Is cornstarch bad for diabetics?

My son's doctor said he has borderline diabetes and we need to reduce sugar and refined carbs. I use cornstarch sometimes for thickening gravies, so I'm wondering if it's bad for him.

Don't worry too much, but yes, cornstarch is pure refined carbohydrate and can cause rapid sugar spikes. It's usually used in small amounts for thickening, but as much as possible, try to avoid foods that contain it.

I know how exhausting it is to check every food ingredient list and feel guilty for eating. It honestly made me so anxious when I discovered how many sauces contain cornstarch. Try to take it easy, completely avoiding processed soups helps a lot.

Honestly, cornstarch is basically pure starch, bro. It has almost zero fiber and spikes glucose levels super fast. I completely cut out restaurant soups because they use it as a thickener.

I have seen many families struggle with this. Cornstarch is very high on the glycemic index, so it is indeed bad for diabetics. You can use a little bit of oat flour or almond flour to thicken your gravies instead.

Yes, cornstarch is highly refined and is definitely bad for managing blood glucose levels.

Cornstarch is pure carbs, so try to avoid it. A simple solution for thickening your gravies at home is using a paste of boiled onions or roasted chana powder instead of cornstarch.

Aloo ka powder ya cornstarch jaisi cheezein sugar ke bimar logon ke liye thik nahi hoti. Yeh khoon mein cheeni bahut jaldi badhati hain. Hamein ghar ka sadharan khana hi khana chahiye.

Ho na, gravy ghadd karne ke liye hotel wale bahut cornstarch use karte hain. Isiliye diabetes mein bahar ka khana thoda sambhal kar hi khana chahiye, ghar pe banaya toh sabse best.
