Delayed food reactions are real — even if your doctor hasn’t mentioned them.
Spoiler: If you only test for IgE, you're missing the slower, sneakier immune responses.
Here’s something new: Recent research found a strong link between elevated food specific IgG antibodies and markers of intestinal barrier damage — notably anti LPS and anti occludin antibodies. PMC
In other words: When your gut lining loosens (aka “leaky gut”), your immune system may generate IgG antibodies to foods you eat often — and those antibodies correlate with the compromised barrier.
What that means for you:
• If you’re regularly eating foods you tolerate but still feel off (bloating, fatigue, brain fog, joint aches) — the issue may not be just the food itself, but how your gut is processing it.
• Foods you eat frequently might build up immune complexes — not easily flushed out — especially when your gut barrier is weakened. This creates a “slow burn” of inflammation.
• Most people talk about IgG tests as one and done. But the bigger story: gut barrier support + reducing chronic exposure may matter before or alongside any food elimination.
💡 Quick check in for you:
• Did you grow up eating the same “healthy staples” over and over (yogurt, whole grain bread, almond milk, smoothie bowls)?
• Do you notice symptoms not right after eating, but later (next day, 48+ hours)?
• Have you focused on diet clean ups but skipped gut barrier / digestive system repair?
If yes → you might be dealing with delayed reactions amplified by gut barrier breakdown, not just “one rogue food”.

I’m opening with limited spots for Health Strategy Session where we look at: your symptom pattern, gut barrier health, and whether a food specific IgG profile can actually work for you — not just because you heard about it, but because your body is signaling it might be worth it.
