I've learned a lot over the years. Juvenile diabetics can learn to sense their own sugar levels by developing body awareness. This makes it much less likely to eat when sugar levels exceed 200, thus driving them up to the 300's and creating lots of ketones, or to allow low blood sugars, with the negative effect of eating too much too fast and having an upswing. I have maintained a high nutrient diet, especially easily assimilable minerals, for decades, and blood sugar swings have been minimal. Juvenile diabetics need to constantly move their bodies.
Hard work is excellent medicine.
Advanced pranayama or qi kung exercises, in which qi is made to move or flow with strong diaphramatic control, improves the general circulation a lot. Aspartame sometimes raises blood sugar in diabetics worse than pure cane sugar. God know why. 1-2 grams of concentrated powder TID, even useful long term. This includes herbs like salvia, red peony, carthamus, cnidium, bilberry, turmeric, bromelain.
