Almost entirely mechanistic and laboratory research at this point. Ratings here are capped accordingly.
DNA integrity, cellular ageing and repair pathways.
2 foods, grouped by the strongest rating any of its claims in this area reaches. Ratings describe the research, not the food. How ratings are decided.
Early human work, or mostly lab and animal research.
Brassica oleracea var. italica
The immature flower heads and stalks of a cultivated Brassica oleracea. It is the most-studied source of glucoraphanin, the…
DNA and cellular integrity: Sulforaphane activates the phase II enzyme system, and a few human studies report faster clearance of airborne pollutants and changes in DNA damage markers. This is early biomarker work, a long way from any statement about disease.
Brassica oleracea var. gemmifera
Small axillary buds that grow along a thick stalk, another cultivar of Brassica oleracea. Modern varieties have been bred for…
DNA and cellular integrity: A small number of human feeding studies report changes in DNA damage markers and in the activity of phase II conjugating enzymes after several weeks of Brussels sprouts. This is preliminary biomarker research on small groups.
