If you drink olive oil daily, you can observe positive effects on your body. Olive oil intake aids in weight loss, improves digestion, and enhances heart health. The healthy monounsaturated fats present in olive oil can lower bad cholesterol levels and reduce the risk of heart disease. Olive oil also supports healthy skin, reduces inflammation, and protects against Alzheimer's disease. However, it is essential to consume olive oil in moderation as excessive intake may lead to weight gain and digestive issues.
