Mediterranean Diet Boosts Ageing Brain


A Mediterranean diet with added extra virgin olive oil or mixed nuts seems to improve the brain power of older people better than advising them to follow a low-fat diet, indicates research published online in the Journal of Neurology Neurosurgery and Psychiatry.

The authors from the University of Navarra in Spain base their findings on 522 men and women aged between 55 and 80 without cardiovascular disease but at high vascular risk because of underlying disease/conditions.

These included either type 2 diabetes or three of the following: high blood pressure; an unfavourable blood fat profile; overweight; a family history of early cardiovascular disease; and being a smoker.

Participants, who were all taking part in the PREDIMED trial looking at how best to ward off cardiovascular disease, were randomly allocated to a Mediterranean diet with added olive oil or mixed nuts or a control group receiving advice to follow the low-fat diet typically recommended to prevent heart attack and stroke

A Mediterranean diet is characterised by the use of virgin olive oil as the main culinary fat; high consumption of fruits, nuts, vegetables and pulses; moderate to high consumption of fish and seafood; low consumption of dairy products and red meat; and moderate intake of red wine.

Participants had regular check-ups with their family doctor and quarterly checks on their compliance with their prescribed diet.

After an average of 6.5 years, they were tested for signs of cognitive decline using a Mini Mental State Exam and a clock drawing test, which assess higher brain functions, including orientation, memory, language, visuospatial and visuoconstrution abilities and executive functions such as working memory, attention span, and abstract thinking.

At the end of the study period, 60 participants had developed mild cognitive impairment: 18 on the olive oil supplemented Mediterranean diet; 19 on the diet with added mixed nuts; and 23 on the control group.

A further 35 people developed dementia: 12 on the added olive oil diet; six on the added nut diet; and 17 on the low fat diet.

The average scores on both tests were significantly higher for those following either of the Mediterranean diets compared with those on the low fat option.

These findings held true irrespective of other influential factors, including age, family history of cognitive impairment or dementia, the presence of ApoE protein--associated with Alzheimers disease--educational attainment, exercise levels, vascular risk factors; energy intake and depression.

The authors acknowledge that their sample size was relatively small, and that because the study involved a group at high vascular risk, it doesnt necessarily follow that their findings are applicable to the general population.

But they say, theirs is the first long term trial to look at the impact of the Mediterranean diet on brain power, and that it adds to the increasing body of evidence suggesting that a high quality dietary pattern seems to protect cognitive function in the ageing brain.

Night Sleep Affect Childrens Brain Growth

Night Sleep Affect Childrens Brain Growth | Childs body has never stopped growing, even while they sleep, especially in the golden years of age (12 months to three years).

Generally, the long nights sleep is also a major effect on brain development in children, because the sleep remains be a priority for children.

Children need plenty of rest, because the growth and child development is very dependent of the bed, Without enough sleep, the child will not grow optimally, because here is happening repair brain cells, and approximately 80 percent of the growth hormone produced.

Parents should be smart to savor the moments that are important for brain child growth, one of which is when your baby sleep at night. Abnormalities in the brain also can be known of how the childs sleep patterns and sleep disorders will lead to the opposite effect.

all things that occur during sleep are a reflection of the activity of certain neurons in the central nervous system, which changes dramatically according to child development.

Therefore, sleep is related to child development, and has a connection to the childs cognitive functioning. The study, conducted the University of Minnesota and University of Montreal found that sleeping at night and naps are managed by different parts of the brain, in terms of circuitry and circadian rhythms.

Thus, time to sleep at night for a child can not be replaced with sleep in the day. The brain child growth also needs proper nutrition, because the brain needs energy to grow.
