Plant-based (PB) diets are associated with good health and are also recommended for environmental sustainability. The present review aimed to summarise the definitions of PB diets globally and to investigate the nutritional role of PB diets in adults. This review found that there is a wide range of PB definitions ranging from the traditional vegetarian diets (including vegan) to semi-vegetarian/flexitarian diets. Furthermore, other diets which were originally developed due to their associations with positive health outcomes, such as the portfolio, Mediterranean-style, DASH, healthy US-style, planetary health and Nordic-style diets, have been encompassed in PB definitions due to their emphasis on certain PB components. This review has highlighted that those consuming a PB diet are more likely to meet recommended intakes for carbohydrate, dietary fibre and vitamin E and are less likely to meet recommendations for protein, vitamin B12 and iodine compared to omnivores. Regardless of consumer type, neither PB consumers nor omnivores met recommendations for intakes of vitamin D, calcium and sodium. While intakes of protein, n-3, iron and zinc were generally sufficient from the PB diet, it is important to acknowledge the lower bioavailability of these nutrients from PB foods compared to animal-derived products. As dietary patterns shift towards a more PB diet, there is a need for further studies to investigate the role of PB diets for nutritional adequacy and status in populations currently accustomed to consuming a primarily omnivorous diet.

EU legislation on nutrition and health claims made on foods (Regulation (EC) No. 1924/2006) specifies that health claims should be only authorised for use in the Community after a scientific assessment of the highest possible standard is carried out by the European Food Safety Authority (EFSA). This paper focuses on the scientific substantiation of health claims within the context of the EU Regulation. The evaluation of the substantiation of health claims is carried out by the EFSA Scientific Panel on Dietetic Products, Nutrition and Allergies (NDA). The EFSA has published extensive guidance to assist applicants in the preparation of applications for authorisations of health claims. This guidance summarises the general principles applied by the NDA Panel in the evaluation of health claims, including the scientific criteria for substantiation, as well as the scientific requirements for the substantiation of specific health claims. To date, the EFSA NDA Panel has concluded that a wide range of health claims has been substantiated. These include claims for many well-established functions of nutrients, as well as beneficial effects of foods and food constituents on a range of body functions. In addition, claims have been substantiated on the role of nutrients in growth and development of children and on the effects of nutrients and food constituents on reduction of risk factors for disease. EFSA evaluations and guidance have made an important contribution to the understanding of the scientific substantiation of health claims which will help to set new directions for research and will guide future innovation.

Recent evidence suggests that menaquinones (Vitamin K2) may be important for both bone health and cardiovascular health. With the exception of menaquinone-4 which is formed from the tissue specific conversion of phylloquinone or menadione, menaquinones are synthesized by bacteria. They are typically found in foods of animal origin such as meat, dairy and fermented foods and may account for up to 25% of total vitamin K intake. There are few data available on menaquinone intakes in population groups due to lack of available composition data. The Irish food composition database however has recently been updated to include data on menaquinones. Therefore, the aim of this study was to use these data to estimate the intakes and key dietary sources of menaquinones (menaquinone-4 & menaquinone-5–10) in the Irish population. Analyses included data from four nationally representative surveys of the Irish population; The National Pre-School Nutrition Survey (1–4y; 2010–2011), the National Children's Food Survey (5–12y; 2003–2004), the National Teens' Food Survey (13–17y; 2005–2006) and the National Adult Nutrition Survey (18–90y; 2008–2010) (www.iuna.net). For all of the surveys, food and beverage intake data (including supplements) were collected using food records and quantified using food scales, photographic atlases, household measures and standard portion sizes. Mean daily intakes of menaquinone-4 and menaquinone-5–10 were estimated using UK food composition tables and analytical values from published papers. The percent contribution of food groups to menaquinone intake was calculated by the mean proportion method (which provides information about the sources that are contributing to the nutrient intake 'per person'). Statistical analyses were carried out using SPSS© V22. Mean intakes of menaquinone-4 ranged from 8–12μg/d and 10–14μg/d in children aged 1–17 years and adults aged 18–90 years, respectively. Mean combined intakes of menaquinone-5–10 ranged from 32–43μg/d and 32–50μg/d in children aged 1–17 years and adults aged 18–90 years, respectively. 'Meat & meat products' were the top contributor of menaquinone-4 (50–66%) intakes across all population groups followed by 'milks' (9–25%). 'Meat & meat products' (44–61%) and 'cheeses' (21–37%) were important contributors to menaquinone-5–10 intakes across all population groups examined. This study is the first of its kind to report the intakes and sources of menaquinones in the Irish population. 'Meat & meat products', 'cheeses' and 'milks' are important contributors to intakes of menaquinones in the Irish diet. Further research is required to fully understand the role of the menaquinones in human health. [ABSTRACT FROM AUTHOR]
