Too Much Spinach?
It’s about time that we talked about oxalates.

The human body is incredibly complex. A full understanding of how it works and how it’s all balanced together is still far beyond the reach of modern science. And so there’s a lot to talk about.
Oxalates are natural chemicals in your body, and are also found in some foods, such as (you guessed it) spinach, almonds, peanuts, potatoes, chocolate, carrots and raspberries.
Oxalates have become a topic of conversation partly because of the popularity of the book Toxic Superfoods by Sally K. Norton. But the book has also been highly criticized as more health-hype than health-fact.
The fact of the matter is that oxalates have been a concern in the health field for more than a century. As early as 1933, migraine among other things was being connected with too much oxalate intake.
As with anything, there’s too much of a good thing. It’s not so much controversial that too many oxalates collecting in the body can cause problems (such as, most famously, kidney stones).
The controversy instead centres around just how common oxalate problems are, and just what kinds of health conditions they can cause. Some of the criticisms around Norton’s book, for example, are that she seems to associate almost every health condition and the fall of western civilization to eating too many oxalates.
I exaggerate, of course, and I think that some of these criticisms are a bit unfair as well. The fact is that our bodies are indeed complex, and doctors are often very hesitant to blame health issues on diet unless the connection is direct and obvious.
The nature of this controversy means that, if you’re interested in investigating it, you’ll need to do more than watch a couple of videos on YouTube. It will take some time to look at various sides of the issue, and to take a good look at what your body is telling you.
Norton is suggesting (among other things) that in many ways modern health crazes are pushing our bodies out of balance. To suddenly load up on spinach smoothies may indeed be too much of a good thing. And certain diets, in their effort to duplicate and feed our every craving, end up causing two problems as they solve one.
Even the question of which foods will cause problems with your oxalates can be complicated. But if you’re dealing with health issues and want to investigate diet solutions, I recommend looking into this question and making your own decision. Take a look at some of the foods commonly said to be high in oxalates. And do some serious reading of the research.
Norton’s book is one resource you can check out. But be warned that this is not a light, motivational self-help read. To understand her side of the issue, I strongly recommend you take the time needed to understand it. And she does address some of the concerns of her opponents – you can decide if her answers are helpful/satisfactory.
This issue raises some important general questions. Is it hopeless to try to improve our diets? Will the research of 2029 completely change diet recommendations for migraine and other similar conditions that we had in 2024? How can we make the best decisions now without being caught in fads that might not serve us well? Science is a moving target, and it should be, since it’s based on questioning and retesting. But we still want to make the best decisions we can by wisely interpreting the information we have today.
There are some rules that seem timeless, and moderation is one of them. And that may indeed be part of the issue with oxalates. But the human body is much more complex than a “just do this” diet can address. Your body changes as you get older. Rapid industrialization is changing the food that is available to us, meaning that the nutrients in common foods may not be what it was a hundred years ago. Migraine sufferers have specific needs that may not be addressed by “fad diets” anyway.
There are general rules that can be helpful. But in the world today, don’t expect a silver bullet that will solve all your health issues. It’s going to take some work. But we’re up for it!
