O café é uma bebida muito consumida mundialmente, sendo apreciada pelas características sensoriais e estimulantes. Sua qualidade está associada a fatores, como a composição química dos grãos e seu processamento (torra e extração). O extrato de soja é uma bebida nutritiva e saudável, porém não faz parte do hábito alimentar da maioria dos brasileiros, devido ao sabor característico de beany flavor. O aumento de pessoas com restrições ao consumo de leite e seus derivados, levou a desenvolvimento uma bebida à base de extrato de café (EC) e extrato de soja (ES), semelhante ao clássico café com leite". A analise de aceitação sensorial levou a formulação de ES com 3% EC. A bebida foi submetida à liofilização e após o processamento realizou-se a caracterização físico-química e analise de minerais dos extratos puros e da bebida final.

Abstract This work aimed to evaluate the enzymatic hydrolysis of okara protein concentrate with respect to degree of hydrolysis (DH) in order to obtain a protein hydrolysate with high antioxidant capacity and aglycones isoflavone content. A central composite rotatable design was carried out to evaluate the influence of temperature (40 to 70°C), enzyme:substrate ratio (0.5 to 5.0%, g/100g protein) and pH (7.0 to 9.0) on DH. The optimal condition was 55°C, pH 9 and enzyme:substrate ratio of 5.0%, resulting a DH value of 35.5%. After protein hydrolysis at optimal condition, the antioxidant capacities of hydrolysate increased from 58.29 to 383.49 μM Trolox equivalent/g solids (ABTS method) and 2.41 to 15.32 μM Trolox equivalent/g solids (FRAP method) when compared with protein concentrate. The higher radical scavenging ability of hydrolysate was due to great amount of hydrophobic amino acids (34.92 g/100g protein). Moreover, the protein hydrolysate obtained under optimal condition had 3 times higher aglycone isoflavone content than non-hydrolyzed sample. These results showed that protein hydrolysis of okara could be an alternative approach to increase antioxidant activity and enrich aglycones isoflavone in this byproduct generated from soymilk industry.

Abstract Soymilk was produced from vegetable soybean and fermented by probiotics (Lactobacillus acidophilus La-5, Bifidobacterium animalis Bb-12) in co-culture with Streptococcus thermophilus. The composition of the fermented beverage and oligosaccharides content were determined. The effect of fructooligosaccharides and inulin on the fermentation time and viability of probiotic microorganisms throughout 28 days of storage at 5 °C were evaluated. The soymilk from vegetable soybeans was fermented in just 3.2 h, when pH reached 4.8. Fermentation reduced the contents of stachyose and raffinose in soymilk. Prebiotics had no effect on acidification rate and on viability of B. animalis and S. thermophilus in the fermented beverage. The viable counts of B. animalis Bb-12 remained above 108 CFU mL-1 in the fermented soymilk during 28 days of storage at 5 °C while L. acidophilus La-5 was decreased by 1 log CFU mL-1. The fermented soymilk from vegetable soybeans showed to be a good food matrix to deliver probiotic bacteria, as well as a soy product with a lower content of non-digestible oligosaccharides.

BACKGROUND/OBJECTIVE: There is intense interest in soy isoflavone as a hormone replacement therapy for the prevention of postmenopausal osteoporosis. A new kind of isoflavone-enriched whole soy milk powder (I-WSM) containing more isoflavones than conventional whole soy milk powder was recently developed. The aim of this study was to investigate the effects of I-WSM on bone metabolism in ovariectomized mice. MATERIALS/METHODS: Sixty female ICR mice individually underwent ovariectomy (OVX) or a sham operation, and were randomized into six groups of 10 animals each as follows: Sham, OVX, OVX with 2% I-WSM diet, OVX with 10% I-WSM diet, OVX with 20% I-WSM diet, and OVX with 20% WSM diet. After an 8-week treatment period, bone mineral density (BMD), calcium, alkaline phosphatase (ALP), tartrate-resistant acid phosphatase (TRAP) 5b, osteocalcin (OC), procollagen 1 N-terminal propeptide (P1NP), and osteoprotegenin (OPG) were analyzed. RESULTS: BMD was significantly lower in the OVX group compared to the Sham group but was significantly higher in OVX + 10% I-WSM and OVX + 20% I-WSM groups compared to the OVX group (P < 0.05). Serum calcium concentration significantly increased in the OVX + 10% and 20% I-WSM groups. Serum ALP levels were significantly lower in the OVX + 10% and 20% I-WSM groups compared to the other experimental groups (P < 0.05). OC was significantly reduced in the OVX group compared to the Sham group (P < 0.05), but a dose-dependent increase was observed in the OVX groups supplemented with I-WSM. P1NP and OPG levels were significantly reduced, while TRAP 5b level was significantly elevated in the OVX group compared with the Sham group, which was not affected by I-WSM (P < 0.05). CONCLUSIONS: This study suggests that I-WSM supplementation in OVX mice has the effect of preventing BMD reduction and promoting bone formation. Therefore, I-WSM can be used as an effective alternative to postmenopausal osteoporosis prevention.

