Liver

Definition

The liver is the body's largest gland. It performs major metabolic functions: protein synthesis, detoxification, bile production, glucose, lipid, and protein metabolism.

How it works

All absorbed nutrients pass through the hepatic portal vein before reaching general circulation. The liver stores glycogen, synthesizes plasma proteins (albumin, clotting factors), produces cholesterol and bile salts, metabolizes medications and toxins.

Role

Macronutrient metabolism, detoxification, protein synthesis, bile production.

Examples

• Hepatic steatosis (fatty liver) linked to excess fructose and alcohol
• Cirrhosis
• Hepatic insufficiency

Recommendations

Limit alcohol (<10 drinks per week WHO), reduce added fructose, avoid unnecessary hepatotoxic medications.

Key takeaway

The liver is the organ that pays the price for all excesses — alcohol, sugar, and ultra-processed foods exhaust it.
