It seems that after experiments, it was found that volunteers (no one asked us) who ate a daily spoonful of the Marmite, our savoury spread of choice, appeared to have higher levels of a vital neuron chemical associated with a healthy brain. Now I like Marmite, but I do hope they didn’t make the volunteers literally eat a spoonful of it in one go, that would even make me gag in a most undignified manner. I am assuming it was given to them either spread on toast or a Ryvita or added, perhaps like I do in gravy or spag bol.
It’s something to do with the high levels of vitamin B12 in the Marmite, but it’s all a bit complicated for the likes of me, however, I expect Mr D, our regular font of all knowledge will undoubtedly be cognisant with the machinations of neurotransmitters and gamma-amino-butyric acid. I just know it’s nom nom nom and there’s not a lot wrong with any of our brains, it’s also probably the reason why Nigel muses and ponders as much as he does ………bless him!
