A sedentary lifestyle is a serious problem. Physical inactivity has increased significantly in past decades. Cost of medical care has been on the rise for many years and it will continue to increase as incidences of non-communicable diseases (NCD’s) are increasing. Life expectancy has been decreasing, and according to Dr. Colin Campbell, this generation of Americans will be the first to have a shorter life expectancy than their parents. But, only about 15% of the 1.6 million newly diagnosed NCD’s each year are caused by a sedentary lifestyle (Knight). A sedentary lifestyle is only a small part of America’s obesity problem, in the end it all comes back to nutrition: calories in versus calories …show more content…

Processed food accounts for 63% of The Standard American Diet (SAD) (Axe.) A shift in dietary habits could result in great improvements in the overall health of our nation. In particular, upping consumptions of lean meats, vegetables, fruits, and whole grains, as well as cutting out the highly-refined, nutritionless white flour, added sugars, excess sodium, and trans fats would decrease rates of NCD’s(Eagle.)
Over the past century, taste buds have evolved to become accustomed to super-sweet processed foods.In 2000 the USDA reported that each individual in the U.S. consumed over 150 pounds of sugar. That same year, Americans ate over 74 pounds of calorie-rich fats and oils. This number is estimated to be even higher in 2016. In the past, high cholesterol has been linked with excess dietary fat consumption, but new studies have shown that elevated triglycerides are not directly from fat. This “bad” cholesterol is actually produced in the liver from consumption of excess sugar
