“…In general, the Japanese have median calcium intakes below the estimated average requirement in Japan (males aged 18-29 y: 415 mg/d (22) vs. 650 mg/d (23)). Calcium is the body's most abundant mineral and is a major constituent of bones and teeth; insuffi cient intake increases bone resorption (24). The Japanese also have median dietary fi ber intake below the dietary goal for preventing lifestyle-related disease in Japan (males aged 18-29 y: 12.3 g/d (22) vs. Ն19 g/d (25)).…”

Summary "Shushoku," "Shusai," and "Hukusai" are staple food, main dish, and side dish, respectively. The recommended meal in Japan is a combination of "Shushoku," "Shusai," and "Hukusai"; however, it remains unclear whether there is an association between the frequency of these meals and intake of nutrients and food groups. This cross-sectional study examined the association between the frequency of meals combining "Shushoku, Shusai, and Hukusai" and intake of nutrients and food groups among 664 Japanese young adults aged 18-24 y. The dietary habits of the subjects during the preceding month were assessed using a validated brief-type self-administered diet history questionnaire. The frequency of meals combining "Shushoku, Shusai, and Hukusai" was self-reported according to four categories: "less than 1 d or 1 d/wk," "2 or 3 d/wk," "4 or 5 d/wk," and "every day." In both women and men, there was an association between the higher frequency of these meals and higher intake of the following food groups: pulses, green and yellow vegetables, other vegetables, mushrooms, seaweeds, fi sh and shellfi sh, and eggs. Moreover, there was an association with higher intake of protein, polyunsaturated fat, n-6 and n-3 polyunsaturated fat, total dietary fi ber, soluble and insoluble dietary fi ber, ␤-carotene, ␣-tocopherol, vitamin K, thiamin, ribofl avin, folate, pantothenic acid, vitamin C, potassium, calcium, magnesium, iron, and copper, and lower intake of carbohydrate in both women and men. Our fi ndings support the hypothesis that the meals combining "Shushoku, Shusai, and Hukusai" may be associated with intake of many food groups and nutrients among Japanese young adults.

“…However, the low intake of calcium in the study subjects could increase the risk of osteoporosis (Peacock, 1998) because low calcium intake coupled with long periods of elevated calcium requirement may adversely affect bone mineral mass. In addition, a high prevalence of hypovitaminosis D was shown in these subjects of two groups in our earlier study (Islam et al, 2002).…”

Dietary calcium intake in premenopausal Bangladeshi women: do socio-economic or physiological factors play a role?

et al. 2003

Objective: Evaluation of data on dietary calcium intake in premenopausal women of two socio-economic groups in Bangladesh. Design: A cross sectional study. Three days dietary records were used to estimate habitual calcium intake. Setting: Two regions of Bangladesh. The Dhaka city area and the Betagair Union in the sub-district Nandail, Mymensingh. Subjects: A total of 191 subjects of two groups (low socio-economic group ¼ group L, n ¼ 101 and high socio-economic group ¼ group H, n ¼ 90) of Bangladeshi women aged 16 -40 y. About 87% of the subjects were housewives and the rest 13% were distributed in other different professions. Each group consisted of three sub-groups (non-pregnant non-lactating ¼ 1, pregnant ¼ 2 and lactating ¼ 3). Results: The influence of socio-economic status on dietary intake of calcium (P < 0.001) was observed in this study. The dietary intake of calcium was influenced by physiological status (PS) in high income group only (P < 0.005). The mean dietary calcium intake was significantly higher (P < 0.005) in all sub-groups of this group compared with the corresponding sub-groups in low income group. Although in group H, 47% of subjects failed to meet even the lowest level (400 -500 mg=day) of WHO recommended dietary allowances (RDA) of calcium for adult women. No subject in group L was found to meet the RDA level. Moreover, 63% of the women in group L had calcium intake lower than 200 mg=day. These figure could be more critical in both groups if we consider the recent USA-RDAs of calcium for adult women (1000 mg=day). The observed sources of dietary calcium were different in the two groups. Conclusions: The results of the study suggested that low calcium intake could reduce the bone accretion rates and increase the risk of osteoporosis in the subjects of the present study. Calcium rich food may be recommended for women in both groups.

“…One cause of osteoporosis is a nutritional deficiency disorder, a pattern not unlike scurvy, which is a long-term process contributed to by years of a subclinical, marginal lack of vitamin D (Heaney, 1999;Peacock, 1998).…”

Wintertime vitamin D insufficiency is common in young Canadian women, and their vitamin D intake does not prevent it

et al. 2001

Objective: We asked whether women self-reporting the recommended consumption of vitamin D from milk and multivitamins would be less likely to have low wintertime 25-hydroxyvitamin D (25(OH)D) levels. Methods: This cross-sectional study enlisted at least 42 young women each month (age 18 -35 y, 796 women total) through one year. We measured serum 25(OH)D and administered a lifestyle and diet questionnaire. Results: Over the whole year, prevalence of low 25(OH)D ( < 40 nmol=l) was higher in non-white, non-black subjects (25.6% of 82 women) than in the white women (14.8% of 702 white women, P < 0.
