Good morning and hello. This is Dr. Deb
0:02
Ford, dietician and doctor of clinical
0:04
nutrition. And today we're going to dive
0:07
into a real honest discussion about one
0:10
of the most prescribed category of drugs
0:13
in America. SSRIs,
0:17
that stands for selective serotonin
0:19
uptake inhibitors. It's been in the news
0:22
a lot lately, and I thought we should
0:24
cover it. Now, you may not recognize
0:28
that technical term, but I guarantee
0:30
you've heard the brand names. Prozac,
0:32
Zoloft, Lexapro, Paxel, Selexa. These
0:36
little pills are taken by millions of
0:38
people every single day, often with the
0:42
hope of easing depression or anxiety,
0:46
calming intrusive thoughts, or lifting
0:49
that heavy dark cloud. According to the
0:52
CDC, about 13% of adults in the US
0:56
reporting taking an anti-depressant
0:59
sometime in the last 30 days. That's one
1:02
in eight of us, according to the CDC in
1:04
2020. And those numbers climbed higher
1:08
in women, especially after age 60, when
1:11
nearly 1 in4 is on an anti-depressant.
1:16
Clearly, these medications are touching
1:18
lives everywhere. And to be fair, SSRI
1:21
can help. They can save lives,
1:23
especially for people in the depths of
1:26
deep depression. But just like the
1:28
proton pump inhibitors, like we
1:30
discussed in another episode, or like in
1:33
Tylenol, the story is much more
1:36
complicated than just good pill, bad
1:38
pill. So today I want to walk with you
1:42
through what SSRIs are, how they work,
1:46
what the science says about their
1:47
benefits and their risks, and then most
1:50
importantly, how we can approach mood
1:54
health through the eyes of functional
1:56
nutrition because nutrition can be a
2:00
piece of the puzzle. Medication is not
2:03
the whole picture. So how do SSRIs work?
2:08
They're designed to increase the amount
2:10
of serotonin available in the brain.
2:14
They do this by blocking the re-uptake
2:17
pump, little mechanism that normally
2:20
clears serotonin out of the syninnapse
2:22
between these two little neurons. So
2:24
instead of serotonin being pulled back
2:27
inside the cell, it hangs out there a
2:30
little bit longer sending more signals.
2:33
This mechanism is based on the serotonin
2:37
deficiency theory of depression. The
2:39
idea that people who are depressed
2:42
simply have low serotonin. But here's
2:45
the kicker. The more recent research
2:48
shows that this theory is at least an
2:52
oversimplification.
2:54
In 2022, an umbrella review by Molecular
2:58
Psychiatry found little or no evidence
3:02
that people with depression consistently
3:06
had lower serotonin levels.
3:09
Okay. So, while SSRAs clearly do change
3:12
brain chemistry, the chemical imbalance
3:15
story we've been told for decades
3:17
doesn't hold up. There is no such thing
3:20
as a chemical imbalance. According to
3:23
the latest science, science is always
3:26
learning. So should we. So the benefits
3:29
of SSRIs, we got to be fair. SSRIs can
3:33
help. They are most effective for
3:36
moderate to severe depression. And they
3:38
can also be useful for anxiety,
3:41
obsessivecompulsive disorder, and PTSD.
3:45
There was a major metaanalysis in the
3:48
Lancet in 2018 that compared 21
3:51
different anti-depressants and concluded
3:53
that SSRIs were more effective than a
3:56
placebo in the short term. They said the
3:59
effect was modest, but the benefit was
4:03
much clearer in people with severe
4:05
symptoms than in those with mild
4:07
depression. Another benefit in some
4:09
patients SSRIs may reduce suicide risk
4:13
by lifting the floor just enough to
4:16
prevent a crisis. So there are very real
4:19
cases when drugs may make a difference.
