What the texts say
न नक्तं दधि भुञ्जीत न चाप्यघृतशर्करम् । नामुद्गयूषं नाक्षौद्रं नोष्णं नामलकैर्विना ॥
na naktaṁ dadhi bhuñjīta na cāpyaghṛtaśarkaram | nāmudgayūṣaṁ nākṣaudraṁ noṣṇaṁ nāmalakairvinā ||
Curd should not be eaten at night, nor without ghee and sugar, green gram soup, honey or amla, nor heated.[1]
The texts call curd abhishyandi, a food that increases secretions and blocks the body's channels. At night, they say, the channels are already sluggish and digestion is weak. The next verse warns that a 'curd lover' who ignores these rules may suffer fever, bleeding disorders, skin disease, anaemia, jaundice and giddiness.[1]
The modern view
We found no clinical studies that test whether eating curd at night causes these problems. If curd at night leaves you heavy or congested, the classical advice is easy to follow. If it does not, there is no modern evidence that you need to stop.
