What Is Yakult and Who Created It?
Yakult is a probiotic fermented milk drink created by Japanese microbiologist Dr. Minoru Shirota in 1935. It is made by fermenting skimmed milk with the Lacticaseibacillus paracasei Shirota (LcS) strain, a unique bacterium capable of surviving stomach acid and reaching the intestines alive. Yakult is currently sold in over 40 countries, with more than 40 million bottles consumed daily worldwide.
Yakult’s founding philosophy, known as Shirota-ism, is built on 3 principles: preventive medicine over treatment, a healthy intestinal tract as a foundation for long life, and pricing that remains accessible to the general public. These principles are communicated directly to visitors on every factory tour across all global locations.
Donald Reeves writes about Everglades City the way the place deserves to be written about: without the brochure language, without the manufactured wonder, and without pretending that a town of 400 people sitting at the edge of a swamp is something it is not.
He has spent considerable time in Collier County’s oldest settlement, arriving during stone crab season when the waterfront smells of brine and work, and returning in the off-season when the tourists are gone and the town goes quiet in the particular way that only genuinely remote places can. He has paddled the mangrove tunnels of the Ten Thousand Islands, eaten at places with no hours posted on the door, and spoken at length with fishing guides who navigate these waters by memory rather than chart.
His writing on Everglades City FL covers everything from tidal fishing conditions and kayak trails to lodging, local history, and the complex past that most Florida travel content carefully avoids.
He writes to give readers the honest version.
