Both the oils are plant-based and contain roughly 120 calories per tablespoon. Both are rich in polyunsaturated and monounsaturated fats (1), (2). These kinds of fatty acids are known to bring down the bad cholesterol in your blood while promoting good cholesterol (3), (4).

  • Linoleic Acid In Sunflower Oil: Sunflower oil contains almost 65% linoleic acid while olive oil contains just 10% of it. It also contains omega 3 fatty acids and omega-6 omega 6 fatty acids, which enhance neurological functions and reduce inflammation (5).
  • Oleic Acid In Olive Oil: Oleic acid is a monounsaturated fatty acid, which is known to suppress oncogene in the body. So, the next time you use olive oil for your Caesar salad dressing, remember, you are fighting cancer as well! It is suggested that the consumption of meat may increase the risk of colorectal cancer. There is evidence that oleic acid may protect cells from mutating into cancerous cells and promote the death of cancerous cells (6), (7), (8), (9).

In some South American cultures, making food with sunflower oil is a community ritual because its flowers are considered sacred as they face the sun.

Vitamin E:

Vitamin E should be taken in healthy doses every day because of its various benefits. It reduces the formation of free radicals, which can lead to the development of certain types of cancer or chronic diseases. Vitamin E also prevents vascular complications like arteriosclerosis, chest pain, leg pain due to arterial blockage, etc.. It also alleviates diabetes and its symptoms. Vitamin E is used for asthma, skin disorders, cataracts, etc (10), (11), (12).

  • Sunflower oil:It is a rich source of vitamin E. It has been found that vitamin E found in sunflower oil can also prevent rheumatoid arthritis and colon cancer. People from countries that use olive oil and sunflower oil as their main cooking oils are found to have lower asthma rates (1), (13), (14).
  • Olive oil: This oil with a goldish-green color also contains a good proportion of Vitamin E. It is extensively used for cooking Mediterranean cuisine. The vitamin E found in other oils like canola, corn, or soybean is found in the gamma-tocopherol form, which has a negative impact on lung function. But olive oil and sunflower oil both contain vitamin E in the alpha-tocopherol form which has no such adverse effect (2).

Vitamin K:

Vitamin K is another important nutrient that provides various health benefits. It serves as an important factor in the blood clotting mechanism and stops excessive bleeding. It also strengthens the bones and can prevent osteoporosis in older women.

    It has barely 1 microgram of vitamin K per tablespoon.

From the above comparison, it is clear that olive oil is healthier than sunflower oil in terms of Vitamin K content, fatty acids, and minerals. Olive oil does not interfere with the omega 6 fatty acid and omega 3 fatty acid balance, whereas sunflower oil may increase the ratio of these fatty acids. The polyunsaturated fats in sunflower oil can make it go rancid more easily than olive oil. Olive oil also has a fruity taste unlike sunflower oil, which is bland.

The presence of higher amounts of vitamin K, fats, and minerals in olive oil makes it a clear winner over sunflower oil. Moderate intake of these plant oils that are low in saturated fats may help strengthen bones, prevent osteoporosis, and stop excess bleeding. The vitamin E in these oils may help prevent colon cancer and rheumatoid arthritis. However, the polyunsaturated fats in sunflower oil can make it go rancid easily (as compared to olive oil). But the two oils can improve the ratio of omega 3 to 6. Hence, choose the right cooking oil to reap the right benefits.
