Delplanque1, Q. Du2, J C. Martin2, P. Le Ruyet3 1 NMPA, CNPS, Universite-Paris-Sud, Orsay, France 2 INRA1260/Inserm1025, Fac de médecine de la Timone, Marseille, France 3 Lactalis R&D, 8 Fromy, Retiers, France Background and objectives: DHA is the major brain FA and omega-3 deficiencies during gestation/lactation could have dramatic impacts on health during adulthood. The aim of the present study was to evaluate: 1/ the impact of dietary deficient or ALA-rich diets during gestation/lactation on the brain DHA levels of post-weaning young males submitted to deficient or ALA rich-diets; 2/ the specific impact of different matrix: butter fat compared to rapeseed oil diets to restore or maintain brain DHA levels in young rats born from deficient or ALA-rich dams. Methods: Two groups of dams were fed during gestation and lactation with either a deficient ALA-palm diet containing minimal ALA level (0.4%) or a protective ALA-rich (8%) pure rapeseed oil diet. After weaning, 3groups of young males born from deficient and ALA-rich dams received a 10% fat diet for 6 weeks, either (i) as ALA-deficient-palm diet (ALA 0.4%), (ii) ALA-lowbutter diet (ALA 0.8%), (iii) ALA-rich-rapeseed diet (ALA 8%). Results: - New-born and weaning pups from deficient dams showed brain DHA levels 2 times lower than those from ALArich-dams. - The brain DHA levels of the post weaning rats were more dependent of the dams status than of their own diet: an ALA-rich diet during gestation and lactation is protecting against ALA deficiency during post-weaning growth, while an ALA-rich diet post-weaning allow a recovery for those born from deficient-dams, but never reach the values of those born from ALA-rich-dams.- Butter fat, despite 10 times less ALA than rapeseed oil (0.8% vs 8%), is as efficient as rapeseed to restore the Brain DHA level in young rats born from deficient-dams and to maintain similar levels for those born from ALA-rich-dams. The same low n6/n3 ratio in these two type of fats (3 while 25 for palm) and the complexity of the composition of dairy fat could be part of their protective effect.

Martins,1 1 1CI&DETS Department of Food Science, IPV-Escola Superior Agrária de Viseu, Viseu, Portugal Background and objectives: The diet quality is a major factor regarding the healthy growth of children. The prevalence of childhood obesity in the “developed countries” has increased in the past decades. This became an important issue in public health nutrition. This work reflects a nutritional analysis of a 1st /2nd cycle college education throughout the workweek. The aim was to verify whether the school feeding was balanced and provided enough nutrients to allow optimal growth and development of children in these ages (6-15 years). Methods: The Dietary Guidelines for Americans 2010 was used to choose a healthy eating pattern. In order to access the different nutritional values it was used, as benchmark, the DIAL analysis program. Results: In terms of cooking methods, it was noted the predominance of techniques that led to higher caloric intake of food, especially frying (shallow and deep). The Wednesday and Thursday days had nutritional values that disrupt the parameters of a healthy diet: overall energy intake and high percentage of lipids. Meals of Monday, Tuesday and Friday were balanced. Conclusions: Among the analyzed menus, the Monday one was more balanced and adjusted to the physical activity in this age group (considering that children exercise twice a week). An economic estimation of the served menus was also object of study. Key words: children, cooking methods, nutritional evaluation.. PO699 NUTRITIONAL ASSESSMENT OF SOME MENUS SERVED AT THE AGRARIAN SCHOOL OF VISEUESAV M J. Lima, F. Varandas, C. Marques 1 CI&DETS, Department of Food Industry, ESAV-IPV, Quinta da Alagoa, Estrada de Nelas, Viseu, Portugal Background and objectives: The concern for prospective nutritional meals has increased over time. Adolescent’s obesity constitutes an important issue to be studied in Portugal. Moreover, recent studies affirm that more than 30% of our adolescents have severe obesity problems. This study was performed in order to evaluate the nutritional quality of the menus served at Agriculture School of Viseu- ESAV, throughout a workweek, Ann Nutr Metab 2013;63(suppl 1):1–1960. 595. Downloaded by: 198.143.43.1 - 3/10/2016 3:24:30 PM. Conclusions: In order to reduce the use of cooking oils and improve the consumption of cereals, vegetables and dairy products, pregnant women in Deyang region need access to culturally sensitive nutrition education sessions..
