In other words more is not always better. In ER4YT , Dr. D'Adamo mentions Fucus vesiculosus as being particularly beneficial for blood type O's. As you might recall form ER4YT , blood type O is characterized by the presence of a terminal fucose sugar on its antigen. Since bladderwrack is such excellent food source of fucose and fucose containing sugar chains, it can actually bind many of the more problematic blood type O lectins, bacteria, and microorganisms. Basically, an unwanted organism can only produce a problem for you to the degree it can attach to or anchor itself to your cells.
Lectin damage follows a similar pattern.
Recognizing this simple concept of adhesion, you will readily recognize the usefulness of the concept of anti-adhesion, or blocking strategies. The question then becomes what foods might provide an anti-adhesion advantage for your blood type. Basically, the fucose in bladderwrack can act as a false decoy, binding the unwanted blood type O environmental debris and sweeping it away before it can bind to or irritate the tissue. However, they also have additional specific blocking sugars they can place at their disposal. We have already discussed the concept of adhesion and anti-adhesion, but you might not know that this is also an area of great interest in cancer research.
