Dr Vishakha Mahindroo who is an Ayurvedic practitioner clarifies, "Ayurveda depends upon three pillars - vatta, pitta and kapha. Some dals are very heavy, some moderate and others light. Consuming dal at night disturbs the bodily systems. But it basically depends on what dosha is prominent in one person and accordingly we decide what is safe for them to eat, at what time."
"In general, it is best to consume dal during daytime as whatever we eat at night should be light and easily digestible. For example, moong dal is light and easily digestible, thus, it is completely okay to have it at night. In fact moong dal helps balance the digestion process. If you are having dal at night, make sure to have it at least two-three hours before you sleep. Though yes, dal is a good source of protein, but it takes some time to digest."
