Dinner in a Foodstall

Went out for dinner today, love the Teo Cheow Fish Porridge. The porridge was a bit different from what we normally eat. The pieces rice still can be seen instead of fully mashed. Sotong kangkung and the Lala was not bad too... Yummy~ My aunty told me that diabetic patient shouldn't eat those over blended porridge. I wonder why~ Can anyone tell me?
