The NACCP process involves a sequence of analysis and controls that depart from raw material production to the evaluation of the effect of nutrition on health. It is articulated through the following points: 1) identification of nutrient level in the food;2) identification of critical control points (environmental, genetic data, chemical and physical data, production technology, distribution and administration);3) establishing critical limits that can impoverish and damage the nutrient;4) establishing measures to monitor;5) establishing corrective actions. We selected as biomarkers the total phenolic content (TPC) and total antioxidant capacity (TAC) of a genotyped Italian hazelnut cultivars (Corylus e avellana L.). We performed a clinical study evaluating: a) nutritional status;b) clinical-biochemical parameters;c) low density lipoprotein oxidation (LDL-ox);d) the expression level changes of oxidative stress pathway genes in the blood cell at baseline and after 40 g/die of hazelnut consumption. In this study, we found a significant lowering (p ≤ 0.005) of LDL oxidized proteins, in association with the consumption of 40 g/d of hazelnuts. Also, we found a significant variation (p ≤ 0.005) of gene expression of antioxidant and pro-oxidant genes, between the intake of dietary with and without hazelnuts. This results support the hypothesis that the NACCP process could be applied to obtain significant benefits in terms of primary prevention and for contributing to the amelioration of food management at the consumer level.展开更多
