What’s a Dangerous Oxalate Level?

Don't risk a dangerous oxalate level

Easy to Over-Do It, Easy to Fix It

Your go-to foods could pave the way for a dangerous oxalate level in your body and lead to very real health problems. Consider these common examples of popular foods that make it way too easy to overdo oxalate:

Are you into peanut butter, chia seeds, seeded wheat bread, sesame crackers, or nuts? If so, you could be eating a dangerous level of oxalate.

Do you reach for spinach for your salads, as a quick-cook side dish, or the tastiest way to green up your smoothies?

Do you like potatoes? Chips, fries, baked, or mashed? Perhaps you like the “healthier” sweet potato chips and fries?

Do you love black beans in your burritos?

Do you like second helpings or “super” serving sizes?

These days, we have at least three factors working against us:

  1. the ubiquity of high oxalate foods,
  2. the frequency with which we eat them (it’s easier than ever to make potato chips or french fries daily fare), and also
  3. restaurant portion sizes that get us in trouble.

Eating quick-and-easy means reaching for nuts, peanut butter, or chips. Eating out, well . . .

Hard-to-Resist Super-Sized French Fries

Many restaurants jumbo size their standard french fry order as cheap advertising. You see, it costs them only pennies to wow the customer and offer a memorable experience that they’ll tell others about. Take Five Guys, for example*. Famous for giant piles of fries, their regular fry order weighs a gargantuan 411 grams—almost a pound! About 5 years ago, Five Guys expanded their menu with a “Little” order of fries. Weighing in at 227 grams (½ lb.) a “Little” Fries order is still too big: it’s easily enough for two people.

Instead of standard fries, try my oven-fried turnips

Unfortunately, your body takes a hit with the 100 mg of oxalate that comes with the “Little” fry order. If they were made with sweet potatoes: a “Little” fry order would deliver 164mg of oxalate.* For perspective, consider this: 150mg is the amount that medical researchers claim is our typical all-day consumption of oxalate in food. Does that ring true to you? On the days you have the “Little” fry order, is that the only plant food you eat all day? (Hint: add at least an additional 12mg oxalate from the white hamburger bun with sesame seeds on it, and another 3 – 5mg for toppings such as tomatoes.)

The ubiquity of “would you like fries or chips with that?” encourages us all to make potatoes a too-frequent, regular thing. But, you don’t need to eat out frequently to get into a high oxalate food habit, it can happen to anyone. Just fall in love with the wrong food. It’s sort of arbitrary. Few people seem to understand that the danger of regular excessive oxalate consumption is not just theoretical. Check out Sam’s story.

Unlucky in Love: Sam

Sam was an author, naturopath, amateur tennis player, and successful business man. He loved the flavor of buckwheat. He ate it every single day, for many decades. He also liked spinach omelets, and frequently ate almonds as snacks. On Sam’s typical day, these three foods alone could have contributed at least 775 mg of oxalate to his total intake (1 cup cooked buckwheat 180mgª & 3/4 cup raw baby spinach 480mg § & 1 oz. almonds 115mg §). Despite his expertise in health, Sam was unaware of the damaging effects of eating high oxalate foods, nor did he know that his go-to foods have so much oxalate.

Let’s fill in the rest of his daily diet. In addition to these favored anchor foods, it’s possible that he also ate:

(at least) one slice of multi-grain wheat bread (16mg) with his omelet,
at least ¼ tsp black pepper (4mg) over the course of the day;
a cup of black or green tea (25mg)
a few carrot or celery sticks (15mg);
a peanut butter snack (50mg / 2 T);
½ c of brown rice with dinner (10mg);
green beans (18mg/ ½ c boiled)
a tiny bite of milk chocolate for a treat or dessert (20mg/½ oz.).

A day that included all these foods would bring Sam to a total intake of 920 mg of oxalate. That is a potentially dangerous oxalate level in only a modest amount of food.

The Trouble with Healthy Food

I learned about Sam’s love of buckwheat, almonds, and spinach omelets on Dec. 29, 2015. Sam called me after reading my article: “When Heathy Isn’t”. He told me that he had been struggling with a set of problems he called “chronic break down”—including attacks of severe muscle soreness in his upper back, neck, and his upper buttock muscles. The debilitating pain would come and then disappear without rhyme or reason. Sometimes it involved severe muscle weakness that would make movement nearly impossible. This was distressing and embarrassing to an accomplished tennis player and health expert.

