Wine’s Place in the Alcohol- Health Discussion

The U.S. Surgeon General’s recent advisory highlights the link between alcohol consumption and cancer, identifying it as the third leading preventable cause of cancer in the U.S. While alcohol increases the risk of at least seven types of cancer, the advisory raises questions about treating all alcoholic beverages equally, particularly wine.

Unlike other alcoholic beverages, moderate wine consumption, especially red wine, has been associated with potential health benefits, including reduced risks of cardiovascular diseases and longer lifespans, particularly within the Mediterranean diet. Studies show that moderate wine intake may not significantly increase cancer risk, unlike beer and spirits, and may even offer protective effects under specific conditions.

Public health efforts should aim for realistic, evidence-based policies. Prohibiting alcohol entirely is impractical, but encouraging moderate, mindful wine consumption within a balanced diet could help reduce harm while respecting cultural traditions. Education, not prohibition, is key to empowering individuals to make informed health decisions

Blanching of olive fruits before storage at different conditions: Effects on oil yield, lipase activity and oxidation

This study examined the impact of blanching olives and various storage conditions on the quality of extra-virgin olive oil. Blanching, achieved by immersing olives in hot water at 100°C for 3 min, effectively reduces lipase activity, preserves phenolic compounds, and enhances oxidative stability, especially when combined with cold storage at 8–10°C in perforated crates. Although the oil yield was slightly lower under cold conditions, the overall quality of the oil, including lower free fatty acid levels and higher antioxidant activity, was significantly improved. These findings highlight blanching and optimized storage as practical strategies to enhance the quality of olive oil production.

Enhancing Cantal cheese quality with olive leaf extract: A scientific exploration

This study explored the incorporation of olive leaf extract (OLE) into Cantal cheese to enhance its quality, functionality, and shelf life. OLE, which is rich in phenolic compounds such as oleuropein, significantly increased the antioxidant activity and microbial stability of cheese, inhibiting spoilage and pathogenic microorganisms without compromising its nutritional composition. Textural properties, such as hardness and cohesiveness, improved due to protein-polyphenol interactions, although slight changes in elasticity and color were noted. These findings highlight OLE’s potential of OLE as a natural preservative and functional ingredient, offering sustainable solutions for repurposing olive byproducts. Optimizing OLE concentrations to maintain beneficial microbial activity and ensure consumer acceptance remain key areas for further research. This innovative approach aligns with modern sustainability and health trends, paving the way for advancements in the dairy and functional food markets.
