A major study found that low-fat diets are correlated to a shorter lifespan of 25 percent of the time. However, it is important to note that correlation does not necessarily point to a causal effect between both variables.
According to the Lancet study, which analyzed 135,000 adults, people who follow low-fat diets had much lower lifespans than their higher-fat diet counterparts.
The researchers say that this is why they are so much more likely to eat foods that are too much of a staple for rice, pasta and bread- rather than foods with vital nutrients.
The participants in the study with the highest intake of carbohydrates- especially refined sugars from processed foods and fizzy drinks- showed 28 percent higher risk of a shortened lifespan.
Comments On the Findings
According to Dr Andrew Mente, a researcher at McMaster University: "Our data suggests that low fat diets may cause increased cardiovascular disease.
"Loosening the restriction on total fat and saturated fat and imposing limits on carbohydrates when high to reduce intake to moderate levels would be optimal."
Dr Mahshid Dehghan, the lead researcher, said: "A high carbohydrate diet - greater than 60 per cent of energy - is associated with a higher risk of mortality."
"Higher intake of fats, including saturated fats, associated with lower risk of mortality."
Dr Aseem Malhotra, a consultant cardiologist, said that it is time for "a complete U-turn" in the UK's diet approach, and "demonization of fat."
"The sooner we do that the sooner we reverse the epidemic in obesity and diabetes and the sooner the improving health."
Jeremy Pearson, from the "British Heart Foundation" said: "This study suggests that we should pay more attention to the amount of carbohydrate in our diet than we have in the past and we need to revise the guidelines."
"I do not think people should do as much as I like."
