For those of you that managed to come to my metabolic typing sessions last week you will know this already, but for those of you who didn’t make it, here is a little snippet of info you missed out on.
Oxalic acids are a naturally occurring acid in some foods that interferes with the absorption of calcium.
Not only do you need calcium for strong bones it is also massively important for nerve transmission, muscle function and vascular contraction/ dilation.
Oxalic acids are found in seemingly healthy foods such as blackberries, beets, chard, cranberries, green peppers, rhubarb, strawberries and tomatoes, as well as several unhealthy foods ie, chocolate. The good news is that cooking destroys the oxalic acids in the food, therefore there is no need to restrict these foods as long as you eat them cooked. Alternatively if you are going to eat these foods raw I suggest taking a calcium supplement with vitamin D to help increase the absorption of calcium and calcium levels in your body.
