Extra Virgin Olive Oil + Health
Fats are one of three macronutrients essential to human life and make up a large part of our bodies. We wouldn’t be able to absorb vitamins A, D, E or K without fat in our diets. Healthy fats, such as extra virgin olive oil, can even help you fight stress, improve mood swings, decrease mental fatigue and can actually help you manage your weight. While fat in general gets a bad reputation, not all fats are bad, (in fact they are good), you just have to make the right choices! Harvard School of Public Health recommends some healthy fat intake; as a rule of thumb, out with the bad, in with the good.
