Indeed. Added sugar and high fructose corn syrup is in everything. I have to go out of my way to find a brand of bread that doesn't have added high fructose corn syrup. It's ridiculous.
Also buying fresh vegtables and cooking instead of buying ready made dishes helps.
Even without human interference, fruit can actually be bad for you if you eat it at the wrong time and in the wrong quantities - fructose has the same effect as sugar - but now we are basically getting into nutrition more generally which is a tricky subject. Fruit still comes with many other nutritional benefits compared to sugary manufactured snacks, and even fibre that make it worth while (note that orange juice, as minimally as we are processing the fruit, still allows you to consume it in unnatural quantity and concentration, which can be very bad).
