The Hidden Gut Signal That Could Be Affecting Your Mood (And Why Pre-Cut Foods Aren’t as Harmless as They Look)

Most people are looking in the wrong place when it comes to mood.
If you’re feeling anxious, off, not sleeping well, or just not quite like yourself, the focus almost always goes to the brain.
And for a lot of people, that’s where the conversation ends.
But here’s what I want you to understand.
That’s not where the story starts.
Because one of the most common patterns I see is this:
Someone is doing all the “right” things.
They’ve cleaned up their diet.
They’ve tried the supplements.
They’ve had the conversations.
And yet… something still feels off.
Not dramatically. Just enough that they know they’re not operating the way they used to.
That’s usually your clue.
Because when things feel subtly off, there’s often a signal coming from somewhere that hasn’t been looked at yet.
Your Gut Is Sending Signals — All Day Long
Your gut, your immune system, and your brain are constantly communicating.
Not occasionally.
Not just when something is wrong.
All day, every day.
A large part of that communication happens through the vagus nerve — which acts as a direct connection between your gut and your brain.
And here’s the part most people don’t realize:
Most of that communication is actually going from the gut to the brain.
Not the other way around.
So your gut isn’t just responding.
It’s informing.
Let’s Talk About a Signal Most People Have Never Heard Of
There’s something called lipopolysaccharides (LPS).
You don’t need to remember the name. But you do need to understand what it does.
LPS is a byproduct of certain bacteria.
And your immune system?
It pays attention to it.
When LPS crosses into circulation, your body doesn’t ignore it.
It responds.
And that response is inflammation.
Not loud. Not dramatic.
But steady enough to influence how your body functions — including your brain.
Here’s Where This Gets More Relevant Than Most People Expect
Let’s talk about something very normal.
Pre-cut vegetables.
You know the ones:
• bagged broccoli
• chopped onions
• baby carrots
• prepped “ready-to-cook” containers
You open them a couple days later and they feel… a little slick.
Maybe slightly slimy.
Most people think:
“I’ll just rinse them.”
You can’t rinse this away.
That texture isn’t random.
It’s bacterial activity.
And more importantly — it’s what those bacteria have already produced as the food sits.
One of those byproducts?
LPS.
And once it’s there…
it’s already part of what you’re eating.

Now Before This Turns Into Food Fear — Let’s Ground This
Your body is designed to handle bacteria.
You are not fragile.
But you are responsive.
And this is where most people miss the nuance.
It’s not about one food.
It’s about patterns.
Because when pre-cut, pre-prepped foods become a regular habit — foods that are sitting longer and starting to break down —
you are increasing your exposure to bacterial byproducts on a consistent basis.
Not once in a while.
Regularly.
And your immune system is responding to that whether you feel it immediately or not.
Why This Changes How You Feel
Because inflammation doesn’t just stay in the body.
It changes how your brain functions.
It influences:
• how neurotransmitters are produced
• how your brain responds to stress
• how stable or reactive your mood feels
So instead of feeling clear and steady, you might feel:
• more on edge
• quicker to react
• mentally foggy
• not quite like yourself
Not dramatic.
Just enough that something feels… off.
And that’s usually the most frustrating kind.
Because there’s no obvious reason.
What This Looks Like In Real Life
You’re eating relatively “healthy.
”You’re trying to make good choices.
You’re doing what feels manageable in a busy life.
But you still feel:
• a little foggy
• more reactive than usual
• not as clear or steady as you used to be
And there’s no obvious reason.
Because no one is pointing out the less obvious inputs.
I’ve seen this play out in real life more than once.
I had a client who came to me dealing with significant gut issues, brain fog, memory struggles, and a high level of reactivity to foods (histamine). They had also been navigating depression and just didn’t feel like themselves for quite some time.
They were doing what most people would consider “all the right things.” Making healthier choices. Reaching for vegetables. Trying to keep things simple.
When we reviewed their stool test, one thing stood out:
Their LPS levels were very elevated.
So we started looking at patterns.
Not just what they were eating — but how their food was showing up day to day.
And one of the consistent habits?
Bagged baby carrots.
Something they were eating regularly, thinking it was a healthy, easy option — dipping them in hummus, grabbing them on the go.
But those “baby” carrots aren’t actually baby carrots.
They’re larger carrots that have been cut down, processed, and stored — often long enough to start breaking down.
Which means more bacterial activity.
And more exposure to the byproducts that come with it.
When we removed that consistent source and supported the gut, things started to shift.
Not overnight.
But the brain fog improved.
The reactivity started to calm down.
And they began to feel more like themselves again.
Not because of one single food.
But because we reduced a consistent source of stress their body had been dealing with every day.
Why This Actually Matters
Higher levels of LPS in the body have been associated with:
• increased inflammation
• changes in blood sugar regulation
• more stress response activation
• shifts in neurotransmitter balance
• and changes in mood, clarity, and emotional stability
And here’s something most people don’t realize:
LPS is one of the compounds involved in the inflammatory cascade seen in sepsis.
Now — that does NOT mean eating pre-cut vegetables causes sepsis.
But it does give you context for how seriously your body takes this signal.
This is not a neutral compound.

So What Do You Actually Do With This?
This isn’t about perfection.
It’s about awareness.
And small shifts that change the overall load your body is dealing with.
Simple things like:
• buying whole vegetables and cutting them fresh when you can
• paying attention to texture (if it’s slimy, it’s past the point)
• not relying on pre-prepped foods as a daily default
Not because you need to be extreme.
But because your body is responding to what you consistently give it.
The Takeaway
If you’ve been feeling off — even subtly — and haven’t found clear answers…
It may not be about your brain.
It may be about the signals your body is processing every single day.
And once you understand that…
you start making different choices — without needing to overhaul your entire life.
