Ok. I see that protein absorption is impacted by fiber and that high fiber foods can impact the absorption of that protein. Thus if you are looking at protein sources, vegetables are not that great, except certain soy products that are also relatively low in carbs.
Being the perfectionist that I am, I usually don't use the food block method when calculating how to eat towards the zone, I usually look at the gram count.
When using the gram count method, what percentage should I use for protein from vegetables (not soy), fruit, grains and nuts?
I read on the below website: "About 98% of the protein from animal sources and about 80% of the protein from vegetable sources is absorbed by the body."
I also found the below table from the below web site:

Food source Protein digestibility (%)
Milk and cheese 97
Mixed US diet 96
Peanut butter 95
Meat and fish 94
Whole wheat 86

If I am counting protein grams (instead of blocks) the above seems like good advice, but I am more inclined to stay on the safe side of Dr. Sears recommendation for beans and legumes of 70% mentioned in the Soy Zone book.
