Hi all so I just need some advice. My DD who's 14 (in my opinion) drinks way too much Coke Zero. She spends about a £1.15 every day (sometimes gets 2 bottles) on a 500ml bottle of coke. I personally think this is far too much and she needs to stop because of all the negative impacts and the potential risk of type 2 Diabetes.
She disagrees with me and says it's only 500ml (sometimes 1l) of coke a day but I still think it's too much as she doesn't drink water until the weekend and even then she is still drinking coke. We have stopped buying it but she still brings into the house. To be fair, she does have a pretty healthy diet, it's just the coke that worries me
Am I being unreasonable to think that she needs to change her choice of drink and become more healthy?
