Does wine raise cholesterol?
Quick answer
Wine's effect on cholesterol is paradoxical. Moderate red wine consumption may increase HDL cholesterol ('good cholesterol') by 5-15%, according to some studies (Gepner et al., 2015). However, excessive alcohol raises triglycerides and total cholesterol. Wine itself contains zero cholesterol (it's a plant product). Consult a healthcare professional for a personalised lipid profile assessment.
Detailed answer
Wine contains zero cholesterol — it's a plant product. But the ethanol and polyphenols it contains interact with lipid metabolism in complex ways.
The documented positive: ethanol (regardless of beverage) increases the liver's production of HDL cholesterol ('good cholesterol'), which transports cholesterol from arteries to the liver for removal. The CASCADE trial (Gepner et al., 2015, Annals of Internal Medicine), a 2-year randomised study of 224 type-2 diabetics, showed red wine increased HDL by 10-15% compared to the control group (water). White wine had a smaller effect.
The negative: excessive alcohol consumption (> 3 glasses/day) significantly raises blood triglycerides (+30-50%), an independent cardiovascular risk factor. Alcohol stimulates hepatic synthesis of VLDLs (Very Low-Density Lipoproteins), precursors to circulating triglycerides.
Red wine-specific polyphenols (resveratrol, quercetin, catechins) have shown in vitro inhibition of LDL cholesterol oxidation. It's oxidised LDL — not native LDL — that initiates atherosclerotic plaque formation.
Bottom line: moderate consumption (1-2 glasses/day) may have a favourable effect on lipid profile. Excessive consumption has the opposite effect. The net balance depends on dose, individual genetics, and overall lifestyle.
Consult a healthcare professional for a personalised lipid profile and don't change your alcohol consumption based on health considerations without medical advice.
