Diet food for thought

CSIRO is calling for young volunteers for a study into foods that boost brain power.
Scientists will test the theory that a swift rise and fall in blood glucose is bad for concentration, memory and learning.
Author and dietitian Associate Professor Manny Noakes says: "We believe that if we can let parents know what should be ideal meals and snacks for kids, we may be able to help children learn.""Foods that raise blood sugar levels very quickly and drop them very quickly might have the worst affect.
"That might include foods that we think are reasonably nutritious such as white bread and certain breakfast cereals."The team hopes to enlist 36 children, between the ages of 10 and 12, for the first study using drinks and another 36 for a study on foods. In the first study, the children will each drink a special mixture for breakfast and perform tasks on the computer.

Scientists will look for changes in attention, memory, reaction time and hunger.
Blood glucose levels will be monitored by a tiny sensor inserted under the surface of the skin on the abdomen. It will take readings every five minutes over a four-hour period.
These readings will need to be compared with the results of hourly finger prick tests.
The three drinks will contain different amounts and types of sugars, fats and protein.
Patrick, 10, and Zoe, 11, are among the earliest volunteers. Patrick says he eats weetbix or toast for breakfast and does not usually skip the meal.
Zoe has porridge but she has a favourite for special occasions.
"I like pancakes with chocolate ice cream," she said.
The first study will take place at the CSIRO clinic, Kintore Avenue, city, during the September school holidays.
Each volunteer will receive a Coles/Myer voucher worth $160 plus travel expenses.
Those interested in taking part should contact Dr Amy Slater on 8305 0611.
