What's so bad about potato chips? is it okay if i eat them as a part of a balanced healthy vegan diet?

I know ....: How can something that tastes so good be so bad for you! The two big problems are fat and salt! There are 150 calories in a single serving bag of potato chips, & nearly 100 of them (2/3!) are fat. The fat in them can contribute to common problems of oily skin & acne such as you report. But I don't believe in a total ban of anything that you really enjoy: eat a single serving bag 1-2 times/week:)

A minor hazard: Despite all the hoopla about greasy, salty stuff being bad for you (and it is, though nowhere near as dangerous as smoking or loss of self-control in other areas), the most imminent danger to your health is if you are a non-supplementing vegan. If you're going to do this, please get with a scientific physician and/or dietician to learn how to stay safe -- and you can. Be discerning.
