I stumbled onto this article and found it really interesting. I'll highlight the interesting bits.
|The anti-additive movement (check out the excellent and informative www.truthinlabeling.org) admits that 'natural' and 'industrially produced' glutamate are chemically the same, and treated by the body similarly. So why doesn't anyone ever complain of a headache or hyperactivity after a four cheese and tomato pizza (where there's easily as much glutamate as in an MSG-enhanced chicken chow mein)?|
| My friend Nic came round. He told me about a Japanese restaurant he'd been to that gave him headaches and a 'weird tingling in the cheeks' - until he told them to stop with the MSG. Then he was fine, he said. I nodded and I served him two tomato and chive salads; both were made using the very same ingredients but I told him one plate of tomatoes was 'organic', the other 'factory-farmed'. The organic tomatoes were far better, we agreed. These, of course, were the tomatoes doused with mono sodium glutamate. |
Then we ate mascarpone, parma ham and tomato pizza. Nic felt fine. So did I. I had ingested, I reckoned, a good six grams of MSG over the day, and probably the same again in free glutamate from the food - the equivalent of eating two 250g jars of Marmite.
Everything we eat SHOULD be in moderation. Even if you drink too much soy milk, it's actually not healthy. Moderation is the key.
