No, I don't eat clay. I don't wash my organic lettuce, though (hahaha!) - does that count?
I don't put a lot of stock in the notion that anti-nutrients are by default a bad thing when they are in low amounts like is found in many nuts as well as most fruits & veggies. I don't eat legumes (which are full of anti-nutrients).
It's worth noting that the tannins, for example, are not harmful in low doses, and there is evidence they are helpful. They also flush right thru your system, so eating a salad at one meal and a steak at the next will have no effect on your body's ability to up-take all the nutrients in the meat. In fact, eating a salad & steak in the same meal doesn't hinder your body's ability to up-take nutrients in the meat (or the salad).
Now, eating a salad with a pile of red beans on top will cause problems in nutrient up-take, because red beans are very high (though not toxically high) in tannins. Remember, many of the anti-nutrients (like tannin, since I've been using that as an example) require HIGH doses before they really interfere with nutrient absorption.
That said, remember also that tannin (continuing the above example) is a metal chelator, so they are actually helpful when you need to get rid of metals in your system, and also reduces inflammation in the GI tract, kills infection in the body, and protects the kidneys.
Other anti-nutrients, like phytic acid, are present in food I don't eat very often (and are in low quantities). But again, their toxicity rests on dosage, and most foods don't have excess amounts. The anti-nutrient effect is often balanced by a positive effect (like those mentioned above for tannins).
Nature, in my view, won't steer you wrong.
