Evidence

A

Highest-quality evidence in the legume group, from pooled RCT meta-analyses rather than bean-specific trials. High heterogeneity (I2=80%) and Pulse Canada co-funding.

Study dose vs. serving

Median 130 g/day (about half to three-quarters cup cooked) lowered LDL 0.17 mmol/L (~5%). Glycemic trials averaged 152 g/day. Realistic serving, though the CMAJ authors note most North Americans would need to more than double current intake.

Use caution if

You have IBS or are FODMAP-sensitive, legumes are a common trigger; start with small portions
You take levothyroxine, high-fiber meals can reduce absorption if taken too close together
