Researchers find a western-style diet can impair brain function

After a week on a high fat, high added sugar diet, volunteers scored worse on memory tests

Consuming a western diet for as little as one week can subtly impair brain function and encourage slim and otherwise healthy young people to overeat, scientists claim.

Researchers found that after seven days on a high fat, high added sugar diet, volunteers in their 20s scored worse on memory tests and found junk food more desirable immediately after they had finished a meal.
