Just wondering
 

Well today I did my weekly grocery shopping. I was in the aisle with all the salad dressings and all the other condiments. Then I remembered that I ran out of mayo. Lately I’ve been doing this thing where every time I buy some kind of food in the grocery store I have to turn it around and read the label.. even if I already know the carb count. I didn’t realize that I had picked up the jar of low fat may until I read the label and I found out it had something like 2 g of carbs. My question is why does regular mayo have 0g of carbs while the low fat has 2g of carbs?

In replacing the fat, starchy thickeners and sweeteners are used.

thanks!!!
that clears up a lot
