Brain Quiz: Do You Have a Brain?

September 7, 2009 by Dr. Pascale Michelon

Have you already read The Sharp­Brains Guide to Brain Fit­ness?

Let’s see…brain health and brain fitness

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 more…] about Brain Quiz: Do You Have a Brain?

A User’s Guide to Lifelong Brain Health: BrainFit for Life

October 14, 2008 by Dr. Simon Evans

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 more…] about A User’s Guide to Life­long Brain Health: Brain­Fit for Life

Can food improve brain health?

September 8, 2008 by Dr. Pascale Michelon

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 more…] about Can food improve brain health?
