For thousands of years, people ate saturates fats. Several decades ago, due to rise in heart disease, it was decided that saturated fats were bad, in it's place came an increase in refined carbohydrates (sugars), low-fat, low-calorie processed foods, and man-made fats such as trans-fats and polyunsaturated fats. This also increased monocultures and GMO crops to meet the rising demands of a low-fat culture. Animal protein was replaced with man made protein products, using mostly corn, soy, and wheat.
Like many things with health, when it sounds too simple, it may be missing the bigger picture. Removing animal fats and saturated fats sounded like a simple easy fix yet it made obesity, diabetes, and heart disease worse. Health and science is complex and the more we study, the more complex it becomes. Intuitively many in the science world felt that the saturated fat hypothesis was overly simplistic and now after several decades, our views on fats have shifted back to the way it's been for thousands of years.
Like views about genetics, we thought many diseases were related to environment and heredity, then for decades people who had an overly simplistic view of genes thought genes explained everything, diseases were preordained. Now that we understand more about genetics, we know it is still about environment and heredity.
Time magazine along with nearly every other media outlet published stories that it's time to end the war on fats. That the USDA guidelines about saturated fat intake was wrong. Fat is an essential nutrient and without healthy fats as a form of fuel, we turn to and crave sugar. That is the direct relationship that has harmed our health for the past few decades.
