What is *Dark Calories* by Catherine Shanahan about?

*Dark Calories* exposes how industrial seed oils like soybean and canola oil contribute to chronic diseases by causing oxidative stress, inflammation, and cellular damage. Dr. Shanahan traces their rise in modern diets, critiques flawed nutrition science, and offers actionable steps to replace these oils with traditional fats. The book blends scientific research with historical analysis to challenge mainstream dietary guidelines.

Who should read *Dark Calories*?

This book is essential for anyone battling obesity, diabetes, or autoimmune conditions, as well as readers seeking to understand hidden dietary toxins. Nutritionists, healthcare professionals, and skeptics of low-fat diet dogma will find evidence-based critiques of vegetable oils and practical strategies for adopting ancestral dietary principles.

Is *Dark Calories* worth reading?

Yes—it combines rigorous science with real-world solutions, debunking myths about cholesterol and saturated fats. Shanahan’s analysis of industry influence on nutritional guidelines and her “Hateful Eight” oils list provides a framework for reclaiming metabolic health. The actionable meal plans and oil-avoidance tactics make it a valuable resource.

What are the “Hateful Eight” oils?

The “Hateful Eight” include soybean, canola, corn, cottonseed, sunflower, safflower, rice bran, and grapeseed oils. Shanahan argues these industrial seed oils disrupt cellular function, accelerate aging, and promote inflammation due to their unstable molecular structures and high polyunsaturated fat content. She links them to modern epidemics like heart disease and diabetes.

How does *Dark Calories* explain oxidative stress?

Vegetable oils contain fragile fatty acids that oxidize easily, generating free radicals that damage cell membranes, mitochondria, and DNA. This oxidative stress undermines energy production, weakens immunity, and contributes to chronic inflammation—a root cause of conditions like arthritis and Alzheimer’s.

What historical factors does Shanahan blame for vegetable oil dominance?

Shanahan critiques Ancel Keys’ flawed lipid-heart hypothesis and the vegetable oil industry’s lobbying efforts, which wrongly vilified saturated fats. Post-WWII marketing campaigns rebranded industrial seed oils as “heart-healthy” to capitalize on cheap byproducts of agriculture and chemical processing.

What are *Dark Calories*’ key dietary recommendations?

- Eliminate the “Hateful Eight” oils. - Use traditional fats like butter, olive oil, and coconut oil. - Prioritize nutrient-dense, unprocessed foods. - Avoid sugary snacks that exacerbate oil-related metabolic damage.

How does *Dark Calories* challenge cholesterol myths?

Shanahan argues LDL cholesterol isn’t inherently harmful—oxidation caused by seed oils is the real culprit. She cites studies showing populations with higher cholesterol levels often have lower heart disease rates, opposing the low-fat diet paradigm.

The Toxic Truth in Your Pantry

Have you ever wondered why certain foods leave you feeling sluggish, bloated, or craving more? The answer might be hiding in plain sight on your kitchen shelves. In her groundbreaking book "Dark Calories," Dr. Catherine Shanahan reveals a shocking truth: approximately 30% of the calories in our modern diet come from an invisible substance most people don't even notice-vegetable oils. These industrial seed oils appear in over 80% of packaged foods yet receive almost no attention in medical education. When the Los Angeles Lakers hired Dr. Shanahan to create their PRO Nutrition program, eliminating vegetable oils from athletes' diets produced remarkable results, a practice that soon spread to other NBA teams including championship winners like the Golden State Warriors and Toronto Raptors. Dr. Drew Pinsky, after trying her approach, remarked: "If you had told me that two weeks into it, I would feel this good, I wouldn't have believed you." This isn't just another diet book-it's a comprehensive expose of how these seemingly innocent oils are systematically destroying our health, and more importantly, how we can reclaim it.

