Elderly cognitive decline caused by too much salt, lack of exercise
Monday 22nd August 2011
Older adults who have a diet too high in salt and fail to get enough exercise may be at a higher risk of cognitive decline, research indicates.
High-sale diets coupled with low physical activity could harm cognitive health in seniors, according to a study published online in journal Neurobiology of Aging.
The Canadian study also found that older adults who did not have a high salt intake did not suffer cognitively if they were sedentary.
Senior author Dr Carol Greenwood said: "These data are especially relevant as we know that munching on high-salt processed snacks when engaged in sedentary activities, such as watching TV or playing in front of the computer, is a frequent pastime for many adults."
This follows a study published in the European Journal of Clinical Nutrition which revealed that some 70 per cent of eight-month-old babies are taking in too much salt.
