Yes, but only because it is almost impossible to avoid
First of all we should be aiming for is a reduction in total sugar consumption. Your body is not better off just because you switch to table sugar. Recent research indicates that sugar is linked to heart disease, cancer and is addictive. There is no free lunch by switching types of sugar.
Second, HFCS is ubiquitous, it is almost impossible to avoid unless you avoid all processed foods. That should be the goal for a healthy diet! No processed food. Personally I bake my own bread and grow my own veggies.
Third, most of the corn products in the US are made with genetically modified corn (thanks to Monsanto) This GM corn has been bred to absorb the weed killer Round Up without killing the corn. Eat GM corn and you are eating Round Up (Glyphosate)
Now, Monsanto is trying to get approval for genetically modified corn that will be immune to 2,4-D, (half of the herbicide Agent Orange, used to defoliate jungles in Vietnam.) If the FDA approves this we will be eating Round Up and Agent Orange when we eat corn based products.
