“…This theory was based on the earlier observation (Thornton and Moreng, 1959), that the presence of this vitamin in the diet maintained a higher feed intake during hot weather. It has also been shown by Leichsenring et al (1957), that ascorbic acid enhanced the uptake of calcium. In view of these data, it would seem that ascorbic acid should increase the intake of calcium into the intestinal tract and its uptake from this organ to the body.…”

“…Realmente, o efeito que os alimentos vegetais exercem sobre a biodisponibilidade do Ca parece depender de inúmeros fatores. O ácido ascórbico, por exemplo, aumenta a absorção do elemento: a adição de 25 mg desta vitamina (que corresponde a 65 mg de suco de laranja) a uma dieta contendo 336 mg de Ca, melhora a absorção do elemento de 50 para 100 mg/dia (30).…”

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.

“…The addition of ascorbic acid to the diet increased calcium absorption in women (19) and in children (20). Ascorbic acid administration decreased calcium excretion in humans whose initial leucocyte ascorbic acid levels were below normal, but did not affect calcium excretion in subjects with normal leucocyte ascorbic acid levels (21).…”

“…Animal experiments have shown that ascorbic acid administration caused a mobilization of calcium from cultured embryonic chick tibias (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29) and an increase in urinary calcium excretion from chicks (30) during the initial time of treatment. After 24 hours this effect was lost and eventually normal levels were attained.…”

“…However, the relatively small amount of ascorbic acid (2g) used in this study is probably not sufficient to affect the change in calcium excretion. The overall increase in calcium excretion is probably due to the increase in intestinal absorption of calcium because of the chelating action of ascorbate with calcium ion since ascorbic acid is capable of increasing calcium absorption in humans (19,20) and in rats (4). The increase in calcium excretion is probably transient because results from the first experiment showed that large doses of ascorbic acid (10g daily) did not affect long-term calcium elimination.…”

SummaryThe long-term and short-term influence of large oral doses of ascorbic acid on the urinary excretion of calcium has been investigated. In the first experiment, daily doses of a total of 10g of ascorbic acid were administered to healthy human subjects. Daily urinary samples of these subjects were collected before and during the treatment, and calcium contents of these samples were measured. Among the 22 subjects, 19 experienced no significant changes in urinary calcium levels during the ingestion of ascorbic acid, one subject experienced an increase, two had a decline. These changes in urinary calcium levels were relatively small and were within the changes from consuming normal diets.
