    Digestive Tolerance & Gluten

    Soba noodles
    Spaghetti · 35Soba noodles · 85

    Pure soba is naturally gluten-free and easier to digest, while spaghetti's gluten can cause bloating for many.

    Tradeoff

    If you buy cheap soba blended with wheat, you lose the gluten-free benefit and get the worst of both worlds.

    Why it matters

    Bloating and brain fog after meals often trace back to gluten sensitivity, even if not full celiac disease.

    Swapping spaghetti for 100% buckwheat soba can mean the difference between a productive afternoon and a sluggish one.

Your move

Decision guide

Choose Spaghetti

  • You are carb-loading for an athletic event
