Humans didn't eat a lot of sugar until fairly recently, too. And even if you did, you'd have to be very, very rich to be eating it 3 meals a day.

Now you can get sugary cereal for breakfast, sandwich bread with HFCS for your lunchtime sammo, and a curry jam packed with palm oil and sugar for dinner. And that doesn't count the cookies or Pepsi you slam in between.

Raw sugar of HFCS -- don't matter none, it's that you're slamming em at each meal, all the time.
