I’ll believe it when I see it.”The former environmental attorney – who still must face confirmation by the Senate – is considered by many to be a controversial pick, given his history of making baseless health claims, including that vaccines can cause autism and that wifi technology causes cancer.Yet some of his ideas around reforming the FDA have found support from health experts, lawmakers and concerned consumers alike – including some Democrats.Kennedy “will help make America healthy again by shaking up HHS and FDA”, Colorado’s Democratic Governor Jared Polis wrote on social media this week, welcoming his nomination.

He has taken aim primarily at school lunches, telling Fox News: “We have a generation of kids who are swimming around in a toxic soup right now.”Part of Kennedy’s new mandate will include overseeing the US Food and Drug Administration (FDA), which has over 18,000 employees. The agency is in charge of ensuring the safety of pharmaceuticals and the US food supply, but has come under fire in recent years from some lawmakers and consumer groups, who have accused it of a lack of transparency and action on food safety.The 70-year-old has pledged to take a sledgehammer to the agency, and fire employees he says are part of a “corrupt system”.“There are entire departments, like the nutrition department at the FDA … that have to go, that are not doing their job,” Kennedy told MSNBC this month. He has also pushed for getting rid of food dyes, including Red No. 3, and other additives banned in other countries.The former Democrat has also singled out more controversial health issues, including fluoride in drinking water, which he says should be banned altogether, and raw milk, which he believes has health benefits despi …
