Good advice. I thought I had Crohn's. Turned out I had Celiac disease. As many as 1 out of 150 people may have it.
I have Celiac disease and Ankylosing Spondylitis (spinal arthritis), but with a low-carb diet and with Remicade, I look and feel great.
The true implications of low carb and resulting low insulin are wide and far reaching. From anti aging to mental health this diet can change peoples lives. I have seen people recover from crippling anxiety that did not respond to any of the wonder drugs. I have seen people throw their antidepressants away, stop using their reflux medicine, recover from extreme allergies, cease being chronically constipated you name it.
The cascade of eicosanoids that result from a high carb omega 6 rich diet play havoc with a significant portion of our population. Between sugar and this I think prosac sales would plummet. Go to pubmed and do a search on PGE (dash)1, 2, and 3 and depression or schitzophrenia etc. The single biggest thing you can do to alter this is lower your insulin levels followed by changing the fat profile you ingest.
As far as "antiaging" diets are concerned all the rage lately is CR "calorie restricted" diets. They just don't get it however. They still try to eat low fat high carb! It is the low insulin level and the resultant increase in HGH, PGE1, PGE3, and IGF1 that makes the difference. They go about it the hard way.
The Eades and Atkins were way ahead of their time.
