For well over a year I have been enjoying raw kale minced in the food processor with avocado, Greek yogurt, various fruits and different protein powders. I freakin' love these 'kale puddings,' which is what I call them. They are very thick. I use 80 grams of kale each time - which is a hefty amount of kale.
The only time I did not have them with yogurt is when I used fat free ricotta or when I was avoiding daily for 2 weeks and used almond milk and drank them with a straw because almond milk thinned it out so much.
Who cares, right?
I was doing some research on iron deficiency and found that raw kale contains oxalates, which are naturally occurring substances that can interfere with the absorption of calcium.We have been having the kale/yogurt mix almost every day for over a year. (I have it 5x a week and he has it about 3x a week). Oxalic acid has been shown to "bind" with calcium, magnesium, iron, sodium and potassium in the intestine.
My husband has a low enough iron count to warrant prescription iron supplements.
We (he and I) should avoid eating calcium-rich foods like dairy at the same time as kale to prevent the formation of kidney stones. Ever see someone going through a kidney stone episode? They think they are dying. You may think they are dying. It can look like a heart attack in the making. I understand the pain is equal to childbirth (according to male explanations). Except a kidney stone is tiny.
I don't want kidney stones and I certain do not want my husband to get kidney stones. So now I have to take the kale out of the mix and put it on a cooked dinner plate. Darn. I am seeking a replacement to the kale. I thought spinach. Oxalic acid is also found in raw spinach. Bummer.
I thought Swiss chard. Oxalic acid is also found in beets, parsley, asparagus, cabbage and Swiss chard. I can't get a break with my raw leafy greens!
Do not misunderstand. We will still eat the veggies. I just have to start planning them away from dairy.
I am going to miss kale puddings. If you told me 10 years ago that today I would write I would miss kale pudding (or anything else kale), I would have laughed in your face.
Would you risk the kidney stones or would you find another ingredient for your pudding?
