Apparently with the news that came out last week on walking to increase oxygen to the brain and warding off dementia. Is it true? I have my doubts. I’d like to believe it, being I do walk 30 minutes a day, and it does make sense, but there has to be other things to effect the brain as: food, preservatives, fats, etc. I recently read two articles on fat and the brain. One said to eat fat, good fat that is, not fried foods. The other said high cholesterol played a part in the development of dementia/Alzheimer’s. Which do we believe? Babies need fat, 40 percent breast milk is fat, which babies need to grow their brains. And I wonder as we age and revert back to being babies do we not need fat for our brains? Just a thought?
