Oxalates in greens? I have done this subject to death. Here is a blog post that points to all my former comments on the oxalates issue.
It’s another tempest in a teapot. Please show me the clinical data that healthy people need to limit oxalate-rich food. I’ve seen none. Only claims, passed around the internet. Hypothyroidism does not dictate that we avoid this very important, phenomenally nutritious class of vegetables and greens.
Goitrogens in broccoli, cabbage, kale? Read my report about goitrogens and thyroid.
Let’s use some common sense. Let’s say a food has sustained human life for thousands of years, and dozens or even hundreds of studies show it to be dramatically healthy. (I’m referring to broccoli, cabbage, and kale—the crucifers.) Let’s say we break down the many complex parts of the broccoli plant, and we find one that, when chemically isolated, is harmful.
We might do well to trust that the synergy in 100 different co-factors in that food are time-tested. How can you do a study to show that the complex interplay of factors in a powerful plant food yields long life and superior energy for humans? Scientists want to parse and isolate. If they find the heavy-hitter nutrient, they might be able to put it in a pill. Altered slightly, it might be patentable and worth $1 billion.
I’m not saying that natural, food-based supplements have no value. But nothing is going to come close to the synergistic, nearly incomprehensible effects of the plants they were derived from. The impact of the aloe vera plant on digestion, and burn healing….it’s nearly inestimable. You know this if you’ve ever cut a stalk off your aloe vera plant and applied it to a sunburn, which then doesn’t peel, and feels dramatically better, and is gone the next day. (Or if you put a stalk of your aloe vera in your green smoothie, watch what it does to your digestion that day, WOW.)
Whole plant foods are dramatically helpful for us to fuel a long, vibrant life. When you dig to the bottom of these “tempests in a teapot” controversies about anti-nutrients, you invariably learn that research shows the “anti-nutrient” to be neutral or even helpful to normal, healthy humans.
If you’ve read this blog series and are now going to avoid whole grains, cruciferous vegetables, or apple seeds, you’ve missed the point entirely. Whatever OTHER food you eat instead of that whole plant food—animal flesh, or packaged foods—has far worse than an anti-nutrient or two. They have heat-damaged carcinogenic oils, no fiber, refined sugar, chemicals from solvents and preservatives and flavor enhancers and packaging and colorings.
You’re simply far better off eating whole foods. Virtually always.
