Dear Sustag friends,
	To add a tip to organic quality in my own research, monitoring  nitrate levels 
in fresh vegetables, I found differences  between organic and conventional, at tropical 
Rio de Janeiro market been up to 4.8 times greater in conventional produce. In 
another words, some one, with a weight of 60Kg, who eats 100g of conventional spinach 
would have load up to 23%  of his daily intake of nitrate, as suggested in UN-.
	Nitrate built up, in general speaking, is not a big trouble around here yet, but 
I just read a papper abstract today - "Modulation of nitrate-nitrite conversion in the 
oral cavity". Van Maanen, Johannes M.; Van Geel, Allan A.; Kleinjans, Jos C.(Department 
of Health Risk Analysis and Toxicology, University of Limburg, Maastricht, Neth.).  
Cancer Detect. Prev., 20(6), 590-596: Journal CA Section: 13 (Mammalian Biochemistry)- 
where the authors were talking about the possibility of modulation of the conversion of 
nitrate into nitrite in the oral cavity in order to seek ways of reducing the formation 
of the deleterious nitrite. I learned  that mouthwash solns., toothpaste and chewing gum 
can be used with confidence to control endogenous nitrosation resulting in the formation 
of carcinogenic N-nitroso compds.
	I start to wonder about Geraldo DEFFUNE email with references and the opnion of 
Guillermo Romero

that, i can not argue, usual statistics, good references/research or what we see 
clear some times is not enough to understand things.
	That organic produces are healthier than conventional vegetables, no doubt. The 
matter is just like not to be a  passive smockers. Eat organic is a step up perception 
in give healthy to our family, community, city, state and of course the planet. 
	If we can choose and if we have the knowledge, why do not choose?
