Unless oats are organic they are highly processed - mot traditional Porridge oats have no additives whatsoever but most of those on the supermarket shelves are not organic which means they have been subject to heavy use of pesticides. Heavy use of pesticides is correlated with dementia and Alzheimer's . If you add milk to that porridge and it's not from regenerative organic farming, then pretty soon it's likely to have come from cows fed with Bovea to reduce the methane in their cow farts and Bovea is demonstrated to contain several carcinogenic ingredients. So whilst it might make sense to say, oh it's only a little bit of insecticide coated porridge, it's only a little drop of carcinogenic milk maybe if people also thought that it's only a little bit of this, that and the other that's full of chemicals to preserve food or to give a nice foaming toothpaste, they might realise that actually they're subjecting themselves to a huge chemical load on a regular daily basis. And that's not just about sugar. As for the synthetic sweeteners - more chemicals.
Crumpets? Well, I love them and have just had two but the ingredients list is very worrying.
