Have you already read The Sharp­Brains Guide to Brain Fit­ness?

Let’s see…

1. Pick the only part of your body that does not con­tain fat:

a. Arm
b. Thigh
c. Brain
d. None

Answer: d) Fats are also present in the brain: in neu­rons’ mem­branes to keep them flex­i­ble. These fats are the omega 3 and omega 6 fatty acids mol­e­cules. (Page 32 of the book)

2. Pick the only food prod­uct that doesn’t con­tain Omega-3 fatty acids

a. Tuna
b. Wal­nut
c. Kiwi
d. Jelly Beans

Answer: d) Fatty acids can be found in cold-water fish (such as mack­erel, her­ring, salmon, and tuna), kiwi, and wal­nuts. (Page 33)

3. Pick the only food prod­uct that doesn’t con­tain antioxidants

a. Olive oil
b. Milk
c. Nuts
d. Berries

Answer: b) Antiox­i­dants can be found in veg­etable oils, nuts, green leafy veg­eta­bles (e.g., spinach), cit­rus fruit, and berries. (Page 33)

4. Chronic Stress cannot:

a. Pre­vent you from being cre­ative
b. Kill brain cells
c. Pre­vent you from sleep­ing
d. Kill liver cells

Answer: d) Pro­longed expo­sure to adrenal steroid hor­mones like cor­ti­sol, which is released into the blood stream when we are stressed, can lead to cell death and block the for­ma­tion of new neu­rons. (Page 35)

5. What type of phys­i­cal exer­cise is the best for your brain health?

a. Weight lift­ing
b. Aer­o­bic exer­cises
c. Flex­i­bil­ity exer­cises Read the rest of this entry »

As the Brain Fit­ness indus­try con­tin­ues to gain momen­tum, and peo­ple explore all the incred­i­ble brain-training tools being devel­oped, we hope that enthu­si­asts don’t take their eye off the impor­tance of the phys­i­cal health of the brain and all the sys­tems it com­mu­ni­cates with. The brain is unique in that it houses our cog­ni­tive and emo­tional capac­i­ties in the form of the mind. It is a ‘cog­ni­tive’ organ that hungers for stim­u­la­tion from new expe­ri­ences and chal­lenges. Many brain fit­ness pro­grams strive to sat­isfy this need. Yet the brain is also a phys­i­cal organ that plays by many of the same rules as the heart, lungs, liver and kid­neys. To stay healthy and per­form opti­mally it requires qual­ity nutri­tion, phys­i­cal activ­ity and opti­mal sleep. The brain, espe­cially, relies on a healthy vas­cu­lar sys­tem to effi­ciently deliver oxy­gen and key nutri­ents and remove waste. In fact, the brain uses approx­i­mately 20% of the oxy­gen we breathe to sat­isfy its high-energy demands. Given that the brain only weighs about 2% of the body, we can con­sider it an energy hog and we must cater to its needs very carefully.

Nutri­ents play key roles in brain func­tion. Sev­eral have shown effi­cacy in clin­i­cal tri­als treat­ing cases of mood dis­or­ders, cog­ni­tive decline and of course ben­e­fit­ing the phys­i­cal health of the brain. Nutri­ents are both the raw mate­ri­als employed in cre­at­ing new neural con­nec­tions and Read the rest of this entry »

In other words, may some foods be specif­i­cally good for brain function?

For a great in-depth review of the effects of food on the brain you can check out Fer­nando Gomez-Pinilla’s recent arti­cle in Nature Reviews Neu­ro­science (ref­er­ence below). Here is an overview of the state off the research.

Sev­eral com­po­nents of diet seem to have a pos­i­tive effect on brain function.

Omega-3 fatty acids

These acids are nor­mal con­stituents of cell mem­branes and are essen­tial for nor­mal brain func­tion. Omega-3 fatty acids can be found in fish (salmon), kiwi, and wal­nuts. Docosa­hexaenoic acid, or DHA, is the most abun­dant omega-3 fatty acid in cell mem­branes in the brain. The human body pro­duces DHA but not enough. So we are depen­dent on the DHA that we get from what we eat.

A ran­dom­ized double-blind con­trolled trial (which means seri­ously con­ducted sci­en­tific study) is cur­rently look­ing at the effect of tak­ing omega-3 fatty acids on children’s per­for­mance at school in Eng­land. Pre­lim­i­nary results (Port­wood, 2006) sug­gest that Read the rest of this entry »
