A doença cardiovascular é a principal causa da morte nos
países ocidentais, e aproximadamente quase a metade dos indivíduos que contêm
esta doença apresentam níveis de LDL-colesterol elevados no sangue, que podem
ser facilmente modificados com intervenção nutricional.





A redução no consumo de gorduras saturadas é o começo para o
tratamento de LDL-colesterol elevado, mas é necessário mudanças efetivas no
estilo de vida do indivíduo, isso inclui a prática de atividades físicas,
manter o peso ideal e ter bons hábitos alimentares.





Com o avanço tecnológico, o processamento dos alimentos foram
mais intensos, a ponto de extrair componentes alimentares considerados mais
nutritivos e desprezando os considerados pobres, como as fibras. Porém, hoje em
dia sabe-se que a fibra alimentar interfere no funcionamento do aparelho
digestivo, no metabolismo da glicose e lipídios e contribuindo no equilíbrio
das boas bactérias intestinais.





A fibra alimentar é a parte comestível das plantas ou carboidratos que
são resistentes à digestão e à absorção no intestino delgado de humanos, com fermentação
completa ou parcial no intestino grosso. Elas são encontradas, principalmente, nos vegetais, frutas e grãos
integrais.





Na correria diária, estamos deixando de lado os alimentos
naturais e os substituindo por alimentos processados, pobres em fibras. Se no
passado os lanches podiam conter mais frutas, estas foram substituídas por
salgadinhos e doces, alimentos não só ricos em calorias, mas pobres em fibras e
demais nutrientes.





Para quem tem alterações do colesterol, recomenda-se como
parte do tratamento, mudança no estilo de vida, o consumo de 20 a 30g por dia
de fibras (que você pode adquirir consumindo frutas, verduras cruas e cereais
integrais, como aveia, chia, linhaça, ou suplementos, se necessário), prática
de atividade física, e em casos onde a alteração do perfil lipídico for
genética, o uso de medicamentos.





Para um melhor acompanhamento e determinação de uma
alimentação adequada a quem tem colesterol elevado, procure um nutricionista e ele
fará sua reeducação alimentar de acordo com suas necessidades e tratamento.





Não deixe para depois os cuidados com a sua saúde. E
lembre-se que a prevenção começa pela boa alimentação!





Saúde!
