High resistant starch intake improves postprandial insulin and glucose regulation but may increase plasma TMAO levels, a biomarker for cardiovascular disease risk.

If you are insulin resistant, high resistant starch can help blunt blood sugar and insulin spikes after meals. However, be aware that it may also increase TMAO, a marker linked to heart disease risk in some studies. For most people, the metabolic benefits of better blood sugar control outweigh this risk, but those with existing cardiovascular issues should monitor this closely or consult a doctor.

the HRS meals produced significantly lower postprandial insulin and glucose responses... we also found that plasma levels of trimethylamine-N-oxide (TMAO), a biomarker of cardiovascular disease (CVD) risk, were higher following the HRS diet
