What is not to love about olive oil? From the unique flavor to the rich mouthfeel, olive oil is a welcomed addition to many dishes. But many may not realize that olive oil isn’t just a delicious flavor addition to salads and meats (and most recently, coffee—thanks to Starbucks). This oil offers some unique health benefits that other condiments can’t come close to.

Olive oil is rich in fat—but don’t let that scare you! While consumption of certain fats, like saturated and trans-fats, are associated with unwanted health outcomes (think the increased risk of heart disease factors), consumption of healthier fats can result in some amazing benefits. Since olive oil is rich in “healthy” monounsaturated fat, it should not be viewed in the same light as fat sources like lard and butter.

People who live by the Mediterranean Sea, and thus live in regions that produce olives, tend to eat a large amount of olive oil and reap health benefits. However, an important detail to consider is that they consume much more monounsaturated fat than saturated and trans-fats. In other words, they are consuming olive oil and other “healthier” fat sources while limiting the consumption of fried foods, processed foods, and other “unhealthy” fat sources.

If you decide to include olive oil into your diet on a consistent basis, you may be wondering what you can expect to see in terms of your health. Here are 10 things you may experience when you are sneaking in a healthy dose of olive oil in your sauces, sauté pans, and even baked goods regularly.

Macular degeneration occurs when a part of your retina, called the macula, becomes damaged. Having this condition can cause a person to have blurred or distorted vision. In some cases, those with macular degeneration may see spots. Data shows that dietary patterns that are rich in foods that contain omega-3 fatty acids, like olive oil, protect against macular degeneration better than dietary patterns that follow more of a Western style. Particular dietary patterns containing ω-3 FAs-rich foods (nuts, olive oil, and fish), such as the Mediterranean diet, seem to be protective against AMD progression compared to Western diets rich in fats and carbohydrates. And one study showed that regular use of olive oil is linked to a protective effect for late macular degeneration among an elderly population.
