Peanut butter can "cure" chapped lips

An online health article claims various "superfoods" can "cure" various conditions such as chapped lips...


One of the claims is that peanut butter can cure chapped lips, because it is full of B vitamins and protein.

Well, even if it weren't for the fact that chapped lips (and many other conditions) can be caused by a multitude of things, the claim that eating peanut butter will cure it because of its protein and "vitamin B" content just doesn't stick factually. First of all, peanut butter is barely a "good source" (10% or more of Daily Value) of niacin, at 11% DV per 1 Tbsp serving. And there is more than one B vitamin (niacin, riboflavin, thiamin, B12, folate, etc.), but none of the other B vitamins even comes close to being a good source (a requisite for any nutrient claim, let alone a health claim) in a serving of peanut butter. Nor is it a good source of protein (just under 8% DV) per serving. They don't specify which vitamin B is allegedly the cure, but if you wanted a food that was an excellent (20% DV) or better source of niacin and protein there are many better ones, including turkey and most fish.
