Too Much Sugar
Our bodies and our brains need sugar in order to function, but our modern diets include way too much of it. When you eat too much sugar on a regular basis, your cells, including brain cells, are in a state of chronic inflammation.
That impacts the ability of your body to absorb important nutrients from food and begins to starve the brain of what it needs for optimal cognition. Ultimately, you will have a higher risk of dementia and a smaller hippocampus, the region in the brain that manages memory.
