Food was a lot healthier back in those days and people didn't have as much of a sedentary lifestyle like now.
No it was not. People actually thought McDonald's and microwaveable folds were healthy. Generations of Families raised their kids on processed crap. The main difference now is people didn't have entertainment in their faces 24/7. Kids played outside all day, had gym class until they graduated high school, people walked a lot. If you wanted to socialize you have to go outside and find an activity. Cartoons came on once a week on Saturday so in between you had to make your own fun. There was no internet. You could read a book, but you had to walk to the library to get it.
In the 90s we'd play soccer hours outside. Nowadays kids would rather spend their time socializing online or sitting in front of a screen. Plus people ate smaller portions back then but they still ate like crap.
Trust me food is healthier now. It's less processed and they use better ingredients, people are starting to shun fast and processed food.
We as a country still need to learn how to limit our portions. The reason why we are fat now as a country is because 80s and 90s kids who ate large amounts of food stopped exercising once we got older and once our parents thought we were safer indoors than outside. People now actually shame parents for letting their kids run around past the front yard unsupervised.
Gym class disappeared in the 2000s. We got lazier and ate more of the bad foods we thought were good but we arent burning anything off. 80s and 90s kids who ate one slice of pizza and a glass of soda then went outside for three hours got older and are now raising 00s kids who eat one slice of pizza and another out of boredom with 3 glasses of soda while playing on their iPad for three hours.
Not to mention the anti bullying body shaming stuff out now. Back then if you were fat or goofy even your teachers made fun of you. You stayed fit to stay off people's radar.Let a teacher call a kid fat now and live to talk about it