After reading my article Sam had a “eureka” moment. At last, in his late 60s, he learned of a critical missing piece in his understanding of the health effects of foods. Sadly, Sam died less than 2 years later, despite his devotion to healthy living, a happy marriage, and a thriving business. Based on our conversations, I know he believed that a lifetime of high-oxalate eating contributed to his early passing.

Counting a Daze-Worth of Oxalate

Take a look at the table below. It imagines a diet based on Sam’s favorite meals and snacks and compares it with another menu that some other man might have selected. Neither person selected his foods with oxalate in mind, but the difference is astounding – Sam’s diet is 14 times higher in oxalate. A full gram of oxalate in a day is a toxic level of oxalate exposure!

Who’s Looking Out for Us?

Health authorities have dropped the ball. As a result, no one is paying attention to the oxalates in our food and how the amount we’re eating has been creeping up and up and up. We’re paying a price for our ignorance about what we’re eating.

Don’t wait for some official warning. Oxalate is a toxin. Unlike most environmental poisons, this is one toxin that is within your control to avoid. Don’t let your health depend on a roll of the dice. Get started.

Note: You may have good reasons for avoiding Rice Chex™, Shake ’N Bake™, or other packaged foods (check out my recipes!). The point here is that commonly eaten foods can be very high or very low in oxalate, and nobody is aware of the difference.

Our Oxalate-Loaded Environment: No Seasons, No Awareness

I’m very excited to announce a new article in the Journal of Evolution and Health: “Lost Seasonality and Overconsumption of Plants: Risking Oxalate Toxicity” by me: Sally K. Norton. Link http://jevohealth.com/cgi/viewcontent.cgi?article=1085&context=journal (or you can download it from my site)

Please read and share this heavily referenced, peer-reviewed article. Perhaps it will help us all see how we’re eating today in a new light. The article offers an up-to-date synopsis of what we know about oxalates, based on my extensive review of the scientific literature.

The rest of this blog post revisits and expands on the key points from the article.

Oxalate Toxicity Illness

Once you realize that oxalate in foods is at the root of your suffering, you can’t help but wonder: Why am I in trouble with oxalate? Why is this happening? Hasn’t oxalate been around forever? Is there something wrong with me that made me especially vulnerable to the oxalate problem? Why me? – this is the classic victim question. Yes, you are a victim, but of what? I say you are a victim of modern progress, affluence, cultural trends, and generalized ignorance of oxalate science; hear me out. . .

Oxalate-related illness is, in general, a problem of: 1) oxalate exposure and 2) bioaccumulation inside of our bodies. This is so, regardless if the effects of this exposure and accumulation surface as arthritis, digestive problems, headaches, pain issues, skin trouble, bad sleep, or kidney stones.

The One-Two Punch

Let’s consider that modern eating patterns douse us in oxalate far too routinely. (Missed any meals recently?) When the continuous oxalate marinade (daily low to moderate doses) includes occasional pulses of extreme doses (as in a spinach smoothie or a bag of almonds), accumulation is bound to occur. This combination – constant eating of plant foods (like bread and spices) interspersed with the occasional dark chocolate bar or spinach salad – is especially good at promoting the build-up of minute oxalate deposits in the body. The speed and extent of this process may be what separates the seemingly unaffected from those of us with joint, digestive, brain and neurological issues. Beyond just the level of oxalate intake, these factors seem to be key determinants of how fast and how extensively oxalate toxicity develops:

  • oxalate absorption
    • (many dietary factors and other changing conditions will affect the amount that gets inside the body),
    • it is generally much higher then scientists used to think
  • gut health, and
  • internal inflammation.

Never a Break

Never before has it been so easy to obtain oxalate-heavy foods. At the same time, we’ve become nibblers (or grazers) who believe that six small meals daily make for a healthy and acceptable meal pattern. We never take off from eating plant foods. We used to have those breaks: things called winter, or drought, or crop failure, or high-holy fasting days. And, of course when we’re eating oxalate, we have no idea that we are doing it; no one has bothered to tell us. Hardly anyone is aware of the presence of oxalate in our beloved foods and its potential dangers. Never have we been so at risk for slow, low-grade health damage thanks to our modern food choices, constant eating, and unawareness.