Chapitre 2

The Deceptive Nature of Vegetable Oils

Despite their healthy-sounding name, vegetable oils don't come from vegetables at all. They're extracted from seeds-corn, canola, cottonseed, soybean, sunflower, safflower, grapeseed, and rice bran oils-what Dr. Shanahan calls "the Hateful Eight." Unlike traditional animal fats humans have consumed since the Stone Age or oils from fatty fruits like olives and coconuts used for thousands of years, vegetable oils are industrial products barely 150 years old. Their history begins in soap factories. When cottonseed oil was no longer needed as lamp fuel due to petroleum's rise, it was secretly and illegally added to animal fats and olive oil. By 1907, Procter & Gamble developed hydrogenation to solidify cottonseed oil into what became Crisco, marketing this flavorless product as "clean" and "healthier" than animal fats. Though Americans initially rejected liquid vegetable oils, post-WWII changes in animal feeding practices dramatically increased soy production, as defatted soy meal became popular animal feed. The resulting soy oil, initially used for plastics, became food by the 1950s. The production process is far from natural. Vegetable oil manufacturing occurs in massive factories resembling oil refineries. Seeds are heated to 400-600F, crushed through expeller presses, and the remaining "cake" is washed with hexane (a gasoline component) to extract remaining oil. This crude oil contains gums, free fatty acids, oxidative components, toxic aldehydes, peroxides, metals, and waxes, requiring extensive processing to become "edible." The refining process involves numerous steps-degumming, dewaxing, deodorizing-each requiring specialized equipment and chemical expertise. What makes these oils so harmful is their chemical instability. All dietary fats consist of fatty acids-saturated, monounsaturated, and polyunsaturated-linked by glycerol molecules. Vegetable oils contain high levels of polyunsaturated fats (PUFAs), which are highly susceptible to oxidation due to their multiple double bonds. Unlike stable saturated fats in butter or coconut oil, these double bonds readily react with oxygen, creating entirely new toxic compounds. Just one oxidized PUFA molecule can trigger a chain reaction affecting billions of molecules per second, creating numerous lipid oxidation products (LOPs). Only antioxidants or saturated fats can halt these toxic cascades.

How Oxidative Stress Fuels Disease

Disease begins at the cellular level. Despite medical education acknowledging "cellular pathology," modern medicine fails to apply this concept to actually heal patients. The toxins in seed oils promote cellular oxidative stress, which depletes antioxidants and eventually leads to inflammatory and degenerative diseases. In 1949, Denham Harman, a Shell Oil Company chemist obsessed with understanding why we die, developed his groundbreaking "free radical theory of aging." Free radicals-destructive molecules formed during oxidation reactions-damage cellular infrastructure similarly to radiation. Harman proposed these molecules gradually destroy our cells until tissues and organs fail, leading to disease or death. Initially ridiculed, his theory eventually launched the field of free radical biology, linking free radicals to cancer, cardiovascular disease, strokes, Alzheimer's, and over a hundred other conditions. While we need some polyunsaturated fatty acids for essential functions, they're vulnerable to oxidation damage. Our cell membranes contain 30-40% PUFA, which must be protected by antioxidants, primarily vitamin E. Like a sacrificial domino that diverts energy, vitamin E nestles among PUFA molecules in cell membranes, trapping free radicals and becoming oxidized itself to protect neighboring PUFAs. However, vitamin E can't work alone-it's part of an antioxidant team that plays molecular "hot potato" with free radicals, passing them from vitamin E to vitamin C to glutathione to NADPH, reducing the radical's energy until it's neutralized. The 1950s-60s Elgin Project revealed the dangerous relationship between PUFA consumption and vitamin E requirements. Participants eating corn oil (30% PUFA) needed three times more vitamin E than those eating lard (4% PUFA). More alarming, after two years on high-PUFA diets, participants' vitamin E levels plummeted despite consistent supplementation, and their cells showed oxidative damage. This occurred because their body fat had become saturated with PUFA. Neuroscientist Stephan Guyenet confirmed this pattern in a 2015 literature review analyzing 46 studies spanning 1959-2008, which showed human body fat PUFA content had increased from 9.1% to 21.5%-perfectly tracking Americans' doubled vegetable oil consumption. When we experience oxidative stress too frequently due to high-PUFA body fat, we develop chronic inflammation. Unlike acute inflammation, which helps heal injuries and fight infections, chronic inflammation makes us chronically unwell and can confuse the immune system, causing autoimmune diseases. Most chronic diseases today are inflammatory conditions-from heart disease and diabetes to chronic pain syndromes and long COVID.

