Can we consume corn?

Yes, you may have corn occasionally (not more than twice a week). 

Corn is a water-poor food and is as heavy & difficult to digest as other grains. Therefore, it should be taken as a replacement for your grain meal. 

Make sure, you combine it with at least 3 times the vegetables (sabzi) to make it easier to digest. Always use fresh corn and not frozen or packaged corn available in the market.

Athletes and growing children can have it more often since they have a higher power of digestion.
