Is it true that eating cheese without walnuts is bad for your memory?
Yes, eating cheese or walnuts alone is makrooh (not recommended).
Imam Sadiq (a.s): “Cheese and walnuts heal if they are consumed together, but cause illness if eaten separately.”
According to other narrations, it is also mustahab (recommended) to have them at night time.
Cheese is rich with calcium, and walnuts are rich in phosphorus. Our body needs phosphorus to absorb the calcium.
