USDA says butter and cream are "empty calories". Thoughts?
Back story: I had to do a "perfect day" nutrient analysis for my nutrition class using supertracker.usda.gov and design a day that is perfect according to them. Anyway, I fudged it of course so I can get a decent grade but when I put in butter and cream, the tracker called all of it "empty calories". I asked my (vegetarian) study buddy and she looked at me funny and said, "are you asking for real?". I said I know they aren't the most nutrient dense food but we still need fat in our diet.
So my question is, are they really empty calories? Should these types of food be avoided? I'm not a Primal nutjob but my focus is health & real food and I do want to avoid "empty calories". Thoughts? Opinions?