However, folate production was strain-dependent and also dependent on the environmental conditions and on the vegetable substrate used. Passion fruit by-product presented the lowest folate concentration and was selected for the following experiments. Thus, the impact of the supplementation of soymilk with passion fruit by-product and/or commercial prebiotic fructooligosaccharides FOS P95 on the folate production by three St. thermophilus strains, as well as four probiotic Lactobacillus strains (LA-5, LGG, PCC, and RC-14) were evaluated. St. thermophilus ST-M6 and TH-4 produced the highest amounts of folate in all fermented soymilks. The concentration of the vitamin was also high when these strains grew in co-culture with LA-5 and LGG. Soymilk supplemented with both passion fruit by-product and FOS together presented the highest concentration of folate when fermented by the co-culture TH-4+LGG. This co-culture was selected to produce four fermented soy products (FSP). All FSP were bio-enriched with folate produced by the co-culture and the probiotic strain LGG remained always above 8 log CFU/mL until the end of the storage period (28 days at 4ºC). In contrast, the concentration of the vitamin was stable until day 14 then a slight decrease was observed at the end of the storage period. The FSP supplemented with both passion fruit by-product and FOS together may contribute with around 14% of the recommended daily intake for folate if consumed until day 14 of storage. During the in vitro simulated gastrointestinal conditions, the folate content of the digested FSP increased from 1.3 to 3.6-fold, especially at the small and large intestinal in vitro phases and the strain LGG was recovered. In contrast, St. thermophilus TH-4 was not recovered during the assay. Finally, the prebiotic potential of the bioactive compounds present in the fruit by-products was characterized. Fruit by-product water extracts (FWE) containing soluble fibres from fruit by-products were obtained through a hot-water extraction and were associated to phenolic compounds and showed antioxidant activity. The FWE (especially, orange and mango water extracts) presented an anti-inflammatory potential by decreasing the nitric oxide concentration produced in vitro by macrophages stimulated with lipopolisaccharides (LPS) from Salmonella Thyphymurium. The FWE (especially from mango) were able to stimulate the growth of the strains TH-4 and LGG, as well the folate production by these microorganisms when tested individually and in co-culture. The FWE also increased the adhesion of TH-4 and LGG to Caco-2 cells in an in vitro model. These results suggest a prebiotic potential of the fruit by-products evaluated and their potential towards increased folate production by the selected microorganisms. Therefore, the bio-enrichment of fermented soy products with folate produced by beneficial microorganisms is an alternative for the development of functional foods with high folate content. Additionally, fermentable bioactive compounds with functional and/or biological activity, such as soluble fibres associated to phenolic compounds with antioxidant activity, present in the fruit by-products, may act as potential prebiotic ingredients. These bioactive molecules may represent a potential natural alternative to synthetic drugs for the treatment of inflammatory processes
O objetivo deste trabalho foi avaliar o efeito de subprodutos vegetais, incluindo subprodutos do processamento de fruta (maracujá, laranja, acerola e manga) e de soja (okara) na produção de folatos de novo por microrganismos strater e probióticos para bioenriquecer um produto de soja fermentado. Na primeira etapa deste trabalho, o impacto da farinha de amaranto na produção de folatos pelos microrganismos também foi avaliado. Neste sentido, primeiramente, verificou-se o efeito desses subprodutos vegetais e da farinha de amaranto na capacidade de três cepas starter - Streptococcus thermophilus (ST-M6, TH-4 e TA-40) e 10 cepas probióticas (Lactobacillus (Lb.) acidophilus LA-5, Lb. fermentum PCC, Lb. reuteri RC-14, Lb. paracasei subsp. paracasei Lb. casei 431, Lb. paracasei subsp. paracasei F19, Lb. rhamnosus GR-1, and Lb. rhamnosus LGG, Bifidobacterium (B.) animalis subsp. lactis BB-12, B. longum subsp. longum BB-46, e B. longum subsp. infantis BB-02) em produzir folato utilizando um caldo MRS modificado. A maior parte dos microrganismos testados foi capaz de produzir folato. Entretanto, a produção foi considerada cepa-dependente e, também, dependente das condições ambientais e do tipo de subproduto vegetal empregado. O subproduto de maracujá apresentou a menor concentração de folato e, por isso, foi selecionado para os testes seguintes. Neste sentido, o impacto da suplementação do leite de soja com subproduto de maracujá e/ou com o prebiótico comercial fruto-oligosacarídeo FOS P95 na produção de folato pelas três cepas de St. thermophilus, bem como quarto cepas probióticas do gênero Lactobacillus (LA-5, LGG, PCC e RC-14), também foi avaliado. Em cultura pura, as cepas de St. thermophilus ST-M6 e TH-4 produziram grande quantidade de folato nas formulações de extrato de soja fermentados. A concentração da vitamina foi maior quando tais cepas se desenvolveram em co-cultura com LA-5 e LGG. Observou-se que o extrato de soja suplementado concomitantemente com subproduto de maracujá e FOS apresentou a maior quantidade de folato quando fermentado pela co-cultura TH-4+LGG. Esta co-cultura, portanto, foi selecionada para desenvolver os produtos fermentados de soja (PFS). Todas as formulações foram bioenriquecidas e a cepa LGG manteve-se viável por todo o período de armazenamento (28 dias a 4ºC). Entretanto, a concentração da vitamina manteve-se estável apenas até o dia 14, observando-se uma diminuição da quantidade de folato ao final do período de armazenamento. Constatou-se que o produto fermentado de soja suplementado concomitantemente com subproduto de maracujá e FOS pode contribuir com cerca de 14% da ingestão diária recomendada para folato se consumido até o dia 14 do armazenamento. Além disso, durante a simulação gastrointestinal in vitro, observou-se que a digestão aumentou de 1,3 a 3,6 vezes a concentração da vitamina incrementando, consideravelmente, a bioacessibilidade do folato, principalmente nas porções simuladas do intestino delgado e grosso do intestino e a cepa LGG foi recuperada. Entretanto, a cepa St. thermophilus TH-4 não foi recuperada durante o ensaio. Por fim, o potencial prebiótico de componentes bioativos presentes nos subprodutos de fruta foi caracterizado. Uma extração Hot Water foi conduzida, a fim de obter extratos aquosos de subprodutos de fruta ricos em fibras solúveis associadas a compostos fenólicos com atividade antioxidante. Observou-se, ainda, que tais extratos aquosos de subprodutos de fruta (laranja e manga) apresentaram potencial anti-inflamatório constatado pela diminuição da concentração de óxido nítrico produzido por macrófagos estimulados com lipopolissacarideo (LPS) de Salmonella Typhymurium in vitro. Além disso, os extratos aquosos de subprodutos de fruta (principalmente o extrato aquoso de subproduto de manga) foram capazes de estimular a multiplicação das cepas TH-4 e LGG, bem como a produção de folatos por estes microrganismos quando avaliados individualmente e em co-cultura. Adicionalmente, esses extratos aquosos de subprodutos de fruta aumentaram a adesao do TH-4 e do LGG a células Caco-2 em modelo in vitro. Neste sentido, os resultados sugerem um potencial prebiótico dos subprodutos de fruta testados, de modo a estimular, não somente o desenvolvimento dos microrganismos avaliados mas, principalmente, o potencial destes em produzir folatos na presença dos substratos vegetais testados. O bioenriquecimento dos produtos fermentados de soja com folatos produzidos por microrganismos benéficos emerge como alternativa de alimento potencialmente funcional com alto teor de folato. Adicionalmente, compostos bioativos fermentescíveis e com atividade biológica como, por exemplo, as fibras solúveis associadas a compostos fenólicos com atividade antioxidante, presentes nos subprodutos de fruta testados podem constituir potenciais ingredientes prebióticos, além de representarem uma possível alternativa natural para o tratamento de processos inflamatórios

