Comparative effects of whey and casein proteins on satiety in overweight and obese individuals: A randomized controlled trial

Background/Objective: Dairy protein seems to reduce appetite by increasing satiety and delaying the return of hunger and subsequently lowering energy intake compared with fat or carbohydrate. The aim of this study was to compare the effect of whey with that of casein proteins on satiety in overweight/obese individuals. Methods/Subjects: This was a randomized, parallel-design 12-week-long study. Seventy subjects with a body mass index between 25 and 40 kg/m2 and aged 18–65 years were randomized into one of three supplement groups: glucose control (n=25), casein (n=20) or whey (n=25) protein. Before commencing the study, at weeks 6 and 12 of the treatment, a Visual Analogue Scale (VAS) was used to measure subjective sensations of appetite before lunch and before dinner. Results: Rating for VAS (mm) at 6 and 12 weeks showed significantly higher satiety in the whey group compared with the casein (P=0.017 and P=0.025, respectively) or control (P=0.024 and P=0.032, respectively) groups when measured before lunch. Similarly, at 6 and 12 weeks, the score for fullness was also significantly higher in the whey group compared with both casein (P=0.038 and P=0.022, respectively) and control (P=0.020 and P=0.030, respectively) groups. However, these short-term effects on satiety from dairy whey proteins did not have any long-term effects on energy intake or body weight over 12 weeks compared with casein. Conclusions: Collectively, whey protein supplementation appears to have a positive and acute postprandial effect on satiety and fullness compared with casein and carbohydrate supplementation in overweight and obese individuals

Knowledge of Flemish paediatricians about children's oral health – results of a survey

AbstractObjective: To examine the knowledge paediatricians have about oral health in children.Methods: A questionnaire on oral health knowledge was mailed to all members of the Flemish Paediatric Association representing 350 out of 676 Flemish paediatricians. Questions concerned timing of the first dental visit, effects of thumb sucking, fluoride supplements, trauma, fluorosis, mutans streptococci and caries, prevention of dental caries, nursing bottle caries and use of sealants.Results: Two hundred seventy-six questionnaires (79%) were returned. Of the respondents, 71% said they have had some training on dental topics, and most rely on information brochures to be informed on dental subjects. Parents frequently questioned paediatricians about dental eruption. Paediatricians stated that the first dental visit should be scheduled at the age of 3. Eighty-three percent of the paediatricians stated that thumb sucking was harmful to dentition; 7% regularly prescribed fluoride supplements. Knowledge about fluorosis was moderate. Paediatricians judged community water fluoridation and tooth brushing after consuming erosive drinks as effective. The efficacy of dairy products was underrated. Seventy-three percent of the paediatricians were aware of nursing bottle caries, whereas only 39% were familiar with fissure sealing.Conclusion: Initiatives are needed to improve knowledge about oral health of physicians involved in preventive health care of children.info:eu-repo/semantics/publishe

Bioactive Substances of Animal Origin

Animals are rich sources of bioactive compounds that exhibit a variety of biological functions on human health. These bioactive molecules can be either essential to the animals’ living or only produced integrally of more importance to other organisms. Over the past decades, an ever-growing number of natural compounds of animal origins have been extracted, identified, and applied as dietary or therapeutic supplements, which prevent, alleviate, or treat diverse diseases and associated symptoms. Some well-known examples are animal-derived polyunsaturated fatty acids and polysaccharides. Once consumed via animal food intake or supplementation, the ubiquitous chemical structures of these bioactives allow them to be either the substrates for important biomolecule synthesis or the modulators affecting the structure and function of organs and tissues. In addition to nutritional and medical potentials, some animal-derived bioactives have wide applications in the food, biotechnological, and agricultural fields. This chapter provides a comprehensive review of the ten types of animal-derived bioactive compounds, mainly focusing on their sources, chemistry, and biological functions
