Some of Steve Newport’s symptoms of Alzheimer’s disease reversed, thanks to the unlikely treatment prescribed by his wife, Dr. Mary Newport, a physician who runs a neonatology ward at a Tampa, Fla., hospital.

Dr. Newport added coconut oil to her husband Steve’s diet. Just two weeks later, he took the Alzheimer’s clock test again and demonstrated stunning improvement.

“I thought at the time, was it just good luck? Was it a lot of prayer? Was it the coconut oil?” she said. “And I thought, well, we’re going to keep the coconut oil going.”
