Is Alzheimer’s a Lifestyle Disease?

     Recent studies have shown that changes in
lifestyle can have a measurable effect on the odds
of getting Alzheimer’s disease.

     The essence of these studies is that a diet that
includes whole foods like berries, leafy greens,
whole grains and fish result in a decreased
likelihood of developing Alzheimer’s.  These recent
studies add to the accumulating evidence that a diet
more like the Mediterranean diet and less like the
Standard American Diet (SAD) is a wise idea.  

     One diet that has received considerable
attention for its positive results in reducing the odds
of Alzheimer’s disease is the MIND diet
(Mediterranean-DASH Intervention for
Neurodegenerative Delay).  The diet’s name comes
from two diets that have similar characteristics – the
DASH diet and the Mediterranean diet.

    While the MIND diet has received the most
attention, it is not the only diet with hope for
delaying or reversing Alzheimer’s and other forms of
dementia. Other diets with common characteristics
have also reported encouraging results.

      What the MIND diet has in its favor is data
collected through a scientific methodology that gives
the findings credibility.  Longer studies based on the
MIND diet are underway and will eventually be
available. For now, results from short term studies
look promising. Results from long term will take
several years.

    Diets that have shown the best results for
delaying the onset of dementia typically include
vegetables (especially green leafy vegetables like
spinach and salad greens), nuts, berries, beans,
whole grains, fish, poultry, olive oil and one glass (4
oz.) or less of wine per day.

     Finding nutritious grains will be challenging
unless you search beyond the typical grocery store’
s cereal and bread aisles. In general whole grain
product are better unless the moniker is a disguise
for a desert (added  sugar) food.  The downside of
bread is its higher glycemic index that results from
finely milled grains.   A better choice is intact whole
grains from rolled oats, quinoa, buckwheat and
wheat berries.

    Foods these diets recommend avoiding or at
least minimizing typically include red meat,
margarine, pastries, sweets, fried foods, and most
fast food.

     One study showed that people who followed the
MIND diet lowered their risk of Alzheimer’s disease
by 54% and that people who followed the diet part of
the time still cut their risk of the disease by about
35%.

     Of course, diets like the MIND diet have value
beyond our brain function.  In other studies these
diets were also supportive of heart health, improved
immunity, less cancer, etc.

     While research results from the MIND diet are
promising, it is not the only diet with remarkable
brain health results. For example, researchers have
reported remarkable results in treating epilepsy and
schizophrenia with a
ketogenic diet that shares
many similarities with the MIND diet although higher
in fat content.

    Diet plays a part in the odds of getting dementia
and a wide range of other neurological and brain
related diseases.  However, diet is not the only
lifestyle factor implicated.  Getting a good night’s
sleep, reducing stress in life and exercise also plays
an important role.  Inherited genetics plays a part
but may be less important than previously thought
given that how genes express themselves is
affected by our lifestyle.  Hopefully the warning is
evident. If you have a family history of early onset
dementia, don’t delay making the lifestyle changes
that have the highest likelihood of protecting you.
The same advice applies to anyone wanting to
maintain the best quality of life into their 80s and
90s.

     Results from studies like the MIND diet show a
reduction in rate of brain aging that’s unmatched by
current pharmacologic therapy.  The key message
from the MIND diet study is that berries are the best
fruits. For vegetables, the best benefit is from the
lower carbohydrate cruciferous veggies (cabbage,
broccoli, cauliflower, Brussels sprouts, radishes,
etc.) and leafy greens. Nuts and seeds are also
important to brain health. Refined carbohydrates
should be eliminated.

     Interestingly, the people of Ballabgarh in
northern India have the lowest occurrence of
Alzheimer’s for any region in the world. One
possibility is that curcumin, a compound in turmeric
(a favorite spice of the region) binds to amyloid
plaque and helps prevent dementia.  Another
possibility is that lifestyle is the protective
difference.   Ballabgarh is a farming community
where most are physically active and follow a
vegetarian diet with very few being overweight.  
Research is ongoing and in time we may have a
better answer.  Till then, be alert to suspicious ads
promoting amazing Alzheimer’s cures that may be
little more than over priced turmeric.

    The essential message - don’t let yourself fall
into the habit of eating a Completely Refined And
Processed (CRAP) diet.  For all, and especially the
elderly, a diet like the MIND diet is beneficial for
brain health. Clinging to a diet that is low in micro
nutrients and overly weighted toward sugar and
refined carbohydrates is not healthy.

     The diet that is best for you depends on your
needs and your ability to stick with it.
U.S. News
evaluated 38 of the most popular diets and had their
experts rate popular diets by singular objectives
(weight-loss, diabetes, heart-healthy, etc.).  If you
are looking for a diet, their guide might help you
narrow your choices. The ultimate diet will be one
that is easy to follow, nutritious, safe and effective in
helping you meet your health objectives.  If you are
currently on the Standard American Diet (SAD),
then any of their top three recommendations will be
a significant improvement.

    Before making changes in your diet, let’s have a
conversation about the appropriateness of your new
diet in meeting your needs.  As always, you are
welcome to join me for a walk and talk. What better
time to turn over a new leaf than on a beautiful fall
morning.  With the season changing and leaves
falling, you might feel the urge to turn over a lifestyle
leaf of your own.

     Last week, sunrise over the foggy mountains
gave us special treasure.  Plan to join me in
welcoming a new day and perhaps another amazing
sunrise.

                  The Oak Tree

    A mighty wind blew night and day
    It stole the oak tree's leaves away
    Then snapped its boughs and pulled its bark
    Until the oak was tired and stark

    But still the oak tree held its ground
    While other trees fell all around
    The weary wind gave up and spoke.
    How can you still be standing Oak?

    The oak tree said, I know that you
    Can break each branch of mine in two
    Carry every leaf away
    Shake my limbs, and make me sway

    But I have roots stretched in the earth
    Growing stronger since my birth
    You'll never touch them, for you see
    They are the deepest part of me

    Until today, I wasn't sure
    Of just how much I could endure
    But now I've found, with thanks to you
    I'm stronger than I ever knew

                    - Johnny Ray Ryder Jr.          





  Considering a Change in Medicare?

     Between October 15th and December 7th you
can change Medicare coverage without penalty.  If
choosing between Medicare, Medicare Advantage,
Medigap policies and prescription-drug coverage is
confusing, you aren’t alone.  For a refresher on the
primary pieces of the puzzle, Medicare provides an
excellent guide called “Medicare & You.” If already
enrolled in Medicare, the guide should have already
been delivered to your mailbox.  Otherwise you can
find the guide at
www.Medicare.gov. With plans
often changing every year, it’s wise to review your
“Annual Notice of Changes” and “Evidence of
Coverage,” which should have also been delivered
to your mailbox.

    The Medicare Plan Finder on the Medicare.gov
website is a handy tool for comparing plans. The
tool provides a list of possible health-care plans, the
costs involved, drug coverage, and customer-
satisfaction ratings. To use this web based tool you
will need your Medicare number and prescription
drugs (name and dosage).

    Each person has different needs. Often it helps
to talk with an advisor.  Two sources of free help
include the Medicare Rights Center and the State
Health Insurance Assistance Programs (SHIP).  

  • The
Medicare Rights Center is a nonprofit group
that offers a national helpline for questions about
Medicare and enrollment issues, (800) 333-4114.

 • The
State Health Insurance Assistance Programs
(SHIP) operates in all states, (800) 243-5463.
