Citando:
""Escherichia-Shigella, um grupo de bactérias que inclui patógenos conhecidos, foi encontrado na maioria das amostras de maçãs convencionais, mas não em maçãs orgânicas. Para os Lactobacilli benéficos aconteceu o oposto“.

Além disso, “metilbactérias, conhecidas por melhorar a biossíntese de compostos com sabor a morango, foram significativamente mais abundantes em maçãs orgânicas, especialmente em amostras de casca e conteúdo, que em geral tinham uma microbiota mais diversa do que sementes, caule ou cálice”."

Citando:
"Conclusions In this large observational prospective study, higher consumption of ultra-processed foods was associated with higher risks of cardiovascular, coronary heart, and cerebrovascular diseases. These results need to be confirmed in other populations and settings, and causality remains to be established. Various factors in processing, such as nutritional composition of the final product, additives, contact materials, and neoformed contaminants might play a role in these associations, and further studies are needed to understand better the relative contributions. Meanwhile, public health authorities in several countries have recently started to promote unprocessed or minimally processed foods and to recommend limiting the consumption of ultra-processed foods.

Study registration ClinicalTrials.gov NCT03335644."

"It comes after a new study found that bacon and sausages fuel cancer twice as much as previously thought.

Just 25g of processed meat daily – equal to one rasher or 2/3 of a banger – raises the risk of bowel tumours by a fifth.

The World Health Organisation previously warned 50g of processed meat a day – two rashers or 1½ bangers – increased the risk of bowel cancer by 18 per cent.

But researchers from the University of Oxford now say a mere 25g each day is enough to raise the risk by 20 per cent."
