Cognitive Function Summary
Diet and nutrient intake has a major effect on cognitive performance and decline. Omega-3s, the fatty acids that make up the brain, are important for cognitive function, but omega-3 deficiency is common in the Western diet. B-vitamins are important in brain health as are anti-inflammatory nutrients. Foods like dark chocolate and blueberries are particularly rich in nutrients that reduce brain inflammation. Another nutrient, choline, is converted to acetylcholine- the brain neurotransmitter- but many people don't get enough choline. Choline supplements like Alpha GPC supply choline in a form more easily used by the brain. It is especially effective in combination with racetams, safe cognitive enhancers. One of the most effective, pramiracetam, increases the uptake and use of choline in the brain resulting in more acetylcholine being made.

Herbs and energy promoting nutrients can, also, improve cognitive function. Medium-chain triglycerides (MCT) are an alternate energy source to glucose that don't deposit as fat. MCT oil is derived from coconut and can improve memory and increase omega-3 in the brain. The capacity of herbs to enhance cognitive function is, perhaps, even more profound. Panax Ginseng, Bacopa Monnieri, Turmeric and several other herbs have been shown to increase cognitive function and prevent cognitive degeneration. In combinations these herbs can be particularly effective and many provide additional health benefits from reducing inflammation to aiding digestion.

Other Important Information
Two amino acids that may help cognition are Acetyl L-Carnitine and L-Glutamin hydrochloride. Animal proteins contain both L-Carnitine and L-Glutamin. Red meat has a lot of L-carnitine and plant based protein sources have L-Glutamin as well. Acetyl L-Carnitine supplements may be helpful for vegetarians.

Moderate red wine consumption may benefit cognitive function mainly due to its antioxidants and its resveratrol content.

Although not a food, rosemary oil fragrance may enhance cognition and improve mood. This essential oil can be used with a diffuser.

Another surprising way to preserve and promote cognitive function is through intermittent fasting- condensing your window of food consumption. There are several books on the topic of intermittent fasting to help you get started.
