People with adrenal problems should not eat fruit all day and nothing else. fruit sugar is still sugar and eaten alone with no other foods for hours causes people with adrenal problems (not other people) to get worse - insulin rushes and overshoots, and low blood sugar sets in - due to the high glycemic index of watermelon and other sweet fruits when eaten alone. Seen it happen to others, had it happen to me - please don't push the all fruit thing to people with adrenal problems. It is like night and day for those who who'se adrenal problems cause hypoglycemic tendencies, and those who don't.
