Will that heavily-advertised ‘brain food’ help your child become smarter? Will all those DHA-fortified baby cereals and milks with ‘brain activators’ really help your daughter or son get better marks?

OK - I am no expert either on nutrition or brain development. But common sense counts still, and I remind you there is no substitute for a good diet and good teaching and studying. These will help your child, DHA or no DHA.

Two reasons for this:

1) It’s difficult for lay people like us to make sense of all the health-related news we get from the media. DHA may be good for your brain, but will DHA pills and DHA-fortified foods make you smarter? None of the manufacturers and marketers will tell you, but the pills and supplements are not proven yet, and we really don’t know yet what effect for good or bad they will have.

To take an example, while the body’s own testosterone boosts sperm production, fertility doctors only recently found that synthetic testosterone can make men infertile. Synthetic testosterone is still taken by athletes and body builders for more energy, and by men who want better erections, who don’t understand its risks.

2) I don’t trust advertisements! In India, advertisers are still rarely held accountable for the things they say. Advertisers and marketers know that if they say something is good for your brain, parents will spend a lot of money on it. Read a book on advertising. Know how you are manipulated.

Having a good balanced diet with enough exercise and enough rest, and studying well, will help your child do well in examinations and in life. If you want her to get more DHA, give her more fish or foods containing flax oil or seeds, but always as part of a balanced diet.
