There is some scientific misunderstanding here - this is zillionth time I read that something bigger passes from the guts into the body. There is a leaky gut syndrome however, but I doubt it explains it all. For example higher molecular weight molecules such as protein fragments and plant miRNAs can be found circulating the blood after the meal. The accumulation of microbeads is yet another example.
