Um punhado de frutos secos por dia pode reduzir o risco de doença cardíaca

Investigadores da Noruega descobriram que comer mais frutos secos e sementes pode ajudar a reduzir o risco de doenças cardiovasculares. Os resultados foram recentemente publicados na revista científica Food & Nutrition Research.

A equipa de cientistas da Universidade de Oslo analisou 60 estudos e estimou que, com cerca de 30 gramas de frutos secos por dia, o risco de sofrer um ataque cardíaco diminui entre 20% e 25%.

Quanto mais frutos secos, melhor

Os adultos nos países nórdicos consomem apenas cerca de 4 gramas de frutos secos por dia ou não os comem de todo, quando deveriam ingerir um punhado diariamente.

O coautor do estudo e investigador da Universidade de Oslo, Erik Arnesen, afirma: "Quanto mais, melhor." E podem ser quaisquer frutos secos — todos eles são muito saudáveis. Os investigadores indicaram que não existe evidência conclusiva que justifique a recomendação de tipos específicos em detrimento de outros. As amêndoas, os pistácios e as nozes são conhecidos por serem os melhores para ajudar a reduzir os níveis de colesterol, enquanto os amendoins são ricos em proteína.

Arnesen declarou no comunicado de imprensa: "Os frutos secos têm um efeito benéfico nos níveis de colesterol no sangue, que é importante manter baixos para prevenir a acumulação de gordura nas artérias. Esta aterosclerose, como é designada, é um dos maiores fatores de risco para os ataques cardíacos."

Os investigadores analisaram estudos que envolveram cerca de 2 milhões de participantes. Investigaram também se o consumo de frutos secos reduzia o risco de acidentes vasculares cerebrais e diabetes tipo 2, mas os resultados não foram tão claros. Não foi possível determinar se os frutos secos afetam a pressão arterial e os níveis de açúcar no sangue.

No entanto, o consumo de frutos secos está associado a uma melhoria dos níveis de colesterol, embora a revisão não permita provar as causas e efeitos exatos. Poderá estar relacionado com a composição dos ácidos gordos presentes nos frutos secos, que é tão benéfica para o coração.

"Graças a esta revisão sistemática e meta-análise, podemos apresentar uma estimativa mais precisa dos efeitos reais. Comprovar que os frutos secos reduzem os níveis de colesterol constitui uma explicação credível para a ligação entre o seu consumo e o risco de doença cardiovascular," afirmou Arnesen.

"Embora os frutos secos não possam ser utilizados para tratar o colesterol elevado, acreditamos que o efeito é suficientemente significativo para ser utilizado como medida preventiva na população em geral," acrescentou.
