The seaweed in your sushi may hold a tiny helper for blood sugar

Dulse is a soft red seaweed eaten across Asia — nori in Japan, gim in Korea. Hokkaido University researchers put it through artificial digestion in the lab and found that digestion releases a tiny protein fragment, a peptide called EVYR, which slows down an enzyme that normally cuts short the body's insulin-releasing signals. Slow that enzyme, and the signals last longer — the same basic trick used by some diabetes medicines. The team, publishing in Food Bioscience, also found other red algae carry the raw material to release EVYR. More work is needed to see if a normal serving delivers enough to matter, but the seaweed aisle is looking smarter.
