Preventing Alzheimer’s Disease with Diet

Preventing Alzheimer’s Disease with Diet


“Preventing Alzheimer’s Disease with Diet” Up to half of Alzheimer’s cases may be
attributable to just these 7 risk factors, and that’s not including diet, just because there are
so many dietary factors that they couldn’t fit
them into their model, but they acknowledged that
diet might be another important modifiable risk
factor for Alzheimer’s disease. In particular, there is growing
evidence that dietary patterns, such as the Mediterranean diet,
are associated with lower Azheimer’s risk, as well as slower cognitive decline. But which constituents of the
Mediterranean diet are responsible?
The traditional Mediterranean diet
is a diet high in intake of vegetables, beans, fruit, and nuts,
and low in meats and dairy. When they tried to tease
out the protective components, fish consumption showed no benefit,
neither did moderate alcohol consumption. The 2 critical pieces appeared
to be vegetable consumption, and the ratio between unsaturated
fats and saturated fats, essentially plant fats
to animal fats. In studies across 11 countries,
fat consumption appeared to be most closely associated with the prevalence
of Alzheimer’s disease, with the lowest fat intake
and Alzheimer’s rates in China to the highest fat intake and
Alzheimer’s rates in the United State. But this is grouping
all fats together. Harvard researchers examined the
relationships between major fat types to cognitive change over 4 years
among 6,000 healthy older women, and found that higher saturated
fat intake was associated with a poorer trajectory
of cognition and memory. Women with the highest
saturated fat intake had 60 to 70% greater odds of
worst change on brain function. The magnitude of cognitive change
associated with saturated fat consumption was equivalent to about
6 years of aging, meaning women with the
lowest saturated fat intake had the brain function
of women 6 years younger. What if one already has Alzheimer’s, though? Previously, this group of
Columbia University researchers reported that eating
a Mediterranean-style diet was related to lower risk
for Alzheimer’s disease, but whether a Mediterranean diet—
or any diet for that matter— is associated with the
subsequent course of the disease and outcomes had yet
to be investigated… …until now. They found that adherence
to the Mediterranean diet may affect not only risk for Alzheimer
disease but also subsequent disease course: Higher adherence to the Mediterranean
diet was associated with lower mortality. And the more they adhered to the
healthier diet, the longer they lived. Within 5 years, only 20% of
those with high adherence died, with twice as many deaths in
the intermediate adherence group, and in the low diet adherence group,
within 5 years, more than half were dead, and by 10 years, 90% were gone,
80% were gone, or less than half. And by the end of the study,
the only people still alive were those with high adherence
to the healthier diet.

  1. Let's dig into what specifically this Mediterranean diet is. There's a lot of diets in the Mediterranean. I look forward to your further analysis.

  2. "…have yet to be investigated, until now."  The date on the study shown in the video was 8 years ago? It's good info still, but not "now".

  3. Doc, thank you so much for your though provoking and well produced videos. I share each one on social media. Then next time your in southern california look me up, and I'll make ya a Cruelty-free, Whole-food lunch 🙂

  4. I'm currently trying to turn a Nurse Practitioner on to your and Doc McDougall's work. Do you know of any nutritional medicine courses that are offered as continuing education hours? Thanks 🙂

  5. Excellent. No smoking, exercise, NutriBullet with Organic fruits and vegetables, low saturated fats, keep exercising the brain with problem solving tasks, nuts, dark chocolate. That's what I do to stay healthy. Hopefully it works and I get to live to be 50 years old. lol

  6. I agree 100%. The solutions aren't always in the form of a "Pill". There are brain "tricks" now scientifically proven to drastically improve cognitive functions and stimulate and regrow neurons, permanently. Dr. Richard Humphrey just released a recent video about it. You can check it at http: //bit. ly/AlzheiMer2

  7. nuts  – does the saturated fat in nuts have the same bad effect – doc greger says 1 once a day is ok but like doc macdougal says if not in shells i cannot stop eating them

  8. According to the graph @1:09, Mediterranean countries (Spain and Italy) have relatively high prevalence of Alzheimer's disease. Dont these countries follow mediterranean diets then?

  9. Did you hear what the protective components of the Mediterranean diet are?

  10. i just want to take some time today to thank you guys behind nutritionfacts.org, here on youtube. i really appreciate these videos and the work put into them. it does not go unnoticed. thanks for all you do
    🙂

  11. I would like to know what is in the "healthier diet" group of the last study? 
    The doctors think my grandmother has mild AD currently, and I would love to try helping her with diet. 

  12. Dr. Gregor, thank you so much for continuing to show us how to stay or get healthy. I quote you all the time and follow your advice so I can stick around for a long time! I use your book as a guide to keep me healthy and I also share it with my friends.

  13. Money is needed for research. But Western governments spend money on non Whites to bring them to the West to replace the indigenous peoples of the West.

  14. I don't disagree with this but it states the obvious and there are plenty of OTHER, and perhaps more important factors in developing Alzheimers. The disease pretty much has the medical community, mostly, stumped! And yet, there are tons of patchy research like those here.
