Coffee intake and elevated cholesterol and apolipoprotein B levels in men

Area of Science:

• Cardiovascular Health
• Nutritional Epidemiology
• Lipid Metabolism

Background:

• Coffee consumption is widespread globally.
• Lipoprotein profiles are key indicators of cardiovascular disease (CVD) risk.
• Understanding dietary impacts on lipoproteins is crucial for public health.

Purpose of the Study:

• To investigate the association between coffee intake and plasma lipoprotein concentrations in middle-aged men.
• To determine the form and significance of the relationship between coffee consumption and specific lipoproteins.

Main Methods:

• Cross-sectional study of 77 middle-aged American men.
• Dietary intake assessed via three-day diet records.
• Plasma lipoprotein concentrations, including apolipoprotein B and LDL cholesterol, were measured.
• Statistical analyses, including correlation and adjusted models, were employed.

Main Results:

• Coffee intake positively correlated with apolipoprotein B levels (r = .27, P <= .01).
• This association strengthened after adjusting for confounding factors like age, smoking, adiposity, and aerobic capacity.
• Higher coffee intake (over 2-3 cups/day) was associated with elevated apolipoprotein B and LDL cholesterol.

Conclusions:

• Heavy coffee drinkers (more than 2-3 cups/day) exhibited lipoprotein profiles indicative of increased cardiovascular disease risk.
• The findings suggest a potential link between high coffee intake and adverse lipid profiles in men.
• Causality between coffee consumption and altered lipoprotein levels requires further investigation.
