A pesquisa visou avaliar a ingestão de leite e substitutos, o hábito do desjejum e a percepção qualitativa do desjejum após o ingresso na instituição dos estudantes universitários de Nutrição da Universidade Federal do Triângulo Mineiro (UFTM), Uberaba (Minas Gerais). A amostra foi constituída por 111 estudantes, do primeiro ao oitavo semestre, de ambos os gêneros, com média de idade de 21 anos. A análise da ingestão alimentar foi feita pelo Questionário Semi-Quantitativo de Frequência Alimentar (QSQF) e perguntas sobre o hábito e consumo do desjejum. Os resultados mostraram que 37% dos estudantes ingeriam de 3 ou mais porções de leite e/ou substitutos diariamente e em relação ao hábito do desjejum, (60,36%) dos estudantes realizavam todos os dias. Na auto-avaliação do desjejum 46% classificaram como "bom" e 34,2% como "regular" e quanto as modificações alimentares ao ingressar na Universidade, 53,1% identificaram que houve mudança e, dentre estes, 54,2% classificaram como benéfica. Nesta pesquisa foram identificados bons hábitos entre os estudantes. Análises que envolvam os estudantes, vinculados à informação nutricional, tornam-se valiosas por fazerem parte da classe de futuros multiplicadores da área da saúde.Palavras-chave: estudantes universitários, hábito do desjejum, leite e substitutos. Assessment on milk intake and its substitutes: eating habits in breakfast of College students majoring in NutritionThe research aimed to evaluate the ingestion of milk and its substitutes, eating habits in breakfast, and the qualitative perception of students after their admission in the Nutrition Course at the Federal University of Triângulo Mineiro (UFTM), Uberaba (Minas Gerais). The sample consisted of 111 students from freshman to senior years, both genders, with an average age of 21. The diet ingest analysis was done by the Feed Frequency SemiQuantitative Questionnaire (acronym in Portuguese, QSQF) and also by open questions regarding breakfast habits and consumption. The results showed that 37% of the students ate up to 3 or more portions of milk and\or substitutes daily. In regard of breakfast habits, a great number of students (60.36%) specified their diet for daily breakfast. In the breakfast self-assessment 46% of the students classified as "good" and 34.2% as "regular". For dietary changes after entering university, 53.1% of the students identified changes in their eating habits, in which 54.2% among them classified such changes as beneficial. In this research, there was a positive factor related to eating habits among college students. Analysis involving students with nutritional information, become valuable once they will contribute with their knowledge in the health field.

Objectives To evaluate the additional effect of whey protein supplementation (WPS) to the physical-exercise training on bone resorption in postmenopausal women. Methods In a prospective, controlled study, 38 postmenopausal women aged 50 to 70 years, were randomized into two groups: with WPS (n = 19) and without WPS (n = 19, control) intervention. The study included amenorrheic women (above 12 months) with normal bone mineral density (T-score ≥ −1.0 SD) not taken bone-related medicines, and practitioners of a physical exercise protocol involving combined walking/jogging and academy/resistance exercises performed under professional supervising, three times a week. Together, there was a weekly dietary counseling along with a daily supplementation of either 25 g of protein (WPS) or placebo. Food intake (24-hour recall), anthropometric, general biochemistry, plasma hormones and bone resorption marker: serum C-terminal cross-linked N-telopeptides of type-I collagen (s-CTX) assessments were undertaken at baseline and after 20-wk intervention. Statistical analysis of the data (P < 0.05) was performed by using a time-repeated measures (ANOVA) followed by the Tukey multiple comparison test adjusted for group x moment interaction, or by gamma distribution (asymmetric variables). Results The groups were anthropometric and biochemical homogeneous, at baseline and after the intervention. Both groups increased similarly the intake of energy and lipids. However, only WPS significantly increased the intake of protein, calcium, phosphates and magnesium, as well as leucine, isoleucine and valine. From a similar baseline plasma values of s-CTX, calcium, phosphorus, alkaline phosphatase and parathormone, only s-CTX responded significantly to the intervention, being reduced in both groups (-34% and −15.2%), statistically significant in the control(non-WPS) group (P = 0.016). Conclusions The reduced plasma marker of bone resorption marker was observed in post-menopause women submitted to a 20-wk lifestyle-modification protocol with physical exercises, independently to the whey protein supplementation.
