A vegetarian hot dog has just 56 calories and no saturated fat, and a vegetarian burger has only 70 calories, a half gram of fat and no saturated fat.
Barnard does admit that "They're not culinary art, but they're much better than what you're replacing."
Although Barnard agues that "everything we've been talking about so far qualifies as junk food," potato chips are one of the most common and ubiquitous junk foods out there.
Besides being loaded with saturated fat -- the average 1-ounce serving has a whopping 155 calories, 16 percent of which comes from saturated fat -- the potatoes from which they come are also part of the nightshade family. According to Warfield, consuming members of this family of plants has been associated in the past with increased inflammation and arthritic pain.
Barnard also believes that certain proteins in potatoes may just trigger a bad reaction in some people, quite similar to an allergic reaction. This reaction could cause painful migraines or arthritic flare-ups.
He suggests substituting sweet potatoes or yams for the white potatoes or potato chips. Although a 1-ounce serving of sweet potato chips carries about the same amount of calories as a regular potato chip, they only contain 5 percent saturated fat, which could help decrease arthritic inflammation.
However, since both chips contain about the same amount of calories and fat, just substituting a sweet potato for a white potato will not address the biggest problem with eating them -- weight gain. And Warfield says that in her experience, weight has the largest bearing on arthritis pain. So it might be better to just pass on the potato chips altogether.
