THE LONDON “AS” DIET
Low starch/high protein diet for ankylosing spondylitis patients.
It is thought that in some cases a diet low in starches found in flour products and potatoes, and high in proteins and vegetables is of benefit for AS patients.
Ankylosing spondylitis is considered to be a form of “reactive arthritis” following an infection of the terminal ileum and ascending colon by the bowel microbe Klebsiella. Specific anti- Klebsiella antibodies in AS patients have now been reported from 17 different countries: England, Finland, Germany, Sweden, Netherlands, Scotland, Spain, Belgium, Slovakia, Japan, China, Australia, Canada, USA, Mexico, Argentina, and Turkey.
Over 95% of AS patients possess the HLA-B27 antigen whilst it is present only in 8% of the general population. The Klebsiella microbe has molecules which resemble HLA-B27 and this is the reason why AS patients generally belong to the HLA-B27 group.
In addition, the pullulanase molecule of the Klebsiella microbe crossreacts with type I collagen found in tendons and bone and also with type IV collagen found in basement membranes of retina and uvea, thereby explaining the pathological sites of AS.
When one eats large amounts of starchy foods (bread, potatoes, cakes and pasta), the Klebsiella bacteria feed on it, multiply and then the immune system of the patient makes antibodies against the microbe and some of those antibodies will also have activity against HLA-B27 and against collagens in the spine and uvea, thereby acting as tissue damaging autoantibodies – hence the need to ABSTAIN from these foods.
Since the mesentery of the bowel is attached to the front of the lumbar spine, it is inevitable that BACKACHE in the lumbar area will be a feature of AS.
One simple way of reducing this inflammation is to reduce the daily intake of STARCHY FOODS. However, consult your doctor before going on the diet.
The higher the intake of starchy foods, the higher the inflammatory activity.
You can eat SMALL amounts of starchy foods but it the AS is very active, it is best to eat a lot more protein and vegetables.
However, if the AS is inactive, the diet can be less rigidly followed.
Essentially, it means REDUCE BREAD, POTATOES, CAKES and PASTA and INCREASE the intake of MEAT, FISH, FRUITS and VEGETABLES.
