Is it possible to say "no" to sugar?

I recently came across a scary and thought provoking article on NYTimes on the harmful effects of sugar. The full material of the article is indirectly available on YouTube where Dr.Robert H. Lustig presents his case to a live audience. I recommend everyone to take a look at the article and better still the full presentation. If it stokes you, there is more here, here and here. Having done that, I have a fundamental question for the reader- is it possible for us to eliminate most if not all of our consumption of high fructose corn syrup and processed sugar?.We love our coffee, tea, soda, chocolates, cookies, sweets and everything else we eat. Remember, there is sugar everywhere. It is not just in sweet things. There is sugar  in everything we eat. Given all this, can we really stop or reduce our sugar consumption dramatically?. There are so many unknown illnesses that we worry about. We know of this one thing, sugar that can cause a lot of problems- yet we hesitate to meaningfully act on the information. Is this right?Just to be clear, natural sugars are not the problem. So eating fruits is OK. Milk contains natural sugar too. But the benifits of milk are worth the daily sugar intake hit. Its just the added and processed sugar that is a matter of concern. This includes all the aforementioned and then all your white flour concoctions, all the enriched stuff. Think about it. Maybe its time to start making changes in our lifestyle.
