27. The Twelve Rules of Eating (Ahara Vidhi Vidhana)

Charaka also gives a short list of rules for the act of eating itself. They are remarkably modern — warm food, proper portions, not eating before the previous meal is digested, eating calmly and attentively.

Rule	Sanskrit	Meaning	Practice for older guests
Eat warm food	Ushnam ashniyat	Warm food tastes better, kindles agni, digests easily, moves Vata downward, reduces Kapha	Food served at 60–65 °C; insulated casseroles; warm plates in winter
Eat unctuous food	Snigdham ashniyat	A little fat makes food tasty, strengthens agni, nourishes and lubricates	½ tsp ghee on rice and dal
Eat the right quantity	Matravat ashniyat	Neither too much nor too little; depends on agni	Standard portions with seconds offered, not pressed
Eat after the previous meal is digested	Jirne ashniyat	Eating on an undigested meal mixes raw and digested food	No snacking; 4–6 hours between meals; hunger as the cue
Eat compatible foods	Virya aviruddham ashniyat	Avoid opposite potencies and incompatible combinations	The viruddha guide (Ch. 20)
Eat in a pleasant place with proper utensils	Ishte deshe ishta sarvopakaranam	Calm, clean, pleasing surroundings	Quiet dining hall; clean thalis; flowers; no television
Do not eat too fast	Natidrutam ashniyat	Fast eating means poor chewing, choking risk, overeating	Seated meals; small spoonfuls; chew well
Do not eat too slowly	Nativilambitam ashniyat	Food turns cold; over-satiety; irregular digestion	Meals within about 20–30 minutes; keep food warm
Do not talk while eating	Ajalpan	Distraction, swallowing air, choking	Silence or soft conversation; the Centre may keep silent meals
Do not laugh while eating	Ahasan	Same as above — choking risk is real for elders	Calm atmosphere
Eat with attention	Tanmana bhunjita	Mind on the food	Pause before the meal; gratitude
Eat knowing yourself	Atmanam abhisamikshya	Knowing what suits one's body and state	Guests guided by intake card and prakriti

Choking safety for older diners

Sit fully upright at 90°; stay upright for 30 minutes after eating.
Small mouthfuls; finish each before the next; sip liquids between, not with food in the mouth.
Avoid talking or laughing with food in the mouth (Charaka's rules are also safety rules).
Watch for coughing, a wet or gurgly voice, or food left in the mouth — report to the duty manager and arrange a swallowing assessment.
Staff trained in first aid for choking (back blows and abdominal thrusts) should be on duty at every meal.
