I know Peat recommends pulp-free OJ. I don't have access to good oranges all the time so store-bought OJ is convenient. However, I buy flash pasteurized OJ but the label doesn't say pulp-free. I tried to strain it through a cheese cloth but there was almost no fiber at all. So my question is, where is the fiber? It seems to digest fine, I'm just a bit confused about the pulp.
