Chances are you have already heard of omegas, especially if you are health conscious or have read previous posts on this blog. The mighty essential fatty acids omega 3 and 6 are power houses of energy and also have a fantastic range of health benefits which covers the whole body (from head to toe).

Nutrient levels linked to brain health

I recently wrote about the reported benefits of the nutrient choline for improved memory and brain health. A new study, soon to be published in the journal Neurology, has now investigated the link between brain health and other nutrients in the diet, including Vitamins B, C, D and E, omega 3 and trans fats.

Choline: The Brain Food

A new study conducted at the Boston University School of Medicine suggests that the nutrient choline may improve cognitive function in healthy adults.

Choline is a precursor to the neurotransmitter acetylcholine, which plays a part in memory and other cognitive functions. Low acetylcholine levels are linked with Alzheimer’s.

A group of 1391 healthy (dementia-free) [...]

More evidence points toward the importance of vitamin B12 to protect against Alzheimer’s disease

In November  I mentioned a study which found that supplemental B vitamins which lowered homocysteine levels in the body might be useful to help elderly individuals with mild cognitive [mental function] impairment.  A recent study (1) has found that Vitamin B12 may help protect against Alzheimer’s disease.  The results of the research suggests that elderly individuals [...]

Study finds association between vitamin D levels and cognition

Low levels of vitamin D  in the blood have been linked to poorer mood and reduced brain function, or cognition.  Lack of the sunshine vitamin has also been implicated in Seasonal Affective Disorder (SAD)

Research in the areas of vitamin D and brain function is still building and the relationship is still not clear.  [...]

Brain function may be protected by walking

A study (1) has found that walking at least six miles (cumulatively) a week may help protect elderly individuals from age-related ‘brain shrinkage’ (loss of brain grey matter).  In May last year I wrote about a study which found that walking might help protect women against strokes and I have previously written about the importance [...]

A plant rich diet is associated with better brain function

A healthy diet rich in fruit and vegetables has been previously linked to the prevention of many chronic diseases from heart disease to cancer and Alzheimer’s disease.  A study published in the British Journal of Nutrition (1) has found that “In the elderly, a diet rich in plant foods is associated with better performance [...]

DHA supplementation may protect the ageing brain

 Docosahexaenoic acid, or DHA, is a long chain omega 3 fatty acid naturally found in oily fish such as mackerel, trout, sardines and salmon.  The brain contains a high proportion of DHA and, as you will see from my past blog posts, omega 3 fats have been linked to brain benefits including protection from depression and [...]

B Vitamins may be important for people with memory problems

In older individuals, especially those who are suffering from cognitive (brain function) decline, there is often an increased rate of brain wastage/shrinking (atrophy).  Previous studies have found that homocysteine is a risk factor for brain atrophy, cognitive impairment and dementia.  It is also known that blood plasma concentrations of homocysteine can be lowered by [...]

Study finds that blueberry juice may improve memory in older adults

Previously I have investigated how healthy lifestyle and diet can impact brain function and have also looked at the importance of vegetables and fruits for a well working brain.  A very recently published preliminary small study (1) has found that blueberries may be particularly useful to memory.

The authors of the study wrote in their [...]
