The Feingold Diet: Origins, Principles, and Legacy

The Feingold Diet, developed in the 1970s by pediatric allergist Dr. Benjamin Feingold, is one of the earliest dietary approaches aimed at addressing behavioral and learning problems in children. Most famously, it was proposed as a nutritional intervention for hyperactivity and what would later be categorized as Attention Deficit Hyperactivity Disorder (ADHD). Although controversial in mainstream medicine, the Feingold Diet has persisted in alternative health and parental advocacy circles for decades, illustrating the strong connection people see between diet, behavior, and overall well-being.

Origins and Development

Dr. Benjamin Feingold (1899–1982), a physician trained in pediatrics and allergy, began noticing in the early 1970s that some of his young patients with learning and behavioral difficulties improved markedly when certain artificial additives were removed from their diets. In particular, he identified synthetic food dyes, artificial flavorings, preservatives such as BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene), and later the petroleum-derived sweetener aspartame as potential culprits. Feingold published his findings in the 1974 book Why Your Child Is Hyperactive, which quickly became a bestseller and attracted nationwide attention from parents desperate for alternatives to stimulant medications like Ritalin.

The Feingold Diet soon evolved into a structured elimination program. It began by cutting out all artificial colors, artificial flavors, specific preservatives, and later certain naturally occurring salicylates (compounds present in foods like apples, grapes, and tomatoes). After a period of strict elimination, foods were reintroduced systematically to determine which triggered symptoms. Parents reported improvements not only in hyperactivity but also in asthma, allergies, headaches, and sleep disturbances.

Principles of the Diet

At its core, the Feingold Diet is built around the belief that sensitive children (and adults) react adversely to certain food chemicals—especially artificial additives and high-salicylate foods. The plan emphasizes:

• Elimination of synthetic food dyes (such as Yellow No. 5, Red No. 40, Blue No. 1), which were—and still are—prevalent in candies, cereals, beverages, and processed foods.
• Avoidance of artificial flavorings and preservatives, particularly BHA, BHT, and TBHQ.
• Limiting salicylate-rich foods, since these natural compounds can mimic the effects of aspirin and may trigger behavioral or physical symptoms in sensitive individuals.
• A whole-foods approach, promoting fresh fruits and vegetables (low in salicylates), unprocessed meats, whole grains, and natural alternatives.

The Feingold Association of the United States (FAUS), founded in 1976, provided lists of acceptable foods and consumer guides, helping families navigate grocery stores and restaurants.

Controversy and Criticism

From its inception, the Feingold Diet has been both celebrated and criticized. Many parents passionately claimed it transformed their children’s lives, reducing disruptive behavior and improving focus. However, large clinical trials conducted in the late 1970s and early 1980s produced mixed results. Critics argued that parental expectations (placebo effects) might account for improvements, while supporters countered that the studies were too short or failed to screen for children who were especially sensitive.

By the 2000s, mainstream medical opinion still did not endorse the Feingold Diet as a universal treatment for ADHD. Nevertheless, research into food additives continued. Several studies in Europe and the United States found links between artificial colors and hyperactivity, especially in sensitive children. In 2007, a major British study (the “Southampton Study”) concluded that artificial food dyes increased hyperactive behavior in the general population of children. This prompted the European Union to require warning labels on foods containing certain synthetic dyes, though no such requirement exists in the United States.

Broader Impact and Legacy

Whether or not the Feingold Diet is universally effective, its impact on public health debates has been significant. It was one of the first widely publicized attempts to connect children’s behavior with environmental and dietary exposures. The diet fueled the natural foods movement of the 1970s and 1980s, aligning with growing concerns about processed foods, pesticides, and chemical additives. For many parents, it offered not just a treatment plan but also a philosophy of reducing unnecessary synthetic substances in daily life.

The Feingold Diet also prefigured later interest in elimination diets, such as gluten-free or casein-free protocols for autism, and the broader “clean eating” trend. Even families who do not strictly follow Feingold’s recommendations have embraced the idea that diet can influence mood, behavior, and cognitive performance.

Conclusion

The Feingold Diet remains a pioneering example of dietary intervention for behavioral and developmental concerns. While scientific consensus does not fully endorse its claims, many families continue to find value in avoiding artificial additives and emphasizing whole, natural foods. Its enduring legacy lies in raising awareness of how modern food processing affects children, and in empowering parents to look critically at what goes into the foods they feed their families. In many ways, the Feingold Diet helped lay the groundwork for today’s broader cultural interest in food quality, environmental toxins, and holistic approaches to health.
