E o que diabo é isso?



Ensaios clínicos são testes feitos em pessoas.

A ciência, o método científico vêm se aprimorando cada vez mais, com equipamentos mais sofisticados e uma busca de interpretação de dados mais coerente em busca da verdade.



Alguns de vocês devem se perguntar de onde estou tirando essas informações, o que é FUNDAMENTAL, uma vez que qualquer idiota pode escrever livros, e acreditem, eles os fazem.



Recomendo a leitura de artigos científicos relacionados ao tema. Para quem não sabe interpretá-los ou não gosta, recomendo SEMPRE que comprar um livro, que ele tenha uma quantidade generosa de referências bibliográficas.



Há vasto material que coloquei para os que querem se aprofundar mais no tema: AQUI.



Coloco também abaixo uma tabela de 17 ensaios publicados em revistas internacionais importantíssimas que dietas com restrição racional de carboidratos, são mais apropriadas à saúde.
