Key points from article :
Human mortality is largely influenced by a balance of macronutrients.
National supplies of macronutrients reveal patterns in age-specific mortality.
Optimal diet composition for reducing mortality risk varies with age.
Below the age of 25, mortality rates were closest when the total energy consisted 16% proteins & 40-45% of both fats & carbs.
But above the age of 55, the balance changed to 11% proteins, 67% carbs, and 22% fats.
“People need to get away from ‘unidimensional’ thinking [like eating less fat or avoiding carbs],” - Dr. Senior, lead researcher.
A balance of different macronutrients & not the elimination of any improves the chance of survival.
Dataset analysis of 1,879 life tables from 103 countries, between 1961 to 2016 was done.
Mortality rates were lowest when the energy supply was 3,500 kilocalories per capita per day.
