New research suggests that eating particular foods may actually be an effective antidote for depression and other
psychiatric illness. The research will be presented at the annual conference of the New Zealand Dietetic Association,
which takes place from 5 to 7 September 2001 in Christchurch.
Key speakers at the conference include Dr Karen Silvers from Crop and Food Research and Dr Richard Porter, senior
lecturer in Psychiatry at the Christchurch School of Medicine.
Dr Silvers, who will be giving a lecture on fish and mood, says; “New Zealand has one of the highest rates of major
depression and one of the lowest levels of per capita fish consumption in the world. Our research has shown that there
is a significant relationship between fish consumption and the self-reported mental heath of New Zealanders.”
Dr Silvers will be presenting information on the mechanisms that are thought to be involved in improving mood amongst
fish consumers in New Zealand.
Fish isn’t the only food that is thought to help those who are depressed. A component of protein foods called
‘tryptophan’, may also help people with depression.
Dr Richard Porter, who will be giving a lecture on the effects of dieting on mood, says; “There have been various
studies of either low-tryptophan diets or tryptophan supplementation in psychiatric illness. There is some evidence that
tryptophan may be a useful anti-depressant. Also, there have been reports of an improvement in cognitive function in
schizophrenia amongst those people following a low-tryptophan diet, although the evidence in this area is less clear.”
Dr Porter will be presenting information at the conference on the effect of tryptophan-depleted diets on mood,
schizophrenia and Alzheimer’s disease.
The three-day conference is aimed at presenting new research and information to dietitians and allied health
professionals in New Zealand. A range of other topics will also be covered including the safety of herbal supplements
and combating nutrition misinformation.
