Possible Benefits Of Cornstarch
Cornstarch is a highly processed food item. The nutritious portion in corns i.e. bran and germ are mainly removed from the corn kernels to produce cornstarch. This makes it flavourless and low in essential nutrients like fibre. However, the content of carbs and calories remain intact. This is why the benefits of cornstarch are limited.
1. It is gluten-free
Gluten sensitivity is an autoimmune disorder in which a person is sensitive to gluten found in dietary sources like wheat, cereals and barley. As corn is gluten-free, cornstarch obtained is also free of gluten, which makes for a good option for people with celiac diseases or gluten sensitivity. Caution, double-check the gluten count while buying market-based cornstarch as some may contain lower amounts of it. 
2. Provides instant energy
