SUGARY BEVERAGES MAY CAUSE ALZHEIMER'S DISEASE
Recent studies show that excessive intake of sugary beverages like sodas
may cause Alzheimer’s.
Although the exact mechanisms aren’t known, obesity and diabetes
are both associated with higher incidences of Alzheimer’s. A
recent study using the genetic mouse model showed that over a 25-week
period a diet supplemented the regular, balanced diet of half the animals
with 10% sugar water. Afterwards, they compared the metabolism, memory
skills (by means of various mazes) and brain composition of the regular
and sugar-fed mice.
The sugar-fed mice gained about 17% more weight, had higher cholesterol
levels, and developed insulin resistance. In addition, these mice
also had worse learning and memory retention and their brains contained
over twice as many amyloid plaque deposits, an anatomical hallmark of
Although the researchers cannot be certain if the increased mental impairment
resulted specifically from the higher sugar intake or higher calories
in general, these results highlight the potential risk of sugary beverages.
They note that the human equivalent of the mouse diet would be roughly
5 cans of soda per day, although since mice have a higher metabolism,
it may actually take less sugar intake in humans.
Next time you reach for that soda, consider either regular or sugar-free
flavored water instead.
