Why the Mediterranean Diet is Good for Your Brain

Why the Mediterranean Diet is Good for Your Brain

The human brain is amazing. It has 100 billion neurons, aka nerve cells, and it consumes 20% of the body’s total energy, which is significant given its size.1 In order for the brain to keep firing on all cylinders, it requires the right fuel to function properly. And that fuel comes from food. According to a recent study, the type of fuel you feed your brain can make a significant difference.

Reviewing the Research

The study was published in 2023 in the journal BMC Medicine and featured information from more than 60,000 people in the United Kingdom.2 The researchers found that the people who ate a Mediterranean Diet had better brain function than the people who did not eat a Mediterranean Diet. This is consistent with previous research also showing that the Mediterranean Diet may help support brain function.3

Why is the Mediterranean Diet Good for the Brain?

One of the reasons the Mediterranean Diet is so good for the brain is because it emphasizes healthy fats, specifically extra-virgin olive oil, which have been shown to benefit brain health.4 The diet also includes nuts and fish, which are great sources of healthy fats.

What is the Mediterranean Diet?

In a nutshell, the Mediterranean Diet is a plant-based, whole foods diet that focuses on green leafy vegetables, nuts, fresh fruits, whole grains, and olive oil.5 Animal protein is eaten in smaller quantities and fish is the preferred protein source. If red meat is eaten, it’s more of a side dish versus a main part of the meal.

Here are some additional characteristics of the Mediterranean style of eating:6

  • Each meal includes colorful fruits and vegetables.

  • There is less salt and more herbs, spices, garlic, and onions.

  • There is an emphasis on fresh locally grown foods.

  • Processed foods are reduced or avoided completely.

Fuel Your Brain

The human brain is very active. Like a sponge, your body soaks up valuable nutrients and uses food as fuel to keep it functioning at peak capacity. And, as research shows, the Mediterranean Diet is a great way to fuel the brain.
