Oh, I'd die for a glass of sugarcane juice right now in this third trimester heat! It is safe to drink, just make sure the vendor's machine is super clean, otherwise we have to deal with loose motions along with all this pregnancy fatigue!
I had some complications, so my doctor advised me to be very careful with outside drinks. Sugarcane juice has a high sugar content, so please ask your doctor first, especially if you have high blood sugar.
Yes, sugarcane juice is natural and great for energy, but please make sure it's hygienic and fresh to avoid stomach infections. If you ever get severe stomach pain or vomiting, call your doctor immediately.
I drank fresh sugarcane juice during my pregnancy to beat the heat, and it gave me instant energy! Just make sure they don't add dirty ice to it, try to have it fresh.
