Exploring the tension between synthetic chemicals in our food supply and the healing power of nutritional medicine.
What if the very food and medicines we trust to keep us healthy are secretly making us sick? This is the provocative question at the heart of Randall Fitzgerald's 2006 book, "The Hundred-Year Lie: How Food and Medicine Are Destroying Your Health." 1 9
Fitzgerald argues that over the past century, our food and medicine have been systematically contaminated with synthetic chemicals, and this chemical onslaught is making us increasingly ill.
The book traces how thousands of novel chemicals have been introduced into our environment since the mid-19th century, creating a recent chemical assault that humans cannot possibly adapt to.
"Humans evolved over hundreds of thousands of years and cannot possibly adapt to this recent chemical assault." 1
Fitzgerald's investigation begins with a historical perspective, noting that the "lie" started with the rise of organic chemistry in the mid-to-late 19th century, particularly in Giessen, Germany, with chemist Justus von Liebig and his scientific descendants 1 .
The central argument of "The Hundred-Year Lie" is that we are experiencing a form of global mass poisoning through the cumulative effect of thousands of untested synthetic chemicals that have been approved by governments and are now ubiquitous in our environment 1 .

While Fitzgerald focuses on how modern food systems may be harming us, a growing body of scientific evidence reveals a more nuanced story: certain dietary approaches can have remarkable therapeutic and protective qualities 5 .
Research shows that what we eat significantly affects our disease risk. While some foods may contribute to chronic health conditions, others offer strong medicinal benefits 5 .
Evidence suggests that nutritional interventions can play a powerful role in health and healing.
Found in vegetables, fruits, beans, and grains, antioxidants protect cells from damage that might otherwise lead to disease 5 .
High-fiber foods promote healthy digestion and feed beneficial gut bacteria. Low-fiber diets are associated with higher risks of diseases including diabetes, heart disease, and colon cancer 5 .
Omega-3 fatty acids from foods like fatty fish help regulate inflammation, while amino acids from protein are essential building blocks for every tissue in our bodies 5 .
The idea that food can serve as medicine isn't new. One of the most famous experiments in medical history demonstrates this principle perfectly—James Lind's 1747 study on scurvy aboard the HMS Salisbury 6 .
Lind selected twelve sailors with scurvy, all displaying similar symptoms: "putrid gums, the spots and lassitude, with weakness of their knees" 6 . He then divided them into six pairs, giving each pair a different daily supplement.
Lind carefully controlled the experiment by ensuring all subjects had similar symptoms, "lay together in one place," and "had one diet common to all" 6 . This approach made his trial remarkably modern for its time.
Lind's experiment was groundbreaking for several reasons. It was one of the first documented examples of a controlled clinical trial in which conditions were carefully managed to isolate the effect of a single variable 6 .
Despite his results, the British Navy wouldn't officially adopt citrus rations for another forty years, highlighting how slow medical progress can be even with compelling evidence.
The outcome was dramatic and clear. After just one week, the two sailors who received oranges and lemons had recovered so completely that they were well enough to nurse the others 6 . None of the other treatments had produced meaningful improvements.
| Treatment Group | Number of Patients | Improvement After One Week |
|---|---|---|
| Oranges and lemons | 2 | Significant recovery, able to work |
| Cider | 2 | Minimal improvement |
| Elixir of vitriol | 2 | Minimal improvement |
| Vinegar | 2 | Minimal improvement |
| Sea-water | 2 | Minimal improvement |
| Garlic and barley paste | 2 | Minimal improvement |
| Experimental Element | Lind's Approach | Why It Was Advanced for Its Time |
|---|---|---|
| Patient Selection | Chose patients with similar symptoms | Reduced confounding variables |
| Control of Environment | Housed all patients together | Eliminated environmental differences |
| Standardized Diet | Same base diet for all groups | Isolated the effect of treatments |
| Multiple Comparison Groups | Six different interventions | Allowed direct comparison of approaches |
| Clear Documentation | Detailed records of methods and outcomes | Enabled verification and replication |
Contemporary research has expanded on Lind's early work, identifying specific food components with medicinal properties and developing sophisticated approaches to using nutrition therapeutically.
| Food Component | Primary Medicinal Functions | Research Findings |
|---|---|---|
| Berries | Disease prevention through antioxidants | Diets rich in berries may protect against chronic conditions, including certain cancers 5 . |
| Cruciferous Vegetables | Heart disease prevention, longevity promotion | High intake of raw vegetables may decrease heart disease risk and promote longevity 5 . |
| Fatty Fish | Inflammation reduction, heart protection | Omega-3 fatty acids fight inflammation and protect against heart disease 5 . |
| Medicinal Mushrooms | Immune system support | Maitake and reishi mushrooms contain compounds shown to boost immune function 5 . |
| Turmeric & Ginger | Anti-inflammatory, arthritis symptom relief | Research suggests these spices may help ease arthritis symptoms 5 . |
| Green Tea | Reduced inflammation, lower disease risk | Extensive research links green tea to multiple health benefits 5 . |
The field of culinary medicine has emerged as a formal discipline that integrates evidence-based medicine and nutrition to create dietary recommendations for preventing and treating medical conditions 2 .
Instead of a one-size-fits-all approach, culinary medicine adapts to individual patients' food preferences and disease states to improve health outcomes 2 .
Providing medically-tailored meals to patients with chronic conditions significantly increases dietary adherence above 90% (compared to less than 50% with standard dietary advice) and leads to dramatically better health outcomes 2 .
Fitzgerald appears correct in highlighting the potential dangers of our chemically-saturated environment. The massive expansion of synthetic chemicals since World War II has undoubtedly changed our relationship with both food and medicine 1 .
The story is more complex than simple condemnation of modern food systems. While some aspects may be contributing to disease, the strategic use of specific foods and dietary patterns represents a powerful tool for prevention, treatment, and healing.
The true lesson may be that we need greater transparency about what's in our food and medicine, coupled with increased recognition of food's medicinal potential.
The most balanced approach may be to acknowledge both perspectives: working to reduce our exposure to harmful synthetic chemicals while simultaneously embracing the medicinal power of whole, nutritious foods.
