Enteral nutrition is administered through a feeding tube or it can be taken orally. Fresenius owns 32% of Fresenius Medical Center, which saw shares drop on recent news that Ozempic's kidney disease treatment trial showed signs of success. Clinical nutrition is about 20% of group profits and an important subset of its larger specialized nutrition unit, Ackerman said. "Many investors only focus only on their infant formula unit and don't know how big or how profitable clinical nutrition is," he said. "Clinical nutrition is the jewel in Danone's crown and probably the most attractive part of Danone's portfolio, yet is hidden from investors."
