Link Between Processed Foods and Depression

Link Between Processed Foods and DepressionThe latest research has linked processed foods with risks of depression.

More specifically, the research indicates that people whose diet consists of more vegetables, fruit and fish actually maintain a lower risk of depression, says the University College London team responsible for the findings. Data was taken concerning the diet of 3,500 middle-aged civil servants and then compared with their cases of depression five years later, according to the British Journal of Psychiatry.
The team states that the study was actually the first in the UK to look at diet and depression.
They split the participants into two types of diet - those who ate a diet largely based on whole foods, which includes lots of fruit, vegetables and fish, and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat, refined grains and high-fat dairy products.
They then accounted for factors such as gender, age, education, physical activity, smoking habits and chronic diseases, and found a significant difference in future depression risk with the different diets.
Those who ate the most whole foods had a 26% lower risk of future depression than those who at the least whole foods.
However, those with a diet high in processed food had a 58% higher risk of depression than those who ate very few processed foods.
Although the researchers admit that they cannot totally rule out the possibility that people with depression may eat a less healthy diet, they do not believe it is the cause of the findings, for there was no association with diet and previous diagnosis of depression.
Furthermore, the study’s author, Dr Archana Singh-Manoux, pointed out there is a chance the finding could be explained by a lifestyle factor they had not accounted for.
It is not yet clear why some foods may protect against or increase the risk of depression, but scientists believe inflammation may be related as in conditions such as heart disease.
As Dr. Andrew McCulloch, chief executive of the Mental Health Foundation, points out, "This study adds to an existing body of solid research that shows the strong links between what we eat and our mental health. "
