Foods are categorised into sattva, rajas and tamas based on their nature. As is stated here, tamas foods are:
Food cooked more than three hours before being eaten, which is tasteless, stale, putrid, decomposed and unclean, is food liked by people in the mode of ignorance.
This means that even curds being fermented would be categorised as Tamasic in nature as has been stated on this site. However, the dharmashastras have carved out an exception in the case of curds by stating as follows:
Among Soured Substances, the curd is fit to be eaten, and all that is prepared out of it; as also all that is distilled from pure flowers, roots and fruits;—Manu 5.10
- I would like to know whether curds are categorised as tamasic as well as the reason why the dharmashastras have carved an exception for curds. That is what is the speciality of curd that despite being fermented it is recommended to be eaten.
- What other foods though not mentioned would qualify, following the same reason as curd.
- Does curd have any harmful effects for sadhana since it is fermented? (I mean obviously if it had harmful effects, Manusmriti wouldn’t carve an exception, but still a proper reference would be good).
I have asked about certain alcohols being carved out here
