Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

RINSING the dishes meticulously may be a mistake since it could get rid of valuable chemicals in the detergent, according to an Australian public health specialist.

Conor Reilly, head of the school of public health at the Queensland University of Technology, says that in Tasmania, detergent residues left in milk containers were found to add a chemical containing iodine to children's milk, and resulted in a reduction in endemic goitre, a condition caused by iodine deficiency. Similarly, the tin used in food cans and stainless steel saucepans has been found to make up for a deficiency of chromium in children's diets.

Mr Reilly warns in a report in New Scientist that an obsession with the purity of food means essential trace elements are being lost from the diets of Western societies.
