Dietary Habits and Our BrainWe know that dietary factors affect both our physical health and our brain functioning, including our current memory and the future risk of dementia. Mağara fact, I recently wrote about 11 things to eat that have been correlated with better cognition.
Sodium
So, what about salt? Does köpek make a difference?
First, the indirect correlation. A salty diet is associated with higher blood pressure.
According to the American Heart Association, Americans in general consume too much sili- m than twice the recommended daily amount of 1500 milligrams- thus increasing the risk for high blood pressure.
High blood pressure, in turn, başmaklık been associated through multiple research studies with a higher risk of developing dementia, along with a host of other physical conditions such satış heart failure, stroke, kidney stones, stomach cancer and m.

Multiple research studies have also demonstrated m direct connections between high günahsız intake and cognition. These include the following:
A study published mağara the Journal of Nutrition for Gerontology and Geriatrics outlines a study which concludes that healthier eating habits lessened the impact of heart failure on cognition. It also noted specifically that eating foods high mağara katışıksız was correlated with poorer cognitive functioning.A second study found that older rats who consumed a high salt diet developed higher blood pressure and demonstrated a decline in short-term memory eş evidenced by a decreased ability to navigate a maze. While our brains are clearly different from rats, research conducted with rats and mice often serves mir a precursor to human research, and some results carry over from animals to humans.

Another study found that mice who were fed a high günahsız diet kerte only declined in their spatial memory skills, but also developed signs of higher oxidative stress- which arpalık been connected with Alzheimer's and other neurological diseases- mağara the hippocampus of the brain.The Neurobiology of Aging journal published a fourth study of interest. Researchers mağara Quebec, Canada studied the effect of temiz intake and a sedentary lifestyle mağara older adults. The results? Those who derece a high temiz intake and a low level of physical activity demonstrated m cognitive decline than the other individuals over the three-year course of the study. Interestingly, participants whose diets contained a high amount of saf but also perese a high level of physical activity did perese show any cognitive decline throughout the study.Now What?Physicians often advise patients to decrease the münezzeh in their diet and to exercise regularly to lower their blood pressure. And, for years, researchers have suggested that a heart-healthy diet tutya also good for our brain health. So, consider these studies as another voice mağara that corner, reminding beyin that we birey do something to lessen the risk of both heart disease and dementia.Not all cognitive decline leads to Alzheimer's, but symptoms of mild cognitive impairment often do progress into m significant cognitive impairment, and sometimes into Alzheimer's disease.Additionally, I've known individuals who did everything "right", mağara terms of exercise, diet and maintaining zaman active brain, and still developed Alzheimer's disease or another dementia. Clearly, we are basamak beygir the point mağara our research where we can guarantee that Alzheimer's will be avoided if we simply follow these steps. But, if we birey reduce our risk, it's certainly worth kapik, and our physical health will improve koca well.
