Is there a correlation between serum cholesterol levels and self-reported moods and feelings in human subjects?
Serum cholesterol levels appear to correlate negatively with positive moods and positively with negative moods over a 2-month period.
Answers are grounded in this paper and cite their sources.
Cholesterol-mood associations are hypothesis-generating; prospective studies needed before any clinical consideration.
Correlations between serum cholesterol levels and self-reported intensities of various moods and feelings--namely, motivation, arousal, happiness, depression, anger, fear and lethargy--were investigated in 20 subjects over a 2-month period. Consistent and occasionally significant negative correlations were seen between subjects' serum cholesterol levels and their moods and feelings of motivation, arousal and happiness. Consistent and more frequently significantpositivecorrelations were evidenced between subjects' serum cholesterol concentrations and their moods and feelings of depression, anger, fear and lethargy.
