Zusammenfassung
An acclaimed nutrition educator reveals how the foods you’re eating to get healthy might be making you sick.
 
“Sally Norton’s well-researched book makes a truly important contribution to the literature in revealing just how much oxalates can damage the human body.”—Nina Teicholz, author of The Big Fat Surprise
 
If you’re eating a healthy diet and you’re still dealing with fatigue, inflammation, anxiety, recurrent injuries, or chronic pain, the problem could be your spinach, almonds, sweet potatoes, and other trusted plant foods. And your key to vibrant health may be quitting these so-called superfoods.

After suffering for decades from chronic health problems, nutrition educator Sally K. Norton, MPH, discovered that the culprits were the chemical toxins called oxalates lurking within her “healthy,” organic plant-heavy diet. She shines light on how our modern diets are overloaded with oxalates and offers fresh solutions including:

• A complete, research-backed program to safely reverse your oxalate load
• Comprehensive charts and resources on foods to avoid and better alternatives
• Guidance to improve your energy, optimize mood and brain performance, and find true relief from chronic pain
 
In this groundbreaking guide, Norton reveals that the popular dictum to “eat more plants” can be misleading. Toxic Superfoods gives health-seekers a chance for improved energy, optimum brain performance, graceful aging, and true relief from chronic pain.

Health Food or Health Disaster?**

The greatest obstacle to discovering the shape of the earth, the continents, and the ocean was not ignorance but the illusion of knowledge.  —Daniel J. Boorstin, The Discoverers, 1985

Actor Liam Hemsworth publicly blamed spinach smoothies for a 2019 kidney stone episode that required surgery. At age 29 he had to miss a movie premiere and an awards banquet because of it. In 2020, Men’s Health magazine quoted Mr. Hemsworth as saying: “February last year, I was feeling really low and lethargic and wasn’t feeling good generally. And then I got a kidney stone.” He added: “Every morning I was having five handfuls of spinach and then almond milk, almond butter, and also some vegan protein in a smoothie. And that was what I considered super healthy. So, I had to completely rethink what I was putting into my body.”

This book invites you to do just that: Rethink your “health” food.

Even moderate, relatively common levels of oxalate in a habitual diet can fuel the customary aches and pains of life: digestive distress, inflamed joints, chronic skin issues, brain fog or mood problems, as well as health declines associated with “normal” aging. And then there are those painful kidney stones. Eighty percent of them are formed from oxalate, much of which comes from the foods we eat.

Mr. Hemsworth was one of the lucky ones. Three weeks after completing a 10-day “green smoothie cleanse” for weight loss, a New York City woman with a history of gastric bypass surgery went to the Nassau University Medical Center on Long Island, complaining of persistent nausea, weakness, and poor appetite. She was immediately put on a low-oxalate diet, but it was too late, her kidneys did not recover, and she remained dialysis-dependent.

Similar examples of kidney failure due to consumption of “health foods” include a man, also attempting to lose weight, who juiced celery, carrots, parsley, beets with their greens, and spinach. The man’s kidneys were seriously damaged. His doctors at the Mayo Clinic prescribed dialysis and a low-oxalate diet. He stopped juicing. It took more than four months for his kidney function to improve.

And it’s not just kidney failure. Damage from dietary oxalate can hit any—or every—bodily system and cause serious chronic health problems. It’s no accident that Mr. Hemsworth’s kidney stones were preceded by malaise, depression, and lethargy. However, most medical journals reporting health crises from overzealous oxalate consumption fail to mention the non-kidney problems that likely also occurred.

Because it is so easy to overeat oxalates, chances are you may already be experiencing occasional oxalate-related aches and pains somewhere in your body. Do you tend to get a stiff neck? In those of us with dietary oxalate overload, pain, knots, or stiffness in the top of the shoulders or in the upper or lower back are typical. Some people experience chronic or intermittent joint inflammation, gout, arthritis, carpal tunnel syndrome, or a more generalized stiffness, often accompanied by a lack of pep.

Or perhaps you have long-standing injuries or chronic itching, tingling, or pain that never fully resolves. Your doctors can’t help you figure out what is going on; they seem to think you’re “just fine” and should just live with life’s little miseries. If any of this rings true for you—if you don’t feel “just fine”—this book may be your golden opportunity to turn things around.

Other seemingly small things can be indicators of oxalate overload, including itchy or dry eyes, eye floaters, excessive tartar on the teeth, tooth sensitivity, sensitive or frail skin, and odd things like pressure or pain in the loins, irritable bladder, urinary tract infections, frequent urination, or cloudy urine. Liver stress from oxalate overload can aggravate chemical sensitivity. Digestive problems like indigestion, reflux, bloating, excessive belching, constipation, and irritable bowel syndrome are especially common. Additional symptoms can include shortness of breath, sinus problems, yeast infections, and even cold hands and feet.

Do you ever feel especially clumsy or occasionally have poor coordination? Do you get muscle spasms or eye twitches, or have memory or word-finding difficulties, headaches, or anxiety and panic disorder? Being neurotoxic, oxalates can get in—and on—your nerves. Oxalic acid chemically bonds to calcium and other minerals and interferes with cell energy production. Relentless oxalate consumption can cause oxalate to build up inside the body without obvious symptoms and may culminate years later as “old-age problems” such as bad bones, chronic pain, and vision and hearing loss. Oxalate deposits are also associated with brain cell damage that leads to Parkinson’s disease and dementia disorders.

You don’t have to have symptoms to have a disease, and oxalate toxicity is no exception. But a wide spectrum of potential symptoms can occur in the wake of oxalate overload, and each of us will (eventually) suffer from our own unique subset of them if we persist with high-oxalate eating. To make it easier to consider your own situation, you can take the Risks, Symptoms, and Exposure Self-Quiz (in the Resources section, page 275) or look over Table 10.1, which lists body systems and oxalate-associated symptoms. Keep reading to get the interesting details.

There are several factors that increase the likelihood that your high-oxalate diet may be leading to oxalate overload and symptoms, including:

•A diet low in calcium and other minerals (dairy-free and vegan diets are two examples)

•Frequent use of gut-irritating foods, including beans, bran, whole grains, quinoa

•A history of repeated use of antibiotic or antifungal medications

•Long-term use of non-steroidal anti-inflammatory pain medications (NSAIDs)