ABSTRACT Objective: This study aimed to compare the intestinal absorption of iron and calcium between soy-based and cow's milk-based infant formulas in weanling rats. Methods: Twenty male Wistar rats, twenty-one days old on the first day of weaning, were used in this experiment, divided in two Groups, one Group was fed soy protein-based infant formula the other, cow's milk protein-based infant formula. During the study period (ten consecutive days) the animals received food and water ad libitum. Hematocrit and hemoglobin were evaluated on the first, fifth, and tenth days by the Wintrobe and cyanomethemoglobin methods. Feces and urine were collected, beginning on the fifth day, for three consecutive days. On the tenth day, hepatic iron content was also analyzed. Hepatic iron as well as fecal and urinary iron and calcium analyses were performed using an atomic absorption spectrophotometer. At thirty-one days of age, the animals were anesthetized with ketamine and xylazine and sacrificed by exsanguination via the vena cava. Results: The final concentration of hemoglobin in the group soy-based infant formula and milk-based infant formula were: 10.3±1.3g/dL and 10.9±1.0g/dL (p=0.310). The apparent absorption of iron and calcium, in that order, were: 73.4±10.2% and 70.2±9.5%; 97.2±0.7% and 97.6±1.0% (p=0.501; p=0.290). The apparent calcium retention was: 88.4% ±2.2 and 88.6±2.6% (p=0.848). Hepatic iron content was: 522.0±121.1mg/g and 527.8±80.5mg/g (p=0.907) . Conclusion: Intestinal iron and calcium absorption from soy-based infant formula is similar to that from milk-based infant formula in weanling rats.
RESUMO Objetivo: Este estudo objetivou comparar a absorção intestinal de ferro e cálcio entre fórmulas infantis à base de leite de vaca e de soja em ratos recém-desmamados. Métodos: Vinte ratos machos Wistar, com 21 dias de vida e no primeiro dia do desmame foram utilizados neste experimento, divididos em dois grupos: um alimentado com fórmula infantil à base de proteína de soja e o outro com fórmula infantil à base de proteína do leite de vaca. Durante o período de estudo (10 dias consecutivos), os ratos receberam dieta e água ad libitum. Hematócrito e hemoglobina foram mensurados no primeiro, quinto e décimo dia pelo método de Wintrobe e da cianometaemoglobina. As fezes e a urina foram recolhidas a partir do quinto dia durante durante três dias consecutivos. No décimo dia, o conteúdo de ferro hepático também foi analisado. O conteúdo de ferro hepático e a análise de ferro e cálcio nas fezes e na urina foram realizados utilizando espectrofotômetro de absorção atômica. Aos 31 dias de vida, os animais foram anestesiados com ketamina e xilasina e sacrificados por exsanguinação da veia vaca. Resultados: A concentração final de hemoglobina no grupo fórmula infantil à base de soja e fórmula infantil à base de leite de vaca foram 10,3±1,3g/dL e 10,9± 1,0g/dL (p=0,310), respectivamente. A absorção aparente de ferro e cálcio foi de: 73,4±10,2% e 70,2±9,5%, para o primeiro grupo; e 97,2±0,7% e 97,6±1,0%, para o segundo (p=0,501; p=0,290). A retenção aparente de cálcio foi: 88,4±2,2% e 88,6±2,6% (p=0,848). O teor de ferro hepático foi: 522,0±121,1µg/g e 527,8±80,5µg/g (p=0,907), respectivamente. Conclusão: A absorção intestinal de ferro e cálcio da fórmula infantil à base de soja é similar à da fórmula infantil à base de leite em ratos recém-desmamados.

