Vegan diet consumption is gaining popularity globally and in New Zealand. However, plant foods provide absent or limited quantities of important micronutrients such as vitamin B12, iron, zinc, and omega-three fatty acids(1). A restrictive and unplanned vegan diet may thus increase risks of nutrient deficiencies especially during pregnancy and early life if the nutrient demands are not fulfilled. Health professionals who provide primary support for pregnant women and their children are important figures in monitoring the nutritional statuses during the antenatal and postnatal periods(2). (Being knowledgeable about the nutritional risks of poorly-planned vegan diets, and having access to appropriate educational resources would support vegan mothers and children to achieve a well-balanced diet. Currently, there are insufficient studies investigating the perspectives of New Zealand’s health professionals within the realm of vegan diets during pregnancy and early life. The aim of the research is to utilise a mixed-methods approach to explore these concerns, attitudes, and experiences. Healthcare professionals, including dietitians, nurses, general practitioners and midwives were invited to participate in the study. Knowledge and attitude scores were collected with an online questionnaire and scores were recorded as a proportion of the participants. Subsequently, descriptions of experiences, concerns, and perspectives about the adoption of vegan diets during pregnancy and early life were collected with semi-structured interviews. A total of 14 health professionals completed the study. All health professionals showed positive attitudes towards the adoption of vegan diets during pregnancy but some exhibited greater concern about their restrictive nature especially in early childhood. Achieving intake adequacy and subjecting young children to intensive assessments for nutrient adequacy were among the concerns raised. More than 90% of health professionals were concerned about iron and vitamin B12 deficiencies while less than 50% were concerned about deficiencies in protein, omega-three fatty acids, iodine, zinc and vitamin D. Less than 50% of participants were aware that plant foods do not provide sufficient vitamin B12. More than 50% disagreed that sufficient information about vegan diets during pregnancy and early life is available. Insufficient evidence-based consensus and government guidelines, and limited access and referrals to dietitians for guidance on vegan diets were highlighted as challenges that reduce the overall knowledge and confidence. Hence, continual professional education and updated evidence-based resources would be important steps to support health professionals in providing guidance to individuals on vegan diets.

Dietary recommendations suggest decreased consumption of SFA to minimise CVD risk; however, not all foods rich in SFA are equivalent. To evaluate the effects of SFA in a dairy food matrix, as Cheddar cheese, v. SFA from a vegan-alternative test meal on postprandial inflammatory markers, a randomised controlled cross-over trial was conducted in twenty overweight or obese adults with metabolic abnormalities. Individuals consumed two isoenergetic high-fat mixed meals separated by a 1- to 2-week washout period. Serum was collected at baseline, and at 1, 3 and 6 h postprandially and analysed for inflammatory markers (IL-6, IL-8, IL-10, IL-17, IL-18, TNFα, monocyte chemotactic protein-1 (MCP-1)), acute-phase proteins C-reactive protein (CRP) and serum amyloid-A (SAA), cellular adhesion molecules and blood lipids, glucose and insulin. Following both high-fat test meals, postprandial TAG concentrations rose steadily (P < 0·05) without a decrease by 6 h. The incremental AUC (iAUC) for CRP was significantly lower (P < 0·05) in response to the cheese compared with the vegan-alternative test meal. A treatment effect was not observed for any other inflammatory markers; however, for both test meals, multiple markers significantly changed from baseline over the 6 h postprandial period (IL-6, IL-8, IL-18, TNFα, MCP-1, SAA). Saturated fat in the form of a cheese matrix reduced the iAUC for CRP compared with a vegan-alternative test meal during the postprandial 6 h period. The study is registered at clinicaltrials.gov under NCT01803633.
