TL;DR: This study indicates that a vegetarian lifestyle has no negative impact on the health status at older age, and generally shows a similar profile for V and NV concerning dietary intake, blood values, and physical characteristics.
Abstract: Background Epidemiological studies indicate that a well balanced vegetarian diet offers several health benefits including a lower prevalence of prosperity diseases in vegetarians compared to omnivores. It was the purpose of the present study to compare nutritional and physical characteristics in matched samples of institutionalized vegetarian (V) and non-vegetarian (NV) elderly.

TL;DR: Differences in the intake of selected nutrients in foods between low and high fat consumers, unexpectedly, did not result in different plasma concentrations of cholesterol, nor did it result in differences in fat soluble vitamins.
Abstract: Presently, no national dietary guidelines--neither food- nor nutrient-based--exist for Austria. Usually, the recommendations of the German Society of Nutrition are used instead. The determination of national characteristics of nutritional behaviour and food consumption can reveal starting-points for the improvement of nutritional status in Austria. Seven-day weighed records (children and adolescents, n = 2.173) and 24-h-recalls (adults, n = 2.488) were used for the evaluation of nutrient intake and food consumption. For a sub-sample of children and adolescents, results from laboratory assessment of biomarkers were also available (n = 1.400). Based on fat intake, the age groups were divided into low fat intake (less than 25th percentile = 28-34% fat energy) and high-fat eaters (greater than 75th percentile = 38-45% fat energy). Approximately 75% of the Austrian population have fat intakes above 30% of energy intake, older age groups having a higher prevalence of high fat intakes. Intakes of saturated fatty acids reach 40-46% of total fat. The usual intake of dietary fibre in the Austrian population is between 17-21 g/d; some individuals are able to achieve the recommended intakes for dietary fibre, but do not represent a significant majority of the population. The mean intakes of fruits are clearly higher in children and adolescents (10% of total food intake) than in adults (2-6%). Differences in the intake of selected nutrients in foods between low and high fat consumers, unexpectedly, did not result in different plasma concentrations of cholesterol, nor did it result in differences in fat soluble vitamins. Therefore, one of the primary dietary guidelines for Austria should be the reduction of fat consumption, which is also associated with increasing intakes of fruits and vegetables, increasing intakes of dietary fibre and decreasing intakes of cholesterol.

TL;DR: Vitamin K2 meets all criteria for a bioactive substance recommended for an RDI and should be considered for a specific dietary recommendation intake, whereas the dietary form vitamin K1 has a shorter half-life.
Abstract: Vitamin K and its essential role in coagulation (vitamin K [Koagulation]) have been well established and accepted the world over. Many countries have a Recommended Daily Intake (RDI) for vitamin K based on early research, and its necessary role in the activation of vitamin K-dependent coagulation proteins is known. In the past few decades, the role of vitamin K-dependent proteins in processes beyond coagulation has been discovered. Various isoforms of vitamin K have been identified, and vitamin K2 specifically has been highlighted for its long half-life and extrahepatic activity, whereas the dietary form vitamin K1 has a shorter half-life. In this review, we highlight the specific activity of vitamin K2 based upon proposed frameworks necessary for a bioactive substance to be recommended for an RDI. Vitamin K2 meets all these criteria and should be considered for a specific dietary recommendation intake.

TL;DR: No significant correlation was shown between low dietary zinc intakes and low serum zinc levels during either early or late pregnancy, and zinc and protein intakes were highly correlated in both early and late pregnancy.
