La dieta MIND può aiutare a mantenere il nostro cervello sano?

What is the MIND diet?

The MIND diet is a combination of the dieta DASH e lDieta mediterranea, with a focus on foods that can boost brain health.

US nutritionist Dr Martha Clare Morris developed MIND - Mediterranean-DASH Intervention for Neurodegenerative Delay - to see how what we eat can lower the chance of dementia and to stop our brain power declining as we get older.

Il Dieta mediterranea focuses on eating foods that are as natural as possible, while limiting unhealthy fats and red meat. The DASH diet is designed to prevent or lower ipertensione and encourages people to eat healthy foods that contain less salt.

In 2015, Morris and her team published a study that found that people who followed the Mediterranean and DASH diets had better levels of brain function compared to people who didn’t follow those diets. The study also found that eating whole grains, leafy greens, nuts, and berries were also associated with better brain health¹.

Sophie Medlin, director and specialist dietitian at City Dietitians and chair of the British Dietetic Association (BDA) for London, says the MIND diet encourages you to eat foods that contain nutrients that protect the brain and make it function at its best.

“Fish oils are particularly important for preserving the structure of the brain and berries are shown to improve brain function, including memory and focus,” adds Medlin.

These foods contain high levels of health-giving antioxidants which protect the cells of the body from DNA damage and ridurre l'infiammazione. Oxidative stress can cause damage to organs and contributes to diseases such as demenza, cancro e malattie cardiache.

The MIND diet foods contain nutrients such as vitamin C, Omega 3, B vitamins, magnesium, zinc, and iron, which all contribute to overall brain function.

The MIND diet encourages you to limit your consumption of these foods:

• Pastries and sweets.

• Red meat.

• Cheese.

• Fried foods.

• Butter and margarine.

These foods are processed or contain a lot of sugar, which can be harmful to our brain function.

Medlin explains that the MIND diet has been well-researched and there is huge credibility behind its potential to reduce brain health decline.

She says: “The 2015 study found that the higher the MIND diet score, the slower the rate of brain health decline in comparison to those with a low MIND diet score.”

In this study, Morris and her team conducted studies of the MIND diet for nearly a decade, working with a group of 923 participants. The results showed that people who stuck rigidly to the diet had a 53% lower chance of Malattia di Alzheimer - and those who followed the diet moderately well had a 35% lower chance. The longer a person followed the diet, the better protected they were from developing the condition.

Other studies have linked the MIND diet to a slower rate of brain health decline after stroke, better verbal memory in later life and larger total brain volume. However, more research is needed over a longer period to see how the MIND diet may affect people long-term.

Unlike many other diets, the MIND diet doesn’t include meal plans so you have to make your own recipes based on the foods included. You aren’t restricted to only eating these foods, too. Although this means the plan is more flexible, it may be challenging for people who don’t cook.
