Source: Fried potato consumption is associated with elevated mortality: an 8-y longitudinal cohort study

Results: Of the 4400 participants, 2551 (57.9%) were women with a mean ± SD age of 61.3 ± 9.2 y. During the 8-y follow-up, 236 participants died. After adjustment for 14 potential baseline confounders, and taking those with the lowest consumption of potatoes as the reference group, participants with the highest consumption of potatoes did not show an increased risk of overall mortality (HR: 1.11; 95% CI: 0.65, 1.91). However, subgroup analyses indicated that participants who consumed fried potatoes 2–3 times/wk (HR: 1.95; 95% CI: 1.11, 3.41) and ≥3 times/wk (HR: 2.26; 95% CI: 1.15, 4.47) were at an increased risk of mortality. The consumption of unfried potatoes was not associated with an increased mortality risk.

Conclusions: The frequent consumption of fried potatoes appears to be associated with an increased mortality risk.

The abstract indicates the researchers controlled for “14 confounders”.  Note the increased mortality impact was from a subgroup analysis.  Since I’m unwilling to pay $40 USD for the full study I’ll never know if the researchers controlled for triple cheeseburgers, eggs, bacon, sausage, fried fish,  or any other foods commonly consumed with fried potatoes.
