@Ivan83 - I can understand your cynicism and I am no great fan of processed foods either. But we have to remember that it is because of food scientists that we have a safe, stable and bountiful food supply. It was not that long ago that people world wide had to contend with hunger and food born illnesses on a regular basis.
I know so many people that rail against processed foods and the whole idea of food science in general. Food is natural and automatic they say. We don't need to tinker with nature. But the flip side of this is that nature is unpredictable and the only way to ensure a necessary and consistent food supply is to apply the principles of science. So I have a lot of respect for the kinds of work that they do, even when it leads to things like Mountain Dew Code Red.
