Diet

Diet is a schema.org type that dual-inherits from CreativeWork and LifestyleModification (a MedicalEntity subtype). Unlike RestrictedDiet (an enum for suitableForDiet filters), Diet is a content type for the published plan itself.

Direct properties:

dietFeatures (Text): nutritional features and what to eat / avoid.
endorsers (Organization or Person): who endorses the diet.
expertConsiderations (Text): professional caveats.
physiologicalBenefits (Text): claimed health benefits.
risks (Text): risks and contraindications.
