Before the conference, Biden's administration released a list of more than US$8 billion ($14b) in commitments to the cause from private companies, charitable foundations and industry groups. They range from outright donations to in-kind contributions of services and include:
• A US$20m ($35m) commitment from the Novo Nordisk pharmaceutical company to improve access to healthy foods and safe spaces for physical activity in marginalised communities.
• A US$3.85m ($6.74m) commitment from the Publix grocery store chain to supply food to local foodbanks and establish free mobile food pantries.
• US$22m ($38m) from the Danone food company to fund a programme to help "at least 300 million Americans to build healthier dietary habits".
• A commitment from the Meijer grocery store chain to offer up to a 10 per cent discount to incentivise users of the SNAP programme to buy fruits and vegetables.
Some of the conference's goals sound reminiscent of former first lady Michelle Obama's Let's Move initiative to tackle childhood obesity and promote healthy eating, highlighting the need for access to better, healthier food and exercise.
While Biden is touting the successful buy-in campaign from the private sector, some of the strongest potential obstacles to his proposals lie in the increasingly partisan Congress.
Proposed policy changes include an expansion of SNAP eligibility, expanding access to free meals in schools and extending summer meal benefits to more schoolchildren. All of those changes would require congressional approval.
