Several reports indicate an important role for vitamin K in bone health as well as blood coagulation. However, the current Adequate Intakes (AI) might not be sufficient for the maintenance of bone health. To obtain a closer estimate of dietary intake of phylloquinone (PK) and menaquinones (MKs), PK, MK-4 and MK-7 contents in food samples (58 food items) were determined by an improved high-performance liquid chromatography method. Next, we assessed dietary vitamin K intake in young women living in eastern Japan using vitamin K contents measured here and the Standard Tables of Food Composition in Japan. PK was widely distributed in green vegetables and algae, and high amounts were found in spinach and broccoli (raw, 498 and 307 μg/100 g wet weight, respectively). Although MK-4 was widely distributed in animal products, overall MK-4 content was lower than PK. MK-7 was observed characteristically in fermented soybean products such as natto (939 μg/100 g). The mean total vitamin K intake of all subjects (using data from this study and Japanese food composition tables) was about 230 μg/d and 94% of participants met the AI of vitamin K for women aged 18-29 y in Japan, 60 μg/d. The contributions of PK, MK-4 and MK-7 to total vitamin K intake were 67.7, 7.3 and 24.9%, respectively. PK from vegetables and algae and MK-7 from pulses (including fermented soybean foods) were the major contributors to the total vitamin K intake of young women living in eastern Japan.

Objectives: In Indonesia, many schools do not have school feeding programs, and children usually buy snacks from school canteens or vendors. The history of the country's school feeding programs is not well documented. This study examined Indonesia's nutritional problems and previous school feeding programs. It also investigated the implementation and related challenges in a current pilot national school feeding program known as PROGAS.Methods: We conducted situational analysis by reviewing secondary data and the existing literature. We also measured the impact of PROGAS on students' nutritional status.Results: The review revealed that Indonesia has considerable experience in establishing school feeding programs starting from 1991. The government has established a system from the school to central government level for the quality control, monitoring, and assessment of the pilot program. That program is characterized by its wide scope including improvement in students' dietary intake, promotion of local food, improvement in local agriculture, and community empowerment. However, due to the limited resources allocated to human development, diversity in the country, and difficulty in governance, the low coverage of the program (0.05% in 2013 and 0.14% in 2016) is still a major challenge. Among the students who joined PROGAS project, nutritional intake significantly increased during the project, while there were no changes in the control group.Conclusions: Low coverage of the school feeding program is still a major challenge in Indonesia. In the future, government regulations to increase the program's coverage and nutrition education on all forms of malnutrition targeting school-aged children is necessary.

The purpose of this study was to estimate the usual intake distribution of calcium and vitamin B1 of fifth-grade children based on a 3-d dietary survey and to assess nutrient intake using Dietary Reference Intakes (DRIs 2010). A cross-sectional study was undertaken from October 2007 to February 2008 in schools located in Tokyo and Okayama, Japan. A total of 94 fifth-grade children attending 5 elementary schools participated in the study. The weighed plate waste method and observation were used to collect data on the school lunches and dietary records by children, accompanied by photographs used to collect data on meals at home. The study lasted 3 d, 2 non-consecutive days with school lunches and 1 d without. The estimated proportion of subjects below the Estimated Average Requirement (EAR) for calcium intake with milk in the school lunch decreased by 40% compared to the calcium intake without milk in the school lunch. Vitamin B1 intake from less than 0.45 mg/1,000 kcal fortified rice was estimated to be 0%. The intake distribution of calcium has increased by 150 mg by taking milk and the intake distribution of vitamin B1 has increased 0.20 mg by taking fortified rice in the school lunch. Calcium and vitamin B1 intake in the school lunch has changed the distribution of calcium and vitamin B1 intake upward, and decreased the number of estimated subjects that were below EAR. However, the distribution was not shifted across the board and the shape of the distribution has changed.
