BACKGROUND
A healthy nutrition in pregnancy supports maternal health and fetal development, decreasing the risk for adverse pregnancy outcomes. Guidance by prenatal care professionals can increase women's awareness regarding the importance of nutrition in pregnancy and thereby contribute to a reduced risk for adverse pregnancy outcomes. The aim of this study was to assess the needs, wishes and preferences of pregnant women regarding the interprofessional guidance on nutrition in pregnancy.
METHODS
Using a qualitative approach and a purposive maximum variation sampling strategy, 25 pregnant women were recruited to participate in six semi-structured, guideline-oriented online focus groups. In addition, two semi-structured, guideline-oriented interviews, with a midwife and an obstetrician, were conducted. The focus groups and interviews were audio-recorded and transcribed. Transcripts were analysed using a systematic deductive-inductive approach to qualitative content analysis according to Kuckartz.
RESULTS
Focus group participants covered diverse perspectives in terms of their age, different models of prenatal care as well as dietary forms from omnivorous to vegan. The majority of women perceived the guidance on nutrition during pregnancy as insufficient. Involved healthcare professionals, namely midwives and obstetricians, should provide more consistent information, especially to avoid uncertainties exacerbated by the internet and social media. There is a need for individual nutrition information regarding dietary supplements and the specifics of different dietary forms during pregnancy, such as a vegan diet. The majority of participants supported the integration of a free-of-charge professional nutrition counselling in prenatal care. Interviews with experts identified time pressure and the complexity of nutrition as a topic as the main obstacles in consultation settings. Both midwife and obstetrician emphasised the need for improved professional education on nutrition in pregnancy in their respective studies.
CONCLUSION
Professional guidance for pregnant women on nutrition and uncertainties going along with certain forms of diet during pregnancy could alleviate the burden and overwhelming amount of web-based information. Additionally, information adapted to the needs, wishes and preferences of pregnant women would improve prenatal care through a more personalised approach. The quality of nutrition guidance in pregnancy should be improved by the implementation of this topic in the education of involved healthcare professionals.

Habitat loss for food production is a key threat to global biodiversity. Despite the importance of dietary choices on our capacity to mitigate the on-going biodiversity crisis, unlike with specific ingredients or products, consumers have limited information on the biodiversity implications of choosing to eat a certain popular dish. Here we estimated the biodiversity footprints of 151 popular local dishes from around the world when globally and locally produced and after calorical content standardization. We find that specific ingredients (beef, legumes, rice) encroaching on biodiversity hotspots with already very high agricultural pressure (e.g. India) lead to high biodiversity footprint in the dishes. Examples of high-biodiversity-footprint popular dishes were beef dishes such as fraldinha (beef cut dish) originating from Brazil and legume dishes such as chana masala (chickpea curry) from India. Regardless of assuming locally or globally produced, feedlot or pasture livestock production, vegan and vegetarian dishes presented lower biodiversity footprints than dishes containing meat. Our results demonstrate the feasibility of analysing biodiversity footprint at the dish level across multiple countries, making sustainable eating decisions more accessible to consumers.

Randomized Controlled Trial
The Nutritious Eating with Soul study was a 24-month, randomized behavioral nutrition intervention among African American adults. This present study, which is a secondary analysis of the NEW Soul study, examined changes in dietary acceptability, restraint, disinhibition, and hunger. Participants (n = 159; 79% female, 74% with ≥ college degree, mean age 48.4 y) were randomized to either a soul food vegan (n = 77) or soul food omnivorous (n = 82) diet and participated in a two-year behavioral nutrition intervention. Questionnaires assessing dietary acceptability (Food Acceptability Questionnaire; FAQ) and dietary restraint, disinhibition, and hunger (Three-Factor Eating Questionnaire; TFEQ) were completed at baseline, 3, 6, 12, and 24 months. Mixed models were specified with main effects (group and time) and interaction effects (group by time) to estimate mean differences in FAQ and TFEQ scores using intent-to-treat analysis. After adjusting for employment, education, food security status, sex, and age, there were no differences in any of the FAQ items, total FAQ score, dietary restraint, disinhibition, and hunger at any timepoint except for one item of the FAQ at 12 months. Participants in the vegan group reported a greater increase in satisfaction after eating a meal than the omnivorous group (mean difference 0.80 ± 0.32, 95% CI 0.18, 1.42; P = 0.01). This is one of the first studies to examine differences in dietary acceptability, hunger, and other eating factors among African American adults randomized to either a vegan or omnivorous soul food diet. The findings highlight that plant-based eating styles are equally acceptable to omnivorous eating patterns and have similar changes in hunger, restraint, and disinhibition. These results suggest that plant-based eating styles can be an acceptable dietary pattern to recommend for cardiovascular disease prevention and may result in greater post-meal satisfaction.

