Olive oil can have a positive effect on blood cholesterol levels, heart disease, skin cancer, earaches, constipation, colon cancer, upset stomach, dry skin, and stretch marks. It also contains vitamins E, K, A and hundreds of micronutrients. Many of its health benefits are due to its high amount of monounsaturated fatty acids, antioxidants, anti-inflammatory properties, and moisturizing properties.
Olive oil has a positive effect against heart disease by controlling LDL (bad) cholesterol levels and increasing HDL (good) cholesterol levels. It is good at activating the secretion of bile and pancreatic hormones and lowering the chance of the formation of gallstones. When it is taken orally, it can increase metabolism, help digestion, and lubricate mucous membranes. Putting extra virgin olive oil on skin after sunbathing can help to prevent skin cancer.
