How it works

Whole grains and legumes slow down sugar absorption, so the body needs less insulin to manage blood sugar. Over time, cells become more sensitive to insulin, and antioxidants in these foods reduce harmful molecules that damage blood vessels and tissues. This combination lowers blood sugar, insulin,...

Most probable mechanism

In Simple Terms

When whole grains and legumes replace refined rice, the fiber and complex carbs slow down how fast sugar enters the blood. This means the pancreas doesn't need to release as much insulin, and over time, the body's cells become more responsive to insulin. At the same time, antioxidants in these foods neutralize harmful molecules that damage fats in the blood and cells, which further helps insulin work better and lowers toxic byproducts in the body.

Causal chain
1

Dietary fiber and complex carbohydrates in whole grain and legume powder resist rapid enzymatic breakdown in the small intestine, delaying glucose absorption.

Verified by multiple studies
which leads to
2

Slower glucose absorption reduces postprandial spikes in blood glucose and diminishes the demand for insulin secretion from pancreatic beta cells.

Verified by multiple studies
which leads to
3

Chronic reduction in insulin secretion enhances insulin receptor sensitivity in skeletal muscle and adipose tissue, lowering fasting insulin and improving HOMA-IR.

4

Antioxidant compounds including alpha-tocopherol, retinol, and alpha-carotene from whole grains and legumes directly neutralize reactive oxygen species, reducing lipid peroxidation.

5

Reduced lipid peroxidation lowers plasma malondialdehyde and urinary 8-epi-PGF2α, decreasing oxidative damage to cell membranes and lipoproteins.

6

Improved insulin sensitivity enhances homocysteine metabolism through transsulfuration and remethylation pathways, independent of folate levels, reducing plasma homocysteine.
