A low-carb diet can take 4 years off your life
The fashion of the so-called "low carbohydrate diets" never goes away. Each time it comes to us with a different name, from Atkins to Keto through Dukan or Paleo. Now, a new study suggests that greatly reducing carbohydrate intake shortens life expectancy. I don't know about you, but I'm already heating water to add the spaghetti.
For this research, published in the Lancet Public Health , 15,000 American adults have been studied for 25 years. Those who have consumed a moderate amount of carbohydrates in that period – that is, they obtain between 50 and 55 percent of their energy through carbohydrates – are the ones with the longest life expectancy. Those who obtain more than 70 percent of energy from carbohydrates have a higher risk of dying earlier, as expected. What is striking is that those who get less than 40 percent of their energy from carbohydrates have an even higher risk of dying sooner.
To bring these data to specific numbers, a person whose diet includes a moderate intake of carbohydrates has a life expectancy (we are talking about the United States) of 83 years, always according to this study. For those who spend hydrates, life expectancy drops to 82 years. Those who reduce carbohydrate intake to 30 percent or less stay at 79 years. It may seem more or less tight, but four years is no nonsense.
What is behind these data? According to the researchers, people who follow low-carbohydrate diets replace that source of energy with animal meat… And both animal protein and fat are not the best allies for a long life. The same does not happen with those who follow a low-carbohydrate diet combined with proteins and fats of vegetable origin.
"Our data suggests that diets based on few carbohydrates and a lot of animal protein, so popular in North America and Europe, would be linked to a shorter life expectancy, so they should be discouraged," Dr. Sara Seidelmann told the BBC . studio head.
