Fat Alert

Feel sluggish after breakfast or lunch? Researchers suggest it may be because you ate too much fat.

A new study published in the journal Sleep suggests that when otherwise healthy, non-obese adults eat heavy, fatty foods (think burgers, deep-fried foods and greasy, cheesy pizza) during the day it can impair alertness.

Interestingly, the study subjects tended to fare better on the alertness scale when they ate carbohydrates and other foods that were not high in fat. Protein consumption didn’t seem to have a positive or negative impact on the study subjects.

Researchers noted that there are implications beyond packing on the calories for eating too much fat. It can affect productivity and even impair public safety by diminishing mental acuity.
