Every so often a study comes out that breaks the convention. This month a large study of how diet effects mortality was released in the medical Journal, The Lancet. This study looked at over 135,000 people over 10 years.
The bottom line, people eating higher carbohydrates have higher mortality. Low fat diet also increases mortality. In other words, people who eat more fat live longer. The sweet spot for fat is 35% of your total calories.
they found that people eating high quantities of carbohydrates, which are found in breads and rice, had a nearly 30% higher risk of dying during the study than people eating a low-carb diet.
And people eating high-fat diets had a 23% lower chance of dying during the study’s seven years of follow-up compared to people who ate less fat.
The results, say the authors, point to the fact that rather than focusing on fat, health experts should be advising people to lower the amount of carbohydrates they eat. In the study, which involved 135,000 people from 18 different countries, the average diet was made up of 61% carbohydrates, 23% fat and 15% protein. In some countries, like China, south Asia and Africa, however, the amount of carbohydrates in the diet was much higher, at 63% to 67%. More than half of the people in the study consumed high-carbohydrate diets.
