Eating Fast Food Has Been Linked to Smaller Brains
We’ve all been told ad nauseum that what we eat has a dramatic impact on out health. Most of us can rattle off a list of unhealthy foods: trans fats, processed flour, refined sugar, and so on.
And much of the attention regarding diet as it affects health has been in the area of preventing heart attacks, diabetes, or obesity-related illnesses.
There’s been a growing interest in how what we eat impacts our brains. As more research is done, scientists are discovering not only what food affects our brains, but how. A recent Australian study has come up with some startling findings.
The study contains alarming findings about the effects of an unhealthy diet on a part of the brain called the hippocampus, which has been described as the filing cabinet or the bookcase of the brain.
Researchers studied about 250 people aged in their 60s in and around Canberra and took MRI scans to measure the size of the hippocampus.
“The hippocampus is absolutely central to learning and memory,” said Associate Professor Felice Jacka, from Deakin University.
“Basically your hippocampus gets smaller as you age, and the difference we found between people with good diets and people with poor diets in terms of their left hippocampal volume, it counted for about 60 per cent of that aged-related decline. So it’s a not insubstantial amount.”
Professor Jacka said the study’s findings were more proof that a bad diet causes not only physical but also mental problems.
