For today’s edition of Dear Mark, I’m answering five questions, all coming from a single reader email. First, Rosa asks about buying high-quality produce and grass-fed meat for her family on a budget. Can it be done? If not, what should she do? Second, she wonders whether she’ll get enough calcium eating this way. It’s a valid concern, seeing as how basic Primal eating often eliminates dairy. I try to assuage her. Third, if the Primal Blueprint is such a healthy, nutrient-replete lifestyle, why do I sell supplements? How does one reconcile the two seemingly contradictory concepts? Fourth, should Rosa be worrying about eating a high-fat diet if she’s taking meds for high cholesterol? And fifth, what are some effective replacements for chinups and pullups that can be done at home sans equipment?
