Does any research indicate that the body absorbs more nutrients when you get THC?

This is something I've been wondering about. I read that THC dilates the blood vessels in the brain. I read that it is effective at slowing down amyloid plaque formations and tangles in the brains of Alzheimer's victims. Can't help but wonder if these things are due to THC allowing the body to absorb more nutrients from food and supplements. Does anyone know if there has been any research that would indicate this?
