A study of over 25,000 people found that those with the highest intake of oleic acid had a significantly lower risk of developing ulcerative colitis. Daily consumption of two-to-three tablespoons of olive oil may help prevent the disease, which affects 120,000 people in the UK.
Researchers found that a Mediterranean diet high in phenols represses pro-inflammatory genes, which could contribute to reduced cardiovascular disease risk. The study also suggests that this diet can alter the activity of immune system cells, leading to a less deleterious inflammatory profile.
Two reports in Archives of Ophthalmology found that consuming omega-3 fatty acids from fish, nuts, and olive oil was associated with a lower risk of age-related macular degeneration. Eating one serving of fish per week reduced the risk by 31%, while consuming one to two servings of nuts lowered it by 35%.
Researchers found that DHPEA-EDA protects red blood cells from damage, providing greatest protection against heart attack and stroke. The study suggests virgin olive oils contain higher levels of this compound, which could lead to the production of functional oils designed to reduce heart disease risk.
Researchers from Spain have discovered that extra virgin olive oil's polyphenols may help combat breast cancer by inhibiting the HER2 oncogene.