Global Food System Has Erased the Seasons

Winter is gone. No longer do we subsist on ham, onions, pickles, and white biscuits from January to March. Now, fresh green spinach, fruits, and nuts of all kinds can be had any day of the year. Our modern food scene is slick and sexy (packaged with grand promises), tasty and super-convenient, affordable, and . . . risky.

You can get nearly anything you could want, seven days a week, 365 days a year. Refrigerated trucks, the interstate highway system, inter-continental shipping, and the 24-hour grocery store all work to meet the demand for affordable, constant access to any and all foods. We usually see this as a great victory of modern commerce, but the downside… well, it has made it possible to bypass and disarm the body’s own defenses against what was historically only periodic over-dosing on high oxalate plant foods. That’s my guess, anyway. There is not any good research on the amount of oxalate in our diets and how this has changed.

Getting Plenty of Neo Foods

Envision some modern basics: tea, chips, fries, and almond milk. . . Finding our way to a daily cup of tea was never this easy! No longer do you have to haul water from the river, or fire up a wood stove. Potato chips? They were mass-produced for home consumption only recently. And french fries? Routine access to fries came with the invention of cheap (and addictive) fast food in the 1950s. That helped to launch the new and steadily expanding practice of eating meals away from home,  not just on special occasions but as part normal daily life. Restaurants eagerly offer hash browns, potato chips, fries, and mashed (or baked) potatoes as the classic side. (Too cheap, popular, and profitable to resist.)

Almond and rice beverages? These new-fangled products became commercially available and widely distributed only about 10 years ago (and have been growing in popularity). And please note: These faux “milks” are marketed as a fitting substitute for calcium-rich dairy milk. They are not. Not only do they contain oxalate (which real milk does not), but they lack milk’s ability to protect against oxalate absorption offered by dairy calcium.

Normal variability in what and when we eat, and restrictions that once came with the seasons and periodic food scarcity, are all gone in modern affluent societies. Easy, routine access to tasty oxalate-ridden foods has created a new situation for our bodies. The constant bombardment of our bodies by oxalate is an escalating, and uniquely problematic source of toxic stress in 21st Century life. It’s as if it were Thanksgiving Day, every day. The harvest is in and abundance is the theme of the moment. Have whatever you like; if its “healthy”—have a lot of it, frequently.

Modern Concepts of Health Foods

Modern dietary approaches have placed great emphasis on the health benefits of vegetables, nuts, chocolate, and spices, despite their being high in oxalate. There is a great deal of encouragement, pressure even, to eat greens, nuts, fruits, and other “whole” plant foods. We constantly hear that the sure path to complete health is the “plant based” diet. If it doesn’t work, you are just not trying hard enough… so just keep selecting antioxidant-rich “health foods”.

In this culture, how would anyone ever begin to suspect something amiss with this moral and fail-safe approach to eating? They don’t, not until they have exhausted every other possible explanation for why they hurt or can’t think well or get restless sleep… but I digress.

Accumulation of Oxalate

Any tissue of the body can end up with oxalate deposits, not just the kidneys and other parts of the urinary system. But how and why? This question has been posed, but rarely studied, at least since 1940 when a London coroner found oxalate crystals at the site of a brain aneurysm in a 61-year old woman.1 The prevailing theory in medical science is that the entire drainage system had to be broken down (persistent kidney failure) for oxalate to collect in non-renal tissues. Yet the exceptions to this rule are many—littered across the various fields of research.

Pathologists report finding oxalate deposits in eyes, arteries, hearts, skin, wherever—despite functional, healthy kidneys. We find this in cases of acute oxalate poisoning among patients who have tried to commit suicide with oxalic acid washing powders or ethylene glycol anti-freeze (ethylene glycol is a metabolic precursor that becomes oxalate in the body), and in cases of genetic disorders that cause excessive internal production of oxalate. But we also find these deposits in the chronically ill, in previously injured tissues, and in perfectly healthy people.

Stuck in Catch Mode

The scientific evidence suggests that the body is good at a game of “catch and release”. This is a process in which healthy cells take on minute oxalate crystals with the intention of this being a temporary accommodation. When the coast is clear and conditions right, cells recruit immune cells to help them dismantle and release the sequestered oxalate and send it off for excretion. Our diets, however, are pitching oxalate steadily (and at quite a clip). The effect is that the catch and release cycle gets stuck in “catch” mode. Cells holding oxalate attract more oxalate crystals which then become ever-present because oxalate is ever-present in so many of our favored foods. Injured cells or cell fragments passively get saddled with crystals that not only persist but grow, for years and decades.