Sustainable healthy diets are promoted, and consequently vegetarian diets are currently increasing. However, scientific information on their effects on bone health is scarce. A cross-sectional study was performed in adults (66% women) classified into three groups: omnivores ( = 93), lacto-ovo vegetarians ( = 96), and vegans ( = 112). Nutrient intake, body composition, physical activity, vitamin D status (25-hydroxycholecalciferol, 25-OHD), parathormone (PTH), and bone formation (bone alkaline phosphatase, BAP) and resorption (N-telopeptides of type I collagen, NTx) markers were determined. Lacto-ovo vegetarians and especially vegans showed lower protein, fat, calcium, phosphorous, vitamin D, retinol, iodine, and zinc intakes, and higher carbohydrate, fibre, carotenes, magnesium, and vitamin K intakes compared to omnivores. Body composition was similar in the three groups that performed vigorous physical activity regularly. Body bone mass and muscle mass were positively correlated with BAP, and time performing physical activity with 25-OHD. The prevalence of vitamin D deficiency or insufficiency (25-OHD < 75 nmol/L) was 93.7% in the studied population, and vitamin D deficiency (25-OHD < 25 nmol/L) was significantly higher in vegans. Vegetarians of both groups had increased PTH and NTx with vegans showing significantly higher PTH and NTx than omnivores. Conclusion: Adult vegetarians, especially vegans, should reduce the risk of bone loss by appropriate diet planning and vitamin D supplementation.

This article explores the factors influencing the choice of general practitioners (GPs) and their role in the health care of vegans in Austria. The number of people identifying as vegan is on the rise, and GPs are increasingly confronted with vegan patients. A qualitative method was chosen for this study, and 14 semi-structured interviews with vegans were conducted between April 2022 and July 2022. Participants were recruited primarily through vegan social media groups. In their experiences with health care, vegans felt treated unequally or sometimes incorrectly. The experiences described highlight that participants felt that most GPs were biased against their veganism. Information exchange among vegans primarily takes place online and through publications of vegan associations, while GPs play a minor role in information provision. As the number of vegans grows, an appreciative way of communicating between GPs and vegan patients ought to be promoted. Voluntary interdisciplinary nutritional training, collaboration of the medical field with support organizations, provision of evidence-based information, and collaboration with dietitians and nutritionists could enrich the care of patients with a vegan diet.

Randomized Controlled Trial
BACKGROUND
The beneficial effects of a plant-based diet on gut microbiota diversity are well documented, however, its impact on clinical bowel health and defecation patterns are less well understood. Vegetarian diets have been associated with a higher bowel movement (BM) frequency as well as softer stools in cross-sectional studies. The effects of the de-novo adoption of a vegan diet on bowel health, however, have never been investigated in a randomized-controlled trial.
MATERIALS AND METHODS
The present study examined bowel health and defecation patterns in relation to diet and nutrient intake in a young and healthy sample of = 65 physically-active German university students who were randomly assigned to either a vegan or a meat-rich diet for eight weeks. Bowel health assessment included the Bristol Stool Form Scale (BSFS), the Gastrointestinal Quality of Life Index (GIQLI) and the Cleveland Clinic Fecal Incontinence Score (CCFIS). Nutrient intake was assessed using weighed food diaries. The study was prospectively registered at the German Clinical Trial Register (DRKS00031541).
RESULTS
Weekly BM frequency slightly increased in vegans, whereas it remained unaltered in participants assigned to a meat-rich diet. Fiber intake increased significantly in vegans (34.89 (18.46) g/d) whereas it decreased in those assigned to the meat-rich group (22.79 (12.5) g/d). No significant intergroup differences in BSFS and CCFIS patterns were observed. Adoption of a vegan diet neither resulted in a transient increase in abdominal discomfort nor in a decreased gastrointestinal quality of life, which was comparable across the diet groups.
CONCLUSIONS
The short-term adoption of a vegan diet did not negatively affect markers of bowel health in this study.

