Neurology: Dietary diversity reduces risk of Alzheimer's disease

Introduction: The incidence of Alzheimer's disease is now clearly increasing year by yearIt is a syndrome caused by a slow-moving brain diseaseAlzheimer's disease is characterized by a variety of advanced dermal dysfunction, involving memory, thinking, orientation, understanding, calculation, judgment, speech and learning abilityDiet has a great effect on Alzheimer's diseaseHealthy eating is known to be good for the brain, but according to a new study published online April 22, 2020 in the Journal of Neurology, the American Academy of Neurology, a healthy diet includes not only what to eat, but also what to eat together that may increase the risk of dementiaThe study, which looked at the Food Web, found that people who ate mostly highly processed meats, starchy foods such as potatoes and snacks (like biscuits and cakes) were more likely to develop dementia after a few years later than those who ate more healthy foods"Food has a complex interlinkage in a person's diet, and it is important to understand how these different connections or food networks affect the brain, and diet may be the most promising way to prevent dementia
," said study author Cecilia Samieri of the University of Bordeaux in France,Numerous studies have shown that a healthy diet may reduce an individual's risk of dementia, including eating more green leafy vegetables, berries, nuts, whole grains and fishMany studies have focused on the quantity and frequency of food, and the study further looks at food webs and finds important differences in the way food is consumed in common between people with dementia and those who do notstudy involved 209 people with Alzheimer's disease with an average age of 78 and 418 people with out of Alzheimer's disease whose age, gender and educational background matchedParticipants completed a food questionnaire five years ago, describing early on the type and frequency of food they ate during the year, from less than once a month to more than four times a dayGive them a health check every two to three yearsThe researchers compared data from the food questionnaire with the foods often eaten by people with dementia and those without dementiaresearchers found that while the amount of individual food people ate varied almost without difference, there was a large difference in the overall food group or food web between people with dementia and people without dementiaprocessed meat is a "hub" in the food web for people with dementia, and people with dementia are more likely to consume processed meats such as sausages, cured meats and starchy foods such as potatoes, alcohol and snacks like biscuits and cakes This may indicate that the frequency with which processed meats are combined with other unhealthy foods, rather than the average amount, may be important for dementia risk For example, people with dementia are more likely to eat processed meat with potatoes when they eat it, while people without dementia are more likely to eat meat with a variety of foods, including fruits, vegetables and seafood generally, people without dementia are more likely to eat varied diets, and many small food nets typically include healthier foods such as fruits and vegetables, seafood, poultry and meat Samiri said: "We found that dietary diversity and more healthy food intake were associated with reduced dementia, and in fact, in the years leading up to the diagnosis of dementia, the difference sain between the food networks was obvious Using food networks to study diets may help unlock the complexities of diet and health and disease biology one limitation of the study was that participants completed a food questionnaire that relied on their ability to accurately recall food, rather than having researchers monitor their diet Another limitation is to record a diet only once in the years before a dementia attack, so any changes in diet are unknown
