Brain Foods: Foods That Make You Smarter

Updated on August 28, 2013

There are certain foods that make our brain healthy.There is this evidence that oily fish is considered as brain food besides turmeric and some fruits and vegetables.

Have you heard of the word “omega-3 fatty acids?” Omega - 3 fatty acids are not only good for the brain but also good for the heart. DHA (docosahexaenoic acid), the main constituent of the cell membranes in the brain is one of the omega-3s. And a deficiency on it can weaken brain’s architecture and leave it vulnerable to disease.

Brain foods that make you smarter

Oily fish like herring, salmon, sardines, black cod, mackerel and bluefish are the best source of omega-3 fatty acids.

Vegetarian sources of omega-3s are hemp, flax and walnuts. They are good additions to the diet but are not as reliable as fish.

Some people rely on fish-oil-supplements. Some supplements are flavored and some even taste good. A good starting dose of fish oil of any kind is 1 g a day. Higher doses which are up to 10 g a day is for the treatment of diverse conditions such as depression, autism, bipolar disorder, and attention-deficit disorder, with varying results.

For vegetarians and vegans, there is non-fish source of omega-3s – supplements made from algae. Algae are the source of omega 3s that fish store in their fat.

Turmeric, another source of omega-3s, a relative of ginger, is a yellow spice which is the main ingredient in American mustard and Indian curries. It is a powerful inflammatory agent and may offer protection against Alzheimer’s disease. Alzheimer’s begins as an inflammatory process in the brain. Scientists have now carefully studied other medicinal effects of turmeric.

A study shows that India has the world’s lowest rate of Alzheimer’s. The contributing factor might be their daily consumption of turmeric.

Brightly colored fruits and vegetables, another source of omega-3s, have anti-oxidant properties. It offers protection against cancer and other chronic diseases like Parkinson’s disease.

Brain foods I mentioned above should be supplemented with vitamins, exercise and healthy lifestyle.

    Non-vegans have the advantage over the vegans because we could consume any DHA food sources; vegans don’t since they don’t consume any fish. So, vegans rely only on the ALA form. ALA is important in nutrition and still beneficial to vegans because it is an essential acid. The least part of the benefit is the limited conversion of ALA to DHA.

    BlissfulWriter, thanks for the input. Your comment is much appreciated.

    Yes, I love getting my omega-3 fats. But I prefer getting the DHA form of the omega-3 (such as in salmon) rather than the ALA form which is in flax and walnuts. It is the DHA that is especially beneficial to the brain. Although the body can convert ALA to DHA, the process is limited.

    I totally agree, also I think diabetes can be a problem for some and too much glucose in that instance would be extremely dangerous

    Supercellbaebe - Thanks for your input.

    Anyone who plans to incorporate glucose into their diet must check with the doctor first for the right amount of dosage since high amount of it can impair cognitive functions.
