LIMA, Giuseppina Pace Pereira; ROCHA, Suraya Abdallah da; TAKAKI, Massanori  and  RAMOS, Paulo Roberto Rodrigues. Polyamines contents in some foods from Brazilian population basic diet. Cienc. Rural [online]. 2006, vol.36, n.4, pp. 1294-1298. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782006000400039.

The level of polyamines changes as well as the daily necessity since they are directly related to the cell growth. In the present work we analyzed the levels of putrescine, spermidine and spermine in several foods from vegetables and eggs. The cooking did not affect the level of polyamines in rice and bean, but in potato there were differences and frying process increased the level of putrescine. Lettuce, orange, banana and tomato presented significant levels of putrescine while onion, garlic, egg, rice and bean presented specially spermidine and spermine. Those results can help for elaboration of dietary guidelines according to the level of polyamines of those foods and their daily necessity.

Keywords : putrescine; spermidine; spermine; vegetables; eggs.
