The balance of fats in our body is not only important for heart health or weight management—it also plays a crucial role in brain function. Recent research suggests that when the balance of body fat is disturbed, it may weaken brain nerves and increase the risk of neurological disorders such as Parkinson’s disease.
The brain is made up of nearly 60% fat, and these fats are essential for protecting nerve cells, supporting communication between neurons, and maintaining overall brain health. Healthy fats, especially omega-3 fatty acids, help build the protective layers around nerves and reduce inflammation. However, when unhealthy fats like trans fats and excess saturated fats dominate the body, they can trigger chronic inflammation.
This inflammation can damage the neurons responsible for movement and coordination. In Parkinson’s disease, the brain cells that produce dopamine—a chemical needed for smooth and controlled movement—gradually deteriorate. Studies suggest that poor fat balance may accelerate this damage, making the brain more vulnerable to neurodegenerative conditions.
Excess body fat, particularly around the abdomen, is also linked to insulin resistance and metabolic problems. These conditions reduce blood flow and nutrient supply to the brain, further weakening nerve cells. Over time, this may increase the risk of memory problems, slower thinking, and movement disorders.
Maintaining a healthy fat balance can help protect brain health. Including foods rich in good fats—such as nuts, seeds, fatty fish, olive oil, and avocados—can support nerve function. At the same time, reducing processed foods, fried items, and trans fats can lower inflammation and protect brain cells.
Regular physical activity, adequate sleep, and a balanced diet also play an important role in keeping body fat in check and supporting overall brain health.
In simple terms: when body fat becomes unhealthy or imbalanced, it can harm brain nerves. But with the right lifestyle choices, it is possible to protect both body and brain from long-term damage.
