A growing number of Americans are deviating from conventional diets, exploring what proponents call 'dark nutrition'—a philosophy centered on unprocessed foods, sometimes including items like raw dairy, beef tallow, and organ meats. This trend sees individuals questioning the benefits of common vegetables and embracing more extreme dietary changes in pursuit of improved health and longevity.

Axay Shah, a 67-year-old jewelry businessman, has followed a strictly plant-based raw food diet for 17 years. He attributes his freedom from chronic disease and his ability to train for marathons to this lifestyle. "My day is fruit, greens, nuts and seeds," Shah told the Daily Mail. "Simple, not starving." His guiding principle is, "If it is not made by Mother Nature, it is not going on my plate."

Another prominent figure in this movement is Vani Hari, known online as the Food Babe. Hari, 47, eliminated processed foods after experiencing significant health issues, including eczema, asthma, and severe allergies, during her childhood. "When I pulled back from that and decided to eat whole real food, everything changed," she told the Daily Mail. Hari, who grew up with parents who were "very trusting of the American food supply," discovered that much of her previous diet consisted of "just so many chemicals."

Hari became an advocate for this lifestyle, gaining national attention for campaigns urging food companies to remove artificial ingredients from their products. She is also associated with the Make America Healthy Again movement led by Robert F. Kennedy Jr.

Others adopt even more unconventional approaches. Kevin Corl, 61, and his wife Wendy reportedly reversed chronic pain and reduced their reliance on medication by shifting their diet to primarily consist of butter, heavy cream, and red meat. "I used to hit walls. I never hit walls anymore," Corl said.

Rob Richards, 34, described the 'dark nutrition' approach as "trying stuff aggressively, for better and worse." He acknowledged that while individuals might "really mess themselves up," they can also gain insights not found in mainstream advice. Richards and others are "willing to sacrifice a bit of their safety" in the pursuit of longevity, suggesting a high tolerance for risk in exchange for perceived health benefits.
