I'm new here. After 12 years of lifiting and eating right I fear I've maxed out my genetic potential. I came to this forum to LEARN nothing more, nothing less. i am a type 1 diabetic so I have a keen interest in the affects of certain substances on blood sugars. I was wondering if there are certain classes/categories of substances which either raise or lower blood sugars and most importantly if there are any which have been shown/known to not greatly affect blood sugars. i welcome any empirical or anecdotal evidence. Thank you.
