Is Eating Fast Food a Dementia Risk?
The health risks of eating ultraprocessed foods —including sausages and burgers as well as pizza and ice cream — are well documented. They have been shown to raise the risk of obesity, diabetes, and cancer among other ailments. (CNN.com).
In a new study, researchers followed more than 10,000 Brazilians with an average age of 51 for more than 10 years. They found that people who consumed more than 20% of their daily calories from ultra processed foods had a 28% faster cognitive decline compared with those whose intake was less than 20%. Unfortunately, that 20% is not a high threshold: just 400 calories out of the 2000 calorie diet. And most Americans are well over that, getting on average a whopping 58% of their calories from ultraprocessed foods.
