I have met and worked with many East Asians and Europeans who came to American in their 20's or older. Almost everyone of them thought American pastry and deserts are unbearably sweet. Most of them shun from soda drinks and other "food" containing high amounts of sugar. If they drink soda, they choose low- or zero-sugar kinds.
Related or not, a big percentage of American look overweight when compared to Europeans and East Asians.
