Olive oil for depression prevention? Depending on the quality of oils you ingest, the incidence of depression is different

Spanish people and Italians may have "cheerful and bright" images, but indeed it seems that in the southern part of Europe actually the incidence of depression is lower compared to the northern part. Various factors such as climate and solar radiation amount have been tied to this, but the secret may have been olive oil.

According to a survey conducted in Spain, how to use grease in eating habitsdepressionIt is clear that it is related to the risk of.

Details are as below.Depression Risk Higher With Trans Fats, Lower With Olive Oil Consumption

University of Las Palmas de Gran CanariaDr. Almudena Sánchez-Villegas, Associate Professor of Preventive Medicine at Las Palmas de Gran Canaria University, et al., Conducted a survey of more than 12,000 people,Trans fatty acidPeople who are eating a diet that intensifiesdepressionThe risk of high is revealed.

The data used for the analysis is based on a questionnaire survey program involving more than 12,000 adults who graduated from college in Spain. In this program, which began to recruit participants in 1999, a questionnaire to participants every two years The average of the period during which the participants were to be tracked was 6 years and the average age at the start was 37.5 years. Although there was no depression at the beginning, 657 people reported that they were diagnosed as depressed by physicians or prescribed antidepressants during the follow up period.

Dr. Sánchez-Villegas and colleagues included in the food from answers to the questionnaire surveyed on the ingestion habits of 136 items of the dataSaturated fatty acid·Polyunsaturated fatty acid·Monounsaturated fatty acid·Trans fatty acid, And investigated the difference in depression risk due to differences in ingestion habits of oils and oils in addition to the intake of edible fats and oils such as olive oil, seed oil, butter and margarine.

As a result, the proportion of people who eat diet high intake of trans fatty acids is 48% higher in depression compared with the group not so, and the higher the intake of trans fatty acids, the higher the incidence of depressionDose response relationshipIt is said that it was seen.

In Spain, which is based on a Mediterranean diet, the intake of trans fatty acids is originally low, and trans fatty acids ingested by the Spaniards on a daily basis are around 0.4% of the total energy. By the way, in Japan it is estimated to be even lower 0.3%, but in the USA and others where trans fatty acids are said to account for about 2.5% of total energy intake, the discovery this time will have more important meaning .
