Sigh, the folks suggesting sugar is a problem aren't just goofy TV diet gurus, but people like Dame Sally Davies the chief medical officer for England.
Any overegging, from whoever, that basically hands people a ready made excuse to change nothing..."ohhh, it's like crack! it's addictive! you can't help yourself !" will compound the proboem and fail utterly to be part of the solution.
It is actually quite simple to avoid too much sugar, or too much of anything that gets added to pre-made or processed foods. In the main, buy stuff that doesn't have an advert. It's often one ingredient food.
Go easy on the traditional processed foods.
Go even easier on the newer processed foods.
Avoid anything that where when you look at it, you couldn't actually guess what foodstuff was used to make it.
Drink water. Not stuff in bottles that look like they are trying hard to be seen as either healthy, or exciting.
You will save money, you will eat less sugar (and assorted other crap), you will have far better nutrition.
You don't have to be all dramatic, evangelical and "this is the first day of the rest of my life!" about it. Each week up the non processed stuff a bit, and buy a bit less of the processed stuff. Keep going, slow and steady, until you hit a balance that provides decent nutrition, has slowly got you used to cooking rather than reheating, but doesn't leave you feeling grumpily treat-free.
If people laid off the "crack" bollocks significant numbers might feel less helpless and powerless in the face of changing their diets.
