RE: Fresh Squeezed OJ vs. Tropicana
I'd pick a whole orange over both of them. You get the fiber and other nutrients that are lost when the orange is juiced, and juice packs quite a calorie punch vs. satiety.
If I had to choose beween the two, I'd think the o.j. with a calcium supplement of your choice would be better, as with the calcium-added juice, the calcium might sink to the bottom of the container, even with shaking.
