Although research linking diet and dementia is still in its infancy, there are a few important relationships between nutrients and brain health that are worth exploring. Having a nourishing, well rounded diet gives our brain the best chance of avoiding disease. If your diet is unbalanced for whatever reason, you may want to consider a multivitamin and mineral complex and an omega-3 fatty acid supplement to help make up a few of the essentials. If you are considering taking a supplement it is best to discuss this with a doctor or qualified healthcare professional. Go nuts A study published in the American Journal of Epidemiology suggests that a good intake of vitamin E might help to prevent cognitive decline, particularly in the elderly. Nuts are a great source of vitamin E along with leafy green vegetables, asparagus, olives, seeds, eggs, brown rice and wholegrains. Broccoli A great source of vitamin K, which is known to enhance cognitive function and improve brainpower. Pumpkin seeds Just a handful of pumpkin seeds a day is all you need to get your recommended daily amount of zinc, vital for enhancing memory and thinking skills. Blackberry Vitamin C has long been thought to have the power to increase mental agility. One of the best sources of this vital vitamin are blackberry. Eat more tomatoes There is good evidence to suggest that lycopene, a powerful antioxidant found in tomatoes, could help protect against the kind of free radical damage to cells which occurs in the development of dementia, particularly Alzheimer's. Binge on blueberries Evidence accumulated at Tufts University in the United States suggests that the consumption of blueberries may be effective in improving or delaying short term memory loss. Widely available, so there's no excuse. wholegrains Like everything else in your body, the brain cannot work without energy. The ability to concentrate and focus comes from the adequate, steady supply of energy - in the form of glucose in our blood to the brain. Achieve this by choosing wholegrains with a low-GI, which release glucose slowly into the bloodstream, keeping you mentally alert throughout the day.
