It all began in the 1970s with the first publication of “The Seven Countries Study .” The research looked at the incidences of saturated fat intake and heart disease among 12,763 men from around the globe and showed a correlation between the two. This idea took flight around 40 years ago. Now this “common sense fact” has become so widely accepted that a lot of people who want to improve their diet start by purchasing skim milk, ditching their egg yolks, and beginning a life free of steak, pork, and butter. Unfortunately, the study was deeply flawed: It didn’t take into account important factors like smoking rates, sugar consumption, and exercise levels, and it left out an awful lot of data from other countries that contradicted the conclusions.
Fats are one the most necessary requirements for our survival. Eating good fats rich in Omega-3 instead of highly refined carbohydrates reduces harmful LDL cholesterol and improves the cholesterol profile. It also lowers triglycerides.
Omega-3 fatty acids may help prevent and even treat heart disease and stroke. In addition to reducing blood pressure, raising HDL, and lowering triglycerides, polyunsaturated fats may help prevent lethal heart rhythms from arising. Evidence also suggests they may help reduce the need for corticosteroid medications in people with rheumatoid arthritis. Studies linking omega-3s to a wide range of other health improvements, including reducing risk of dementia, are inconclusive, and some of them have major flaws, according to a systematic review of the evidence by the Agency for Healthcare Research and Quality.
To think of it, humans have always included and consumed a lot of fat in their diet and have built strong armies and healthy, intelligent civilizations. We need to go back to the roots and understand what they ate and how they lived such healthy lives.
