Some studies are being conducted evaluating the effects of low
carb diets, such as the Atkins diet, on cognitive ability. Brain
function on a low carb diet may be impaired because glucose is
the nutrient used by the brain for energy and the brain is not
capable of storing glucose, but is depended on the bodies
production of this nutrient. Many low carb diets restrict intake
to as little as 20 grams per day, while the RDA for carbs is at
least 130 grams (taking into account the brains energy needs).
One study compared long and short term memory, spatial memory,
and visual attention of women prior to beginning a low carb
diet, post low carb diet, and after reintroduction of carbs.
Those following a low carb diet had a gradual decline in memory
performance and slower reaction time on all tests.
Interestingly, attention span was improved on the low carb diet.
Fortunately, memory skills and scores returned to normal after
carbohydrates were reintroduced. All the best, Lisa Nelson RD Be
