Rationale: The goal of the PROVE (Protein enriched vegan products to fight malnutrition) project is to innovate the assortment of plant-based energy and protein enriched products for dietary treatment of (risk of) malnutrition. We aimed to explore preferences of dietitians for plant-based products in the treatment of malnutrition.Methods: In this design-based research project, the Double Diamond model was applied. Contextual interviews were performed with 9 dietitians experienced in treating clients using a vegan diet (1 omnivore, 3 flexi-vegetarian, 1 vegetarian, 1 pescetarian, 3 flexi-vegan). Interviews focused on preferences regarding product type, size, nutrients, taste, packaging, price. Affinity mapping was used to code and analyze the transcripted interviews. The results were summarized into concept products.Results: Four product concepts were developed that represent preferences of dietitians for a plant-based energy and protein enriched product for clients with (risk of) malnutrition. Overall, pea or soy were preferred as a protein source and addition of vitamins and minerals was not preferred.Conclusion: Preferences of dietitians for plant-based protein and energy rich products for patients with risk of malnutrition largely vary. Within PROVE, we will enrich these results with patient perspectives, as basis to develop and deliver plant-based energy and protein enriched products for treatment of (risk of) malnutrition.

INTRODUCTION: Sufficient high quality dietary protein intake is required to prevent or treat sarcopenia in elderly people. Therefore, the intake of specific protein sources as well as their timing of intake are important to improve dietary protein intake in elderly people.OBJECTIVES: to assess the consumption of protein sources as well as the distribution of protein sources over the day in community-dwelling, frail and institutionalized elderly people.METHODS: Habitual dietary intake was evaluated using 2- and 3-day food records collected from various studies involving 739 community-dwelling, 321 frail and 219 institutionalized elderly people.RESULTS: Daily protein intake averaged 71 ± 18 g/day in community-dwelling, 71 ± 20 g/day in frail and 58 ± 16 g/day in institutionalized elderly people and accounted for 16% ± 3%, 16% ± 3% and 17% ± 3% of their energy intake, respectively. Dietary protein intake ranged from 10 to 12 g at breakfast, 15 to 23 g at lunch and 24 to 31 g at dinner contributing together over 80% of daily protein intake. The majority of dietary protein consumed originated from animal sources (≥60%) with meat and dairy as dominant sources. Thus, 40% of the protein intake in community-dwelling, 37% in frail and 29% in institutionalized elderly originated from plant based protein sources with bread as the principle source. Plant based proteins contributed for >50% of protein intake at breakfast and between 34% and 37% at lunch, with bread as the main source. During dinner, >70% of the protein intake originated from animal protein, with meat as the dominant source.CONCLUSION: Daily protein intake in these older populations is mainly (>80%) provided by the three main meals, with most protein consumed during dinner. More than 60% of daily protein intake consumed is of animal origin, with plant based protein sources representing nearly 40% of total protein consumed. During dinner, >70% of the protein intake originated from animal protein, while during breakfast and lunch a large proportion of protein is derived from plant based protein sources.

The protein transition from animal towards plant proteins, is driven by the growth of the world’s population combined with a rising standard of living. Over the last five years, this has already resulted in a 7-fold increase in product launches with a plant-based claim or notification. This manuscript gives an overview of current, emerging and future protein sources and their use to replace protein in dairy and meat products as well as egg proteins. Currently, a major focus is on the development of products that mimic the original product the most, for example the best meat alternative. However, the question arises if this is enough to change the overall balance between animal and plant proteins? The outlook discusses the demand for a better understanding of consumer needs and preferences.

Developing a reliable method to compare food sustainability is gaining traction, with efforts like those by the Food and Agriculture Organization (FAO). This research aims to contribute to a comprehensive scientific comparison of food categories based on CO2 emissions linked not to weight but to their primary function: nutrient availability and uptake in the consumer’s body. The study utilizes a multi-criteria evaluation for sustainability, incorporating the Nutrient Rich Food (NRF) score, protein digestibility, and essential amino acid content. A case study compares one serving of semi-skimmed milk (SSM) with various plant-based beverages (oat, soy, rice, coconut, and almond), considering their carbon footprints in relation to nutrient content and environmental costs. The analysis integrates protein quality through essential amino acid proportion and digestibility. Findings reveal that achieving an NRF11.3 score of 50 requires more servings of unfortified plant-based beverages than semi-skimmed milk, resulting in higher carbon footprints, except for soy drink. However, when considering emerging farm management measures, semi-skimmed and soy drinks show comparable carbon footprints for a given NRF score. Fortified plant-based beverages (soy, oat, and almond) exhibit lower footprints relative to the calculated NRF scores. Yet, when converting carbon footprints to euros using the European Union Emissions Trading System and adding them to retail prices per kilogram, semi-skimmed milk emerges as the option with the lowest “societal costs” (environment and consumer costs). The research underscores that understanding a food product’s nutritional value requires more than knowledge of its composition; uptake into the body maintenance and potential synergistic effects of other components in the food matrix play crucial roles.

