ABSTRACT
BACKGROUND:
Mental disorders are conditions that affect the usual function of the brain, causing a huge burden on societies. The causes are often unclear, but previous research has pointed out, as is the case with many other diseases, that nutrition could have a major role in it. Amino acids, the building blocks of proteins, are the main precursor of neurotransmitters (the chemical messengers in the brain) malfunction of which is heavily associated with a wide range of brain disorders.METHODS:
We assumed different sources of dietary protein could have different impacts on mental well-being. Hence, we decided to collect the nutritional data (with a validated and reliable semi-quantitative food-frequency questionnaire) from a sample of 489 Iranian women and investigate the association between animal and plant protein sources and the risk of depression, anxiety, and stress. Symptoms of these mental disorders were assessed using a validated Depression, Anxiety, and Stress Scales (DASS) questionnaire with 21 items.RESULTS:
After multivariable adjustment, it was shown that women in the highest tertile of animal protein intake were more likely to show symptoms of depression (OR 2.63; 95% CI 1.45, 4.71; P = 0.001), anxiety (OR 1.83; 95% CI 1.04, 3.22; P = 0.03), and stress (OR 3.66; 95% CI 2.06, 6.50; p < 0.001). While no significant association was seen between plant protein and any of the studied mental disorders.CONCLUSION:
Overall, our findings suggest that a diet high in animal protein could predispose individuals to mental illnesses.Palabras clave
