Comments on: Smart Fuel: Spinach http://www.marksdailyapple.com/spinach/ Serving up health and fitness insights (daily, of course) with a side of irreverence.

(Cooking often destroys vitamins, and I believe maybe fiber as well, but minerals are chemical elements and aren't destroyed without nuclear reactions. They don't usually evaporate either.) I suspect what is meant here is that cooking spinach decreases its volume (it wilts a lot!), while preserving the same total amount of iron... therefore the iron is more concentrated. A serving of cooked spinach is probably a greater amount of spinach (and therefore iron) than raw because of the shrinkage that occurs during cooking. But I'm just guessing that's what's meant here.

But, I know the issues with eating it too much. For example, in this post, you said that one cup can provide 1110% of our vitamin K... but Vitamin K is not water soluble. Having such extreme amounts of it for prolonged periods of time is toxic. I love spinach… a LOT. But, I know the issues with eating it too much.

To add to the others concerns about spinach, I had heard that spinach can also contribute to gout, a very painful joint inflammation. Odd that a substance purported to have anti-inflammatory properties would contribute to an arthritis-like condition. I wonder if this and the other negative health issues are only a concern when spinach is consumed in excessive amounts, or perhaps in combination with some other, less healthy foods? I have heard that brown colas can also be a factor in kidney stone growth, and my husband, who had a kidney stone a while back, had been a regular Pepsi consumer over the years, but never really ate spinach. Passing one stone got him to give Pepsi up really quickly! I, however, have had no ill effects from my consumption of spinach (by no means excessive), and until I do, will continue to enjoy it, even more happily now, knowing how many vitamins it has!

I wasn't eating spinach so it wasn't the cause of mine, but just curious on Marks's thoughts on this?