Functional food intake has been highlighted as a strategy for the prevention of cardiovascular diseases by reducing risk factors. In this study, we compared the effects of oral treatment with soy milk and simvastatin on dyslipidemia, left ventricle remodeling and atherosclerotic lesion of LDL receptor knockout mice (LDLr-/-) fed a hyperlipidic diet. Forty 3-month old male LDLr-/- mice were distributed into four groups: control group (C), in which animals received standard diet; HL group, in which animals were fed a hyperlipidic diet; HL+SM or HL+S groups, in which animals were submitted to a hyperlipidic diet plus soy milk or simvastatin, respectively. After 60 days, both soy milk and simvastatin treatment prevented dyslipidemia, atherosclerotic lesion progression and left ventricle hypertrophy in LDLr-/- mice. These beneficial effects of soy milk and simvastatin were associated with reduced oxidative stress and inflammatory state in the heart and aorta caused by the hyperlipidic diet. Treatment with soy milk was more effective in preventing HDLc reduction and triacylglycerol and VLDLc increase. On the other hand, simvastatin was more effective in preventing an increase in total cholesterol, LDLc and superoxide production in aorta, as well as CD40L both in aorta and left ventricle of LDLr-/-. In conclusion, our results suggest a cardioprotective effect of soy milk in LDLr-/- mice comparable to the well-known effects of simvastatin.

