De vez em quando aparece um estudo ou uma opinião contrária ao (que se tornou) senso comum: que o orgânico é muito mais saudável e que é uma agricultura mais sustentável (mas pelos vistos utiliza mais terreno cultivável - menor produtividade por metro quadrado).
Pior ainda: os alimentos sendo muito mais caros não são (de acordo com este artigo) necessariamente isentos de pesticidas (há os naturais), são mais perecíveis (tendo de ser recolhidos mais cedo quando não vendidos), são maior fonte de intoxicação (por por exemplo E. Coli) e são apenas marginalmente mais nutritivos:

"Clean eating bloggers would have you believe that eating organic will save your life and save the planet in one delicious flurry of oh-so-healthy vegetables.

She added: ‘While an organic farm may be better for things like biodiversity, farmers will need more land to grow the same amount of food.
‘And land conversion for agriculture is the leading contributor to habitat loss and climate change.’

"Perhaps the most shocking is that organic farms use pesticides – and sometimes use ones which are more toxic than the ones used by ‘normal’ farms.
(...) organic farmers can still use pesticide, they just can’t be synthetically made – and some natural pesticides are a more serious health and environmental risk than synthetic ones. Natural doesn’t always mean better.
Previous reports have highlighted the risks of toxic copper sulfate – used by some organic vegetable growers.
Organic food is alo more likely to give you food poisoning, according to ASAP science – with one study suggesting that up to 10% had traces of food poisoning bacteria E Coli.
ASAP Science says, ‘Organic food has a higher incidence of product recalls. On average 1% of food products are recalled – but 7% of organic products.’
There’s also little evidence that organic food is actually better for you – although it’s often up to 47% more expensive, according to Consumer Reports.
A 2012 Stanford study analysed 237 previous studies of organic foods and found that most here, ‘no more nutritious than conventionally grown foods’"
