All-cause mortality is so multivariate, and so easily confounded, that an uncontrolled study of only 1,139 people in one region is meaningless. As others have pointed out, food diaries are BS. Did all 1,139 people weigh their meat before they ate it? They mention "food frequency questionnaires" ("let's see, that's 157 grams of chicken today").
