The move is a far-cry from the past, when McDonald's was a seven-time sponsor of the event until the London 2012 Games - for which it said it would serve about 50,000 Big Macs, 100,000 portions of fries and 30,000 milkshakes. When Antoine de Saint-Affrique became Danone CEO in 2022, one of the first things he did was to meet with the head of the Olympic Games. "Our plant based products, yoghurts, especially those with high protein ... are extremely relevant for athletes and people who take care of their health," the company's chief financial officer Juergen Esser told Reuters in an interview.

"Obviously we will display our full portfolio including on waters to take care of hydration," he added.

Danone's Evian water brand, however, did not manage secure the deal to sell bottled water at the event, which went to long-time sponsor Coca-Cola. Its other brands include Activia yoghurts and Silk plant-based products.
