“…It has been proposed (Trinidad et al, 1993) that Ca could pass through the cell membrane more readily in the form of a complex with lower charge. However, a high rate of Ca absorption in the large intestine could trigger a feedback mechanism involving inhibition of duodenal absorption since there is a control of the digestive balance of Ca by endocrine factors (Allen, 1982).…”

Effect of soluble or partly soluble dietary fibres supplementation on absorption and balance of calcium, magnesium, iron and zinc in healthy young men

et al. 1997

Objectives: This study is aimed at investigating the effect of feeding a soluble or partly soluble ®bre rich-diet on the apparent absorption and balance of calcium, magnesium, iron and zinc in healthy young men, by using a chemical balance technique. Study design: Nine healthy young men were given a control diet or the same diet complemented with either inulin (soluble) or sugar beet ®bre (partly soluble) during 28 d periods according to a 3 6 3 latin square design with three repetitions. During the 20 d adaptation period to ®bre ingestion, experimental ®bres were incorporated into bread (60%) and liquid foods (40%)

“…Although the role of the acidic environment in ginger vinegar soup in enhancing non-haem iron absorption was suggested, iron absorption studies would be helpful to con®rm this. It would be valuable if the calcium absorption ef®ciency of the ginger vinegar soup could be measured, as increased calcium absorption has been found in an acid medium (Allen, 1982).…”

Special postpartum dietary practices of Hong Kong Chinese women

et al. 2000

Objective: A`ginger vinegar soup' and other special dietary practices have been traditionally recommended for postpartum Chinese women. This paper describes these practices in the ®rst 6 weeks postpartum, and details of the calcium and iron content of the`ginger vinegar soup'. Design and subjects: Results of this paper were generated from a longitudinal study on the nutritional status of Hong Kong Chinese postpartum women.`Ginger vinegar soup' samples were collected at the 2 week home visits. Calcium and iron content were measured by the combination of dry ashing method and atomic absorption spectrophotometry. Results were compared with other types of soup and food sources. A food frequency questionnaire was completed at the 6 week interview to assess the special dietary practices during this period. Results: Fifty-one subjects completed the food frequency questionnaires. Twenty-two ginger vinegar soup samples and six other soup samples were collected. Consumption of special food items such as ginger, pig's trotters, egg and chicken varied greatly among subjects. More poultry and similar amounts of egg were consumed by our subjects as compared with the Hong Kong general population. Chicken soup and ginger vinegar soup were commonly consumed. Median calcium and iron contents of the ginger vinegar soup were 4.65 and 0.84 mgadl, respectively. This calcium content was higher than that of the other six soup samples, but was low as compared with other calcium-rich foods. Iron content of ginger vinegar soup was higher than that of the other six samples and was comparable to some iron-rich foods. Conclusions: Hong Kong Chinese postpartum women followed traditional dietary practices to different degrees. These practices were characterized by an increased poultry consumption. Iron content of ginger vinegar soup was comparable to some iron-rich foods.

“…A eficiência da absorção de Ca é afetada pela presença intraluminal de outros componentes dietéticos (24). Cerca de 30% do Ca dietético está biodisponível nos alimentos.…”

“…Estudo realizado em pacientes submetidos à dieta para perda de peso, com elevados teores diários de Ca (em torno de 1302 mg/dia) e de fibras, mostrou uma redução no balanço corpóreo de Ca, que passaria de +32 para -77 mg/dia (24). Além disso, em pacientes submetidos a uma dieta geral, o simples acréscimo de frutas e vegetais, apesar de causar um aumento da ingestão de Ca de 1070 para 1166 mg/dia, também provocaria uma queda no balanço do elemento, que passaria de +72 para -122 mg/dia (24).…”

RESUMOO cálcio (Ca) dietético é fundamental para a saúde óssea. Tanto o teor como a biodisponibilidade do elemento nos alimentos devem ser considerados. Este artigo objetiva sumarizar os fatores envolvidos na absorção e destacar os alimentos com melhor disponibilidade do Ca. Este é absorvido principalmente no jejuno e o pH baixo parece favorecer sua absorção, que é maior no crescimento, na gestação/lactação e na carência de Ca ou fósforo (P), e menor no envelhecimento. As maiores fontes, e com melhor absorção, são os laticínios bovinos. Outros alimentos apresentam concentrações elevadas de Ca, mas com biodisponibilidade variável: os ricos em ácidos oxálico e fítico apresentariam uma menor absorção, enquanto que os ricos em carboidratos teriam uma absorção maior. Por apresentarem uma biodisponibilidade do Ca mais próxima da do leite bovino, o leite de outros animais, o de soja enriquecido e alguns vegetais, em quantidades adequadas, poderiam ser usados como alternativas a este. Dietary calcium (Ca) is fundamental to the bone's health. Both the purport and the element bioavailability in the food need to be considered. The purpose of this work was to summarize the factors involved in Ca absorption and point out the sources with higher bioavailability. Ca is mostly absorbed in the jejunum and low pH seems to favor its absorption, which is higher during growth, gestation/lactation and Ca and phosphorus (P) deficiency, and lower with aging. The richest and bestabsorbed Ca source is cow's milk and its derivatives. Other foods show high Ca concentrations but variable bioavailability: foods rich in phytates and oxalates show a smaller absorption and carbohydrate-rich foods show higher absorption. Since Ca bioavailability in other animal's milk, soymilk and some vegetables is closer to that in cow's milk, adequate amounts of these foods could be used as an alternative. O CRESCIMENTO E A MANUTENÇÃO do tecido ósseo dependem de uma grande variedade de fatores genéticos e ambientais. A hereditariedade contribui com cerca de 60 a 70% da expressão fenotípica da densidade mineral óssea (DMO), um dos mais importantes marcadores da saúde do osso.
