    Objective Dietary intake and nutritional status of antioxidant vitamins have been reported to protect against some cancers the objective of the present study was to assess the correlations between serum levels of carotenoids (including beta-, alpha- and gamma-carotene), lycopene, retinol, alpha- and gamma-tocopherols, and dietary intakes estimated by an FFQ, among low-income women in the Brazilian Investigation into Nutrition and Cervical Cancer Prevention (BRINCA) study.Design Cross-sectional study of data for 918 women aged 21-65 years participating in the BRINCA study in São Paulo city. Multiple linear regression models were used with serum nutrient levels as the dependent variable and dietary intake levels as the independent variable, adjusted for confounding factors.Results in energy-adjusted analyses, the intakes of dark green and deep yellow vegetables and fruits (partial R(2) = 4.8%), total fruits and juices (partial R(2) = 1.8%), vegetables and fruits (partial R(2) = 1.8%), carrots (partial R(2) = 1.4%) and citrus fruits and juices only (partial R(2) = 0.8%) were positively correlated only with serum total carotene levels, after adjusting for serum total cholesterol concentration, age, hospital attended, smoking status. BMI and presence of cervical lesions Multiple-adjusted serum levels of carotenoids were positively correlated with intake quartiles of dark green and deep yellow vegetables and fruits and total fruits and juices independent of smoking status.Conclusions the intake of specific fruits and vegetables was an independent predictor of serum total carotene levels in low-income women living in São Paulo

    Fruits and vegetables in the Brazilian Household Budget Survey (2008-2009): carotenoid content and assessment of individual carotenoid intake
    (Academic Press Inc Elsevier Science, 2016) Vargas-Murga, Liliana; Rosso, Veridiana Vera de [UNIFESP]; Mercadante, Adriana Zerlotti; Olmedilla-Alonso, Begona; Universidade Federal de São Paulo (UNIFESP)
    The beta-carotene, alpha-carotene, beta-cryptoxanthin, lycopene, lutein, zeaxanthin, neoxanthin, violaxanthin concentrations in raw fruits and vegetables were compiled (19 fruits, 24 vegetables, and mixed fruit and salad dishes), using data from foods collected and analyzed in Brazil, by means of high-performance liquid chromatography with diode array detection. The food intake was obtained from the Food Consumption Module of the Household Budget Survey (2008-2009), recorded in 13569 households, representative of all Brazilian regions. Vegetables contributed more to vitamin A intake than fruits (70.3% vs 21.5% retinol equivalents), raw salads, pumpkin, kale and carrot being the main contributors. The mean dietary intakes of fruits (86 g/d) and vegetables (64 gid) did not meet the recommendation of the WHO/ FAO. All food items supplied beta-carotene (0.9 mg/p/d), the major contributors being kale, pumpkin and mango. beta-Cryptoxanthin (0.1 mg/p/d) was mostly supplied by orange, tangerine and papaya"(87.4% of its intake). Lycopene (0.7 mg/p/d) was found only in guava, watermelon and tomato. Lutein (0.8 mg/p/d), violaxanthin and neoxanthin (0.6 and 0.2 mg/p/d, respectively), were mainly supplied by green leafy vegetables and beta-carotene (0.16 mg/p/d) and zeaxanthin (0.06 mg/p/d) by a small number of foods.

    Nutrient Intake of Women 3 Years After Roux-en-Y Gastric Bypass Surgery
    (Springer, 2012-10-01) Torres Rossi, Rosana Gomes de; Amaral dos Santos, Maria Tereza; Suano de Souza, Fabiola Isabel [UNIFESP]; Aquino, Rita de Cassia de; Sarni, Roseli Oselka Saccardo [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP); Univ Sao Judas Tadeu
    Nutritional deficiencies, especially micronutrient deficiencies, can occur in obese individuals. Surgical treatment may aggravate or cause these deficiencies, depending on the type of procedure, food intake and the use of multivitamins, minerals or other supplements. the objective of the study was to evaluate the nutrient intake of women who had undergone Roux-en-Y gastric bypass (RYGB) surgery.A cross-sectional, controlled study was conducted among 44 women after RYGB (operated-group, OG; mean years post-operation = 3.4) and a control group of 38 healthy women (non-operated group, NOG) matched by age and economic condition. the women reported their dietary intake using a 4-day record. the Dietary Reference Intakes was used as a reference.The macronutrient contributions to dietary energy intake presented an acceptable distribution for proteins and carbohydrates. Lipid intake was high among women in the OG and the NOG (43.2 and 55.3 %, respectively). in the evaluation of micronutrients, a statistically significant difference was observed between the groups for iron, zinc and vitamins B1 and B12. Both groups were at high risk for inadequate calcium intake, and the OG was at risk for inadequate zinc, iron and vitamin B1 intake.The nutrient intake of women who had undergone RYGB is very similar to that of non-operated women, with the exception of a reduced intake of iron, zinc and vitamins B1 and B12, which may be due to the difficulty of consuming meat and a balanced diet. the findings of this study emphasize the importance of appropriate nutritional intervention and the regular use of multivitamin and mineral supplements for these patients.

    Nutritional risk among Brazilian children 2 to 6 years old: A multicenter study
    (Elsevier B.V., 2013-02-01) Bueno, Milena Baptista; Fisberg, Regina Mara; Maximino, Priscila [UNIFESP]; Rodrigues, Guilherme de Padua; Fisberg, Mauro [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP); Danone Res
    Objective: To estimate the nutritional risk in children 2 to 6 y old.Methods: the sample consisted of 3058 children enrolled in public and private schools in nine Brazilian cities. the assessment of nutrient intake was based on 1-d data combining direct individual weighing of foods and a food diary. A second evaluation of food consumption was conducted in a subsample to estimate the usual intake.Results: There was low prevalence of inadequate intake of vitamin B6 (<0.001%), riboflavin (<0.001%), niacin (<0.001%), thiamin (<0.001%), folate (<0.001%), phosphorus (<0.1%), magnesium (<0.1%), iron (<0.5%), copper (<0.001%), zinc (<0.5%), and selenium (<0.001%). However, 22% of children younger than 4 y and 5% of children older than 4 y consumed fiber quantities larger than the adequate intake. Approximately 30% of the sample consumed more saturated fat than recommended. the prevalence of inadequate vitamin E intake ranged from 15% to 29%. More than 90% of the children had an inadequate vitamin D intake. in children older than 4 y, the prevalence of inadequate calcium intake was approximately 45%. Sodium intake was higher than the upper intake level in 90% of children younger than 4 y and 73% of children older than 4 y.Conclusions: the prevalence of inadequate dietary intake was low for most nutrients. However, fiber, calcium, and vitamin D and E intakes were lower than recommended. Moreover, children consumed large amounts of sodium and saturated fat. (C) 2013 Elsevier Inc. All rights reserved.
