El aceite de oliva en la alimentación humana
... Molte azioni delle aziende agroalimentari, tra cui quelle italiane, infatti, hanno mirato a questo aspetto (Kohls e Uhl, 1990); anche le azioni riguardanti le DOP, IGP e prodotti tradizionali rientrano in questa categoria (Gomez e Caldentey, 1999;Loureiro e McCluskey, 2000). Inoltre, anche le politiche che hanno sostenuto l'identificazione del consumatore con il proprio territorio tramite l'enfasi sulla tradizione, hanno sviluppato enormemente la loyalty dei consumatori verso prodotti di qualità superiore e i rispettivi brand (Farre, 1996). ...
The paper proposes a quantitative analysis of extra-virgin olive oils market designed to study the intra-sectoral competition and to analyze the profitability of pricing strategies for different types of companies: small produces, large manufactures, private label. The analysis focuses on trade within the modern grocery sector, which represents the first distribution channel of extra virgin olive oils at the national level. The study refers to the theory of industrial organization and, through the demand estimation, comes to the measurement of price-cost margins. The most important results relate to the concerns of the smaller producers respect to private label, big and international companies in the event of a further fall of extra virgin olive oils prices.
... Agricultural firms' new strategic framework has led to an increase in consumer preference and loyalty behavior (Kohls & Uhl, 1990). Aspects such as the creation of the protected designation of origin (PDO; Go´mez & Caldentey, 1999;Loureiro & McCluskey, 2000), the increased emphasis of brands on aspects like quality, information and design, and the cultural ''roots'' that the product has among the population of the producer countries, particularly in the Mediterranean area (Farre, 1996), have made consumer loyalty an increasingly important element in olive oil purchase behavior (Langreo, Rodrı´guez, Mili, & Sanz, 1996). Therefore, a significant brand loyalty behavior is expected. ...
Olive oil consumption is growing all around the world as a consequence of the extension of the Mediterranean diet. Because of limited production, pricing, promotions, and consumer-related variables are essential to explain olive oil consumer behavior. As a consequence of this increasing consumption, it is fundamental to analyze the main factors influencing consumers' olive oil choices for both brands and retailers to be able to compete more efficiently and satisfy consumer needs more closely. But, few such studies are concerned with olive oil (although a great many works in the literature analyze the influence of these factors in other product categories). In a sociocultural context like the Spanish market, in which brand awareness is strong and the use of the product is very high, these factors are even more important. Thus, the main objective of this article is to determine and assess how different marketing variables, such as price, price discounts, use of store flyers and loyalty, explain olive oil brand choice.

Punsar, F. Seccareccia, and H. Toshima. The diet and 15-year death rate In the Seven Countries Study. Am J Epidemiol 1986; 124:903–15
In 15 cohorts of the Seven Countries Study, comprising 11,579 men aged 40-years and “healthy” at entry, 2,288 died In 15 years. Death rates differed among cohorts. Differences In mean age, blood pressure, serum cholesterol, and smoking habits “explained” 46% of variance in death rate from all causes, 80% from coronary heart dIsease, 35% from cancer, and 45% from stroke. Death rate differences were unrelated to cohort differences in mean relative body weIght. fatness, and physical activity. The cohorts differed in average dIets. Death rates were related positively to average percentage of dIetary energy from saturated fatty acids, negatively to dietary energy percentage from monounsaturated fatty acids, and were unrelated to dietary energy percentage from polyunsaturated fatty acids, proteins, carbohydrates, and alcohol. All death rates were negatively related to the ratio of monounsaturated to saturated fatty acids. Inclusion of that ratio with age, blood pressure, serum cholesterol, and smokIng habits as inde pendent variables accounted for 85% of variance In rates of deaths from all causes, 96% coronary heart dIsease, 55% cancer, and 66% stroke. Oleic acid accounted for almost all dIfferences In monounsaturates among cohorts. All- cause and coronary heart disease death rates were low In cohorts with olive oil the main fat Causal relationshIps are not claimed but consideration of characteristics of populations as well as of Individuals withIn populations is urged evaluating risks.
