Thank you for joining me.
On February, 8, 2012, my father passed away.
The truth is that was the day his heart stopped beating.
For all intents and purposes, my father had died years earlier.
It started with memory lapses,
and as time went on, his memory failed more and more,
and it got to the point where he didn't know
his own kids who came in to see him.
His personality changed,
and his ability to take care of himself was completely gone.
And...
If you could make a list of all the things that could ever happen to you,
the very last thing on your list, at the very bottom of the list,
the thing you want the least is Alzheimer's disease,
because when you lose your memory, you lose everything.
You lose everyone who ever mattered to you.
If you could look into the brain of a person who has this disease,
what you see is, between the brain cells are these unusual looking structures.
Beta-amyloid protein comes out of the cells,
and it accumulates in these little meatball-like structures
that are in front of you, on a microscopic slide.
They shouldn't be there,
and they are a hallmark of Alzheimer's disease.
This disease affects about half of Americans by their mid 80s.
You could say to your doctor,
"OK, I don't want that. What can I do to stop that?"
Your doctor will say, "Well, its old age and it's genetics."
There's a gene - it's called the APOE-[epsilon]4 allele.
If you have this gene from one parent, your risk is tripled;
if you got it from both parents,
your risk is 10 to 15 times higher than it was before.
What's the answer? Get new parents?
No, I don't think so. That's not it.
So, I'm sorry: it's old age, it's genes, period, that's it;
there's not a darn thing you can do just wait for it to happen.
Or maybe not.
In Chicago, researchers started something called
the Chicago Health and Ageing Project.
What they did was they looked at what people in Chicago were eating.
They did very careful dietary records in hundreds and hundreds of people,
and then they started to see who, as the years go by,
stayed mentally clear, and who developed dementia.
The first thing they keyed in on
was something that I knew about as a kid growing up in Fargo, North Dakota -
My mom had five kids, we would run down to the kitchen to the smell of bacon.
My mom would take a fork,
and she'd stick it into the frying pan and pull the hot bacon strips out
and put them on a paper towel to cool down,
and when all the bacon was out of the pan, she would carefully lift up that hot pan
and pour the grease into a jar to save it -
that's good bacon grease, you don't want to lose that!
My mother would take that jar,
and she would put it
not in the refrigerator but she'd put it on the shelf,
because my mother knew that as bacon grease cools down,
what happens to it?
It solidifies.
And the fact that it's solid at room temperature
is a sign that bacon grease is loaded with saturated fat, bad fat.
We've known for a long time that that raises cholesterol,
and there's a lot of in bacon grease.
And by the way, the next day,
she'd spoon it back into the frying pan and fry eggs in it;
it's amazing any of her children lived to adulthood.
That's the way we lived.
The number one source of saturated fat is actually not bacon,
it's dairy products, cheese, and milk, and so forth;