OBJECTIVES: A lack of understanding in menopausal and postmenopausal women's (PMW) risk perception towards osteoporosis and breast cancer still exists, which is explored in this study. This information might allow health professionals to conduct interventions to improve health behaviors before menopause-related diseases are imminent. METHODS: Between 10 December 2015 and 31 January 2016, 573 menopausal or PMW were successfully interviewed on 17 questions, comprising separate sections for osteoporosis and breast cancer. The target respondents were menopausal or PMW aged 45 to 60 years, with no previous diagnosis of osteoporosis or breast cancer, who attended private clinics across Hong Kong for annual physical examination. RESULTS: Regarding menopausal issues, the top three concerns were osteoporosis and fracture (72%), breast cancer (44%), and sleep disorder/insomnia/headache (40%). Among 314 respondents (55%) who tried to prevent osteoporosis, 74% of them began to do it after they were 40 years old. On the other hand, 65% of respondents never had a bone density test. For respondents who said “I'm too young, so I don't need to check”, their mean age was 52 years old. Ninety percent of respondents mistakenly believed that regular breast examination, regular breast massage, drink soy milk, or vaccine can prevent breast cancer. CONCLUSIONS: This survey revealed osteoporosis and breast cancer as the top concerns among menopausal and PMW in Hong Kong. Inadequate health behaviors and misconceptions still exist despite widespread health education in the recent years.

OBJECTIVES: This study was designed to find out factors that are needed to be improved for the Buddhist training environment of Sramanera·Sramanerika monks, who have been newly adapted for their life style after becoming a monk, and to provide basic data for the development of the standard diet in Buddhist temples. METHODS: A self-administered questionnaire was applied to 365 Sramanera·Sramanerika monks at 11 Buddhist monk universities. The questionnaire was designed to investigate their dietary habits, dietary evaluation, satisfaction of food service, and food preferences. RESULTS: The study population consisted of 52.6% men, and 47.4% women. The subjects who had a vegetarian diet before joining the Buddhist priesthood were 27.7% women, and 13.5% men (p<0.01). 42.2% of the total subjects felt that they are healthy now and 19.4% felt weak. The most difficulty of dieting adaptation as soon as entering the priesthood was the strict diet rules (42.9%). The subjects considered health or nutrition (40.0%) highly when having meals. 94.8% women, 84.1% men ate breakfast every day (p<0.001). Women (55.4%) frequently ate snacks more than men (26.6%) (p<0.001). The results of the dietary evaluation indicated that the intake of milk, soy milk or dairy products and beans or tofu received lower than 3 points and women had lower point result than men (p<0.001). Foods with higher preference were grilled mushrooms, grilled laver, miso stew, sweet and sour mushrooms, steamed tofu with seasoning. CONCLUSIONS: Women were more interested in their health than men but they also required to improve the nutritional eating habits. It appeared that the lower intake rates of the calcium containing food (milk and dairy), and proteins (beans and tofu) could result in nutritional imbalance. Therefore, it is necessary to offer food based on the standard menu plan with consideration given to their food preferences in order to maintain their health and desirable dietary habits.

PURPOSE: This study was performed to examine associations of intakes of milk and dairy products, pulses, and soy foods with bone health in Koreans aged 50 yr and older. METHODS: A total of 3,201 men and 3,581 women aged 50 yr and older who participated in the 2008~2011 Korea National Health and Nutrition Examination Survey were grouped by sex and age groups of 50~64 yr and 65 yr and older. Subjects within each sex and age group were divided into three bone health groups: normal, osteopenia, and osteoporosis groups based on bone mineral density. Intakes of nutrients and foods derived from 24-hour recall data were compared among three bone health groups. Associations between intake frequencies of foods, including milk, yogurt, tofu, or soy milk, and osteoporosis risk were evaluated based on confounding risk factor-adjusted logistic regression. RESULTS: Calcium intake was in the order of normal, osteopenia, and osteoporosis in men (p < 0.01) and women (p < 0.05) aged 50~64 yr as well as in men aged 65 yr and older (p < 0.001). In women aged 50~64 yr, intake of milk and dairy products was lower in the osteoporosis group (p < 0.01) as compared with the osteopenia group. Intake of pulses or tofu was not significantly different among bone health groups. Odds ratio (OR) for milk intake frequency (≥ 2 times/week) compared to intake frequency less than 1 time/month was 0.45 (95% CI 0.24~0.85, p for trend = 0.022) in men aged 65 yr and older. The OR for yogurt intake frequency (1 time/month~1 time/week) was 0.47 (95% CI 0.30~0.73, p for trend = 0.019) in women aged 50~64 yr. Intake frequency of tofu or soy milk was not associated with reduced risk of osteoporosis in all groups. CONCLUSION: Dairy food intake was significantly associated with bone health, and its effect was sex- and age group-specific, whereas soy food intake was not. Dietary intervention to prevent osteoporosis would be effective for women aged 50~64 yr old and for men aged 65 yr and older.

