Crime fighting at the dinner table

Some case studies show that the solution to behavoral problem may be a easy as a change in diet.
Stephen Schoenthaler, a criminal-justice professor at California State University in Stanislaus, has been researching the relationship between food and behaviour for more than 20 years He has proven that reducing the sugar and fat intake in our daily diets leads to higher IQs and better grades in school. When Schoenthaler supervised a change in meals served at 803 schools in low-income neighbourhoods in New York City, the number of students passing final exams rose from 11 percent below the national average to five percent above. He is best known for his work in youth detention centers. One of his studies showed that the number of violations of house rules fell by 37 percent when vending machines were removed and canned food in the cafeteria was replaced by fresh alternatives. He summarizes his findings this way: “Having a bad diet right now is a better predictor of future violence than past violent behaviour.”
But Schoenthaler’s work is under fire. A committee from his own university has recommended suspending him for his allegedly improper research methods: Schoenthaler didn’t always use a placebo as a control measure and his group of test subjects wasn’t always chosen at random. This criticism doesn’t refute Schoenthaler’s research that nutrition has an effect on behaviour. It means most of his studies simply lack the scientific soundness needed to earn the respect of his colleagues.
