Greek Yogurt - another talk of the town diet fad at the gyms nowadays. Not as if the wheel has been reinvented.
Stick to what has worked for thousands of years.
I make Fresh Yogurt twice a week from 2% Neilson milk - no preservatives, sugars, or anything else. It tastes just as good as Greek Yogurt or better - with half the cost. You can add fresh fruits and berries as you please for taste.