PURPOSE: Breast-feeding is recommended to prevent allergies, particularly in high-risk infants, but the evidence of protective effects that breast-feeding has on food allergy (FA) remains elusive. The aim of this study was to investigate risk factors of FA and the association between breast-feeding and FA symptoms/food sensitization (FS) in children with atopic dermatitis under 2 years of age. METHODS: We reviewed the medical records of 384 children with atopic dermatitis under 2 years of age who visited our pediatric allergy clinic from March 1, 2009 through December 31, 2014. Symptoms of FA, feeding type, and family history of allergic disease were assessed. Laboratory tests were conducted, including serum total IgE, eosinophil (%), serum 25-hydroxyvitamin D, and specific IgE to egg white, milk, soy, peanut, and wheat. RESULTS: Subjects were divided into 3 groups based on FA symptoms and evidence of sensitization: The FA symptom group (n=240), no symptom group (n=53) and no FS group (n=91). The FA symptom group had a higher log total IgE level (2.0 vs. 1.3, P<0.001) and eosinophil (%) (7.0% vs. 4.7%, P=0.001) than the no FA symptom group. In multivariate analysis, breast-feeding was associated with FS (adjusted odds ratio [aOR], 2.43; 95% confidence intervals [CI], 1.03-5.74) but was not associated with FA symptoms (aOR, 0.65; 95% CI, 0.23-1.83). CONCLUSION: Breast-feeding may increase the risk of FS, but not immediate-type FA symptoms in children with atopic dermatitis.

OBJECTIVE: To compare body growth, weight, and fecal moisture in recently weaned rats fed exclusively on infant soy formula and soy-based beverage. METHODS: Three similar groups were formed (n = 10/group) consisting of weanling Wistar rats, maintained in metabolic cages. One group was fed soy protein-based beverage, another with soy-based infant formula, and another with cow's milk infant formula (control group). Water and diet were offered ad libitum. Body weight and length were measured. Stool was collected for three consecutive days. RESULTS: Weight and length were lower (p = 0.001; p = 0.001) in the groups receiving soy protein-based beverage (73.16 ± 5.74 g; 23.94 ± 1.04 cm) and soy-based formula (71.11 ± 5.84 g; 24.74 ± 0.60 cm) in relation to the group receiving cow's milk formula (84.88 ± 9.75 g; 26.01 ± 0.91 cm). Fresh fecal weight was greater (p < 0.001) in the soy-based beverage (3.44 ± 0.48 g) than in the soy-based formula (0.79 ± 0.20 g) and cow's milk-based formula (0.42 ± 0.17 g). Fecal moisture was higher (p < 0.001) in the group receiving soy protein-based beverage (47.28 ± 9.02%) and soy-based formula (37.21 ± 13.20%) than in the group receiving cow's milk formula (22.71 ± 10.86%). CONCLUSION: The growth of rats fed soy protein-based beverage and soy-based formula was lower than those fed cow's milk-based formula. The soy protein-based beverage resulted in significant increase in fecal weight and moisture. .
OBJETIVO: Comparar o crescimento corporal, o peso e a umidade das fezes de ratos recém-desmamados alimentados exclusivamente com fórmula infantil de soja e com bebida de extrato de soja. MÉTODOS: Constituíram-se três grupos similares (n = 10/grupo) de ratos machos Wistar recém-desmamados, mantidos em gaiolas metabólicas. Um grupo foi alimentado com bebida de extrato de soja, outro com fórmula infantil de soja e o outro com fórmula infantil de leite de vaca (grupo controle). Água e dieta foram oferecidas ad libitum. Foram mensurados o peso e o comprimento corporal. Fezes foram coletadas durante três dias consecutivos. RESULTADOS: Peso e comprimento foram menores (p = 0,001; p = 0,001) nos grupos com bebida de extrato de soja (73,16 ± 5,74 g; 23,94 ± 1,04 cm) e fórmula infantil de soja (71,11 ± 5,84 g; 24,74 ± 0,60 cm) em relação ao grupo de fórmula infantil de leite de vaca (84,88 ± 9,75 g; 26,01 ± 0,91 cm). O peso fresco fecal foi maior (p < 0,001) na bebida de extrato de soja (3,44 ± 0,48 g) do que com as fórmulas infantis de soja (0,79 ± 0,20 g) e de leite de vaca (0,42 ± 0,17 g). A umidade fecal foi maior (p < 0,001) na bebida de extrato de soja (47,28 ± 9,02%) e fórmula infantil de soja (37,21 ± 13,20%) do que na fórmula infantil de leite de vaca (22,71 ± 10,86%). CONCLUSÃO: O crescimento de ratos alimentados com bebida de soja e fórmula infantil de soja foi menor do que os alimentados com fórmula com proteína do leite de vaca. A bebida à base de extrato de soja proporcionou aumento expressivo do peso e da umidade fecal. .

