| Slippery textures (e.g., okra, jello, wet noodles) | High lubrication, low friction | Feels “uncontrollable” or hard to grip; unpredictable in mouth | Serve roasted, breaded, or lightly pan-fried; add coating (breadcrumbs, sesame seeds); chill to firm; drain sauces |
| Sticky or gluey foods (e.g., peanut butter, mochi, mashed potato) | High adhesiveness / cohesiveness | Adheres to palate or teeth; overwhelming oral control demand | Serve thinner spreads or mix with crisp carriers (cracker, toast); chill before serving; use smaller portions |
| Mixed textures (e.g., soup with chunks, fruit in yogurt) | Inconsistent particle size; varied moisture | Surprise changes mid-bite can overwhelm prediction | Separate components (serve “deconstructed”); strain, purée, or blend uniformly |
| Crunchy or loud foods (e.g., chips, raw carrots) | High fracturability / acoustic crispness | Startling to auditory or oral-motor sensitivity | Offer quiet crunch: freeze-dried fruit, baked crisps; soften with dips; start with smaller bites |
| Gritty or grainy foods (e.g., protein shakes, smoothies with seeds) | Large particle size, uneven dispersal | Feels “dirty,” sandy, unpredictable | Use finer sieves or blenders; add fat or liquid to smooth; strain before serving |
| Creamy / thick foods (e.g., yogurt, pudding) | High viscosity, uniform texture | Can feel suffocating or “too enveloping” | Thin with milk/broth; offer dippable textures nearby for contrast; chill to increase firmness |
| Dry / crumbly foods (e.g., muffins, crackers) | Low moisture, low cohesion | Feels dusty; can trigger gag reflex | Pair with small sips of drink; add butter or dip; choose moister variants |
| Chewy / tough foods (e.g., steak, bagel) | High chewiness, high cohesiveness | Requires sustained effort; tiring | Cut smaller pieces; slow-cook or shred; use tender cuts or steamed versions |
| Fibrous / stringy foods (e.g., celery, orange membranes) | High fibrousness | Hard to break down; uncomfortable mouthfeel | Cut across fibers; choose tender sections; cook longer or serve puréed |
| Strong smells (e.g., fish, eggs, broccoli) | High odor intensity; sulfurous or fermented aroma | Triggers aversion or nausea | Serve cooler (reduces volatility); use herbs, citrus, or sweetness to balance; ventilate kitchen well |
| Spicy or “hot” foods | Chemesthetic trigeminal burn | Causes discomfort, “pain” perception | Substitute warmth with gentle flavors (ginger, cinnamon); avoid raw alliums; start mild and build tolerance |
| Cold or hot extremes | Temperature (thermal input) | Painful for sensitive nerves; shock response | Serve foods lukewarm or room temp; avoid icy or steaming extremes |
| Astringent / dry mouthfeel (e.g., unripe banana, tea) | Polyphenol-triggered dryness | Feels rough or dehydrating | Add fat or sugar; pair with creamy dips or fruit; avoid high-tannin foods |
| Strong aftertaste (e.g., coffee, dark greens) | Persistent bitter or umami compounds | Lingers unpleasantly | Serve with palate cleansers (rice, milk); balance with sweetness or acid |
| Oily / greasy foods | High fat, surface gloss | Leaves coating film; slippery aftereffect | Blot excess oil; bake instead of fry; pair with acidic sides (pickles, lemon) |
| Carbonation / fizz | Tingling chemesthesis | Feels “spiky” or intrusive | Choose flat beverages; let fizz dissipate; chill to soften bubbles |
| Visually mixed foods (e.g., casseroles, sauces with bits) | Unclear structure / unpredictable contents | Heightens anxiety over “surprises” | Present neatly separated; label ingredients; use transparent containers or clear visuals |
