Thanks Dr Ashish!

Thanks Abu-Hussein! Can you please provide me with the evidence for the same? Would be grateful!

For a reliable answer when comparing two intervention, the best way is to check if there are any randomised clinical trials that have been done or better still systematic reviews. Unfortunately you will have to wait several years to gain a more reliable answer to your question. Current knowledge is based on a week evidence.  

Thanks Zahid! Yes I myself had searched many databases before asking this question. Could only find two relevant scientific evidences. So wanted to know if others had sufficient evidence. Thank you so much for your answer.
