Type 2 di­a­betes study shows bene ts of veg­e­tar­ian diet

CHECK THE COR­NERS If it looks like the colour has worn o at the cor­ners or edges, and a di er­ent-coloured metal is show­ing through, that’s a dead give­away that an item is cheap enough to let the kids play dress-up with it. WEIGH THE POS­SI­BIL­I­TIES Cheaper ma­te­ri­als used in cos­tume jew­ellery, such as cop­per and zinc, weigh more than pre­cious met­als. Weight isn’t a great in­di­ca­tor of value. A veg­e­tar­ian diet will shed twice as many pounds and re­duce more mus­cle fat than a low-calo­rie diet — a key find­ing for peo­ple with Type 2 di­a­betes — ac­cord­ing to a re­cent study in the Jour­nal of the Amer­i­can Col­lege of Nu­tri­tion.

Re­searchers ran­domly as­signed 74 peo­ple with Type 2 di­a­betes to fol­low ei­ther a veg­e­tar­ian or a con­ven­tional low-calo­rie di­a­betic diet for six months. Par­tic­i­pants in both groups had their nor­mal daily caloric in­take slashed by 500 calo­ries, on av­er­age con­sum­ing 1,500 to 1,800 calo­ries a day.

Af­ter three months, those on the veg­e­tar­ian diet shed an av­er­age of 14 pounds, com­pared with those on the low-calo­rie diet who lost seven pounds. Dur­ing the sec­ond half of the study, par­tic­i­pants stayed on their di­ets and did aer­o­bic ex­er­cise three times a week for one hour — but there was lit­tle weight loss be­cause they gained mus­cle.

Re­searchers also looked at the par­tic­i­pants’ fat stor­age tis­sue us­ing mag­netic res­o­nance imag­ing. Both di­ets re­sulted in a sim­i­lar loss of fat un­der the skin. But the veg­e­tar­ian diet more ef­fec­tively cut the fat that lines mus­cles and is stored in­side mus­cles.

This is key be­cause in Type 2 di­a­betes higher amounts of mus­cle fat is as­so­ci­ated with in­sulin re­sis­tance. But once the fat starts dis­si­pat­ing the in­sulin can work more prop­erly. Re­duc­ing mus­cle fat is also im­por­tant be­cause it in­creases with age and in­ac­tiv­ity, which can lead to de­creased mus­cu­lar strength and mo­bil­ity.

“(The veg­e­tar­ian diet) is re­ally pow­er­ful,” said the study’s lead au­thor Dr. Hana Kahleova, di­rec­tor of clin­i­cal re­search at the Physi­cians Com­mit­tee for Re­spon­si­ble Medicine in Wash­ing­ton D.C. LOOK FOR A STAMP His­tor­i­cally, cos­tume jew­ellery acted as a walk­ing ad­ver­tise­ment for it­self. If a piece has a trade name, stamp or hall­mark vis­i­ble to the naked eye, there’s a good chance it’s not go­ing to make you a mil­lion­aire. That’s changed with to­day’s brands — many con­tem­po­rary Ti any’s prod­ucts promi­nently dis­play the let­ter T, for in­stance. TAKE THE TEM­PER­A­TURE Pre­cious gems usu­ally feel very cool to the touch, while glass feels a bit warmer. Plas­tic heats up in your hand very quickly. DON’T JUDGE THE AP­PEAR­ANCE

“When you’re a pa­tient with Type 2 di­a­betes, you don’t want only a diet where you lose weight, but also a diet that will ad­dress the cause of the dis­ease.”

Among those on the veg­e­tar­ian diet, 42 per cent re­duced their med­i­ca­tions, com­pared with five per cent on the con­ven­tional diet. And three peo­ple

(The veg­e­tar­ian diet) is the only doc­u­mented diet that can ac­tu­ally re­verse di­a­betes. The study’s lead au­thor Dr. Hana Kahleova

in the veg­e­tar­ian group re­versed their Type 2 di­a­betes.

Dr. Jan Hux, the chief science of­fi­cer at Di­a­betes Canada, wasn’t in­volved in the study. While she found it in­ter­est­ing, she says it’s not de­fin­i­tive, not­ing the small sam­ple group.

Al­though weight loss was sig­nif­i­cant for the par­tic­i­pants in the veg­e­tar­ian group, she noted they also lost lean mus­cle mass, which is a con­cern. How­ever, she said the study’s find­ings that a veg­e­tar­ian diet re­duces in­sulin re­sis­tance gets at the very root prob­lem of the dis­ease.

THE AS­SO­CI­ATED PRESS

Pre­cious jew­ellery looks pre­cious from all an­gles, while cos­tume jew­ellery of­ten has hid­den parts that look pretty busted. Look at a stone set in a ring or neck­lace from the bot­tom or back. If you can see the gem through the set­ting, or there’s ma­te­rial with a rough, stip­pled or stucco tex­ture, or it looks like there’s a bit of foil or a piece of mir­ror stuck on, it’s prob­a­bly not very valu­able. The ring that was auc­tioned for more than $1 mil­lion boasts a 26-carat di­a­mond. A lot of ine jew­ellery from the past “doesn’t look nor­mal to us,” but just be­cause some­thing is “hideous” to mod­ern eyes doesn’t mean it isn’t valu­able, Parker said. He said a woman once came to him with a black­ened tiara in a plas­tic shop­ping bag, as­sum­ing it was worthless. It turned out this junk-shop ind was a tar­nished sil­ver piece that dated from Vic­to­rian times. Its weird pink gems were rare conch pearls from the Caribbean. It was worth $44,000.
