Generally Recognized as Safe') | Precautionary Principle |
| Food Additive Usage | Allows many additives banned in the EU | Bans potentially risky additives until proven safe |
| Use of Hormones | Allows rBGH and other growth hormones in livestock | Bans the use of artificial growth hormones |
| GMO Labeling | No mandatory labeling of Genetically Modified ingredients | Strict labeling and traceability requirements |
| Ultra-Processed Food % | High (over 50% of average diet) | Lower (e.g., ~14-43% in many countries) |
| Dominant Agricultural Model | Large-scale industrial farming of subsidized commodity crops | Greater emphasis on local farms, stricter environmental rules |
Economic Factors and Consumer Behavior
Economic pressures play a significant role in US food choices. For many families, ultra-processed foods are cheaper and more accessible than fresh produce or lean protein. Marketing campaigns, particularly those targeting children, further normalize these unhealthy eating habits. While European countries also have fast food, the widespread availability and lower cost of fresh, high-quality ingredients, combined with different cultural eating patterns, contribute to a healthier overall dietary landscape.
The Consequences for Public Health
The consequences of these systemic differences are visible in public health data. High consumption of ultra-processed foods, alongside ingredients like high-fructose corn syrup and artificial fats, has been linked to increased rates of obesity, type 2 diabetes, heart disease, and other chronic illnesses. While other factors like lifestyle and genetics play a role, the quality of the food supply is an undeniable contributor. The US regulatory system's slower response to emerging concerns about additives and chemicals puts its population at higher risk compared to countries with a more cautious approach.
Conclusion: A System in Need of Change
The answer to the question of why US food is so unhealthy compared to other countries is multi-faceted, involving regulatory failures, economic incentives, and ingrained dietary habits. While individual choices are part of the equation, the systemic differences—particularly the stark contrast in regulatory philosophy between the US and the EU—create an environment where processed, low-quality food is the norm rather than the exception. Addressing this complex issue requires a shift in both policy and consumer demand, prioritizing public health over industrial convenience.
