In order to evaluate and identify the antioxidant properties and the phytochemical characteristics, as well as the role of the genetic background and the different fruit parts in the definition of fruit quality, we characterized the existing germplasm through nuclear simple sequence repeats (SSRs) and evaluated the genetic divergence between ancient S. Giovanni varieties ( L.) and different types of grafting in relation to some variables of fruit quality.

Results: For each group of foods, suitable and easily measurable indicators were identified. Two macro-indicators were used to assess the nutritional sustainability of each product.
Objectives: To explore age at death (AD), overall and for different causes of death, in a cohort followed up to quasi-extinction.
Materials And Methods: In 1960, in the Italian Rural Areas of the Seven Countries Study, 1712 men aged 40-59 years were enrolled, examined and then followed up for 50 years. AD was computed for all fatal events and compared across 12 groups of causes of death.
This work aims at evaluating the main nutrients (proximate, minerals), their contribution for Dietary Reference Values in Italian population, and the antioxidant properties of some popular dishes prepared in a dedicated lab-kitchen: spaghetti alle vongole, pomodori al riso, gateau di patate, carciofi alla romana, pan di Spagna. Results showed that nutrient contents and energy value varied extensively because of the variety and the nature of ingredients in the analyzed dishes, and thus defined different daily nutrient intakes and their association with health effects. A serving portion of either spaghetti alle vongole or carciofi alla romana showed to contribute to the daily nutritional recommendations respectively, with an appreciable percentage of available carbohydrates (30-22%) and a considerable content of dietary fibre (91%).

Material And Methods: A 40-59 aged male population of 1712 subjects was examined and followed-up for 50 years. Baseline smoking habits, working physical activity and dietary habits were related to 50 years mortality subdivided into 12 simple and 3 composite causes of death by Cox proportional hazard models.
Phytochemicals can exert their bioactivity without reaching the systemic circulation; scarcely absorbed antioxidants might reach the large bowel contributing to protection from oxidative damage-induced gastrointestinal diseases. In the present work, we aimed to study the relationship between potential activity of polyphenol-rich extracts from Cichorium intybus L. and changes in morphological characteristics on Caco-2 cells.

The interactions among bioactive components, which contribute highly to the total antioxidant capacity of cereals, represent the first step in the evaluation of food potential health benefits. This research focused on the determination of antioxidant properties in grains and whole flours of some traditional Italian wheats.

Material And Methods: In the Italian Rural Areas of the Seven Countries Study of Cardiovascular Diseases, 1677 heart disease-free men aged 40-59 years were followed up during 50 years for lifetime incidence of heart disease up to the age of 90 years. They were classified as coronary heart disease (CHD) and heart diseases of uncertain etiology (HDUE).

Plant lignans were quantified in flours by means of HPLC. In addition, the FRAP of plant lignans (secoisolariciresinol, lariciresinol, isolariciresinol, pinoresinol, matairesinol), their mixture and enterolignans (enterodiol and enterolactone) were determined.

Within the phytochemicals, lignans are of increasing interest for their potential anticarcinogenic, antioxidant, estrogenic and antiestrogenic activities. The aim of this work is to contribute to the updating of food lignan databases by providing the profile and the amount of lignans in cereals, buckwheat and several cereal based foods commonly consumed in human diets.

Material And Methods: A sample of 1712 Italian men aged 40-59, first examined in 1960, was followed-up for mortality for 50 years. The length of survival was estimated as a function of 48 personal characteristics and risk factors using the multiple linear regression.
The aim of this randomised, double-blind, crossover study in normolipidaemic volunteers was to investigate the effect of consumption of an experimental cheese (from cows fed a grass and maize silage-based diet with 5% of linseed oil added) or a control cheese (without linseed oil) on both plasma lipids and fatty acid content of serum lipid fractions. A lower content of medium-chain saturated fatty acids as well as a higher content of stearic acid and polyunsaturated fatty acids were found in the experimental cheese; its consumption was successful in limiting the enhanced blood concentration of atherogenic fatty acids, without affecting fatty acid content of serum lipid fractions. These results indicate that dairy products could be considered as key foods for fat modifications with the objective of optimizing their nutritional quality.

Methods: An observational study was conducted on 131 healthy free-living subjects. Dietary intake was assessed by dietary diary.
The present study investigated the effect of the consumption of two cheese varieties differing for fat quality on blood lipid profile and redox status biomarkers in 30 selected healthy volunteers, consuming either the experimental cheese (from milk produced by cows fed a grass and maize silage based diet with 5% of linseed oil added) or the control cheese (from normal cows' milk) for 4 weeks according to a crossover design. The experimental cheese had a lower content of medium-chain saturated fatty acids and a higher content of stearic acid and polyunsaturated fatty acids; its consumption led to higher levels of vitamins C and E and stearic acid in blood, while myristic acid and oxidized low-density lipoprotein concentrations were significantly lower. As myristic acid and oxidized low-density lipoprotein are highly correlated with increased atherogenic risk and vitamins C and E with antioxidant activity, the enrichment of cows' diet with linseed oil could provide a dietary option to prevent cardiovascular diseases risk.

CD36 (cluster of differentiation 36), a class B scavenger receptor, might be involved in tissue vitamin E uptake and thus would influence blood vitamin E concentrations.
Objective: The goal of the study was to assess the association between CD36 single nucleotide polymorphisms (SNPs) and plasma α-tocopherol concentrations in humans.
Strawberries contain many antioxidant phytochemicals such as vitamin C, carotenoids and phenolic compounds including anthocyanins (ACN). In the present study, antioxidant composition of fresh strawberries (FS) and stored strawberries (SS) and the bioavailability of the main strawberry bioactive compounds were determined in human subjects. Thirteen healthy volunteers consumed 300 g of FS and SS on two separate occasions.

Moreover, due to the intensive metabolism during absorption, the metabolites circulating in blood differ from the parent compounds found in food. Thus, it is difficult to predict potential in vivo effects of phenolic compounds merely by their contents in foodstuffs.

We have emphasized the attention on the following carotenoids present in food and human tissues: beta-carotene, beta-cryptoxanthin, alpha-carotene, lycopene, lutein and zeaxanthin; we have reported the major food sources and dietary intake of these compounds. We have tried to summarize positive and negative effects of food processing, storage, cooking on carotenoid content and carotenoid bioavailability.
