Olive oil contains monounsaturated fatty acids, which lower the risk of heart disease, according to Mayo Clinic. These acids may lower cholesterol levels and stabilize blood clotting.
Monounsaturated fatty acids may be able to help people control their Type II diabetes by improving insulin levels and blood sugar, notes Mayo Clinic. Olive oil also contains polyunsaturated fats, which are beneficial for human health. However, olive oil is still high in calories, so consumption should be in moderation. Olive oil is low in saturated fat, which is bad for cholesterol and increases the risk of developing heart problems. One tablespoon of olive oil contains 11 grams of monounsaturated fat and 1 gram of polyunsaturated fat, reports Everyday Health.
One study shows that olive oil may decrease the risk of stroke in older adults by as much as 41 percent in comparison to those who never use the oil, explains Medical News Today. Other studies show that olive oil can reduce the odds of breast cancer. The study on depression finds that people who eat trans fat are more likely to suffer from depression than those whose main source of dietary fat comes from olive oil. Another study found that olive oil may reduce the risk of developing Alzheimer's disease.