Chapitre 4

How Vegetable Oils Drive Obesity and Metabolic Disease

The World Health Organization describes obesity as humanity's largest health threat, yet medical experts can't agree on its cause. At a prestigious 2022 gathering at London's Royal Society of Medicine, experts blamed everything from genetics to inactivity, chaotic family schedules, screen time, pesticides, sugar, and the microbiome-with the host lamenting the complete lack of consensus. Remarkably, not one speaker mentioned that roughly a third of our calories now come from vegetable oil. The correlation between vegetable oil intake and obesity is striking, while correlations with other dietary variables-even total calories-are notably absent. Yet doctors, nutritionists, and obesity researchers remain completely unaware of vegetable oil's negative health effects. The process begins with inflammatory body fat. Research by Dr. Chris Knobbe reveals that ancestral diets contained only 1.5-3% PUFA in body fat, while modern Americans have 21.5% or more-a 400% increase. This dramatic shift affects everyone regardless of weight, creating inflammatory fat with a lower melting point (making it flabbier) and reduced ability to produce satiety signals like leptin. Even thin people often have unhealthy visceral fat around organs (TOFI-thin outside, fat inside), with studies showing 45% of women and 60% of men who appear thin actually have excessive internal fat. When our body fat is inflammatory and high in PUFA, we lose our natural ability to efficiently burn fat between meals. Fat burning occurs in mitochondria-tiny cellular power stations that generate energy through a remarkable process involving protein "turbines" that spin to create ATP (adenosine triphosphate). Italian scientists discovered that PUFAs dramatically reduce mitochondrial energy production compared to saturated and monounsaturated fats. When mitochondria burn PUFA, their power output drops within minutes, and they begin generating harmful free radicals that cause oxidative stress. When cells can't efficiently burn PUFA-laden body fat, they desperately turn to blood sugar for fuel. Medical science now recognizes that many overweight people barely burn body fat at all-not while resting, fasting, or even during light exercise. With a mere teaspoon of glucose in our entire bloodstream, this increased demand quickly depletes available sugar, causing hypoglycemia. Human studies confirm that high-PUFA diets increase glucose burning and suppress fat burning. As cells continue demanding more sugar, the body adapts by raising blood glucose levels between meals and during overnight fasts. The liver responds to tissue distress signals by releasing more glucose into the bloodstream. While this mechanism is designed for temporary needs during intense activity, it becomes chronic when cells can't efficiently burn body fat. Blood glucose levels frequently exceed normal values, causing sugar to stick to cell membranes, joint tissues, and other structures, resulting in widespread damage throughout the body.

The Hidden Hunger Crisis Driving Modern Behavior

Our relationship with hunger has fundamentally changed. When asked how they feel when hungry, people now describe going "rampant," becoming "hangry," or getting "cranky and agitated." Many fear hunger, especially when driving or away from food. This isn't normal hunger-it's a symptom of our widespread insulin resistance. Normal hunger is about nutrition, primarily triggered by the hormone ghrelin, which is tied to circadian rhythms. It creates a gentle reminder to eat, accompanied by mild stomach grumbling. If ignored, it subsides after a few minutes, especially with distraction. True normal hunger can even be energizing, as ghrelin helps burn fat. The new, unhealthy hunger originates in the brain rather than the stomach, and persists until fed. The brain, which constitutes just 2% of body weight but uses 20% of our calories and 25% of blood sugar, is uniquely sugar-dependent. Protected by the blood-brain barrier, it can't directly access larger molecules like fat, making it reliant on sugar and ketones. In insulin resistance, cells struggle to use body fat for energy and the liver can't efficiently produce ketones. When blood sugar drops, specialized glucose-sensing cells in the brain trigger hunger signals. For insulin-resistant individuals, this can feel like an emergency because cells have only about twenty seconds of energy reserves. Most critically, insulin resistance makes you feel hypoglycemic even when blood sugar is normal, as your body has adjusted to require higher baseline levels. The two primary low brain energy symptoms are brain fog (trouble concentrating) and fatigue. When hunger (plan A) doesn't resolve hypoglycemia, the brain activates plan B: releasing stress hormones like adrenaline and cortisol from the adrenal glands via the vagus nerve. These hormones tell the liver to raise blood sugar, solving the brain's energy crisis, but causing numerous unpleasant side effects like shaking, anxiety, nausea, sweats, irritability, weakness, dizziness, headache, or heart palpitations. When our bodies need to make sugar, they rely primarily on protein through gluconeogenesis rather than fat, which can't efficiently convert to glucose. Unlike fat, protein isn't stored in large quantities in the body. When blood sugar drops and stress hormones rise, the body often breaks down muscle tissue to release proteins for conversion to sugar. This chronic muscle breakdown explains why insulin resistance makes building and maintaining muscle difficult. Dr. Francesco Leri's landmark 2018 study demonstrated that small but rapid drops in glucose levels can have lasting negative effects on emotional states. His experiment with mice showed that hypoglycemia created behaviors mimicking human anxiety disorders and depressed moods. Research increasingly suggests metabolic issues may be causative in mental illness, not just correlative. Dr. Roy Baumeister discovered that self-control is the character trait that best predicts success in school, work, and social life. His ego depletion theory demonstrated that willpower requires brain energy and depletes with repeated use. His research revealed that when experiencing low blood sugar, people rapidly lose willpower and impulse control. This affects everything from food choices to shopping, sexual behavior, drug use, gambling, and aggression.

