Why not. Vinegar tastes nice.
Why people feel the need to claim that things they like are also cures for a wide range of ailments I shall never understand.
Just enjoy it, and leave curing cancer to the oncologists. (The same goes for cannabis too).
Why should oncologists be the only ones getting high?
I make Pico de gallo with white wine vinegar in lieu of lime juice. I'll make a couple Mason jars of it and it will keep in the frig for a couple weeks. It's great with a simple meat or fish and rice dish.
There's as many unsubstantiated claims about certain foods being healthful as there are being harmful. It is particularly difficult to come out and claim a particular food is harmful. You better be damn sure of your findings as the industry concerned is going to come after you all teeth and claws. In this light, I'm inclined to err on the side of caution where my health is concerned. I may not get a second chance. For example, I'm not waiting for irrefutable evidence that processed meats promotes colon cancer. Seven polyps and being put on the colonoscopy three year plan is convincing enough for me to experiment with a non-processed meat diet for three years. Similarly, if one indulges in these presumed healthful foods, is there a downside should you be wrong?
