I was just coming at it from the point of view that in northern communities, where orange trees are not as likely to grow and there's not as likely to be as much available, that might be the right alternative, but the importance is volume. I just wanted to bring that out.
Another interesting thing I came across in my reading was that chicken eggs are used as a benchmark by which all other proteins are judged, apparently because of their better digestibility. They have a value of 100. Chicken is 79. Wheat is 60. Corn is 54.
Why is this important? Is it important?
