: I am a young 58 year man and very active, but needed to shed some pounds.
I therefore decided to do a carb diet and bought the artificial sugars, such as splenda, equal etc. I then developed itching and swelling to my hands, feet and upper body. I noticed after several times of using the artificial sweetners in a one month period, that this was the cause of my itching and swelling. It has not re-occurred.
