The Role of Cholesterol in Mental Health
Cholesterol is essential for the production of various hormones and neurotransmitters that significantly influence mental health. Low cholesterol levels, particularly below 140 mg/dL, are associated with increased risks of depression, suicidal ideation, and aggressive behaviors. The brain, which is composed of 60% fat, relies on cholesterol for optimal function, and a deficiency can lead to impaired neurotransmitter activity. Understanding cholesterol’s benefits can help reshape perceptions about its role in mental well-being and nutrient absorption.
