The paradox of PAHs


The primary soup and the major role of PAHs

Life needs organic molecules. Those organic molecules were initially synthesized endogenously and delivered exogenously.













The PAHs production in human societies and their risks

Both combustion of fossil and biomass fuels and cooking produce PAHs.
They are carcinogenic for animals and human.
But it seems that they are also linked to epigenetic changes which lead to asthma and allergy. So you can cook but try to produce the least of PAHs... As our ancestors probably did because of the scarce avalilability of energy.