Review
Nutraceuticals represent substances derived from food or plants that provide medical or health benefits, and are increasingly sought by patients as a means of treating migraine in a natural, effective, and safe manner as conventional therapies often fail, are expensive, and laden with side effects. This chapter reviews various nutraceutical therapies for migraine including phytomedicines (plant-based therapies), diets for migraine management and vitamin, mineral, and supplement-based treatments for migraine with respect to preclinical and clinical evidence. Reviewed herein are a multitude of nutraceutical options for the treatment of migraine including vitamins (e.g., riboflavin), antioxidants, and plants/phytomedicines: feverfew, butterbur, cannabis, St. John's Wort, Rosa x damascena, and Gingko biloba. Dietary interventions for migraine include low lipid, vegan, ketogenic, and DASH (dietary approaches to stop hypertension). Supplements such as polyunsaturated fatty acids (PUFAs) as well as l-carnitine, pre/probiotics, and melatonin are also discussed. Migraine patients and their caregivers have an armamentarium of nutraceutical options to treat headache. While some therapies such as vitamins harbor stronger evidence with more rigorous studies, patients may also choose dietary therapies that may offer more systemic health benefits while also improving migraine. As cannabis legalization spreads worldwide, care providers must be aware of the limited evidence in migraine. Future studies may explore traditional ancient medicines for migraine at basic science and clinical level, while currently adopted and new nutraceutical treatments may benefit from partnership with industry to engage in larger trials in humans.

BACKGROUND
Breastfeeding is important for the healthy growth and development of newborns, and the nutrient composition of human milk can be affected by maternal nutrition and supplementation. In Germany, iodine supplementation is recommended for all lactating mothers, and docosahexaenoic acid (DHA) supplementation is recommended for mothers with inadequate or no fish intake. Vitamin B12 supplementation is required for strict vegans during lactation, and other nutrient supplementation may be necessary depending on the individual's nutritional status. To address the lack of data on dietary supplements used by lactating mothers following a vegetarian or vegan diet, an online survey was conducted in Germany, with a focus on iodine, DHA, and vitamin B12.
METHODS
Study participants were asked to report whether they followed specific dietary patterns (omnivorous [OM], vegetarian [VT], vegan [VN]) as well as their use of dietary supplements. Relationships between diets and supplement use were analyzed using chi-square tests.
RESULTS
2054 lactating women were included (1240 OM, 410 VT, and 404 VN) in this analysis. Within OM, VT and VN, at least one dietary supplement was taken by 67.3%, 84.9% and 98.0% respectively (p < 0.001). Overall, 53.2% OM, 66.8% VT, 88.4% VN reported taking at least one supplement containing iodine (p < 0.001). 54.6% OM, 61.7% VT and 58.2% VN reported supplements containing vitamin B12, while 34.1% OM, 40.2% VT and 38.6% VN mentioned supplements containing DHA (p < 0.05).
CONCLUSION
More than half of the participants reported the use of supplements during lactation with the highest proportion in vegans. However, over one third of the mothers did not report supplementing with iodine, regardless of their dietary pattern and most participants also did not report DHA supplements. It is worrisome that a high number of vegans did not report vitamin B12 supplementation, but this could be partly due to issues with reporting. It is crucial to provide further education to breastfeeding mothers about the importance of taking micronutrient supplements, especially for those following a vegetarian or vegan diet. This will help ensure that mothers and their breastfed infants receive optimal nutrition for a healthy development.

Plant-based alternatives (PBAs) are increasingly becoming part of diets. Here, we investigate the environmental, nutritional, and economic implications of replacing animal-source foods (ASFs) with PBAs or whole foods (WFs) in the Swedish diet. Utilising two functional units (mass and energy), we model vegan, vegetarian, and flexitarian scenarios, each based on PBAs or WFs. Our results demonstrate that PBA-rich diets substantially reduce greenhouse gas emissions (30-52%), land use (20-45%), and freshwater use (14-27%), with the vegan diet showing the highest reduction potential. We observe comparable environmental benefits when ASFs are replaced with WFs, underscoring the need to reduce ASF consumption. PBA scenarios meet most Nordic Nutrition Recommendations, except for vitamin B12, vitamin D and selenium, while enhancing iron, magnesium, folate, and fibre supply and decreasing saturated fat. Daily food expenditure slightly increases in the PBA scenarios (3-5%) and decreases in the WF scenarios (4-17%), with PBA diets being 10-20% more expensive than WF diets. Here we show, that replacing ASFs with PBAs can reduce the environmental impact of current Swedish diets while meeting most nutritional recommendations, but slightly increases food expenditure. We recommend prioritising ASF reduction and diversifying WFs and healthier PBAs to accommodate diverse consumer preferences during dietary transitions.
