Dementia includes a devastating set of brain-related symptoms, such as memory loss, which begins mildly at first and leads to disconnection from reality as knowledge of self and loved ones fades.
However, research shows that you can change your risk of brain deterioration by changing your diet.
According to Harvard Health, this means avoiding foods high in cholesterol and fat. He says that foods high in cholesterol and fat can “accelerate the formation of beta-amyloid plaques in the brain.”
And sticky protein clusters are blamed for much of the damage that occurs in the brains of people with Alzheimer’s.
LDL cholesterol builds up and damages the arteries. “We know it’s bad for your heart. There is now a lot of evidence that it’s also bad for your brain,” said Dr. Francine Grodstein, an assistant professor of medicine at Harvard Medical School and an epidemiologist at Brigham and Women’s Hospital.
In fact, a study published in the Annals found of Neurologists found that women who consumed the most saturated fats from foods like red meat and butter performed worse on tests of thinking and memory than women who consumed the least amount of these fats. The exact reason for the association between a diet rich in saturated and trans fats and poor memory is not entirely clear, but the association may be mediated by a gene called apolipoprotein E, or APOE.
This gene is related to the amount of cholesterol in the blood, and people who have a variant of this gene called APOE e4 are more likely to develop Alzheimer’s disease.
This conclusion is supported by a 2021 study published in the American Journal of Human Nutrition.
In a study of more than 1,200 people, researchers found that people with higher levels of saturated fat in their blood were more likely to develop dementia, including Alzheimer’s disease.
However, other studies present a more contrasting picture, so no clear conclusions can be drawn: for example, scientists from the University’s Nutritional Epidemiology Group used data from 500,000 people and found that eating 25 grams of processed meat per day increases the risk of disease. by 44 percent.
But their results also show that eating unprocessed red meat like beef or veal may be protective, as people who consumed 50 grams a day were 19% less likely to have dementia.
However, there has been consensus on the dangers of eating too much red meat.
For example, several studies have shown that eating large amounts of red and processed meat increases the risk of bowel cancer.
