Tomato sauce enriched with olive oil has a greater effect on heart risk factors than just raw tomato sauce.

Olive oil enhanced the cholesterol-lowering properties of high-density lipids and protected cells from oxidative stress.

In non-smoking women, olive oil decreased blood glucose as well as endothelin-1. This explains the effect of olive oil decreasing blood pressure among hypertensive women,

Olive oil increases lipid cholesterol. It also reduces the oxidative damage to lipids, decreases inflammation and improves tissue function,

Insufficient Proof For

A combination of olive and fish oil have a synergistic effect on lipid metabolism and oxidative stress in patients.

Additionally, it is likely to cause the reversion of this illness.


Depressed patients were given a diet that included olive oil and evaluated over the period of time. They revealed a decrease in depression scores.

Olive consumption is inversely associated with melancholy risks and improved depressive symptoms.

Oil with vitamins may be beneficial to include in the diet of girls to assist for bone security and against oxidative stress.

Extra Virgin Olive Oil Helps With Wound Healing

Cancer Research and Extra Virgin Olive Oil

Higher olive oil intake may be a protective factor against breast cancer.

Another polyphenol, oleuropein, can cause programmed cell death in breast cancer, colorectal cancer, and thyroid cancer.

Olive oil diets also influenced the expression of age-related changes. Diets can regulate the different susceptibility to chemical exposure leading to breast cancer.
