Im­por­tant Di­a­betes Type Fre­quently Mis­di­ag­nosed

About five to 10 per cent of all di­a­betes in West­ern coun­tries is type 3c, which de­vel­ops when the body has trou­ble pro­duc­ing in­sulin be­cause of pan­creas dam­age due to con­di­tions such as cys­tic fi­bro­sis or pan­cre­atic can­cer. By con­trast, in the com­mon type 2 di­a­betes, the body is un­able to use in­sulin prop­erly. A Bri­tish study showed that the ma­jor­ity of type-3c di­a­betes pa­tients are di­ag­nosed with type 2 in­stead. This mat­ters be­cause type 3c gen­er­ally means worse glycemic con­trol and a more ur­gent need for in­sulin in or­der to avoid com­pli­ca­tions (e.g., dam­age to the kid­neys).

Veg­gie Nu­tri­ents Bet­ter Ab­sorbed With Oil

In an ex­per­i­ment pub­lished in the Amer­i­can Jour­nal of Clin­i­cal Nu­tri­tion, par­tic­i­pants ate salad with vary­ing amounts of soy­bean oil, a com­mon in­gre­di­ent in com­mer­cial salad dress­ings. More oil re­sulted in higher blood lev­els of sev­eral essen­tial nu­tri­ents, in­clud­ing vi­ta­min A and lutein. Th­ese nu­tri­ents came from the veg­eta­bles, but the fat in the oil helped the body ab­sorb them bet­ter. There’s no need to drown salad in dress­ing, the lead au­thor said, but a cou­ple of ta­ble­spoons’ worth of oil per day could help you get the most out of a healthy diet.

Rheuma­toid Arthri­tis Raises Risk of COPD

By com­par­ing more than 24,000 rheuma­toid arthri­tis (RA) pa­tients with con­trols, a team from Arthri­tis Re­search Canada and the Uni­ver­sity of Bri­tish Columbia dis­cov­ered that RA in­creases the like­li­hood of get­ting chronic ob­struc­tive pul­monary dis­ease (COPD) by 47 per cent. That’s be­cause in­flam­ma­tion plays a role in COPD devel­op­ment. The sci­en­tists rec­om­mended that RA pa­tients min­i­mize their in­flam­ma­tion with treat­ment

(e.g., NSAIDs, bi­o­log­ics) and watch for lung symp­toms, such as wheez­ing, so that COPD can be caught in the early stages if it does arise.
