Emily~ I see exactly where you are coming from concerning cheese alternatives. Daiya is the only one I will use--french_momma is right--it has no weird ingredients, is soy-free & good. But this is still a rare occassion thing for me, because I love sticking to whole foods. For that rare treat though, Daiya does not make me feel icky like dairy. (& I opt for Coconut Bliss over regular ice cream. Yum!)
I'd have to agree with meat over dairy--on both accounts, health & ethics--but only if it's free-range-organic or game. I do not agree that dairy is better from the animal's perspective. Ever been to a dairy farm? Days of quaint, small farms filled with pasture-grazing cows are long since past. Cows are not treated like cows; they are treated like milk production machines; live in dirt lots or warehouses, often in stalls with no room to even turn around; kept pregnant; denied instinct of nurturing young calves which either become veal (male), rennet for cheese or milk cows (female). They can only handle this cycle for about 5 years before production is "not profitable enough"; they either become hamburger or dog meat. A cow can live to 20 under normal conditions. Fate is the same for organic cows--most of which is owned by one company, whose factory offers no better living conditions. The animals are still slaughtered but never lived anything close to a decent life. If you do opt for cheese, I would urge you to try goat's milk cheeses as they are slightly more digestable; &, it's easier to find small farmers who care for their goats.
Take our opinions for what they are worth, but in the end, listen to your own body & mind. Live how you feel good living. Oh, & I LOVE french_momma's pizza suggestions. Much better choices for your health.
