Hydroxytyrosol (HOTYR) and tyrosol (TYR), main phenolic compounds of olive oil, have been reported to contribute to the prevention of cardiovascular diseases due to their antioxidant activities, e.g., protection of low-density lipoprotein (LDL) oxidation. Their bioavailability in humans is poor, and they are found in biological fluids mainly as conjugated metabolites. Low concentrations of free...

Olive oil is the most important commodities produced in the Mediterranean region. Due to its significant economical importance, the usage of pesticides in its production is systematic, by using a wide range of plant protection products with a variety of modes of action. As a consequence, monitoring of their residue levels in these products is a necessity. In the present study a reversed-phase h...

Ozonated olive oil was prepared by bubbling ozone-oxygen gas through olive oil until it solidified. Hand C-NMR spectra of the ozonated oil showed that all C-C double bonds in triacyglycerols were converted to ozonide. The spectra also showed no other structural change and the absence of degraded products of ozonide such as aldehydes and carboxylic acids. HPLC chromatogram of the oil showed thre...

The Mediterranean diet, in which olive oil is the primary source of fat, is associated with a low mortality for cardiovascular disease. Data concerning olive oil consumption and primary end points for cardiovascular disease are scarce. However, a large body of knowledge exists providing evidence of the benefits of olive oil consumption on secondary end points for the disease. Besides the classi...

BACKGROUND Olive oil is a major component of the Mediterranean diet suggested to be beneficial to counteract Alzheimer's disease. AIM OF THE STUDY Our objective was to examine the association between olive oil use, cognitive deficit and cognitive decline in a large elderly population. METHODS We followed 6,947 subjects with a brief baseline food frequency questionnaire and repeated cognitiv...

Climate change is undoubtedly the most imminent environmental issue the world is facing today. Climate changes could heavily affect olive oil producing areas, especially in the Mediterranean basin. Olive trees are tougher than vines and can thrive on many different terrains and under various climate conditions. Researchers reported that a key area of Spanish olive oil production in Catalonia ma...

Olive oil, an important component of the Mediterranean diet, is rich in polyphenols and is known to possess positive health effects relative to other dietary fats. In addition, the leaves of the olive plant (Olea europaea) contain similar phenolics (oleuropein, luteolin-7-glucoside, apigenin-7-glucoside, verbascoside and hydroxytyrosol) to those of olives and olive oil, although at higher conce...

Olive oil contains a vast range of substances such as monounsaturated free fatty acids (e.g., oleic acid), hydrocarbon squalene, tocopherols, aroma components, and phenolic compounds. Higher consumption of olive oil is considered the hallmark of the traditional Mediterranean diet, which has been associated with low incidence and prevalence of cancer, including colorectal cancer. The anticancer ...

Background: Depression is a complicated disturbance affected by a collection of biological and environmental factors. The first aim of psychiatric studies is to recognize biological markers that could be utilized to predict improvement and increase reactions to antidepressant treatments. Diet affects different aspects of health, including depression. The aim of study was to determine antidepres...