Chapitre 6

The Great Cholesterol Deception

Contrary to popular belief, cholesterol isn't a toxin or waste product but an essential nutrient required by every cell. It appears as a waxy substance that helps maintain cell membrane flexibility. Most blood cholesterol is produced by the liver and intestinal cells to manufacture lipoproteins that deliver fats and fat-soluble vitamins throughout the body. Cholesterol serves as the body's equivalent of duct tape-a versatile building block that enables cell division, facilitates cellular communication, forms vitamin D, waterproofs skin, helps brain cells conduct electricity, and serves as the precursor to numerous steroid hormones including testosterone and estrogen. The cholesterol-heart attack connection is far weaker than commonly believed. A massive study of 136,905 heart attack patients revealed that only 25% had high LDL cholesterol levels when hospitalized, while 35% reported having been previously diagnosed with high cholesterol. This means normal or low cholesterol was actually a better predictor of heart attacks than high cholesterol. Rather than questioning this contradiction, the medical establishment doubled down, recommending even lower cholesterol targets. Multiple studies reveal the dangers of low cholesterol levels. Clinical trials show statin users develop 20-25% more cancers than those on placebo, with research linking low cholesterol to cancers of the colon, lung, and prostate. A 2007 BMJ article found "disturbing, highly significant" cancer risk in people with the lowest LDL levels. Even more surprisingly, a 2011 Japanese study found that low cholesterol is associated with mortality from stroke, heart disease, and cancer-the very conditions cholesterol-lowering is supposed to prevent. When biochemist Dr. Glen Lawrence published research showing that PUFAs lower cholesterol by disrupting fat distribution and creating inflammatory arterial deposits, he faced fierce criticism. Rather than addressing his scientific points, critics claimed he was using the "wrong kind" of evidence-animal and laboratory studies rather than meta-analyses of clinical trials. This hierarchy of evidence misleadingly places meta-analyses at the top while dismissing foundational scientific research. The cholesterol theory itself rests on the questionable work of Ancel Keys, whose methods have been considered substandard since the beginning-though most doctors remain unaware of these historical problems.

The Dark History of Nutrition Science

In the post-World War II era, as a new heart attack epidemic emerged, Ancel Keys became the controversial figure who would shape nutrition science for decades to come. Keys's 1953 paper "Atherosclerosis: A Problem in Newer Public Health" boldly declared dietary fat consumption drives heart disease by elevating blood cholesterol. This claim came at a time when men were dying of heart attacks in their forties and fifties, creating nationwide fear. However, his methods were fundamentally flawed. Of sixteen tables and figures, only one showed any correlation between diet and heart disease-a simple graph plotting fat consumption against heart attack rates in six countries. The graph suggested a perfect correlation, but Keys had deliberately omitted sixteen other countries that didn't fit his narrative. When other researchers published the complete twenty-two country data in 1957, the correlation disappeared. In January 1961, Time magazine named Ancel Keys Man of the Year, cementing his authority in the public consciousness. The magazine portrayed Keys as decisive compared to other researchers "bogged down with details" and claimed he had "the sheer weight of solid statistics" supporting his theory. The article quoted a Philadelphia physician saying Keys would shut down critics by claiming "I've got 5,000 cases. How many do you have?" This was a gross exaggeration. By 1961, Keys had actually evaluated the diet and cholesterol levels of just 180 heart attack cases-72 from the Twin Cities and 108 from Naples, Italy. Even by the Seven Countries Study's final analysis in 1985, the total case count reached only 2,289, far short of his claimed 5,000. Keys didn't work alone but aligned with influential physicians, including Dr. Paul Dudley White (AHA founder and President Eisenhower's physician) and Dr. Irvine Heinly Page (AHA president and Cleveland Clinic research chair). With Harvard Medical's endorsement and the AHA's platform, Keys's ideas gained widespread acceptance. In 1956, Keys helped launch the AHA's "Prudent Diet" television campaign, replacing butter, lard, beef, and eggs with vegetable oil, margarine, chicken, and cold cereal. Despite claiming to be evidence-based, the AHA promoted this diet before the Seven Countries Study had published any results. The organization had received funding from the vegetable oil industry, creating an undisclosed conflict of interest. Keys likely recognized that smoking posed a threat to his cholesterol theory because it operated through a completely different mechanism: oxidation. Since the 1920s, scientists had known that only oxidized cholesterol-not unoxidized cholesterol-created arterial plaques. This presented a fatal flaw in Keys's theory, as saturated fat is nearly oxidation-proof while polyunsaturated fatty acids (PUFAs) are extremely prone to oxidation and can oxidize nearby cholesterol.

