Antioxidantes: o que são e o que podem fazer por você!

Vemos esse nome em potes de creme para o rosto e em pacotes de comidas, e até em bebidas… mas exatamente o que são antioxidantes?

Antioxidantes são nutrientes que restauram e retardam a ação do envelhecimento de células no nosso corpo, tudo isso de uma forma natural! Há sugestões de que antioxidantes ajudam a prevenir doenças crônicas e problemas do coração.

Como eles agem no nosso corpo?

Elementos como o sol, poluição e até stress são exemplos de radicais livres que oxidam e deterioram  a membrana celular causando danos em nossa saúde. Quando ingerimos alimentos ricos em vitamina C (um exemplo de antioxidante) ajudamos o corpo a proteger e restituir  os danos causados pela oxidação. Por isso é muito importante incluir esse alimentos em nossa dieta. Exemplos de alimentos que agem como antioxidantes são: cacau, laranjas, tomate, chá verde, cenoura.

Antioxidantes em suplementos alimentares

Os antioxidantes estão disponíveis como suplementos alimentares, mas pesquisas não indicam muito benefício da sua utilização. Embora a investigação apoie aumentar a ingestão de antioxidantes através de fontes alimentares, os resultados não são tão impressionantes quando eles são consumidos individualmente em suplementos.

Extratos antioxidantes muitas vezes mostram resultados impressionantes em estudos de laboratório (tubos de ensaio ou por vezes em animais de laboratório) , mas quando eles são usados ​​em estudos clínicos humanos, os resultados têm sido decepcionantes. Uma exceção foi um estudo do Instituto Nacional do Olho nos E.U.A, que estuda doenças oculares relacionadas à idade, e sugere que uma combinação de antioxidantes reduz o risco de desenvolver estágios avançados de degeneração macular relacionada à idade.Alguns suplementos antioxidantes podem ser prejudiciais para a sua saúde quando tomado em doses elevadas e pode interagir com certos medicamentos. Grandes quantidades de suplementos de vitamina A pode causar defeitos de nascimento quando tomado por mulheres grávidas, e pode aumentar o risco de doenças cardiovasculares e câncer.

A ingestão de grandes doses de vitamina E (mais de 400 unidades internacionais por dia) tem sido associado com um possível aumento na mortalidade total. Isto não se aplica a um suplemento multivitamínico típico. As quantidades de vitaminas A e E incluídas no multivitamínico são pequenos em comparação com esta quantia exagerada.Se você está pensando em consumir grandes quantidades de quaisquer suplementos antioxidantes, você consultar um médico em primeiro lugar .
