Filter by:Consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. This shift is driven by environmental and health factors. However, the consequences of such a transition on muscle mass still remains to be explored. This is of particular importance in the older population, where the age-related reduction in muscle mass and strength is highly prevalent. Adequate dietary intake, specifically protein intake, is a well-known strategy in promoting muscle mass in older adults. Plant-based foods are currently considered to be inferior to animal-based foods in their protein quality, and are therefore considered to be suboptimal for the maintenance of muscle mass at an older age. On the other hand, combining plant-based foods may improve the protein quality and thereby the anabolic properties of a vegan meal. Evidence regarding the anabolic properties of vegan diets in older adults is scarce. As such, the current study aims to assess 1) the effects of a 12-week self-composed vegan diet in comparison to an omnivorous diet on thigh muscle volume (TMV) in community-dwelling older adults and 2) the effect of a 12-week self-composed vegan diet combined with twice-weekly resistance exercise (RE) on TMV in comparison to a self-composed vegan diet without resistance exercise in community-dwelling older adults.
Following increased knowledge about climate change and how food production affects greenhouse gas emissions, the interest in vegetarian diets is increasing. In line with this, also vegan diet is becoming more common at all ages, including in young children. But the state of knowledge regarding the effect of this diet on children during infancy and early childhood has been poorly studied and existing literature consists to a large extent of case reports. With the main hypothesis that vegan diet from the introduction of complementary foods causes reduced bio availability of certain micronutrients important for development, the aim of this study is to examine dietary intake and development during the first years of life in a group of children eating vegan diet and compare with a reference group eating mixed diets. In an observational study, investigators plan to include 30 children before the age of 6 months during the years 2021-2026, where the parents have decided to offer their child only vegan food. The children are studied in comparison with a reference group of 30 matched cases regarding growth, nutritional status, and dietary intake. Data collection includes monthly dietary records and blood sample analyses and growth at 6, 12 and 24 months. At the age of 3, cognitive developmental assessment (WPSSI-IV) and an DEXA examination of body composition are performed. The study is expected to contribute to increased knowledge about the risk and benefits of vegan diets and thereby provide a better basis for future recommendations.