4:21
Sometimes a life-saving difference. But
4:24
now let's look at the risks and the side
4:27
effects. As with all medications, we
4:30
have to look at the whole picture. SSRIs
4:32
do not come without risks. Common side
4:36
effects that many patients experience
4:38
include nausea, headaches, fatigue, or
4:42
insomnia. But the big one, sexual
4:45
dysfunction. Up to 60% of people on
4:48
SSRIs report decreased libido or worse.
4:53
That was in CNS drugs 2015 by FAVA. For
4:56
many, this does not go away even after
5:01
going off the medication. It is
5:04
permanent.
5:05
They're also emotional blunting. People
5:08
often describe feeling flat. The
5:11
extremes of sadness may go away, but so
5:14
do the expressions of joy. So withdrawal
5:18
or discontinuation syndrome.
5:21
If you stop an SSRI suddenly, you can
5:24
get what they call brain zaps,
5:26
dizziness, irritability, flu-l like
5:28
symptoms, or rebound of depression and
5:32
anxiety. same one that was fava in 2015.
5:36
These withdrawal symptoms can last weeks
5:39
if not months and can be mistaken for a
5:42
relapse. Then there's the increased risk
5:45
of gastrointestinal bleeding, especially
5:47
if you're on NSAIDs or aspirin. That was
5:50
in the British Medical Journal. Bone
5:53
health. Long-term use has been
5:55
associated with osteoporosis and
5:57
fracture risk. Low sodium. suicidal
6:02
tendencies in youth. Now, this is the
6:04
most sobering. FDA requires a blackbox
6:08
warning that SSRIs
6:11
may increase suicidal thinking in
6:14
adolescence and young adults. Young
6:17
people's brains are not finished
6:19
maturing until they're in their mid20s.
6:22
So, how they react to this is different.
6:25
There's also agitation, hostility, and
6:28
aggression that they're looking at. In
6:31
rare cases, especially in young people,
6:34
in early treatment or during changes in
6:37
dose, SSRIs may be linked with increased
6:41
irritability or aggressive behavior. A
6:44
Swedish cohort of about 850,000 people
6:48
found a higher risk of violent crime in
6:52
those aged 15 to 24. while taking SSRIs.
6:57
That was published in 2015.
7:00
A British medical journal review of
7:03
clinical trial data also reported a
7:06
two-fold increase in aggression in
7:08
children and adolescents on
7:10
anti-depressant but not in adults. That
7:13
was Chararma British Medical Journal
7:15
2016. FDA specifically warns that
7:19
irritability, hostility, impulsivity, or
7:23
unusual behavior changes can occur,
7:26
particularly when starting, adjusting,
7:28
or discontinuing the medicines. FDA 2007
7:33
safety communication. These events are
7:36
uncommon but important to monitor and
7:40
any new or severe agitation should be
7:43
reported to a health care provider right
7:45
away rather than stopping the medication
7:48
suddenly.
7:50
You've heard a lot of this with the
7:53
school shootings and assassination
7:56
attempts. There's always been that
7:58
underlying thing that has been
8:00
discussed. So, we don't know, but it is
8:04
something that we need to pay attention
8:06
to cuz these are not small side effects,
8:08
but they are quality of life issues that
8:11
ripple through relationships, work, and
8:15
overall vitality.
8:17
So, here's where the controversy really
8:19
heats up. Are SSRIs better than a
8:22
placebo? Irving Kersh and colleagues
8:26
published a metaanalysis
8:28
in POS medicine back in 2008, showing
8:31
that for mild and moderate depression,
8:34
anti-depressants performed only slightly
8:36
better than a sugar pill. And most of
8:40
the benefits seem to come with those
8:41
with the most severe depression. Add
8:44
that to the fact that drug companies
8:46
often suppress negative studies. we're
8:49
left with maybe an inflated picture of
8:51
how well these drugs really work. So,
8:54
are SSRIs miracles? No. Are they
8:58
useless? No. The truth lies somewhere in
9:02
the middle. So, now I'm going to go at
9:05
it through my lens. Why functional
9:10
nutrition matters.
