It’s no secret that fast foods are harmful to health. A new study comes to show that fast food has an effect on the psyche.
Consumption of food rich in saturated fats and trans fatty acids (found in all the ingredients in fast food) increases the risk of developing depression, according to a Spanish study published in the US.
The study – which monitored the progress of over 12,000 subjects for six years – found that volunteers who ate the saturated fats and trans fatty acids pose a risk of depression by 48% higher compared with volunteers who have consumed foods containing these fats.
The survey was conducted on a group of people who consume relatively low amounts of trans fatty acids – on average only 0.4% of total caloric intake of food, said Dr. Almudena Sanchez-Villegas, a professor at the University of Las Palmas de Gran Canaria Spain, the main author of the study. In the US, the amount of trans fatty acids in the diet of the inhabitants can reach up to 2.5%, further increasing the risk of depression.
The study also revealed that food used in Mediterranean cuisine (eg. olive oil – rich in monounsaturated fatty acids such as Omega-9) may cause a reduction in risk of onset of mental illness, according to Mediafax.
