"Em 2015, e após a divulgação do estudo da IARC, o Governo francês começou por fazer uma recomendação não vinculativa contra a venda ao público do glifosato. Há poucas semanas, porém, optou pela proibição total de produtos químicos que contenham glifosato e taloamina."

Pesticidas banidos em 2013 não afectam de igual modo as abelhas - Estudo

http://www.bbc.com/news/science-environment-36154134


Citando:
"This study examined the three types banned by the EU in 2013. It shows that different types affect the brains of bumblebees in distinct ways.




Two (imidacloprid and thiamethoxam) were shown to be highly toxic to bumblebees when they were exposed to levels of the chemicals found in the countryside.
They affected their brains, impairing their memory and ability to forage for pollen. The toxic effects also included altering the make-up of the colony, changing the ratio of males to females and in some cases reducing the number of queens.
The third (clothiandin) - a close chemical relative that has not been tested before is shown not to be harmful to bees in the low doses given during field trials. The number of queens in the colonies actually increased."

Citando:
"A new study from the World Cancer Research Fund (WCRF) found an increased risk of stomach cancer for people drinking three or more alcoholic drinks a day (equivalent to more than 45g of alcohol per day).
Eating the equivalent of 50g per day of processed meat - two rashers of bacon - was also linked to stomach cancer, while being overweight or obese also increased the risk.
(...) There was also some evidence that eating citrus fruit could decrease the risk."

"Just one-and-a-half ounces of the nuts, high in polyunsaturated fats, can boost friendly bacteria in the gut which reduce inflammation and cholesterol - both of which contribute to heart disease.

They also reduce hungry and increased feeling full.

Every 28 grammes (1oz) of walnuts contains 13 grammes of polyunsaturated fat and they are the only nut with high levels of plant-based omega-3 fatty acid with 2.5 grammes per ounce serving."
