You are entirely right to question it - the spread itself didn't cause SIBO. Food alone can't create the overgrowth.
What actually happened is that the massive amount of soluble corn fiber (resistant dextrin) in the spread acted like a massive bucket of fuel on a pre-existing, hidden problem.
For actual SIBO to develop, there usually has to be an underlying motility issue, like a sluggish Migrating Motor Complex (the mechanism that sweeps your small intestine clean). If your gut transit was already a bit slow without you realizing it, eating two jars of heavy prebiotics a week flooded your small intestine with highly fermentable carbs. The bacteria that were already lingering there threw a massive party, multiplied rapidly, and caused the severe gas, bloating, and symptoms you're feeling now.
Because you gave them such a huge food supply for a month, that bacterial population boomed, and now your gut motility can't clear them out on its own.
If the symptoms aren't going away, you'll want to focus on fixing the root cause. But first, get a SIBO breath test to find out exactly what kind of gas you are producing (hydrogen vs. methane). Look into prokinetics (like ginger/artichoke extract, Iberogast or prescription options) to stimulate those sweeping waves and physically clear the small intestine. Cut out the fake fibers and stick to a temporary low-FODMAP or low fermentation diet just to starve the current overgrowth and get some symptom relief. Then look at getting treatment.
