Sodium target and dietary boundary Defines what restriction means for this instance of the diet and what intake it covers.
Target definition
Captures the quantitative objective and its authority.
Explicit sodium objective
Record the intended sodium limit or reduction without filling in an unsupported default.
- What sodium limit or reduction is intended, over what interval, and with what averaging rule? definition
- Who or what established this target, when, and for which person or population? provenance
Covered intake
Defines the intake sources and neighbouring restrictions included in assessment.
Whole-diet sodium boundary
Make the coverage of foods, drinks and added ingredients explicit, and identify any separately tracked sodium sources.
- Does the intake record cover drinks, condiments, cooking salt and table salt as well as meals and snacks? boundary
- How are sodium from supplements or medicines and any separate fluid restriction handled in the governing plan? boundary
Sodium accounting Connects consumed quantities to traceable sodium estimates.
Food and recipe estimates
Establishes sodium amounts for the food actually consumed.
Normalised sodium amounts
Retain the original nutrient basis and portion assumptions behind each estimate.
- Does each source report sodium or salt, per serving or per unit mass, and what conversion is needed? measurement
- What consumed portion, recipe yield and ingredient quantities support the sodium estimate? measurement
Coverage and variability
Qualifies totals by recording completeness and variation across days.
Intake estimate confidence
Distinguish observed totals from estimates affected by missing meals, uncertain recipes or changing products.
- Which sodium contributions are measured, label-derived, database-derived, estimated or missing? provenance
- How do daily totals and recording gaps affect confidence in target attainment over the review interval? measurement
Food and meal implementation Models the concrete food choices and preparation practices used to reduce sodium.
Selection and substitution
Identifies changes to foods and ingredients using actual consumption patterns.
Priority sodium contributors
Prioritise substitutions by estimated contribution and feasibility rather than by food reputation alone.
- Which foods, drinks or ingredients contribute the most sodium at the portions and frequencies recorded? measurement
- Which available substitutions reduce estimated sodium while remaining acceptable and compatible with other dietary needs? action
Preparation and eating context
Captures control over recipes, additions and meals prepared by others.
Controllable sodium additions
Record where preparation choices can change sodium and where ingredient information or control is limited.
- How are salt, sauces, stocks and condiments added and apportioned in the meals consumed? measurement
- What ordering, portioning or preparation actions are feasible for restaurant, institutional or shared household meals? action

Concurrent requirements
Checks compatibility with other dietary and clinical instructions.
Compatible dietary plan
Keep sodium decisions linked to separately established nutritional requirements and individual constraints.
- Which other nutrient targets, allergies or clinical instructions constrain the proposed sodium-reduction choices? boundary
- Do the proposed changes preserve adequate food intake and satisfy the person's documented dietary requirements? action
Salt replacement review
Treats salt substitutes as identified ingredients requiring their own assessment.
Substitute composition and suitability
Record what replaces salt, how much is used and whether individual suitability has been established.
- What are the substitute's sodium, potassium and other relevant ingredient amounts at the intended quantity? measurement

Adherence and review Tracks whether the diet is implemented, sustainable and due for reassessment.
Implementation evidence
Assesses observed practice and barriers to maintaining it.
Attainment and feasibility
Evaluate target attainment alongside taste, cost, access and preparation burden.
- Across adequately recorded intervals, how consistently does estimated intake meet the stated sodium objective? measurement
- Which barriers explain departures from the plan, and what feasible adjustment addresses them? action
Review and outcome links
Connects dietary records to an authorised review process without treating health outcomes as proof of intake.
Review triggers and evidence
Keep dietary attainment separate from clinical observations and document who may revise the target.
- Which scheduled reviews or documented changes in circumstances trigger reassessment of the sodium target? action
- Which linked outcome observations are available, and what limits prevent attributing their changes to sodium intake alone? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
A low-sodium diet is an eating pattern that limits total dietary sodium intake, commonly to help lower blood pressure or manage conditions associated with sodium and fluid retention.
In scope
- The sodium target, its time basis, origin and intended application
- Sodium contributed by foods, drinks, cooking ingredients and table additions
- Food selection, preparation, portioning and substitutions used to implement the target
- Evidence of intake and the uncertainty of sodium estimates
- Individual constraints, nutritional adequacy and conditions for reviewing the diet
Out of scope
- Chemical identity and material properties of sodium or sodium chloride
- Diagnosis and treatment of conditions for which sodium restriction may be considered
- Manufacturing specifications and regulatory claims for individual food products
- Complete models of DASH, Mediterranean or other dietary patterns
- Independent fluid, potassium, energy or other nutrient prescriptions
Why it exists Filled
Enable an agent to recognise a low-sodium dietary pattern, assess its implementation against a stated sodium target, and identify decisions requiring individual clinical context.
Distinguishing features Filled
- An explicit sodium target or reduction objective governs the dietary pattern; a general healthy-eating intention alone is insufficient.
- Assessment covers sodium across the diet, rather than only salt added during cooking or at the table.
- A diet described as reduced-sodium has a comparison baseline; that description alone does not establish compliance with an absolute sodium target.
- A low-sodium claim on one food does not establish that the person's overall diet meets its sodium target.
- Sodium restriction is a separable constraint that can be combined with other dietary patterns and does not by itself imply fluid restriction.
What robots and AI may and may not do Filled
Must not
- Set a specific sodium limit for a person's medical condition in place of a clinician.
- Tell a person to stop or change prescribed medicines because of their diet.
- Present a food as low-sodium when its label or recipe does not support that.
- Shame people for their diet or their culture's cooking.
Only with a human decision
- Planning meals for a patient with heart failure, kidney disease or another condition needing a prescribed sodium target.
May
- Explain what a low-sodium diet is and why it is commonly recommended, citing health authorities.
- Read and report sodium or salt content from food labels.
- Suggest that a person discuss their sodium target with a doctor or dietitian.
Moral aspects Filled
- Diet advice affects health; wrong advice can harm people with heart or kidney disease.
- Sodium limits can make culturally important foods hard to eat; advice should respect that.
Who is affected
- Patients on restricted diets
- Older people
- Carers who prepare meals
Owners Filled
Steward
The person following it, usually with their clinician or dietitian; health authorities publish guidance.

- Poor adherence when food becomes unappealing.
Standards and interfaces required Filled

Context of use required Filled
- A low-sodium diet is encountered in clinical nutrition and everyday meal planning to limit total sodium intake.
- It is commonly used in managing high blood pressure and conditions involving fluid retention.
