This is actually a post I've been busting to write for a while. As many of you know, I first quit sugar because of my autoimmune (AI) disease. I have Hashimoto's. And a big part of why I've stuck to the sugar-free program is that it's made such a big difference.
So the simple answer is this: Quitting sugar has had the biggest impact on my AI, more so than my medication or any other medical fix (and, trust me, I've tried everything). In the past three years, I've been able to better manage my AI, but also — yes — heal and reverse the damage.
- I have zero thyroid antibodies now.
- I'm on the most minimal dosage of thyroxine.
- My hormone levels have fallen back into the right range (more on this soon!).
It's taken years to get to this point. I put it down to the massive change to my diet that quitting sugar precipitated. And to breaking the clusterf*ck cycle that autoimmune disease invariably locks you into. But why? And how? Let me explain …
Warning: Like most of my AI and thyroid posts this is a long one. As I always remind people, even if you don't have an AI, you'll probably find it helpful because the advice I share relates to all of us.
Sugar mucks up your gut.
Blood sugar imbalances inflame the digestive tract, causing leaky gut (literally, a perforated gut lining). In turn, leaky gut triggers the development of AI. Toxins are able to pass through the perforations into the bloodstream, triggering an autoimmune reaction as our antibodies head out to attack the foreign invaders. These little antibody soldiers can then get confused and head off to attack parts of our bodies, such as the thyroid.
Sugar causes inflammation.
The process above creates inflammation, which compromises immune function. Sugar also compromises the ability of our white cells to destroy toxins. This effect begins within 30 minutes of eating the stuff, and lasts for five hours.
Insulin spikes destroy the thyroid gland.
As many of you know, sugar causes the pancreas to secrete insulin to move excess sugar from the blood into our cells, where glucose is used to produce energy. But over time, the cells lose the ability to respond to insulin. Our poor little pancreas responds by pumping out even more insulin, leading to insulin resistance.
Studies have shown that these repeated insulin surges i ncrease the destruction of the thyroid gland.
Also, this: we're programmed to see low blood sugar as a threat to survival. Thus our adrenal glands respond by secreting cortisol. Cortisol then tells the liver to increase the amount of glucose available, bringing blood sugar levels back to normal.
Cortisol is the "flight-or-fight" hormone, reserved for especially threatening situations. It causes an increase in heart rate, oxygen, and blood flow while shutting down digestion, growth and reproduction so all energy can go to our brains and muscles.
Problem is, if cortisol is overused 'n' abused (from eating sugar daily), this all suppresses pituitary function. Um, which is vital to thyroid function (the hypothalamus, thyroid and pituitary work as a threesome). And around and around and around we all go, right?
On the flip side, a bad thyroid can cause insulin issues
How's this work? Our thyroid function depends on blood sugar being kept in a normal range, and keeping our blood sugar in a normal range depends on healthy thyroid function. How so? Low thyroid function slows down the way we process sugar — in our cells, guts, the insulin response and the clearance of insulin. Which means we might even have normal levels of glucose in our blood, but because we're slow to respond to it, and to absorb it we very easily get hypoglycemic (and thus clutch at sugar). So ...
People with thyroid issues typically have a more difficult time with sugar than everyone else.
You have to break the clusterf*cky cycle yourself. It's hard to say which comes first — metabolic issues or bad thyroids … chickens or eggs. But does it really matter? At the end of the day, my friends, it all comes down to sugar. And the solution really is to quit it.
For me, I know my AI issues stem back to a sugary carb addiction in my late teens. It led to gut issues, insomnia, addictions, hormone issues, nervous disorders, adrenal collapse … and then Graves (another form of thyroid disease) … and then Hashimoto's.
The only way to break the cycle — and to eliminate both the trigger and exacerbator — is to quit sugar.
Anyway, I reckon that's enough for now. It was quite a rant. Got any further questions?