PURPOSE: Soy-based formulas are widely used as dairy substitutes to treat milk allergy patients. However, reactions to soy have been reported in a small proportion of patients with IgE-mediated milk allergies. The aim of this work was to explore whether P34, a mayor soybean allergen, is involved in this cross-reactivity. METHODS: In vitro recognition of P34 was evaluated by immunoblotting, competitive ELISA and basophil activation tests (BAT) using sera from allergic patients. In vivo cross-reactivity was examined using an IgE-mediated milk allergy mouse model. RESULTS: P34 was recognized by IgE antibodies from the sera of milk allergic patients, casein-specific monoclonal antibodies, and sera from milk-allergic mice. Spleen cells from sensitized mice incubated with milk, soy or P34 secreted IL-5 and IL-13, while IFN-gamma remained unchanged. In addition, the cutaneous test was positive with cow's milk proteins (CMP) and P34 in the milk allergy mouse model. Moreover, milk-sensitized mice developed immediate symptoms following sublingual exposure to P34. CONCLUSIONS: Our results demonstrate that P34 shares epitopes with bovine casein, which is responsible for inducing hypersensitivity symptoms in milk allergic mice. This is the first report of the in vivo cross-allergenicity of P34.

<p><b>INTRODUCTION</b>Obesity is a major modifiable risk factor associated with most chronic diseases. The aim of this study was to determine the prevalence of obesity, and its associated risk factors, among apparently healthy Chinese adults in a Malaysian suburban village.</p><p><b>METHODS</b>This was a cross-sectional study conducted among the Chinese residents in Seri Kembangan New Village, Klang Valley, Selangor, Malaysia. Convenience sampling was used for the selection of participants. Body weight, height, waist and hip circumferences, and blood pressure were measured. Fasting venous plasma was drawn for the measurement of fasting glucose level and lipid profile. Data on sociodemographic factors, dietary habits, physical activity, perceived stress level and sleep duration were collected using interviewer-administered, pretested and validated questionnaires.</p><p><b>RESULTS</b>Among the 258 Chinese residents (mean age 41.4 ± 10.0 years) recruited, the prevalence of obesity was 40%. The obese participants had significantly higher mean blood pressure, and triglyceride and fasting plasma glucose levels than the non-obese participants (p < 0.05). The obese participants also had a significantly lower high-density lipoprotein cholesterol level than the non-obese participants. Logistic regression analysis showed that drinking soy milk (adjusted odds ratio [OR] 0.447; 95% confidence interval [CI] 0.253-0.787; p < 0.05) and the perception that a balanced diet consists mainly of vegetables (adjusted OR 0.440; 95% CI 0.215-0.900; p < 0.05) were associated with a reduced risk of obesity. The risk of obesity was higher in younger participants (adjusted OR 2.714; 95% CI 1.225-6.011; p < 0.05).</p><p><b>CONCLUSION</b>The prevalence of obesity was high among the apparently healthy suburban Chinese. Our findings suggest that soy milk consumption and the perception that a balanced diet consists mainly of vegetables are associated with a lower risk of developing obesity in this population.</p>

The purpose of this study was to determine if Theory of Planned Behavior (TPB) variables predict soy milk intake in a sample of WIC participants in 2 Illinois counties (n = 380). A cross-sectional survey was used, which examined soy foods intake, behavioral beliefs, subjective norms, motivation, and intention. Soy product intake was low at both sites, and many participants (40%) did not know that soy milk was WIC approved. Most (> 70%) wanted to comply with their health care providers, but didn't know their opinions about soy milk (50-66%). Intention was significantly correlated with intake (0.507, P < or = 0.01; 0.308, P < or = 0.05). Environmental beliefs (0.282 and 0.410, P < or = 0.01) and expectancy beliefs (0.490 and 0.636, P < or = 0.01) were correlated with intention. At site 1, 30% of the variance in intention to consume soy milk was explained by expectancy beliefs and subjective norm beliefs (P < 0.0001); at site 2, 40% of the variance in intention was explained by expectancy beliefs. The TPB variables of expectancy beliefs predicted intention to consume soy milk in WIC participants. Therefore, knowing more about the health benefits of soy and how to cook with soy milk would increase WIC participants' intention to consume soy milk. Positive messages about soy milk from health care providers could influence intake.

