The researchers tracked gene expression in blood cells after consuming two virgin olive oil-based breakfasts with varying phenolic compound content.
A new method uses isotopic analysis to distinguish olive oil from shark-derived squalene and squalane, a potential solution to stop commercial fraud and protect sharks. The technique could also promote the production of plant-based squalene, discouraging shark fishing.
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. The study confirms the anti-HER2 effect of fractions extracted from olive oil in breast cancer cell lines, suggesting a potential basis for new anti-HER2 compounds.
Researchers discover that polyphenols in extra-virgin olive oil drastically suppress the overexpression of the cancer gene HER2 in human breast cancer cells. The findings suggest a safe platform for designing new anti-breast cancer drugs.
A traditional Mediterranean diet combined with a daily serving of mixed nuts appears to be useful for managing some metabolic abnormalities in older adults. The study found that the nut group had a significant decrease in large waist circumference, triglycerides, and blood pressure compared to the control group.
Researchers at the University of Granada have developed a new method to establish the antioxidant capacity of extra virgin olive oil. The study found that the ABTS method is the most suitable for studying polyphenol content and its correlation with total antioxidant capacity.

A new study finds that both normal-weight and overweight individuals underestimate calorie content of larger meals. To improve weight loss estimates, consider doubling initial meal size estimates or estimating calories item-by-item. Meanwhile, virgin olive oil rich in polyphenols has been shown to increase 'good' cholesterol levels and...
Researchers found that phenolic compounds in olive oil improved endothelial function and reduced oxidative stress. The study suggests a possible mechanism by which the Mediterranean diet's health benefits are achieved, but further research is needed to confirm these findings.
