Olive oil is one of the oldest and most highly beloved substances on the planet, not only because it helps make food taste better, but also because it is a much healthier alternative to traditional vegetable oils. Olive oil also contains high levels of omega-3 fatty acids, which can reduce inflammation throughout the body, and make you less susceptible to cancer. Omega-3 fatty acids even act as antioxidants in some cases, lowering levels of oxidative stress and preventing the development of cancer. Add olive oil to your meals, cook with it, and even consume it plain to get this healthy boost to your system!
