Jeremy Lin -- I Ease The Pain Of Losing ... With a McFlurry

Jeremy Lin thinks the cure to frustration is 930 calories of frozen confectionery goodness ... telling TMZ Sports he turns to a McDonald's McFlurry to deal with the pain of a crushing Lakers loss.

Lin was at the annual Lakers Thanksgiving celebration this week to hand out turkeys to the less fortunate when we asked him if he had any guilty food pleasures ... given he's a world class athlete.

The Lakers star admitted that he recently indulged after a particularly tough loss ... and it seems the McFlurry did the trick.
