High-fat Diet and Brain Aging: Using a mouse model of an accelerated aging condition called Cockayne syndrome, researchers found that a high fat (low carbohydrate) diet postponed the aging process in these animals. It remains to be seen if this approach has merit for people with this disease or other related conditions.
Could a high-fat diet help slow brain aging?

Folate and B12 in Aging: Vitamin B12 deficiency is known to cause neural damage and compromise brain function. A study of almost 3000 people age 65 and older (with high blood homocysteine levels) found that two years of supplementation with folate and vitamin B12 reduced homocysteine levels more than a placebo, but did not have any measurable benefit to scores on thinking and memory tests. This is not surprising in this study because the B12 status of study participants taking the placebo was the same as those taking the supplement.

Age-related Brain Decline and Mobility: Small areas of damage in the brain that are visible on magnetic resonance imaging (MRI) are common in older people. This type of brain damage has been linked to problems with basic movements such as walking. However, a new study found that older people who remained more physically active did not have a decline in their movement abilities even when they did have high levels of brain damage.So, keep moving!

Milk and Brain Health: Researchers used a high-tech brain scanning technique on older adults to measure brain levels of an antioxidant synthesized in the body (glutathione). They found that its concentrations were higher in those with greater consumption of milk products. They speculated that dairy foods may provide the brain with the precursors needed for glutathione synthesis. More research is needed to prove this.

Body Mass Index and Dementia: Surprising results from a study of almost two million people indicate that underweight people had a 39% greater risk of developing dementia compared with those with a normal healthy weight. The bigger surprise, overweight people had an 18% reduction in dementia and obese people had 24% less risk. Since overweight and obesity increase the risk for other diseases, the clearest message from this research is to maintain a healthy weight - not too high or too low.
Being overweight 'reduces dementia risk'

Omega-3 Fatty Acids and Brain Aging: Some research has found that those who consume more of the fish oil type long-chain omega-3 fatty acids maintain better brain function with aging. However, a new large well-designed placebo-controlled study found that supplementation with omega-3 fatty acids did not benefit cognitive function. One limitation of this study of people mostly in their mid-70s is that it followed people for 5 years and cannot predict the outcome over a longer period of time.

Nutrition and Dementia: Many life factors may contribute to the development of cognitive decline and dementia with aging. However, nutrition plays a much greater role in maintaining brain health than often is appreciated. For example, vitamin B12 deficiency, common in older people, can cause symptoms virtually identical to early Alzheimer's disease. Meeting many other essential nutrient needs throughout life is important for ongoing brain health.

Eating Time and Mental Function: There is evidence that eating during our usual sleeping time of the day can affect physiological and biochemical functions involved in learning and memory. An innovative mouse study found that feeding mice only during their usual sleeping time of day altered function in specific parts of the brain in ways that adversely affected learning and memory.

B12 Deficiency in Elderly: Based on blood levels of vitamin B12, Canadian researchers found that almost 14 per cent of elderly adults entering long-term care facilities were deficient in the vitamin. This is likely an underestimate of the incidence because there are better tests for vitamin B12 status assessment (methylmalonic acid levels). B12 malabsorption is common at this stage of life and the form of vitamin B12 in natural food sources is very poorly absorbed. Consequently, B12 injections or high dose supplementation is needed to return B12 status to normal.

Diabetes and Brain: Over time, diabetes is known to have negative effects on brain function. A 10-year study was conducted on people with diabetes (45 to 76 years of age). It was found that those who lost weight and exercised by participating in an intensive lifestyle intervention program had less measurable impact on changes in brain structure than those in a less rigorous educational program. Additional research is needed to see if this translates into less cognitive decline.

Vitamin D and ADHD: At two and a half years of age, children were less likely to be diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) if their mothers took vitamin D supplements during pregnancy and had good vitamin D status when the child was born. Another study found a similar association between iron supplementation during pregnancy and reduced risk of having an autistic child. Iron deficiency can lower measures of vitamin D status, so each of these nutrients may complement the other. Meeting all nutrient needs during pregnancy is likely the most important take-home message.

Dietary Cholesterol and Dementia: With the relatively recent awareness that dietary cholesterol has little effect on blood cholesterol levels, it is widely accepted that dietary cholesterol does not significantly increase the risk of cardiovascular disease. In addition, a new study conducted in Finland found that neither cholesterol nor egg intake was associated with the risk of dementia or Alzheimer's Disease. Instead, moderate egg intake appeared to have a beneficial association with certain types of cognitive performance.

Iron Deficiency and Mental Performance: A study conducted with about 100 female college students, age 18-35 years, analyzed the association of iron status and fitness level with GPA. They found that the GPA was significantly greater in women with good iron status (ferritin at least 20 mcg/L). Although higher level fitness was associated with better GPAs, those who had a high level of fitness, but were iron deficient, tended to have lower GPAs than unfit women who had good iron status.

Insulin Resistance and Mental Decline: With older age and sedentary lifestyle, many cells in the body can become less sensitive to insulin. This requires the pancreas to produce more insulin to promote the uptake of glucose from the blood into cells. New research reports that those who develop insulin resistance with age are more likely to experience mental decline. This is another good reason to stay physically active and maintain a healthy body weight with age.
Insulin resistance may lead to faster cognitive decline

This abnormal protein folding is similar to what is observed in some age-related brain diseases in humans. Understanding this process in yeast cells may lead to research in human cells to see if zinc is involved in brain disease.

Protein Deficiency and Brain Function: A detailed study on protein deficiency (using a rat model) found that protein deficiency not only impaired growth, but brain function as well. A chronic protein deficiency impaired learning, memory and cognitive function. The results of the study, conducted by researchers in India, supported observations of the impact of protein deficiency on malnourished children in India.

DHA and Brain Health: The omega-3 fatty acid docosahexaenoic acid (DHA) is a major component of brain tissues. A study of patients with mild Alzheimer's disease found that taking a supplement high in DHA for six months raised levels of DHA in the cerebral spinal fluid. This indicated increased DHA levels in the brain. There also were indications that disease progression was slowed.

Lithium and Alzheimer's Disease: Lithium is an element that generally is not considered to be an essential nutrient. However, it has long been used as a drug for treatment of various psychological conditions. Recently, researchers found that delivery of very small amounts of lithium into the blood via rectal suppositories prevented and reversed brain and behavior changes normally seen in a transgenic rat model for Alzheimer's disease. Human clinical studies are being planned.

Choline to Prevent Schizophrenia: The essential nutrient choline appears to be especially important for fetal brain development. Choline supplements taken by pregnant women during the second and third trimesters of pregnancy enhanced normal brain functions associated with a reduced risk of developing schizophrenia. Eggs are the richest common food source of choline,

Iron and Cognitive Development: It has been known for a long time that adequate dietary iron is essential for normal early brain development. A new study extends this relationship throughout adolescence and into young adulthood. Lower brain iron, especially in the putamen subregion, was correlated with impaired performance especially on tasks involving reasoning and spatial processing.

Low Blood Pressure and Brain Shrinkage: Although high blood pressure receives much more attention than low blood pressure, studies have shown that both high and low blood pressure are associated with brain shrinkage with age. In particular, studies in older people have shown a relation between low blood pressure and more brain loss.
