In a study published in the journal Neurobiology of Aging, reseachers looked at salt consumption and activity level of 1,262 healthy Quebec residing male and females adults aged between 67 and 84 years over a three years period.  Participants who consumed no more than 2,263 mg of salt per day were classified as low sodium intakers, those consuming between 2,264 and 3,090 mg/day were classified as mid-sodium intakers, and high-sodium intake referred to intaking at least  3,090 mg/day.  According to Dr. Fiocco, ``The results of our study showed that a diet high in sodium, combined with little exercise, was especially detrimental to cognitive performance of older adults.  But the good news is that sedentary older adults showed no cognitive decline over the three years that we followed them if they had low sodium intake.``  He made a point of noting that eating high salt snacks while surfing the web and watching T.V. is not just harmful to your heart, but also to your mind. Personally, if high sodium and low physical activity levels are detrimental to cognitive abilities in older adults, I would assume that these habits are also not advantageous to younger adults.  Let\'s start good habitats when we are young, because as the saying goes, old habits die hard.
