A study in the April 2013 issue of the European Journal of Preventive Cardiology showed that despite greater life expectancy, adults today are less healthy than in previous generations. Scientists analyzed data from 6000 people over 16 years that included body weight, blood pressure, total cholesterol, and HDL cholesterol. THey determined that the prevalence of overweight, obesity, increased with age in all generations, but that the increase was highest in the most recent generation. They calculated that the youngest generation is 15 years older metabolically than previous generations.
This should not be surprising considering the differences in lifestyle that include less natural living, more indoor time, less sun exposure, more toxic exposures, more stress, worse food, and more sedentary behavior.
