Both proponents and opponents of Nova 'agree that food processing vitally affects human health', but not on its definition of ultra-processing. [ 18 ] [ 19 ] [ 20 ] Nova is an open classification that refines its definitions gradually through new scientific publications rather than through a central advisory board.
First, the demand for an organic product is larger than the number of organic products available. Without synthetic pesticides, quantities of foods will be smaller. This smaller production of organic food means an increased cost. Also, the amount of labour per unit of food is larger compared to the mass production of non-organic products. [5]
While there may be some differences in the amounts of nutrients and anti-nutrients when organically produced food and conventionally-produced food are compared, the variable nature of food production and handling makes it difficult to generalize results, and there is insufficient evidence to make claims that organic food is safer or healthier ...

S and N in organic carbon source are transformed into H 2 S and NH 4 + through desulfurylation and deamination, respectively. [40] [39] Heterotrophs also allow for dephosphorylation as part of decomposition. [39] The conversion of N and S from organic form to inorganic form is a critical part of the nitrogen and sulfur cycle.
