Low-Fat Dairy Linked With Lower Risk of Depression
Could the type of dairy you eat affect your mental state? A recent study suggests that people who consume low-fat milk and yogurt instead of whole-fat products may have a lower risk of depression.
Participants in the study included 1,159 Japanese adults between the ages of 19 and 83, 897 of whom were men and 262 of whom were women. 31.2% of the men were depressed and 31.7% of the women were depressed.
All of the participants completed a questionnaire to determine how often they consumed whole or low-fat milk or yogurt. They also used the self-rating depression scale, which has 20 questions, to determine depressive symptoms.
After analyzing the data, the researchers found that people who consumed low-fat dairy products between one and four times a week were less depressed than those who consumed whole-fat dairy products. After adjusting for age, sex, health status, nutrition status, and lifestyle, the researchers found that the correlation remained.
There was no association found between whole-fat milk consumption and depressive symptoms.
Researchers from Tohoku University in Japan led the study. It was published online ahead of print on January 9, 2017, in Social Psychiatry and Psychiatric Epidemiology.
Dairy products are good sources of calcium, vitamin D, protein, potassium and vitamin A. Dairy consumption has been linked to bone health, diabetes prevention, weight loss, and improved mental function.
