Jaw-friendly cooking: every claim and its source

This is the ledger the guides are written from. Each entry says what we claim, what that claim does not extend to, and which source it rests on. It is here so a statement can be checked one claim at a time rather than by reading an article and hoping.

Real meals made mechanically easier to eat when chewing hurts. That is a texture and eating-mechanics job rather than swallowing (dysphagia) guidance, and it is not a treatment for TMD itself.

What we say

Statements this site makes, each with the source behind it.

  1. TMD can involve jaw pain, stiffness and limited movement/locking; NIDCR includes soft foods among simple conservative measures.

    How we use it: Do not convert a self-management suggestion into a treatment claim or permanent-diet prescription.

    Sources: TMD (Temporomandibular Disorders)

    Cite this claim: https://cernere.xyz/conditions/jaw-friendly/evidence/#tmd-c01

  2. Healthdirect includes soft foods and cutting food into small pieces in self-care advice for TMJ dysfunction.

    How we use it: Do not imply the cookbook is Healthdirect's prescribed diet or a replacement for care.

  3. In Edwards et al., 66/85 (77.6%) participants reported modifying diet because of TMD; cutting food smaller was the commonest reported change.

    How we use it: Cross-sectional self-report. Supports observed behaviour, not efficacy of this cookbook.

    Cite this claim: https://cernere.xyz/conditions/jaw-friendly/evidence/#tmd-c03

  4. Food-intake difficulty is not one mechanical task; Haketa et al. assessed distinct situations in 511 people with TMD.

    How we use it: Do not turn study categories into a clinical scoring system.

  5. Diet-quality/TMD research does not establish a therapeutic diet for TMD.

    How we use it: Cross-sectional association; paper itself calls for longitudinal/intervention work. Correction changes diagnosis-frequency data. No anti-inflammatory treatment claim permitted.

  6. Thermometer endpoints follow NSW Food Authority guidance: fish 63°C, minced meat and sausages 71°C, and chicken and turkey 74°C. Leftovers are reheated to at least 60°C, which is the figure the same guidance gives.

    How we use it: These are the endpoints this project cooks to and they are the guidance figures, not a project-specific standard. Local public-health guidance differs between countries and takes precedence over anything here. Tenderness cannot be achieved by undercooking.

    • “Fish: 63ºC Minced meat, sausages: 71ºC”

      Cooking temperatures, safe internal temperatures table

      Fish endpoint, verbatim from the guidance table.

    • “Minced meat, sausages: 71ºC”

      Cooking temperatures, safe internal temperatures table

      Minced meat endpoint, verbatim.

    • “Chicken and turkey (whole), thighs, wings legs, breasts: 74ºC”

      Cooking temperatures, safe internal temperatures table

      Poultry endpoint, verbatim.

    • “Chicken and turkey (whole), thighs, wings legs, breasts: 74ºC Leftovers: 60ºC”

      Cooking temperatures, safe internal temperatures table

      The guidance minimum for leftovers, and the figure every recipe on this site now carries. An earlier version of this claim described reheating to 74°C as a project choice; no recipe did that.

    • “Using this method should ensure your meat and poultry is free from harmful bacteria, although what constitutes "pink" and "clear running juices" might differ from person to person, and colour is not always a reliable indicator.”

      Cooking temperatures, Is my food cooked?

      Why an endpoint is given at all rather than a colour cue.

  7. Food held between 5°C and 60°C for less than two hours can be refrigerated again below 5°C; between two and four hours it can be used but not returned to the fridge. The time is cumulative.

    How we use it: This is the Australian 2-hour/4-hour rule as published. Recipe-specific quality windows can be shorter and do not extend it. Nothing here certifies a particular kitchen or a particular batch of food.

    • “If your leftover food has been out of the fridge for:; less than 2 hours – use it now, or put it back in the fridge for later; between 2 and 4 hours – use it now or throw it out, and; after 4 hours, throw the food out.”

      Leftovers, and the 2-hour/4-hour rule, the 2-hour/4-hour rule (list)

      The rule as published, verbatim.

    • “Food poisoning bacteria grow best between temperatures of 5°C and 60°C - also known as the ‘temperature danger zone’. Always store leftovers at less than 5˚C and keep them separate from uncooked foods, such as raw meat.”

      Leftovers, and the 2-hour/4-hour rule, storing leftovers

      Replaces an earlier 4°C figure that no source stated. The published threshold is below 5°C.

  8. Nutrition is calculated from authoritative per-100 g composition data and is descriptive/variable by product and yield.

    How we use it: Never describe calculated values as laboratory assay of the finished recipe. Optional finishing salt/pepper is excluded.

    • The Australian Food Composition Database and AUSNUT are reference databases of per-100 g nutrient values for Australian foods, compiled from analysis, borrowed values and calculation, and intended as a reference for the nutrient content of foods rather than as an assay of any particular finished dish.

      Australian food composition databases, database description

      Names the composition spine the site computes from. It is a reference database, so a computed figure is descriptive and varies with product and yield; it is never an assay of the finished dish.

  9. Current evidence does not establish a causal or therapeutic dietary pattern for painful TMD.

    How we use it: The 2026 systematic review included only seven low-risk studies and judged findings limited, heterogeneous and insufficient for firm causal or therapeutic conclusions. Do not promote an anti-inflammatory, supplement or elimination diet as TMD treatment.

  10. TMD can affect the mechanics and experience of eating, including opening, biting and chewing, and can influence food choice and diet quality.

    How we use it: Use to explain why food adaptation can be practically relevant. It does not prove that dietary modification treats the underlying TMD.

  11. Diet advice for painful TMD can focus on eating comfort and maintaining nutritional quality, while evidence-based diet guidelines remain limited.

    How we use it: This is a practical-management boundary, not a prescribed therapeutic diet. Encourage individual clinical assessment when pain, restricted opening, swallowing difficulty, unintended weight change or inadequate intake is significant.