9:12
The body is designed to heal itself. How
9:17
we live, our lifestyle, our diet is just
9:21
so out of balance. Depression and
9:24
anxiety are not simply Prozac
9:26
deficiencies. They're symptoms of a
9:29
deeper imbalance. When someone comes to
9:31
me with mood concerns, I don't just ask
9:34
about the mental state. I ask about the
9:37
blood sugar balance, their sleep, the
9:39
gut health, their hormone levels, their
9:40
nutrient levels, their stress and
9:42
support systems, and their diet. Because
9:46
the brain doesn't live in isolation. It
9:50
is deeply connected to the body. It is
9:53
part of the body through the gut,
9:54
through the immune system, through the
9:56
mitochondria that powers every single
9:59
cell. First thing I look at, blood
10:03
sugar. When the blood sugar spikes and
10:05
crashes, mood's going to spike and crash
10:08
right along with it. Irritability,
10:10
anxiety, brain fog, they all can mimic
10:13
mental illness. So, I would coach my
10:17
clients to eat protein at every meal
10:20
paired with good carbs, lots of
10:24
vegetables with healthy fats for those
10:27
neurotransmitters and fiber for the gut.
10:31
That also avoids the roller coaster
10:33
highs and lows from sugar and refined
10:36
starches.
10:38
Second thing, reduce inflammation.
10:41
There's a whole body of research
10:43
pointing to depression as or at least a
10:46
part in an inflammatory condition in the
10:49
brain. So we need to look at an
10:51
anti-inflammatory diet. The foods being
10:54
berries, leafy greens, cruciferous
10:57
vegetables, turmeric, ginger, avoiding
11:00
the inflammatory drivers, those awful
11:04
seed oils, the processed food, the
11:06
alcohol, and making sure we've got
11:09
enough omega-3. 93% of us are deficient
11:14
in omega-3, especially EPA. Meta
11:17
analysis show links to improving
11:20
depression. Sublet published that in
11:23
2011. So you got to have the omega-3s to
11:27
for a lot of research in depression.
11:31
Okay. Then raw material for the
11:33
transmitters,
11:35
B6, folate, B12 for those methylation
11:38
pathways, magnesium for calming and the
11:40
serotonin receptor support, zinc for
11:43
neurotransmitters, iron for the dopamine
11:46
synthesis. If you're low in any one of
11:48
these, no pill can fix it. You've got to
11:50
nourish the pathways. Then you've got to
11:53
heal the gut. Did you know that 90% of
11:55
serotonin is made in your gut? And
11:58
you've got this vag nerve that's like a
12:01
eight-lane highway going from the gut to
12:03
the brain. A leaky gut or imbalanced
12:06
microbiome
12:07
can disrupt the mood through that gut
12:10
brain axis.
12:12
Foster
12:14
published that in the world of
12:16
gerontology in 2017. So we use
12:19
probiotics, we use prebiotic fibers,
12:21
fermented foods, sometimes even stool
12:23
testing to get the gut ecosystem back on
12:26
track. Then we want to support hormones
12:29
and stress balance. Thyroid, estrogen,
12:33
testosterone, cortisol, the stress
12:35
hormone can deplete serotonin and shrink
12:38
the hippocampus if it's elevated too
12:40
long. So we've got adaptogens like
12:44
ashwagandha, rodeiola, regular exercise
12:48
improves stress resilience, body mind
12:51
practice, meditation, prayer, breath
12:54
work, time in nature. Then we want to
12:57
boost the mitochondrial function. We're
12:59
getting deep in the weeds here, but it
13:01
is important. The brain is the most
13:03
energy hungry organ in the body. If the
13:06
mitochondria are toxic or sluggish, the
13:10
mood suffers. So we need to think CoQ10,
13:14
Lcarnitine, alpha lipoic acid. Of
13:17
course, movement. Even a daily brisk
13:20
walk is going to light up the
13:22
mitochondria. You all know how much
13:24
better you feel after a brisk walk. Then
13:27
I always would go with checking labs and
13:31
personalizing it. This is where
13:33
functional medicine really shines. We
13:36
guess. We don't guess. We test. Running
13:39
labs for serum B12, vitamin D, feritin,
13:44
magnesium, zinc, homoyine, CRP for
13:47
inflammation. I love the Dutch test to
13:50
get the rhythms of cortisol and
13:52
estrogen, testosterone. Get a gut
13:54
microbiome panel. So many things that we
13:57
can use to personalize an intervention.
