🧠 探讨线粒体的重要性与功能
Dr. David Perlmutter在视频中讨论了线粒体的重要性,线粒体是细胞内的能量生产者,尤其在脑细胞中数量众多。他指出,良好的线粒体功能对于免疫反应和炎症平衡至关重要。线粒体功能障碍与多种疾病如癌症、心血管疾病以及大脑疾病如痴呆症有关。大脑作为高能耗器官,对线粒体功能依赖性高。他提出增强线粒体生物合成的方法,即增加可用于能量生产的线粒体数量,并介绍了通过检测血液中红细胞的线粒体DNA来评估线粒体数量的方法。此外,他还提到了低果糖和低钠饮食对增加线粒体密度的影响,以及这种饮食方式如何与肥胖、糖尿病、高血压等健康问题相关联。
🍽 低钠低果糖饮食对线粒体密度的影响
研究中,36名超重的前高血压成年人被分为两组,一组实行低钠饮食(每天不超过6克),另一组实行等热量的低钠低果糖饮食(每天果糖摄入量少于20克)。研究持续了八周,通过血液测试测量了白细胞中线粒体DNA的数量,以评估线粒体的密度。结果显示,仅仅实行低钠饮食就能在第八周时观察到线粒体DNA的增加,而低钠低果糖饮食组的线粒体DNA增加了70倍。研究提出,这种饮食方式通过减少氧化应激来保护线粒体,从而促进了线粒体的生成和存活。此外,研究还发现低钠低果糖饮食显著降低了氧化应激标志物dnph的水平,以及降低了尿酸水平,这与减少果糖摄入有关,因为果糖会直接提高尿酸水平。
🔬 低钠低果糖饮食与线粒体健康
Dr. David Perlmutter强调了尿酸作为氧化应激的引发因素,能够损害线粒体、影响细胞功能、增加炎症、影响一氧化氮的产生,进而影响血液供应和胰岛素敏感性。他指出,高钠和高果糖饮食会导致尿酸水平升高,这是线粒体受损的下游效应。通过八周的低钠低果糖饮食,观察到线粒体DNA在白细胞中显著增加,这表明了线粒体密度的增加。他提出,我们应采取行动帮助线粒体工作、促进线粒体再生、增强线粒体生物合成,并清除有缺陷的线粒体,这是自噬过程的一部分。最后,他总结了低钠低果糖饮食在减少氧化应激和增加线粒体密度方面的积极效果。

Dr David Perlmutter here we're going to
talk about mitochondria today
mitochondria you know the energy
producers the powerhouses within every
cell brain cells may have as many as a
thousand mitochondria in each Neuron a
mitochondria are seen diffusely
throughout the body in virtually all of
our cells interestingly not in our red
blood cells but certainly in our white
blood cells and having good
mitochondrial function and numbers
within our white blood cells is an
important player as it relates to a
proper effective immune function and
keeping inflammation in Balance we know
that mitochondrial dysfunction or
problems with the mitochondria is
something that's at the the core of some
of our most pervasive issues like cancer
and coronary artery disease
cardiovascular disease in general and
certainly as it relates to the brain and
things like dementia the brain is a very
energy hungry or organ the brain weighs
what three to five percent of the total
body weight and yet at rest may be
consuming as much as 25 percent of the
caloric expenditure of the entire body
so the brain does use a lot of energy
and as such it is highly dependent upon
functionality of the mitochondria so the
question that becomes how can we enhance
mitochondrial biogenesis what a great
term that is it simply means what can we
do to increase the number of
mitochondria that are available for
energy production and one of the
simplest measurements that can be done
to look at mitochondria involves looking
at the levels of mitochondria within the
red blood cells it's a simple blood draw
and then you evaluate actually the DNA
mitochondrial DNA which is different
from the normal cellular DNA that lives
in the white blood cells that gives you
an indication as to how many
mitochondria are present within our
white blood cells and it does serve as a
surrogate marker for us to make
Assessments in terms of what
mitochondria are doing throughout the
rest of the body
so as it turns out there is research
that demonstrates
that we can in fact increase our
mitochondrial density in this case
measured in the white blood cells and
this was an interesting study that
looked at the effect of a low fructose
and low sodium diet on the DNA that was
measured of mitochondria in white blood
cells in human subjects and again it's
really very important at least in this
study they recognize the importance of
dysfunction or problems with the
mitochondria as being a major risk
factor in things like obesity diabetes
and hypertension and because it is
related to obesity diabetes and
hypertension we then know that it is
related to the downstream issues that
are consequences of obesity and diabetes
and hypertension things like coronary
artery disease Alzheimer's disease and
even cancer are the downstream
manifestations or bro brought about when
these mechanisms are activated so we've
connected some dots then between
mitochondrial dysfunction and some of
the most important degenerative
conditions on the planet things like
heart disease and cancer and stroke for
example and certainly Alzheimer's
disease so I'd like to consider the
statement however from a different
perspective from the perspective of down
regulating mitochondria making
mitochondria less functional and how
that may have acted as what we call a
survival mechanism so when we have high
levels of fructose and or high levels of
sodium in the diet it really primes the
body or at least the bodies of our
ancestors for survival
by down regulating or making less
functional the mitochondria why because
when mitochondria are less functional we
have less energy utilization and that
can be a really powerful Advantage when
there's not a lot of food around so if
the mitochondria are not burning as much
energy it might allow survival when the
very energy that it would burn is less
abundant and in addition we know that
when mitochondrial function is
compromised it leads to the generation