BACKGROUND/OBJECTIVES: The objective of the study was to provide useful insights into plain water intake of Korean adults according to life style, anthropometric, and dietary characteristics. SUBJECTS/METHODS: The data from the 2008-2010 Korea National Health and Nutrition Examination Survey were used. The subjects were 14,428 aged 20-64 years. Water intake was estimated by asking the question "How much water do you usually consume per day?". Dietary intake was estimated by 24-hour dietary recall. A qualitative food frequency questionnaire including 63 food items was also administered. RESULTS: The mean plain water intake for men and women were 6.3 cup/day and 4.6 cup/day, respectively. Plain water intake increased as lean body mass, waist circumference, and body mass index levels increased, except for percentage of body fat. As energy and alcohol intakes increased, plain water intake increased. As total weight of food intake and total volume of food intake increased, plain water intake increased. Plain water intake increased as consumption of vegetables increased. Plain water intake increased as frequencies of green tea, alcoholic drink, and all beverages were increased in men. Plain water intake increased with increased frequencies of green tea, milk, soy milk, and alcoholic drink and decreased frequencies of coffee and soda in women. CONCLUSIONS: Our results suggest that persons who had a higher waist circumference or lean body mass and women with higher BMI consumed more plain water. The persons eating high quality diet, or the persons who had more vegetables, green tea, milk, soy milk, or alcoholic drink consumed more plain water.

Soy milk (SM) is widely consumed worldwide as a substitute for cow milk. It is a source of vitamins, carbohydrates and sugars, but its capacity to preserve cell viability has not been evaluated. The purpose of the present study was to investigate the efficacy of SM to maintain the viability of human fibroblasts at short periods compared with different cow milks. Human mouth fibroblasts were cultured and stored in the following media at room temperature: 10% Dulbecco's Modified Eagle Medium (DMEM) (positive control group); long shelf-life ultra-high temperature whole cow milk (WM); long shelf-life ultra-high temperature skim cow milk (SKM); powdered cow milk (PM); and soy milk (SM). After 5, 15, 30 and 45 min, cell viability was analyzed using the MTT assay. Data were analyzed statistically by the Kruskal-Wallis test with post-analysis using the Dunn's method (α=0.05). SKM showed the lowest capacity to maintain cell viability in all analyzed times (p<0.05). At 30 and 45 min, the absorbance levels in control group (DMEM) and SM were significantly higher than in SKM (p<0.05). Cell viability decreased along the time (5-45 min). The results indicate that SM can be used as a more adequate storage medium for avulsed teeth. SKM was not as effective in preserving cell viability as the cell culture medium and SM.
O leite de soja (LS) é largamente consumido em todo o mundo como substituto para o leite bovino. Este é uma fonte de vitaminas, carboidratos e açúcares, mas a sua capacidade para preservar a viabilidade celular não foi avaliada. A finalidade do estudo foi investigar a eficácia do LS em manter a viabilidade de fibroblastos humanos em períodos curtos em comparação com diferentes leites bovinos. Fibroblastos de boca humanos foram cultivados e armazenados nos seguintes meios à temperatura ambiente: 10% de meio Dulbecco's Modified Eagle (DMEM) (grupo controle positivo); leite bovino integral longa vida (LI); leite bovino desnatado longa vida - LD; leite em pó - LP; leite de soja - LS. Depois de 5, 15, 30 e 45 min, a viabilidade celular foi analisada usando o método de MTT. Os dados foram analisados estatisticamente pelo teste de Kruskal-Wallis e posteriormente usando o método de Dunn (α=0,05). O grupo LD apresentou a menor capacidade para manter a viabilidade celular em todos os tempos analisados (p<0,05). Aos 30 e aos 45 min, os níveis de absorbância no grupo controle (DMEM) e LS foram significativamente maiores que no grupo LD (p<0,05). A viabilidade celular diminuiu ao longo do tempo (5-45 min). Os resultados indicaram que LS pode ser usado como meio de armazenamento mais adequado para dentes avulsionados. LD não foi eficaz na preservação da viabilidade das células como o meio de cultura de células e o LS.
