Brain Quiz: Do You Have a Brain?

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 the rest of this entry »

Can food improve brain health?

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 »
