    Adolescentes modelos de passarela: como é o consumo alimentar deste grupo?
    (Sociedade de Pediatria de São Paulo, 2010-12-01) Rodrigues, Alexandra Magna [UNIFESP]; Cintra, Isa de Pádua [UNIFESP]; Santos, Luana Caroline dos; Martini, Ligia Araújo [UNIFESP]; Mello, Marco Tulio de [UNIFESP]; Fisberg, Mauro [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)
    OBJECTIVE: To evaluate the adequacy of energy, macro and micronutrients intake in adolescent runway models. METHODS: This cross-sectional study enrolled 33 models and 33 non-models, with ages ranging from 15 to 18 years, paired by age and body mass index (BMI). Food intake was evaluated by a three-day food record. The average energy values were estimated in kcal, the proportional values of macronutrients as to the total caloric value of the consumed diet were also calculated, as well as the mean/medium values of the following micronutrients: calcium, iron, zinc, phosphorus, magnesium, folate, vitamin D, vitamin C, vitamin A and vitamin E. RESULTS: Among the studied adolescents, 24% presented BMI below the minimum values for the age. Mean energy intake was lower among the models compared to non-models (1,480.93±582.95 versus 1,973.00±557.63 kcal) (p<0.05). The fat intake, higher than the recommended, was similar in both groups (30.3% in models and 36.4% of the non-model adolescents - p>0.05). The inadequate consumption of micronutrients such as calcium, iron, zinc, magnesium, phosphorus, liposoluble vitamins, folate and ascorbic acid was observed in both groups. CONCLUSIONS: The low energy intake (kcal) among models and the insufficient intake of minerals and vitamins are red flags for model agencies to be more committed to the health of these adolescents, ensuring that they get nutritional and medical follow-up.

    Infant formula iron dialysability related to other nutrients
    (Elsevier B.V., 2005-05-01) Nogueira, Cristiane de Souza [UNIFESP]; Colli, Celia; Amancio, Olga Maria Silverio; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)
    The dialysable iron in relation to total iron, to protein sources, to calcium, magnesium, copper, zinc, and vitamin C of 17 infant formulas, from four different multinational companies were analyzed. Total iron, calcium, magnesium, copper, and zinc were determined by atomic absorption spectrophotometry. the dialysable iron was determined. the considered vitamin C concentration was that declared on the labels. There was no significant statistical relationship between total iron and dialysable iron (P = 0.54, r = 0.09) when considered separately. When analyzed considering protein sources, this relationship was shown to be inversely proportional to protein hydrolysate (P = 0.03, r = -0.72), and soy protein (P = 0.02, r = -0.93). the percentage of dialysable iron was significantly greater from the protein hydrolysate (P < 0.01). the dialysable iron showed a negative correlation with calcium (P < 0.05, r = -0.61). in conclusion, the infant formulas whose protein sources are casein and casein plus whey protein should present Ca:Fe and Fe:vitamin C ratios that allow considerable iron dialysability.

    Keloids: a new challenge for nutrition
    (Wiley-Blackwell, 2010-07-01) Bersch-Ferreira, Ângela Cristine [UNIFESP]; Hochman, Bernardo [UNIFESP]; Furtado, Fabianne [UNIFESP]; Bonatti, Silvilena [UNIFESP]; Ferreira, Lydia Masako [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Keloids are the result of a dysfunctional scarring process that leads to excessive deposition of extracellular matrix in susceptible individuals, causing them physical, psychological, and social discomfort. Many studies have investigated various aspects of keloid physiopathology; however, the relationship between dietary components and keloids has not received much attention. the present literature review was conducted to examine the available evidence related to the relationships between nutrition/nutrients and keloids. Findings from in vitro and in vivo studies indicate possible associations exist between keloids and fatty acids, soluble fibers, and phytochemicals. However, these relationships have not been fully explored and new studies need to be carried out before any efficient diet-based therapy can be prescribed for the prevention and treatment of keloids.
