再谈 --- 低草酸盐饮食疗法
经BMOM同意,我可以用这个例子来说明一下低草酸盐饮食。
大约半年前,我贴过关于低草酸盐饮食疗法。当时是因为BMOM的事情让我贴出来的。跟BMOM再次在网上相会是在去年夏天,记得她在秋爸爸的地里问秋爸爸贝贝用了利他林后对情绪方面的控制如何?当时我不知道她就是4年前我电话过的网友,于是我悄她说:“解决情绪问题不一定首先考虑利他林等精神方面的药物,其实一些基本的补充剂可以先考虑。”
于是我们两个在悄悄话里开始了聊孩子的情况。BMOM做生物疗法几年了,无麦奶无糖的饮食疗法做得很好,但是孩子情绪还是很大。我发现她孩子的饮食可能有问题,于是叫她给了我清单。结果发现孩子吃的东西里面含草酸盐的食物较多。于是我们开始了低草酸盐饮食以及用一些益生菌(VSL#3牌子)和补充剂来处理。过了一段时间她说她孩子的情绪得到较大的改善,她非常欣喜!
所以我想,这里把这个事情谈一下,引起大家的重视---禁食重要,不同的禁食方法对不同的孩子有不同的疗效。低草酸盐禁食会改善一些酵母菌引起的类似的问题(比如行为问题,情绪问题),还有尿频(遗尿)等。刚好BMOM贴了SUSAN OWENS的关于低草酸盐饮食的对话,我就把它放在下面,希望对大家有用。
这里说的低草酸盐饮食疗法比ABA管用,是针对B的个体情况而言,先申明,避免口水仗。
以下是引用BMom在2011/1/12 上午 08:56:08的发言:

低草酸饮食对B的情绪和行为帮助较大. 比ABA管用. 多谢Kwen妈妈指点迷津.

> low-oxalate diet. We did a pilot study with 7 kids.
> All 7 were high in oxalates, and started the diet.
> They had problems with frequent urination, GI pain,
> etc. within a couple hours of eating. They had changes

> with the diet. A lot of the things we've been calling
> yeasty behaviors go away with a low-oxalate diet. A
> lot of these kids had trouble taking DMG and TMG,
> glycine in general. We saw problems with
> constipation/diarrhea in these kids before the diet,
> even after being treated by GI docs. A lot of these
> children had trouble when introducing nuts, legumes,
> soy. A lot of these kids craved high-oxalate foods.
>
> Q: What foods are high in oxalates?
>
> A: Nuts, legumes, green leafy vegetables, spinach,
> chard, black raspberry, soy, pecans, refried beans,
> almond, beet, okra, sweet potatoes, chocolate, cocoa,
> a lot of different teas, black current, dried fig,
> canned fruit salad, concord grapes, rubarb, tamarillo,

> It makes sense to try low-oxalate diet for at least a

> Chocolate and peanut butter are high in oxalates,

> A: Is he trying a low-oxalate diet yet? (no, just scd,

> A: Issues in speech (that's the area we see improve

>
> A: Astonishingly some kids show improvements in just a

> Oxalates are oxidants. And oxidant creates oxidative

>
> A: We have to rely on our bacteria – it breaks

>
> A: We have had folks doing both LDN and low-oxalate

>
> Q: On the diet, is the ultimate goal to do LO foods

> foods that child tolerates and never high oxalate?
>
> A: We're trying to let the children tell us. We know

>
> Q: You mentioned issues with speech. Have you had

>
> A: We haven't had someone non-verbal try it yet. We

>
> Q: Can you talk a little more about children who have

>
> A: The idea of taking calcium in the meal is to bind

> The bound calcium in spinach is not a problem, it's
