Whole grains are an essential component of a diet that aims to enhance brain function and longevity. Unlike their refined counterparts, whole grains are rich in fiber, which helps to regulate the release of glucose into the bloodstream. This steady supply of glucose is crucial for the brain, as it is the organ’s primary source of fuel. Consuming
foods like barley, brown rice, buckwheat, and whole wheat ensures that your brain receives a consistent flow of energy, preventing spikes and crashes in blood sugar that can impair cognitive function.