Reclaiming Our Health: The Path Forward

Dr. Thomas Seyfried's groundbreaking research has revived Otto Warburg's 1920s hypothesis that cancer is fundamentally a metabolic disease, not genetic. Warburg discovered cancer cells have severely abnormal mitochondria that force them to generate energy by fermenting sugar rather than normal respiration. Seyfried's experiments conclusively demonstrate that mitochondrial dysfunction causes cancer and DNA mutations, not vice versa. His research shows that a ketogenic diet effectively starves cancer cells by reducing blood sugar while providing ketones that healthy cells can use but cancer cells cannot. Mental illness is increasingly being recognized as rooted in mitochondrial dysfunction and metabolic disease, not just genetic or random factors. Dr. Christopher Palmer from Harvard Medical School believes most mental disorders are actually mitochondrial metabolic disorders that disrupt the brain's energy access. Studies show ketogenic diets can dramatically improve mental health conditions-Dr. Georgia Ede reports that 50% of her patients benefit enough to reduce or eliminate medications. Despite nearly everyone in the United States being insulin resistant and on the path to diabetes, the American Diabetes Association continues recommending a diet emphasizing low-fat meats, fruits, and "whole grain" starchy foods-ironically, foods that raise blood sugar in diabetic patients. However, research shows that diets reducing oxidative stress can effectively reverse diabetes. The common factor in successful approaches is significantly reduced PUFA intake compared to the standard American diet. The conflicting research on low-carb diets for diabetes can be explained by examining PUFA content. In successful studies, participants consumed much less PUFA, while in unsuccessful ones, they got most of their fat from vegetable oils rather than traditional keto foods. This fundamental difference in PUFA content explains the dramatically different outcomes in diabetes reversal studies, highlighting that simply cutting carbs isn't enough-reducing vegetable oils is the critical overlooked factor for success.

Practical Steps to Eliminate Vegetable Oils

Eliminating vegetable oils from your diet begins with understanding healthier alternatives. The "Delightful Dozen" cooking fats include butter (especially grass-fed), extra virgin olive oil, unrefined peanut oil, coconut oil, avocado oil, ghee, sesame oil, palm oil, bacon fat, tallow, lard, and chicken fat. For each, there are specific culinary uses and nutritional benefits. To eliminate seed oils from your diet, you must read the ingredients list on every packaged product-even those you wouldn't expect to contain oils, like dried fruits, peanut butter, microwave popcorn, granola, canned tuna, olives, and even spice blends. Ingredients are listed in descending order by weight, with the first ingredient present in the largest amount. When vegetable oils are the only fat source, you can calculate the percentage of calories from oil using the nutrition facts. Even health-conscious people who cook with olive oil at home are likely consuming harmful vegetable oils when dining out. Restaurants use these oils because they're cheaper than traditional fats, regardless of price point-from fast food to fine dining establishments. Deep-fried foods are particularly problematic as the oils are continuously heated and reused for days, sometimes weeks. When dining out, avoid anything deep-fried, choose baked or steamed options, and be cautious with sauces and dressings, which typically contain seed oils. Choose solid protein sources like burgers, grilled (non-breaded) chicken, fish fillets, or slices of roasted meats. Soups generally contain minimal oil, with cream-based soups, miso, pho, and bone broth being particularly good choices.

