Yeah i dont think its right, nothing wrong with milk, butter etc, essential cooking items and pregnant women, older women, children all should have high diary products.
If a tax needs added then add it to the real problem, crisps, processed food, chocolate, sweets etc, the obestity problem isnt caused by people drinking too much milk, its caused by all the other stuff. Yes cheese etc is fattening, but it would be much better to pick on items which are processed, or quick to make. If you tax basic ingrediants lt will mean even more people who cant cook and if they have to choose between tax on several items to make something or one item like pizza, or chips then they will go for the far more unhealthy option.
To be honest the whole idea of adding ANOTHER tax is beyond me, are be not struugling enough already? but if it does happen then i could reather certain ingerdiants not be included, like cheese, butter, milk.
Infact it would affect me much as we used completley skimmed milk and occasionally semi skimmed, i dont use butter unless im cooking but we do have cheese. but still, i think pre-made foods should be targeted not ingrediants.
