In reply to XXXX:
Remember the adverts prior to the 50's by doctors telling you that they smoked brand X? The food industry will tell you whatever they can to sell their products. Fruit isn't bad for you in principle, but it is full of sugar and sugar in large quantities is not good for you at all. And these days, there is sugar in everything.
Low fat Yogurt? High sugar.
Low fat anything - probably high in sugar.
Special K? Sugar.
You get the idea. The current trend in marketing is to persuade people to buy their low fat products which are laced in sugar. Naturally, the people who buy into these products also have problems losing weight if that is their goal because they crash once the sugar has been used up and end up eating more.
So you are right to be skeptical, but there is a massive problem with what is actually good for you or not.
