Eat Veggies, save the planet

I just read in Rasmussen’s cookbook( Mark Rasmussen, author of the Veggie Works Vegan Cookbook) that it is best NOT to put vegetable skins in when you make broth. He says that it will give it an off taste. He peels his potatoes before he adds them to his broth pot.

I usually save my peelings for my broth but will try it without and see what I think.

Any opinions out there?
