Old brown sherry—like other types of sherry—contains antioxidants called polyphenols that may offer several health benefits when consumed in moderation. Research suggests these polyphenols help reduce the risk of cardiovascular diseases by preventing the oxidation of low-density lipoproteins (LDL), commonly known as “bad” cholesterol. This process is linked to a decreased occurrence of coronary artery disease. Additionally, sherry consumption can increase the production of high-density lipoprotein (HDL) cholesterol, which is associated with longevity and reduced risk of heart disease[1][3][4].
Studies—including both animal and human research—have found that daily moderate intake of sherry (the equivalent of about 150ml for an adult) leads to:
- Lower total (bad) cholesterol levels[1][3][4]
- Increased HDL (good) cholesterol[1][3][4]
- Improved cardiovascular health, possibly including lower blood pressure and enhanced blood circulation[2][5]
Besides cardiovascular effects, other reported benefits of moderate sherry consumption—though less well-supported by scientific evidence—include:
- Delaying age-related processes
- Reducing stress and anxiety
- Potentially improving sleep quality[2]
- Low calorie content (about 58 kcal per 50ml for dry sherry)[7]
It’s important to note that these positive effects are linked to moderate consumption. Excessive intake carries health risks.
Side Effects of Old Brown Sherry
Like all alcoholic beverages, old brown sherry can cause several side effects when consumed in excess or by individuals sensitive to alcohol:
- Hangover symptoms (nausea, headache, fatigue, dehydration)[2]
- Potential for addiction and alcoholism with regular heavy use[2]
- Negative effects on metabolic health if abused[1]
Sherry should always be enjoyed responsibly to minimize these risks. Any health benefits are quickly outweighed by the dangers of excessive alcohol consumption.
