Dark nutrition: What happens when people stop trusting food and nutrition science?

Dark nutrition is a term describing a style of thinking about food and health, not a specific diet. Followers of this approach question mainstream nutritional advice and often turn to unconventional eating practices. This can involve avoiding certain foods like seed oils, unpasteurized milk, and vegetables, while also consuming high doses of supplements or even raw roadkill.

These choices typically stem from concerns about pesticides, toxins, and pollutants in food, or when individuals seek answers to health issues that doctors cannot resolve. They self-experiment with their diet in pursuit of better health or to treat a condition, regardless of whether scientific evidence supports their choices.

The issue with dark nutrition arises from the misleading information often encountered in the news, social media, and from family and friends. Journalists, influencers, and even health professionals may lack the expertise to accurately interpret complex research papers, leading to confusion. Even the government can sometimes get nutrition messages wrong.

The egg is a prime example of this, where its reputation changed dramatically over the years. Initially, the British Egg Marketing Board promoted eggs in the 1950s, but by 1968, the American Heart Association warned against excessive egg consumption, based on animal experiments linking cholesterol to heart disease. However, by the 1990s, eggs regained their status as a healthy, affordable protein source. Various other foods have also experienced swings in reputation over time.

Nutrition science, though not as old as other scientific disciplines, has only recently uncovered much of its knowledge. Consequently, there are many unanswered questions, and findings can change as researchers search for answers. Nutrition research often relies on self-reported dietary habits and health outcomes, which can lead to broad, conflicting, and confusing evidence.

This uncertainty contributes to the allure of dark nutrition, where individuals can feel in control of their diet despite a lack of solid scientific backing.

The post-truth era, characterized by the prioritization of beliefs and opinions over scientific evidence, further complicates the issue. Influencer culture plays a significant role in this, as people can share their thoughts as facts without evidence, further fueling dark nutrition. Despite these challenges, government guidelines remain a cornerstone of a healthy diet, evolving with new evidence.

However, alternative diets should always be evaluated based on the strength of the evidence, and dietary choices should be made with a critical eye towards the quality of available research.
