That is interesting! Though it could be confusing as well. Carbs include fruits and vegetables. I think there are a lot more vegetarians now than there were in the 60s.
Is there a chart for protein?
I was born in 62, and we did eat a lot of fat in the 60s and 70s. We had bacon and eggs for breakfast, and deep fried fish for dinner, and pepperoni pizza on the weekends. Mom said she used to use a whole quart of oil every week in the 70s
We also ate lots of veggies, and we only snacked on Saturday nights. We were all SO skinny back then! The whole family super thin, despite our fatty meals. We all started gaining weight in the 80s, when dieting and health foods started to become popular.
After carefully looking at our lifestyle over the decades, I attribute our gradual weight gains not as much to our eating habits, since we didn't start gaining until after we started eating less fat and overall calories, but to our activity levels. Before the 80s, we were extremely active. We walked to school or to our friends houses. We played outside when little. When older, we worked outside tending the garden, raking leaves, etc. Plus we didn't have cable tv until the 80s. Even then, we got up to turn the channels and spent less time watching tv until the decade progressed. We weren't home in front of the tv or computer all night. We ate more before the 80s, but we burned it off. Once our activity levels slowed down, that's when we started gaining weight, despite eating healthier.
Maybe they need a chart for activity levels through the decades