We don’t see the inevitable but invisible nano-deposits and non-crystalline traces in cells throughout the body. The trained pathologist can see the much larger micro-crystals (when the tissue are fresh and properly handled, and when using the appropriate stain and polarized light). But the hunt for these troublesome contaminants isn’t done in typical tissue biopsy and tissues are usually not fresh. (The central concern being the detection of cancerous cells.) The body, however, is aware of oxalate. It is designed to unload these toxic traces, if it can only get the opportunity.

Let the Toxin Go

The cells await the conditions necessary for dismantling and releasing crystals. It would seem that tissues may need several days of very low-level oxalate intake to start the slow process of dismantling, dissolving, and unloading these nano-deposits. (In one study, looking at rat kidneys, this process was underway in just a matter of days. In another study, complete dissolution of a crystal took five or more weeks to complete).

The way we eat, the “release” conditions don’t come very often or for very long. The next time someone tells you “you’re full of it” they might be right!  And they might be full of it themselves!

Will today’s natural foods fix our health problems?

Paleo bread made from high-oxalate ingredients

Today’s health crisis. Have you noticed it? Obesity, insulin resistance, diabetes, kidney disease, cancer, infertility, behavioral and mood problems, poor sleep, and PAIN. Do you know anyone with any of these problems? Yes, you do, even if you are not aware of it. And, the suffering is happening at younger and younger ages. Our kids are in trouble, we’re all in trouble.

It is expensive to be sick. Both time and money are sucked out of our lives, not to mention the fun. And what about the bigger picture all around us? Perhaps you’ve noticed that poor health is threatening social and economic stability, world-wide.

Eating Better?

So, what are we doing about it? Eating better? Going “natural”? Yes, we are indeed eating more veggies and less meat, less fat too. We’re swearing off gluten and A bag of cheese-like "healthy food" substance made from almonds.milk, going for alternative low-carb or gluten-free breads, alternative “milk”, and fake cheese. Is this going to save us? I say no. Hear about one reason why this approach is not a great solution: in this video about oxalate toxicity from natural foods.

My Ancestral Health Symposium Presentation

In September, I had an opportunity to offer an address to the Ancestral Health Society. This presentation argues that many of today’s health foods are having the opposite of the intended effect. Rather than making us healthier, the superfood food craze could, like the holy war against saturated fat, be launching another public health calamity, as expensive and unpleasant as the current diabetes and obesity explosion.

Here are some highlights from this talk:

Chocolate is now “produce” at Walmart

  • Low-level toxicity and nutrient deficiencies make us sick.
  • One of the most potent toxins that people regularly ingest in the contemporary diet is oxalate.
  • Oxalate causes nutrient depletion AND toxicity in the body.
  • Oxalate, when purified, can rapidly kill a person.
  • It was even the poison of interest in the very first experimental toxicology study published in 1823 in England, because it caused several accidental deaths in the early1800s.
  • Many of the plant foods we like to think are good for us have enough oxalate to harm our health in much more subtle ways.
  • These natural foods might even cause mechanical abrasion to your digestive tract do to the “needle effect”.
  • Oxalate can collect in your tissues.
  • The availability of high oxalate foods we see today is unprecedented.
  • Today we are eating oxalate in amounts that cause us to begin accumulating oxalate in our arteries, bones, thyroid, breasts, and kidneys.
  • When you eat “normal” levels of oxalate, you “maintain” and grow the oxalate deposits that have already started in your body.
  • Medical and nutrition authorities have virtually no awareness of the threat of biological toxicity posed by over-exposure to oxalate and its precursors. They are not paying attention to the increase in our use of high oxalate foods.
  • Going low destabilizes oxalate in the body, and helps it move out.
  • Going low can prevent and even reverse a lot of common complaints, as proven by thousands of reports from real people in the real world (members of the VP Foundation, Participants in the Trying Low Oxalates online groups, my own clients and followers, and many others).

Action Items for You

  • Please watch the video, it is only 39 minutes and is packed with helpful images and information that will make you want to share it and watch it a second time.
  • Please give it a thumbs up.
  • Share with those you love.
  • Let me know what you think.

… and

  • Skip the swiss chard and almonds.

The fewer toxins in your body the better, even the natural ones!

“From a practical point of view, it would be better to avoid oxalate-rich foods than to take measures to neutralize the effect of oxalic acid, especially when other sources of green vegetables are available.”
