Called the link between diet and dementia in question

The link between dietary patterns and dementia (advanced cognitive impairment) may never be clear, according to a new study published in the journal. Neurology.

Previous studies have shown that diet and other lifestyle actions may play a role in dementia risk, Especially in diabetic patients. Follow a vegetarian diet It has been linked to a lower risk of dementia, as has increased consumption of the basicAnd the AntioxidantsAnd the vegetable protein. Drink coffee or tea It has also been linked to a lower risk of dementia, while Eat inflammatory foods It has been linked to higher risks. When it comes to lifestyle actions other than diet, a Higher daily steps and body weight gain Both are associated with a lower risk of dementia, while poor oral health It is associated with an increased risk of dementia.

In the most recent study, researchers compared the eating habits of 28,025 middle-aged adults with their risk of developing dementia in the following years, with an average follow-up period of 19.8 years. All study participants were residents of Malmö, Sweden, born between 1923 and 1950, with a mean age of 58.1 at the start of the study (between 1991 and 1996). The participants’ dietary habits were assessed using a 7-day food diary, a detailed food frequency questionnaire, and a 1-hour interview. When comparing dietary patterns with the risk of dementia, the researchers adjusted for factors including participants’ age, gender, and other health conditions. smoking statusAnd the drinking alcoholAnd the Physical activity.

Dementia risk is not linked to dietary patterns

During the follow-up period, 1943 participants (6.9%) were diagnosed with dementia. The researchers found that participants whose eating patterns closely followed general dietary recommendations were no less likely to develop dementia. In fact, the participants with the worst adherence to dietary recommendations, compared to the best, were 7% less likely to develop dementia of all causes, and only 3% more likely to develop dementia. Alzheimer’s disease. When researchers looked at adherence to a modified formula Mediterranean dietno similar benefit was found – participants with the worst adherence were 7% less likely to develop dementia from all causes and 10% less likely to develop Alzheimer’s disease.

None of these results were large enough to be statistically significant — meaning they may have been due to chance, rather than what the participants actually ate. The results were similar when people who developed dementia within the first five years were excluded from the analysis, as well as when people with diabetes were excluded from the analysis.

There are some important limitations and caveats to this study. First, their diet was assessed for participants only initially, not throughout the follow-up period. It is possible that the participants’ dietary patterns may have changed, and that these changes could have contributed to a higher or lower risk of dementia. It’s also possible that the general dietary recommendations and the modified Mediterranean diet that the researchers included in their analysis aren’t the best dietary patterns for preventing dementia — but other dietary patterns can be of significant benefit when it comes to dementia risk.
