AT LAST, A COMMODITY WITH A FUTURE:

Extra zinc in diet 'helps pupils do better at school' (PETER RANSCOMBE, 4/11/05, The Scotsman)

A DAILY supplement of zinc can boost pupils’ performance in the classroom, a study has found.

Researchers monitored 200 schoolchildren and found that those taking more than double the current recommended daily intake of zinc had faster and more accurate memories. Their attention spans also increased.

Zinc is a naturally occurring mineral found in many everyday foods, including red meat, shellfish, nuts, seeds and wholegrains. The traditional Scottish breakfast of porridge oats is also rich in zinc, as are raspberries.

In the new study, children aged between 12 and 13 were given a specially prepared fruit juice to drink each morning before school. Some of the fruit juices had a 20mg zinc supplement added, while others had zinc added at the current recommended level of 10mg. A third set of fruit juices were left without a supplement. The children, their parents and their teachers were unaware of which juice they were being given.

The American research team, from the Grand Forks Human Nutrition Research Centre in North Dakota, saw an improvement in some children’s performance after ten to 12 weeks. But no significant improvement was noticed in the children who took the 10mg supplement or no supplement at all.

Zinc probably works better if your diet is based on deep fried Mars Bars and hagis.

If 10 mg doesn't do anything, it's hard to trust data showing that 20 mg does.
