What the evidence shows

Fenugreek (galactomannan-rich seed) lowers fasting and 2-h postprandial glucose and HbA1c in T2D/prediabetes (LDL & HOMA-IR null). Bread use limited by bitter/maple aroma at effective doses.

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