Trends in eiwittransitie kunnen regionaal verschillen. In groeiende economieën verschuiven diëten wereldwijd van plantaardige naar dierlijke eiwitten. In veel economisch ontwikkelde regio's gebeurt echter het tegenovergestelde vanwege de zorg voor milieu en gezondheid. Wij onderzochten de relatie tussen vijf drijvende krachten en eiwittransitietrends zoals deze worden ervaren door jongvolwassenen in ontwikkelde regio's in China (Shanghai) en Nederland (Amsterdam, lees: de Randstad). De onderzochte drijvende krachten waren: milieubewustzijn; het beleid; cultuur; geld; en gezondheid. De gegevens zijn verkregen door 200 vragenlijsten te laten beantwoorden in beide regio's. De resultaten geven aan dat jongvolwassenen in Shanghai meer dierlijke eiwitten consumeren dan plantaardige eiwitten, maar dat er een verandering naar plantaardige eiwitten is ingezet, terwijl de trend van jongvolwassenen in Amsterdam om plantaardig eiwit te consumeren al verder ontwikkeld is. De rangschikking van de drijvende krachten in Shanghai was Geld＞ Milieubewustzijn＞ Gezondheid＞ Cultuur＞ Beleid, en in Amsterdam Gezondheid＞ Milieubewustzijn＞ Geld＞ Beleid＞ Cultuur. Eiwitkeuzes in de voeding van jongvolwassenen worden dus in Shanghai door andere drijvende krachten bepaald dan in Amsterdam

From PLoS website: In general, dietary antigens are tolerated by the gut associated immune system. Impairment of this so-called oral tolerance is a serious health risk. We have previously shown that activation of the ligand-dependent transcription factor aryl hydrocarbon receptor (AhR) by the environmental pollutant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) affects both oral tolerance and food allergy. In this study, we determine whether a common plant-derived, dietary AhR-ligand modulates oral tolerance as well. We therefore fed mice with indole-3-carbinole (I3C), an AhR ligand that is abundant in cruciferous plants. We show that several I3C metabolites were detectable in the serum after feeding, including the high-affinity ligand 3,3´-diindolylmethane (DIM). I3C feeding robustly induced the AhR-target gene CYP4501A1 in the intestine; I3C feeding also induced the aldh1 gene, whose product catalyzes the formation of retinoic acid (RA), an inducer of regulatory T cells. We then measured parameters indicating oral tolerance and severity of peanut-induced food allergy. In contrast to the tolerance-breaking effect of TCDD, feeding mice with chow containing 2 g/kg I3C lowered the serum anti-ovalbumin IgG1 response in an experimental oral tolerance protocol. Moreover, I3C feeding attenuated symptoms of peanut allergy. In conclusion, the dietary compound I3C can positively influence a vital immune function of the gut.

Due to a growing challenge to feed the world’s population and an increased awareness to minimize the impact of our food choices on climate change, a more plant-based diet has gained popularity with a growing number of plant-based products on the market. To stimulate a plant-based diet that also improves long-term health, data are needed to monitor whether these products are healthy alternatives to animal-based foods. Therefore, this study inventoried 916 plant-based meat, fish, and dairy alternatives from eight Dutch supermarkets. The nutritional quality of each product was assessed by (1) the Dutch food-based dietary guidelines and (2) the Nutri-Score. The results show that over 70% of meat, fish, and dairy alternatives have an A/B Nutri-Score (indicating high nutritional quality), but do not comply with the Dutch dietary guidelines. This is mainly due to high salt and low vitamin B12 and iron content (meat and fish alternatives) or low protein and calcium levels (dairy alternatives). In conclusion, the majority of plant-based products are nutritionally not full alternatives of the animal-based equivalents; however, there are still opportunities for reformulation. To aid the consumer in making healthy plant-based food choices, a better alignment between the Nutri-Score and the recommended dietary guidelines is needed.
