You know I’m a big believer of “food as medicine” and avoiding actual medication and the unpleasant side effects whenever possible.
I love that quote from Hippocrates, the father of medicine, who said, “Let food be thy medicine, and let medicine be thy food.”
And that’s why I’d like to talk with you today about the 10 big health benefits of olive oil.
In fact, it was Hippocrates himself who dubbed olive oil “the great therapeutic.” The ancient Greek physician identified more than 60 medicinal uses for olive oil.
Fortunately, after two and a half millennia, modern science is beginning to catch up with the wise, old Hippocrates. Many clinical studies, including the large-scale PREDIMED trials to evaluate the effects of the Mediterranean diet, have demonstrated olive oil’s role in preventing chronic diseases.
A delicious component of a nutritious diet, olive oil and its consumption may also be considered preventive healthcare—with topical therapeutic uses, too.
Important note: In order to reap the health benefits of olive oil, it is crucial that you procure extra virgin olive oil (EVOO). It’s the only grade of olive oil that retains its natural phenols (antioxidants) and other active compounds. (EVOO is minimally processed, whereas other oil grades, such as virgin, “pure,” or “light,” have been industrially refined and the healthful phenols destroyed.)
“The Fresher, the Better” — America’s Test Kitchen
Also, remember olive oil is never more flavorful—or bursting with more super-healthy polyphenols—than when it’s fresh-pressed. This is why, as the culinary experts at America’s Test Kitchen put it, when it comes to olive oil, “the fresher, the better.”
It’s also why medical professionals recommend selecting EVOO from the most recent olive harvest as a strategy for obtaining the highest-quality, highest-phenolic oil. (Here is a source, The Fresh-Pressed Olive Oil Club—the only one I know of that ships independently lab-certified 100% pure EVOO direct from the harvest. It’s a great way to get farm-fresh EVOO shipped right to your door. I actually have a couple bottles in my cupboard from the last harvest.)
10 Proven Health Benefits of Olive Oil
1. Can reduce the risk of heart disease.
Two tablespoons of EVOO per day can reduce your risk of heart disease by improving blood cholesterol levels: lowering LDL (“bad”) cholesterol and increasing HDL (“good”) cholesterol.
Heart disease can affect people of all ages, although the risk increases as you get older. Rising obesity levels in the US and around the world have lowered the average age of onset of heart disease risk factors such as atherosclerosis (“hardening of the arteries”), which can start as early as childhood.
2. Can help prevent type 2 diabetes.
Several studies have shown that EVOO as part of the Mediterranean diet can help prevent type 2 diabetes. In a PREDIMED study, the group of people who ate an olive oil–rich Mediterranean diet reported 40% fewer cases of diabetes than the control group (who did not consume olive oil). In another study, which evaluated people at risk for diabetes, two tablespoons per day of EVOO, along with fiber, reduced fasting and 2-hour glucose (blood sugar) to normal, non-diabetic levels.
3. May protect against breast cancer.
A long-term PREDIMED study suggests that a Mediterranean diet enriched with EVOO (1 liter a week for participants and their families) helps protect against breast cancer. Olive oil consumption is also inversely related to breast density: women who consume greater amounts of olive oil are less likely to have high breast density, a risk factor for breast cancer.
