A essencial Vitamina D

Ela é fundamental tanto para a mulher grávida quanto para um atleta campeão olímpico. Sua escassez provoca imensos problemas de saúde, mas tê-la em excesso também. Serve ao bebê recém-nascido e ao idoso. É fundamental para o obeso e para o magro. Poucas substâncias servem tão completamente ao organismo quanto a vitamina D.  Até dez anos atrás, a vitamina D estava associada, sobretudo, à manutenção de um esqueleto forte. As descobertas mais recentes da medicina, no entanto, indicam que praticamente todos os tecidos e órgãos se beneficiam dela. “Direta ou indiretamente, a D está relacionada a pelo menos 2.000 genes, o que comprova a sua vasta gama de benefícios”, disse a VEJA o endocrinologista americano Michael Holick, professor da Universidade de Boston, o grande pesquisador do assunto. A vitamina D faz nosso coração bater no ritmo adequado e nossas artérias e veias pulsarem em compasso. É ela que nos garante força muscular e nos protege contra infecções, infartos e derrames, diabetes e alguns tipos de câncer. A falta dela desregula o sistema de fome e saciedade e nos faz engordar.
