How the skin microbiome is established—in particular, why the immune system does not attack these bacteria—has been little studied. Now, a team led by researchers at the University of California, San Francisco (UCSF), has shown that, to establish tolerance by the immune system, colonization of the skin by commensal bacteria occurs during the first few days after birth in mice.
Currently, the US FDA has little to no established rules for what can or cannot be labelled as “natural”.
This has led to a lot of confusion in the food industry and for consumers. Companies are essentially free to label their products as “natural”, which is often a marketing advantage. We see this in cosmetics as well, where many “natural” formulations are largely identical to their conventional ones.
Organic is a regulated term and requires certification. But there’s more confusion and less oversight with natural. Is pasteurization natural? Heat treatment? Irradiation? Mineral and vitamin additives? What will differentiate “natural” from organic?
The FDA currently considers “natural” as ‘nothing artificial or synthetic’, which means no added colours and things that you would expect to not be in food.
You can see why this leaves a lot of grey area.
Until February 10th, 2016, the US FDA wants to hear your opinions on what requirements food and its production must meet to be labelled “natural”.
