Cálcio é o mineral mais abundante no corpo humano. A função primordial do cálcio é a formação de ossos e dentes, bem como sua manutenção. O cálcio é extremamente importante também para diversas outras funções vitais, como contração muscular apropriada, batimentos cardíacos saudáveis e no combate à osteoporose.

Podemos destacar algumas doenças decorrentes da falta de cálcio no organismo:

Osteoporose: Esta doença é originada pela perda de massa óssea, podendo ocorrer fraturas.
Osteomalácia: Muito confundida com a osteoporose, nesta doença ocorre uma falha na mineralização da matriz óssea, causando também fraturas.
Raquitismo: É uma doença que provoca má formação dos ossos, durante o período de crescimento.

Para evitar essas doenças e para que o seu organismo exerça as funções da melhor maneira possível, é importante consumir todos os dias alimentos fontes de cálcio. A recomendação diária para adultos é de 1.000mg.

A absorção de cálcio pode ser prejudicada por alguns fatores, como a presença de ferro, um mineral presente em carnes e ovos. Por isso procure não consumir alimentos ricos em ferro junto com alimentos ricos em cálcio, como por exemplo: carne bovina e leite desnatado. Já outras substâncias podem aumentar a absorção do cálcio pelo organismo, como é o caso da lactose do leite. O leite é uma fonte riquíssima de cálcio, e este cálcio é muito bem absorvido devido à lactose (açúcar do leite), que contribui para sua maior absorção. A vitamina D também aumenta a absorção de cálcio, por isso procure consumir alimentos ricos em vitamina D juntamente com o cálcio. A maior fonte de vitamina D é obtida através da luz solar na pele. Os raios solares colaboram com a produção desta vitamina no organismo humano, que por sua vez, ajuda a fixar o cálcio.

Fontes de vitamina D: óleo de fígado de peixes, peixes como atum, cação, arenque, além de manteiga, gema de ovo, entre outros.
