This study analyzed and evaluated the nutritional intake and nutrition quotient for adults (NQ-A) among 21 disabled national athletes preparing for the Tokyo Paralympic competition. A 24-h recall nutrition survey was conducted on the second day of training and one day of the weekend (holidays) to analyze daily nutritional intake. Dietary information was analyzed using the NQ-A questionnaire, which comprises 21 items. The athletes were divided into three groups based on the NQ-A score (High, Middle, Low). A comparative analysis of dietary intake of disabled athletes with the recommended dietary intake amount (RDA) was performed. The intake of carbohydrates (166.9%), proteins (112.3%), vitamin E (112.0%), thiamine (124.6%), riboflavin (100.2%), vitamin B6 (110.6%), vitamin B12 (120.7%), sodium (216.6%), phosphorus (118.3%), iron (146.5%), iodine (143.2%), and selenium (114.2%) was higher than the Korean-recommended amount. In particular, as the results of comparing dietary intake between the three groups showed, the low NQ-A score group had significantly lower intake compared to the %RDA for vitamin E (67.1%), C (26.3%), and Potassium (42.8%). However, with most nutrients, nutritional intake deficiency was not shown to be a problem.

Abstract Background B vitamins and methionine are essential substrates in the one-carbon metabolism pathway involved in DNA synthesis and methylation. They may have essential roles in cancer development. We aimed to evaluate the associations of dietary intakes of vitamin B12, vitamin B6, folate, and methionine with the risk of esophageal cancer (EC) using data from the Japan Public Health Center-based Prospective Study. Methods We included 87,053 Japanese individuals who completed a food frequency questionnaire and were followed up from 1995–1998 to 2013 and 2015. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated by Cox proportional-hazard regression across quintiles of dietary intakes of B vitamins and methionine. Results After 1,456,678 person-years of follow-up, 427 EC cases were documented. The multivariable HR (95% CI) of incident EC in the highest versus lowest quintile of dietary intake of vitamin B12 was 1.75 (1.13–2.71; p-trend=0.01). Stratification analysis based on alcohol consumption showed that higher dietary intakes of vitamin B12 and methionine were associated with an increased risk of EC among never-drinkers; HRs (95% CIs) were 2.82 (1.18–6.74; p-trend=0.009; p-interaction=0.18) and 3.45 (1.32–9.06; p-trend=0.003; p-interaction 0.02) for vitamin B12 and methionine, respectively. Meanwhile, there was no association between vitamin B12 and methionine intake with the risk of EC among drinkers. There were no associations between dietary intake of folate or vitamin B6 and the risk of EC. Conclusion Dietary intake of vitamin B12 was positively associated with the risk of EC in the Japanese population.

The Subject

An excellent report on a form of Vitamin B12 dependency appears in this issue of the Journal. This Commentary, which has been written in response to the article, is the third on the subject of vitamin dependencies, the two previous discussing the Vitamin B6 dependencies (Pediatrics, 37:553, 1966) and Vitamin D dependency (Pediatrics, 45:361, 1970). The term "vitamin dependency" has been used to describe certain types of genedependent nutritional disorders. In such conditions the nutritional intake of vitamin which is required to maintain a state of health is much greater than normal; patients evidently inherit these peculiar requirements in Mendelian fashion.

Methionine Cycle

Growing evidence confirms choline as a critical perinatal nutrient. However, intake levels of choline and betaine among the Spanish fertile population remain unknown. Given their role in one-carbon metabolism with potential epigenetic effects, the aim of the present study was to evaluate the dietary intakes, their adequacy to existing guidelines and the main food sources together with other micronutrients involved in the methylation-methionine cycle (vitamin B6, folates and vitamin B12) in women of childbearing age. The ANIBES study, a cross-sectional study of a representative sample of women of childbearing age (18–45 years, n = 641) resident in Spain, was used. The sample was divided into younger women (18–30 years, n = 251) and older women (31–45 years, n = 390). Dietary intake was assessed by a three-day dietary record by using a tablet device. Total median intakes for the total sample were 303.9 mg/d for choline; 122.6 mg/d for betaine; 1.3 mg/d for vitamin B6; 140.8 μg/d for folates, and 3.8 μg/d for vitamin B12. The older subgroup showed significantly higher choline (p < 0.05), betaine (p < 0.001) and folates (p < 0.05) intakes than younger women. Main food sources for the whole sample were meat and meat products for choline (28.3%), vitamin B6 (25.7%) and vitamin B12 (22.8%); cereals and derivatives (79.9%) for betaine; vegetables (20.0%) for folates. Overall intake adequacy was only observed for vitamin B12, with a very limited number of participants showing adequate intakes for all the other micronutrients. These results illustrate there is a relevant need to raise awareness about optimizing the status of the methionine cycle-related vitamins and cofactors in this potentially vulnerable population.

Diagnostik Und Therapie

ZusammenfassungDie Homocystinurie ist eine seltene angeborene Erkrankung des Methioninstoffwechsels, die mit einer pathologischen Erhöhung der nicht proteinogenen Aminosäure Homocystein und der Ausscheidung ihres Disulfids Homocystin über den Urin einhergeht. Mehrere biochemische und genetische Defekte können zu einer deutlichen Homocysteinerhö-hung führen, darunter Störungen des Vita-min-B6-, Folsäure- und Vitamin-B12-Stoffwechsels, sodass der Terminus Homocystinurie eine Erkrankungsgruppe zusammenfasst. Die häufigste Ursache der Homocystinurie, auch klassische Homocystinurie oder Homo-cystinurie Typ I genannt, stellt die hereditäre Cystathionin-β-Synthase-Defizienz dar, die mit einer Erhöhung von Homocystein und Methionin im Blut einhergeht. Die Diagnose wird durch Bestimmung von Homocystein im Plasma gestellt und kann biochemisch und genetisch gesichert werden. Unbehandelt zeigen sich eine erhebliche Morbidität und Mortalität, die durch Ausschöpfung der therapeutischen Optionen, bestehend aus Vitamin B6, Folsäure, Vitamin B12, Betain und einer Proteinrestriktion mit Aminosäuresupplementie-rung, erheblich reduziert werden können.
