The Mediterranean Diet May Not Lower Dementia Risk, Study Says

By Ghuman

Introduction

The Mediterranean diet has long been touted as a healthy way to eat, with many studies showing its potential to reduce the risk of heart disease, stroke, and other chronic illnesses. However, a new study suggests that the Mediterranean diet may not be as effective in reducing the risk of dementia as previously thought. The study, which was published in the journal Neurology, found that following a Mediterranean diet did not lower the risk of developing dementia compared to those who did not follow the diet. The findings suggest that other lifestyle factors, such as physical activity and social engagement, may be more important in reducing the risk of dementia.

The Mediterranean Diet May Not Lower Dementia Risk, Study Says

A new study has found that the Mediterranean diet may not be as effective as previously thought in lowering the risk of dementia. The study, published in the journal Neurology, looked at the diets of more than 4,000 people over the age of 65 in Spain. The researchers found that while those who followed the Mediterranean diet had a lower risk of developing dementia, the difference was not statistically significant.

The Mediterranean diet is a traditional dietary pattern that is based on the traditional diets of countries bordering the Mediterranean Sea. It is high in fruits, vegetables, whole grains, legumes, nuts, and olive oil, and low in red meat, processed foods, and sugar. It has been linked to a number of health benefits, including a lower risk of heart disease, stroke, and some types of cancer.

The study looked at the diets of 4,078 people over the age of 65 in Spain. The participants were followed for an average of 4.5 years. During that time, the researchers found that those who followed the Mediterranean diet had a lower risk of developing dementia, but the difference was not statistically significant.

The researchers concluded that while the Mediterranean diet may have some benefits, it may not be as effective as previously thought in lowering the risk of dementia. They suggest that further research is needed to better understand the potential benefits of the diet.

What you eat can affect how your brain functions and how quickly it ages. That includes potentially avoiding cognitive issues like dementia, which is something that affects millions of people, according to the CDC. That’s why you want to make sure you’re regularly consuming foods that will benefit your brain. With that in mind, you’ll surely be interested to learn that a recent study found that a certain popular diet may not actually reduce the risk of dementia.

This study by researchers from Lund University in Sweden was published in Neurology and involved 28,025 participants who were an average age of 58.1 years old. At the beginning of the study, the participants were also free of dementia. Over the course of 20 years, those involved were asked to answer a questionnaire and interview questions, as well as log their eating habits. The researchers specifically took a look at whether or not the participants’ diets fulfilled the requirements of the Mediterranean diet.

The researchers also noted that at the end of the 20-year period, 6.9% (or 1,943) of the participants had been diagnosed with dementia. Both Alzheimer’s disease and vascular dementia were among the diagnoses.

When the researchers compared the participants’ diets to the diagnoses and factored in various aspects such as age, gender, and education levels, they failed to find a connection between eating the Mediterranean diet and a reduced risk of dementia.

What experts say about these findings

“While our study does not rule out a possible association between diet and dementia, we did not find a link in our study, which had a long follow-up period, included younger participants than some other studies, and did not require people to remember what foods they had eaten regularly years before,” study author Dr. Isabelle Glans, research and doctoral student at Lund University, said in a press release.

“One strength of this study is that it had participants record what they ate instead of trying to remember. It is difficult to recall what you ate in the past, especially serving size, and we may naturally recall the healthier foods we ate more than the ‘junk’ food,” Leann Poston M.D., M.B.A., M.Ed. of TeleMDNow, tells Eat This, Not That!

Poston also points out that “researchers followed participants for 20 years and looked for links between diet and dementia,” however, “none were found.” She adds, “To me, this is not surprising because most diets provide the baseline nutrients needed for brain metabolism. Choose whole-food diets that are high in fruits and vegetables, healthy sources of fat and protein, and rich in complex carbohydrates. Avoid highly processed foods.”

At the same time, Poston notes that “it is important not to discount the benefits of the Mediterranean diet, as it has cardiovascular benefits and may reduce the risk of obesity.” It’s also crucial to look at this study as just one study, and to make sure you’re getting as full a picture as possible.

A recent 2021 report published in Journal of Internal Medicine found that the Mediterranean diet is not only associated with a lower risk of cardiovascular disease, but was also found to be linked to lower incidences of age-related cognitive decline and neurodegenerative disorders.

Poston also brings up the fact that despite the mixed research on this topic, “High blood pressure, cardiovascular disease, type 2 diabetes, and obesity are chronic diseases affected by diet that may also increase your risk of dementia.”
