I have always been wondering why people get drowsy and fall asleep after eating beans and custard. It happens to me and to people I know,I don't know if anyone here has experienced it because some people even call it "natural sleeping dose". Well, I am a kind of person that always wants to know "WHY WHAT HAPPENS". I have been to Google.com but I haven't found any satisfactory information about this. So now I am here because I believe so much that we have learned people here who are knowledgeable in this aspect and can help me know why this happens. What could be the cause? Thank you as u assist.

for me it's not only particularly beans and custard, it's eating any of this akara, beans, moin moin(which are all made from beans) with ogi/pap or custard....i have a weird feeling it's d amount of milk I put in it..sometimes I can use a whole tin of peak for a bowl of custard...and it knocks everybody in my house every Saturday morning.....sometimes sef my lil sister would sleep on d dinning table...no proof tho

A meal of custard and beans is rich in carbohydrates and protein and this causes a release of serotonin. Serotonin relaxes the mood and improves sleep

Another reason could be that protein like milk and beans contain tryptophan. Tryptophan improves sleep. On its own, tryptophan will not cause sleep but when eaten with carbohydrates, its effect are enhanced. Of course, you fill your custard with milk. Custard is carbohydrate, milk is protein and beans contain both carbohydrates and protein. You can see why this may be the cause.

Custard and beans is a heavy meal and your body is working overtime to digest this meal. Definitely, it takes energy to digest this food which can explain the tiredness that ensues.
