Polyphenol Consumption and Its Association with Physical and Mental Health in Adults with Major Depressive Disorder.

Among men with MDD, polyphenol intake was positively associated with glycated hemoglobin levels.

• The association between polyphenol intake and glycated hemoglobin was statistically significant (R = 0.70; p = 0.038).
• This finding was specific to male participants in the study.
• The study included 44 participants total with major depressive disorder.

Lower polyphenol intake in women with MDD was associated with poorer physical health and overall quality of life.

• The association with physical health was statistically significant (p = 0.014).
• The association with overall quality of life was statistically significant (p = 0.013).
• This relationship was found specifically in female participants and was not reported for male participants.

Polyphenol intake moderated the effects of visceral fat content, muscle mass, severity of depressive symptoms, and severity of stress symptoms on triglyceride levels.

• Polyphenol intake enhanced the effects of visceral fat content and muscle mass on triglyceride levels.
• Polyphenol intake enhanced the positive effect of depressive symptom severity on triglyceride levels.
• Polyphenol intake enhanced the negative effect of stress symptom severity on triglyceride levels.
• These findings suggest polyphenols play a moderating or mediating role between body composition/psychological variables and lipid metabolism.

Polyphenol intake was positively associated with LDL cholesterol levels, and this relationship was attenuated by body water and fat content.

• The positive association between polyphenol intake and LDL cholesterol was moderated by body composition variables.
• Specifically, body water content and fat content attenuated the relationship between polyphenol intake and LDL cholesterol.
• This indicates body composition plays a moderating role in how polyphenol intake relates to lipid profiles in MDD patients.

Polyphenol intake weakened the relationship between fat content and quality of life with cortisol levels in individuals with MDD.

• The model examining polyphenol intake, fat content, and quality of life in relation to cortisol levels achieved R² = 0.61 (p < 0.001).
• Polyphenol intake attenuated the negative association between fat content and cortisol levels.
• Polyphenol intake also attenuated the positive association between quality of life and cortisol levels.
• This suggests polyphenols interact with body composition and psychological wellbeing in regulating cortisol in MDD.

The study assessed polyphenol intake using the Phenol-Explorer program in 44 adults with major depressive disorder.

• Health status was assessed using questionnaires adapted into Polish, body composition analysis, and laboratory blood tests.
• The sample size was 44 participants.
• Polyphenol intake was estimated using the Phenol-Explorer program, a specialized dietary assessment tool for polyphenol content.
• The study design incorporated both biological (blood tests, body composition) and psychological (questionnaire) measures.
