304 OLIVE OILS AND HEALTH cells) synthesise nitric oxide to eliminate pathogens they have engulfed. In the lungs, nitric oxide helps maintain vascular homeostasis. Reduced levels of NO lead to endothelial dysfunction and contribute to the vascular pathology seen in pulmonary hypertension. Additionally, nitric oxide plays a key role in penile erection during sexual arousal by inducing vasodilation, which increases blood flow to the penis. This increased volume causes engorgement of the erectile tissues, resulting in erection. Altered production of nitric oxide has been implicated in conditions such as atherosclerosis, hypertension, etc. Some kidney diseases are associated with reduced nitric oxide levels. very healthy healthy neutral not so healthy unhealthy NUTRI-SCORE (System) A controversial front-of-pack labelling system designed to assess the nutritional quality of pre-packaged foods. It assigns each product a letter and a corresponding colour, based on a scoring algorithm that weighs both favourable and unfavourable components of the food. The score increases with the presence of beneficial ingredients such as protein, fruit, vegetables, legumes, nuts, fibre, and healthy oils (such as rapeseed, walnut, and olive oil). Negative points are given for high amounts of energy, sugars, saturated fat, and sodium. The scale ranges from A (very healthy), the best nutritional option, to E (unhealthy).

The scientific name of the olive tree (genus: Olea; species: europaea). It belongs to the Oleaceae plant family. The final “L”. refers to the botanist who first classified this species: Carl Linnaeus (Carl Nilsson Linnæus), who also created the system of taxonomy used to classify living organisms. This binomial nomenclature system requires that the genus name begins with a capital letter and the species name with a lowercase letter.
