Eating foods high in trans-fats(fats present in artificial form in industrially-produced cakes and fast food...) and saturated (饱和的) fats increases the risk of depression, according to a Spanish study, confirming previous studies that linked “junk food” with the disease. Researchers also showed that some products, such as olive oil, can fight against the risk of mental illness.
Authors of the wide-reaching study, from the universities of Navarra and Las Palmas, followed and analyzed the diet and lifestyle of over l2,000 volunteers over six years. When the study began, none of the participants had been diagnosed with depression; by the end, 657 of them were new sufferers.
“Participants with an increased consumption of trans-fats presented up to a 48 percent increase in the risk of depression when they were compared to participants who did not consume these fats,” the head study author said. “The more trans-fats were consumed, the greater harmful effect they produced in the volunteers.”
The research team found, at the same time, that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil, these products are associated with a lower risk of suffering depression.
The report, published in the online journal PLOS ONE, noted the research was performed on a European population that enjoys a relatively low intake of trans-fats—making up only 0.4 percent of the total energy taken in by the volunteers. “Despite this, we observed an increase in the risk of suffering depression of nearly 50 percent,” said researcher Miguel Martinez. “On this basis we think it of great importance to take this effect into account in countries like the United States, where the percentage of energy derived from these fats is around 2.5 percent.”
The report pointed out that the current number of depression sufferers in the world is around l50 million people, and has increased in recent years. This rise is attributable, according to the authors, “to great changes in the sources of fats consumed in Western diets, where we have replaced certain types of beneficial fats in nuts, vegetable oils and fish with the saturated and trans-fats found in meats, butter and other products such as mass-produced cakes and fast food.”

People often eat food to feel better. Recently, researchers have found that eating chocolate or drinking water can reduce pain, and reduce a rat’s response to heat.
The study was done by Professor Mason and Professor Foo at the University of Chicago. It is the first to show that this powerful painkilling effect occurs while the animals are ingesting(吸收) food.
In the experiments, rats were given either a chocolate chip to eat or had sugar water or common water flowed directly into their mouths. As the rat ate the chocolate or fluid, a light under the cage was turned on. It was done to provide heat that usually caused the animal to lift its foot off the floor. The researchers found that rats were much slower to raise their feet while eating or drinking, compared to tests done while they were not eating.
Surprisingly, the researchers found no difference in the delayed foot-lift response when the rat was eating chocolate and when it was drinking water. Former research showed that only sugary things reduce people’s response to pain.
“This really shows it has nothing to do with calories,”Professor Mason said.“Water has no calories, but it has the same effect as chocolate chip. It’s really shocking.”
The researchers believe that this effect is also present in humans. The painkilling effect can be turned to our advantage. For example, water perhaps can take the place of candy which is often used to calm children—or even adults—in the doctor’s office.“Eating is a painkiller, but we don’t need the sugar,”Professor Mason said.“So replace the doctor’s candy with a drink of water.”
