Date: March 07, 2008 12:40AM This issue has come up before, in fact I am pretty sure I've brought it up myself in the past, about the oxalates in spinach, beet greens, and chard interfering with mineral uptake. Apparently it isn't true.
[www.nature.com] So don't worry. Eat what you like for your greens. Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 07, 2008 02:09AM does this mean the recommendation to switch between different types of greens because of OA buildup is mute as well? because i really prefer spinach in my smoothies, but i keep switching around... Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 07, 2008 02:17AM I don't like spinach very much, except at a local vegan place, Horizons, where they have a spinach salad with a creamy dressing and avocados and corn. Yum. Not totally raw, but it's delicious and what I used to get when I would go (probably still is, if I go).
Oh, sorry, I was daydreaming of food (must be my fruit, low-cal fast). Anyway, I like kale better for some reason. I think spinach is good cooked, though. Conventional spinach = not as tasty! [utopiankitchen.wordpress.com] Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 07, 2008 02:40AM I still think it's better to switch around and get variety. The point is not to worry about nutrient uptake, it's all good. Your body may tell you when to stop, or when to switch. I try to get a little of all of them but I end up mostly with lettuces as the main ones.

Date: March 07, 2008 05:38PM Sorry Arugula, this article you referred to is about absorption of iron only. Oxalic acid has traditionally been linked to impaired absorption of calcium, not of iron. The article does not say anything about calcium. Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 07, 2008 05:56PM Yes, that's why excess intake of one (iron or calcium) inhibits absorption of the other. Excess dairy-induced iron deficiency anemia is extremely common in children in the US. Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 07, 2008 06:05PM Neither one easily disassociates from the oxalate forms. But the point of the article is that there is so much present in spinach that you will still get some out of it.
Rost, another reason why too much dairy is not good for Fe uptake is that there isn't much Fe in it to begin with compared to other (minimally processed) foods and that can be a problem with diets high in dairy calories, such as some SAD-like vegetarian diets.

They get it for free from the government Not *that* much though, the parents buy extra. Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 07, 2008 06:44PM Oh, the horror of that white calf food in most of America's shopping carts. The worst part is the suffering of the dairy cows and calves involved. Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 10, 2008 05:31AM That's good to hear, Arugula. Makes me wonder why other studies told another tale. I think some studies are tweaked to be conclusive of what they want to prove, depending on who is funding it.
My hemoglobin is perfect 13.5, and I haven't eaten a land creature in about 20 years. There are plenty of other sources of iron, including greens. Everyone take care. We are going to Canada for a long vacation & to visit relatives. I hope it there will be an abundance of raw, organic food. Re: iron uptake: spinach vs. kale, oxalic acid makes no difference

Date: March 10, 2008 03:05PM mmm spinach. remember where you couldn't get any? my friend and i were going to print up tshirts that said "I miss spinach." heh.
rawrrr, where are you going in canada? it's a humoungous country (i think it's the biggest in the world now that the ussr is no longer), what you can get depends on where you are. there are lots of canadians on this site, give a shout out with a new post and you'll get lots of replies.

Date: March 10, 2008 05:33PM ooh, vancouver is easy! you can visit my friend ralph at eternal abundance on commercial drive, he is a toronto local and started up an organic grocer in bc a few years ago. there is often a raw cafe running there as well. they are near a health food store with lots of raw prepared foods too. if you google vancouver raw you will find a few groups and restaurants.
i think there's some stuff in montreal but again, google and see if you find any groups. get in touch with them for the quebec lowdown. i have no idea about NS, that one might be tricky. i would bring a cooler of fruit and veg, nuts and seeds, if you can. je suis franglaise aussi, i am from toronto, i was in Nelson BC for 4 years but moved back last year to be near my family. we're close to windsor now (across the river from detroit), it's really hard to get anything here but it's farm land so summer is a ridiculously gorgeous profusion of fresh everything under the sun. it's lovely.
