Growing up poor, my house and the houses of my friends basically had three options – milk, sugary drinks and water. And milk was rationed like it was war.
Sugary drinks are cheap, shelf-stable and dense with calories.
When you don't have a lot of better options for calories, they fit the bill. It's not preference, it's survival.
We know that despite the difference in sugary drink consumption, obesity doesn't vary in population sets [0]:
"… evidence from 4 nationally representative US surveys has shown that populations who frequently consume sugar-sweetened beverages do not have a higher obesity rate or risk than populations who infrequently consume these beverages."
… which makes sense if sugary drinks are replacing calories that would otherwise be found in better foods.
I'd recommend spending some time with working-class people before adopting any belief which treats them as fundamentally different than higher-income people in terms of preferences.
Sugary beverages have been correlated with obesity and weight gain in multiple other studies, however. One thing that’s interesting having read a few of these is that there are often contradictory results when doing meta-analysis of multiple studies.
Having empathy on a subject is definitely important. But it’s also important not to take an argument personally and not let personal anecdotes influence you more than they warrant. We’re not really talking about every poor person here and we’re not talking about your childhood friends. We’re mostly talking in generalizations about broad demographic trends.
The importance of the study I linked is that it examined consumption in low-income populations, and not the broader public.
As my point was that sugary drinks are often a form of caloric replacement, and not preference, for low-income people – as was my lived experience – the study was relevant as it's the type of result you'd expect were that to be the case.
I was not arguing that sugary drinks don't contribute to obesity in the general public.
I too grew up poor and we never had soft drinks. Instead my mom would make us kool-aid on occasion. We almost exclusively ate at home, from food my mom prepared. We did have a kitchen, so if you don’t have access to a kitchen your options are limited.
