As a kid, kind of ate whatever, including sugary foods, but I'm not from the US so back then I think I ate less sugar than Americans just as a function of how much sugar there is in American food

Nowadays I try to avoid eating added sugars (i.e. drink my coffee black, no soda, rarely eat deserts), but otherwise eat regular food and try to eat "real meals", like my grandparents would eat when they were my age
