For improving impaired memory and mental function, good nutrition is the key.
Are memory loss and decreased brain power inevitable as we age? Many people in their 40s, 50s, and beyond are told that they are and that there’s nothing that can be done about it. Is that true? Of course not! That’s where good nutrition comes into play.
Brain cells are the most complex, long-living, and nutritionally demanding cells in the body. Studies have shown that intelligence, memory, behavior, and concentration are all influenced by nutrition. Young or old, our nutritional status plays a vital role in determining how well our brain functions.
Super Nutrition to Feed Your Brain
A key goal for brain health is to bathe the brain in “super nutrition.” Simply put, high nutritional status equals higher mental function. Given the frequency of nutrient deficiency in seniors, it is likely that many cases of impaired mental function may have a nutritional cause.
A study conducted at Oxford’s Department of Clinical Neurosciences involved 156 elderly patients who had mild cognitive impairment and a high risk of dementia and Alzheimer’s disease. The patients were divided into two groups: one group took a daily supplement containing 800 mcg of folic acid, 20 mg of vitamin B6, and 500 mcg of vitamin B12; the other group took a placebo.
Before and during the testing period, researchers used magnetic resonance imaging (MRI) to measure the atrophy levels of grey matter in the patients’ brains. Atrophying (shrinking) grey matter is a sign of the progression of Alzheimer’s and other forms of dementia. Upon completion of the two-year study, researchers found that those given the supplement had about seven times less atrophy than the placebo group.
The study also found that those whose grey matter shrunk fastest had higher levels of homocysteine, and those with higher homocysteine levels initially received the greatest benefit from supplementation. In their conclusion, the researchers stated: “Our results show that B-vitamin supplementation can slow the atrophy of specific brain regions that are a key component of the Alzheimer’s disease process and that are associated with cognitive decline.”
In addition to taking a high potency multiple vitamin and mineral formula to supply the brain with super nutrition, it makes sense to add 1,000-3,000 mg of EPA and DHA (combined) from a high-quality fish oil formula. Higher intakes of omega-3 fatty acids are associated with higher mood and mental function scores.
If symptoms of mental deterioration are definitely present in a person 50 years of age or older, consider phosphatidylserine (PS), which plays a major role in determining the integrity and fluidity of brain cell membranes. Over a dozen double-blind studies have shown that PS can help improve mental function, mood, and behavior in patients with degenerative brain disorders. Try 100 mg three times daily.
The Best Brain Foods
The key dietary factors that reduce the risk of dementia and Alzheimer’s disease from population-based studies are higher fish consumption (and higher intake of omega-3 fats), monounsaturated fatty acids (primarily from olive oil), light to moderate alcohol use (primarily red wine), and increased non-starchy vegetable and fruit consumption. It is likely that a combination of all of these factors will provide the highest degree of protection.
Blueberries or blueberry extracts are particularly helpful, according to one study. When older rats were given the human equivalent of 1 cup of blueberries per day, they demonstrated significant improvements in learning and motor skills, making them mentally equivalent to younger rats. When the rats’ brains were examined, the brain cells of those given blueberries were found to communicate more effectively than those of rats not given blueberries. An alternative to eating more blueberries is taking a flavonoid-rich extract such as grape seed or pine bark extract (100-300 mg daily).
Celery and celery seed extracts contain a compound, 3-n-butylphthalide (3nB), that has brain-health benefits. In human and animal studies, 3nB significantly improved learning deficits, as well as long-term spatial memory. Researchers have concluded that “3nB shows promising preclinical potential as a multi-target drug for the prevention and/or treatment of Alzheimer’s disease.”
Ginkgo biloba extract is a popular herbal approach to boosting brain power. Use 60–120 mg of standardized extract (i.e., 24-percent ginkgo flavonglycoside extract), one to two times daily. Do not take ginkgo with blood-thinning drugs.
Traditionally used to enhance memory, learning, and concentration in Ayurvedic medicine, bacopa is another popular herbal brain booster. Emerging clinical evidence is validating its benefits. In one study, 46 healthy volunteers (ages 18-60) were divided into treatment and placebo groups. Participants were given 300 mg daily of a bacopa extract. At the end of the 12-week study, there was a significant improvement in verbal learning, memory, and information processing in the bacopa group compared to a placebo.