14:01
Natural supports with evidence. Exercise
14:06
as effective as SSRIs for mild to
14:09
moderate depression. That was Blumenthal
14:11
clear back in 1999. Omega-3 fatty acids,
14:15
especially EPA, shows a consistent
14:18
benefit. That was Sublet in 2011. St.
14:22
John's wart, excellent for mild to
14:25
moderate depression, but you got to be
14:27
careful because it does interact with
14:29
certain medications, especially birth
14:32
control. I had David Mushelong who had
14:35
done a lot of research on St. John's
14:37
wart at Harvard. He was a guest speaker
14:40
for my group of dieticians to
14:42
integrative and functional medicine
14:44
about 10 years ago. He had just written
14:46
a book on natural approaches to
14:48
depression. His findings were that St.
14:50
John's wart was as effective
14:53
for mild to moderate depression and
14:56
sometimes severe depression under
14:58
supervision. He also in 2012 did a
15:02
research paper on SAM E that was used in
15:06
conjunction with some of these other
15:08
things because it works with the
15:09
mitochondria,
15:11
vitamin D, magnesium, B vitamins, all
15:14
essential co-actors. Some practical
15:16
advice
15:18
if you're listening and you're on an
15:20
SSRI, what you want to know is don't
15:23
stop suddenly. Work with your provider
15:26
for a tapering off plan. Make sure you
15:28
get your labs checked. B12, vitamin D,
15:31
magnesium, thyroid. Layer in functional
15:34
nutrition. Get that blood sugar balance.
15:37
Get on an anti-inflammatory diet. Heal
15:39
up the gut. Definitely get stress
15:41
management. And if you are considering
15:44
medications, weigh the risk and
15:46
benefits, but always incorporate diet
15:48
and lifestyle.
15:50
Myths I want to clear up.
15:53
SSRIs fix a serotonin imbalance. The
15:57
evidence just doesn't support that
15:59
simple theory anymore. And another one,
16:02
SSRIs are addictive. They're not
16:05
addictive in the classical sense, but
16:07
withdrawal is real and must be managed.
16:11
And the last one, everyone with
16:14
depression needs meds forever.
16:17
Not true. Many can heal through root
16:20
cause work. So, in conclusion,
16:25
bottom line, SSRIs can be helpful, even
16:28
life-saving for some people, but they're
16:31
not a cure, and they're not without
16:32
risk. Too often, they're used longterm
16:35
without ever asking why someone became
16:38
depressed in the first place. Sometimes,
16:41
life has its ups and downs, and a pill
16:44
that covers up may not be just the exact
16:47
right thing. Functional medicine says,
16:50
"Let's look deeper. Let's stabilize
16:52
blood sugar. Let's cool inflammation.
16:54
Let's heal the gut, replete nutrients,
16:57
manage stress, build resilience,
17:00
and maybe build community.
17:03
I just keep going back to Acharoli where
17:06
this group of people have experienced
17:09
stress like no other. And they're 100
17:11
years old and older. They've gone
17:13
through World War I, World War II, Nazi
17:16
occupation, famine, so many things.
17:20
depression? No. But boy, they have
17:23
community. Very important. You're not
17:25
deficient in Prozac. Your mood is a
17:28
reflection of the whole body, your whole
17:32
lifestyle, your whole story.
17:35
This is Dr. Deb Ford reminding you
17:37
first, do no harm, and second, always
17:40
take charge of your body, your health,
17:44
and your mind. Have a great day.
