If you’ve ever sat at your kitchen table wondering,
“Why am I gaining weight when I’m barely eating?”
or
“Why does my body feel inflamed for no reason?”
There is a reason —
and it’s sitting on your plate.
Most people think hypothyroidism is just “a lazy thyroid,”
but the truth is far more frustrating:
Your thyroid is not lazy.
It’s under attack.
And some of the foods doing the attacking?
They’re foods you reach for every single day — without knowing the damage they cause.
So today we’re going to have an honest conversation — woman to woman, survivor to survivor — about the foods that quietly destroy thyroid function.
Not to scare you.
But to free you.
Because once you know better…
your healing becomes unstoppable.
🔥 1. Soy (Milk, meat substitutes, tofu, protein shakes)
Soy contains goitrogens, chemicals that literally block your thyroid from absorbing iodine — the mineral your thyroid requires to function.
What it does:
- Raises TSH
- Lowers T4/T3 conversion
- Wrecks your metabolism
- Imitates estrogen → hormone chaos
You think you’re being healthy.
Your thyroid thinks it’s being strangled.
🔥 2. Vegetable Oils (soybean, canola, corn, peanut)
These oils are in EVERYTHING.
What they cause:
Inflammation → autoimmunity → slower metabolism → stubborn belly fat
If your belly feels inflamed after eating?
It’s probably the oil, not the food.
🔥 3. Gluten
Gluten and Hashimoto’s are best friends in hell.
Science shows:
People with Hashimoto’s often produce antibodies that attack gluten and thyroid tissue… because the proteins look similar.
That means:
Your body thinks your thyroid IS gluten.
So it attacks both.
🔥 4. Conventional Dairy
Not all dairy is evil —
but processed U.S. dairy full of hormones and casein A1?
Your thyroid hates it.
This one is the cause of:
- bloating
- mucus
- inflammation
- skin issues
- slowed digestion
🔥 5. Sugar (including “healthy” sugars)
Sugar causes:
- inflammation
- blood sugar swings
- hormone imbalance
- cortisol spikes
- weight gain
And because your metabolism is already slow…
Sugar hits you harder than most people.
🔥 6. Caffeine on an Empty Stomach
This one shocks people.
Coffee first thing in the morning spikes:
- adrenaline
- cortisol
- blood sugar
- inflammation
Your thyroid does NOT like chaos at 7 AM.
Coffee is not the enemy.
The timing is.
🔥 7. Artificial Sweeteners
Aspartame, sucralose, Ace-K…
Listen.
These are poison for your thyroid.
They disrupt gut bacteria —
and 20% of thyroid hormone conversion happens in the gut.
So if your gut is dying?
Your thyroid is too.
🔥 8. Farmed Fish
Full of:
- mercury
- PCBs
- antibiotics
These chemicals lodge themselves in your thyroid tissue and disrupt hormones.
If you crave fish → choose wild-caught.
🔥 9. Corn (yes… CORN)
GMO corn is inflammatory, hard to digest, and spikes glucose.
If you feel bloated after Mexican food?
It’s the corn — not the tacos.
🔥 10. Tap Water
Full of:
- chlorine
- fluoride
- metals
- pesticides
- PFAS
Fluoride alone can drop thyroid function by 30%.
Get a filter.
Your thyroid will thank you.
🔥 11. Fast Food (even the “healthy” options)
Loaded with:
- rancid oils
- preservatives
- chemicals
- MSG
- hormone disruptors
One bite = inflammation for up to 72 hours.
🔥 12. Raw Cruciferous Vegetables
Cooked = fine.
Raw = goitrogen city.
Examples:
- kale
- broccoli
- cauliflower
- cabbage
- bok choy
Raw smoothies with kale?
Not your friend.
