New Generation Pronutro is aweful!

Why did the formula for Chocolate Pronutro have to be changed?

My daughter has been home in SA, visiting from the UK for the last month. I got her some Pronutro - her favourite - but we couldn't find any Chocolate flaour lately, until we were shopping on Monday. She bought 3 big boxes to take back home with her and she is going to be dik-demoerin if it is NOT real Pronutro. Why mess with a trusted product???
