Dementia associated with combining certain foods

French scientists have found that for the prevention of dementia may be important not only to the consumption of certain foods, but their combination among themselves. To do this, they examined in detail the eating habits of 208 people diagnosed with dementia several years before resolution of the diagnosis and compared them with the nutrition 418 people in the control group. Study participants who subsequently were diagnosed with dementia, were less diverse in your food and processed meat combined with bread, potatoes and soup, not fresh vegetables, as a control group. Article published in the journal Neurology.

Food is one of the most important components of a long and healthy life, and it concerns not only physical health but also brain function. So, for example, fans of walnut less likely to diagnose depression (it is believed that all the matter in the abundance of essential alpha-linolenic acid) and cognitive function of mice can be affected due to excess diet salt.

Many of these studies, however, concentrated on the study of harm or benefit individual products — be it salty, sweet, processed, dairy or flour, but seldom on the combination of any products with each other (at least, outside of common diets and food systems). To consider the popular combinations of products and their contribution to the possible development of dementia decided by scientists under the leadership of Cecilia Salieri (Cécilia Samieri) from the University of Bordeaux.

The researchers used data from a population-based study of elderly French people aged 65 years: in the beginning of the study participants (there were a total of 1522 people) spoke in detail about their dietary habits and health, and then updated the information during repeat visits for at least another five years. From 1522 people were followed for an average of 12 years, dementia was diagnosed in 215. Each participant with dementia, the scientists selected by the two control participant of the same sex, age (at start of study), level of education, and in the fact what time the first survey.

All participants interviewed in detail about what foods and how often they eat and what about consist of Breakfast, lunch and dinner. In particular, scholars interested in how the participants combine food and drinks from 10 groups: cereals, vegetables, fruits, meat products, seafood, sausages, fatty and sweet foods (include fast food), oils for cooking, dairy products and alcohol. Of these ten groups, scientists have identified 40 categories, and all participants were asked to tell about the consumption of 148 food and drinks.

On the basis of dietary habits of patients with dementia and control group participants, the researchers built a nutrition graphs, which showed how often the participants consumed products from one group or another, and how often these products are used in the same dishes.
