Eating habits have also changed dramatically in the U.S. I’d like to see a study on that.
In the 50’s and 60’s did we have as many obese people? I remember having dinner, a balanced dinner at 5:30pm.
Nowadays people eat all day and well into the night, 7, 8 9pm.
Part of the problem is processed foods/meals that have high concentrations of carbs, fats and high fructose CORN syrup.