Chapitre 10

Embracing Real Food for Optimal Health

The ancestral approach respects the culinary wisdom that enabled humanity to thrive globally. Unlike modern diets that focus on what not to eat, this approach draws from our healthiest ancestors who enjoyed greater health spans than we do today-living independent, active lives into their eighties. This approach identifies four pillars of human diet: eating fresh uncooked food, including meat (especially slow-cooked collagenous tissues), consuming fermented and sprouted foods, and eating nose-to-tail to utilize all animal parts. For optimal macronutrient ranges, Dr. Shanahan recommends 50-80% of calories from fat, 15-25% from protein (60-150g), and carbohydrates varying based on insulin resistance-15-20% (50-100g) for those with moderate insulin resistance and 0-40% (0-150g) for those with mild or no insulin resistance. Years of cholesterol-lowering seed oil consumption has suppressed many people's total body cholesterol, negatively impacting sex hormones, cortisol, and DHEA production. Consuming cholesterol-rich foods can rejuvenate hormone levels and accelerate metabolic recovery-men in their fifties and sixties have tripled testosterone levels, while women have normalized menstrual cycles and reduced menopausal symptoms. Protein is essential for more than muscle building-it's needed for every cell, organ, and for mitochondrial antioxidant enzymes. Yet protein deficiency is widespread and underdiagnosed: a third of adults over fifty and half of diabetics are significantly protein deficient. Most people need 60-100 grams daily minimum, far more than government recommendations suggest. Carbohydrates play a crucial role in metabolic recovery, especially for those with insulin resistance. The key is finding the right balance with slow-digesting carbs that provide steady energy without triggering insulin surges. These include sprouted-grain breads, yellow corn tortillas made with corn masa, beans, whole grains, nuts, and semi-starchy vegetables like peas, pumpkin, and winter squashes. Beyond fats, proteins, and carbs, salt, herbs, and spices are powerful allies for health and flavor. Salt is actually an antioxidant that helps prevent oxidation in foods and our bloodstream. Despite its bad reputation, salt is essential and our bodies regulate blood sodium effectively-chronic salt deprivation causes far more hospitalizations than excess salt consumption.

The Two-Week Challenge: Your Path to Transformation

The Two-Week Challenge aims to prove that you can divorce yourself from processed foods while experiencing the benefits of eliminating toxic oils. Within this short period, you'll likely notice increased energy, reduced inflammation, and decreased belly bloating. Those who test blood sugar will see improvements as insulin resistance begins to reverse. To prevent pathologic hunger, choose foods that digest slowly to maintain steady energy levels and prevent blood sugar fluctuations: 1) Include energizing fats (100-400 calories) at every meal; 2) Eat slow-digesting carbs at least twice daily, limiting sweets to after dinner; 3) Consume real-food protein rather than processed protein products; and 4) Avoid snacking completely to assess if meals are properly constructed. For breakfast, simple options include eggs prepared any way, avocado toast with "everything bagel" seasoning, cinnamon butter toast with nut butter and dried fruit, whole-milk yogurt with fruit and nuts, or full-fat cottage cheese with similar toppings. For lunch, consider a deli sandwich made with healthy bread and plenty of nitrite-free meats and cheeses, peanut butter and jelly on sprouted grain bread, celery boats filled with nut butter, pita stuffed with olive-oil-based hummus and vegetables, or flat tacos with melted cheese and salsa. Dinner options focus on simplicity, requiring minimal skill, equipment, and preparation time. Protein options include store-bought rotisserie chicken (checked for seed oils), shrimp cocktail, tuna melts made with olive oil-packed tuna, steak with simple Worcestershire marinade, fatty ground beef or lamb burgers (70-80% lean), and fish fillets cooked in butter, olive oil, or coconut oil. For those moments when you need something sweet, consider air-popped popcorn drizzled with butter, coconut macaroons with low sugar content, ice cream with the shortest possible ingredients list, or homemade crepes served with cream or fruit. If something in this book has resonated with you and you're ready to eliminate seed oils from your diet, know you're not alone. A growing community of health professionals, athletes, educators, and everyday people are awakening to this truth. Simply making a conscious effort to remove these oils from your life will improve how you feel. Our bodies crave connection to the natural world, most powerfully established through eating flavorful, fresh ingredients from healthy soil. The hardest part is making the decision to change; once truly committed, you'll naturally find ways to succeed.