of fat and that of course can be a
survival mechanism now let's look at the
nuts and bolts of the study it looked at
36 overweight
pre-hypertensive adults and put them on
either a low sodium defined as less than
or equal to six grams a day or an
isocaloric meaning the same number of
calories low sodium and low fructose
meaning less than 20 grams a day of the
fructose diet and followed these
individuals for eight weeks and compared
them to controls and it looked at the
measurement of how much DNA related to
mitochondria was seen in the blood test
which looked at the white blood cells in
a normal blood test and the study went
on for an eight week period of time
again comparing a low sodium diet
to a low sodium and low fructose diet
and what did they find
they found that with time just putting
them on a low sodium diet led to a at
week eight you see in the amber color
already the mitochondrial DNA is
starting to tick up and when you compare
that on in week eight to being on low
sodium and cutting down the fructose to
20 grams a day a dramatic increase a 70
fold increase in the mitochondrial DNA
basically the number of mitochondria in
the white blood cells that are present
now because we're sending less alarm
signals to our bodies to make fat store
fat and to ratchet down mitochondrial
function now the authors of the study
proposed a mechanism and that is that
the mechanism for protection
could relate in other words how did it
protect against damaging uh the
mitochondria to decreasing oxidative
stress as changes in oxidants parallel
the changes in mitochondrial density
what does that mean higher levels of
oxidative stress threaten the viability
the life the number of mitochondria when
you put people on a low sodium low
fructose diet you're putting them on a
lower threat a lower oxidative stress
level as it relates to their
mitochondria so more mitochondria are
created and these mitochondria survive
that's what we want what they noted in
the low sodium low fructose group this
gets a little technical but they loaded
that they noted that the level of
something called dnph
dinitrophenylhydrazine was decreased by
52 percent now that sounds pretty
scientific let me tell you what that
means that's a marker of oxidative
stress that's a marker of the damaging
action of chemicals called free radicals
it's the reason we take antioxidants in
addition and that number went down quite
dramatically the uric acid level went
down by 22 percent in people who are on
a low sodium low fructose diet why might
that be well fructose directly raises
uric acid and sodium raises uric acid a
little bit indirectly because it
increases the conversion of glucose into
fructose which then raises uric acid
that's called the polyol pathway so this
is really quite a fascinating study that
demonstrates by lowering sodium and
reducing fructose consumption there is a
dramatic effect upon the number of
mitochondria and therefore mitochondrial
function as we see with less oxidative
stress demonstrated by the reduction in
the dnph
that was an interesting study wasn't it
showed that low sodium and a low
fructose diet combined after the eight
weeks was associated with a dramatic
increase in mitochondrial density as
measured Again by the amount of
mitochondrial DNA that was found in the
white blood cells again a surrogate
marker basically for DNA of the
mitochondria throughout the body and
therefore mitochondria throughout the
body we want to do what we can to help
our mitochondria work help them
repopulate help them regrow enhance what
I mentioned earlier called mitochondrial
biogenesis meaning the growth of new
mitochondria and at the same time rid
our bodies of defective mitochondria
which is something called
mitophagy part of what the broader term
autophagy and here we've learned that a
low sodium low fructose diet is really
effective in doing that and I think you
know the area that is United by low
fructose in low sodium the mechanism
that they share is of course this
Downstream production of uric acid so we
are Upstream of uric acid we know that
uric acid is a an instigator of
oxidative stress can damage mitochondria
can compromise cellular function can
increase inflammation can compromise
nitric oxide therefore lead to poor
blood supply and at the same time a
compromises insulin sensitivity so the
downstream effects of higher levels of
sodium in the diet and higher levels of
fructose in the diet is an elevation of
the uric acid and this was a a very
dramatic demonstration a 70 fold
increase in after eight weeks of the
mitochondrial DNA in the white blood
cells very interesting information and I
think for many of you this will be quite
thought provoking hope you enjoyed our
time together today I did thanks for
joining me I'm Dr David Perlmutter bye
