Dr. Curtis Cripe: The Best Diet to Keep Your Brain Healthy

There are more centenarians in the U.S. now than there were 20 years ago. The numbers are still relatively small, but they're definitely on an upward trajectory. Americans are becoming increasingly aware of disease risk factors, such as smoking.

The prevalence of dementia is declining among Americans as well, says Dr. Curtis Cripe. And for the same reason—education. Awareness encourages people to protect their health.

One of the most notable features of our brain is its consumption of energy. Although it only accounts for 2% of body weight, the brain is so metabolically active that it burns 20% of the body's fuel.

Evidence suggests that cognitive decline, including Alzheimer's disease, may be a metabolic disorder. It may be caused by a disturbance in fuel operations by the brain. This process is inherently influenced by what we eat. Researchers found that the earliest changes caused by Alzheimer's disease are those affecting glucose—the brain's primary fuel.

It likely explains why studies link the Mediterranean diet to protection against dementia. Studies have consistently associated the Mediterranean diet with reduced rates of Alzheimer's disease, lower rates of brain atrophy, and improved cognitive function. Compared to the standard Western diet, the Mediterranean diet includes less meat, especially less red and processed meat, in favor of fish. It also features fewer simple carbohydrates, higher amounts of monounsaturated fats, notably olive oil, and more plant-based foods, not only fresh fruits and vegetables but whole grains and nuts.

The shift to plant-based foods ensures that a consistent supply of agents is available to reduce free radicals, stimulate the removal of damaged biomolecules, and maintain brain function. Fruits and vegetables are naturally rich in substances that act as antioxidants, adds Dr. Curtis Cripe. Several studies found that antioxidants may reverse some of the symptoms of aging.

Dr. Curtis Cripe's professional and academic background spans several disciplines, including engineering, software development, psychology (health psychology and behavioral medicine), and bioengineering. He currently heads the research and development department at NTL Group. For similar blogs and articles, bookmark this link.
