In men with coronary artery disease, substituting refined rice with whole grain and legume powder for 16 weeks raises the level of n-6 fatty acids in blood cell membranes by 14%, which changes the...
Mechanism
Synthesis from 1 study
Eating whole grains and legumes instead of white rice reduces damage to healthy fats in cell membranes. This lets more of those fats stay in place, changing how the membranes behave and how the body sends inflammation signals.
Most probable mechanism
When people eat whole grains and legumes instead of refined rice, their bodies produce fewer harmful free radicals, which protects the healthy fats in cell membranes from damage. This allows more of these healthy fats to stay in the membranes and replace other fats, making the membranes more flexible and changing how the body signals inflammation.
Dietary fiber and complex carbohydrates from whole grains and legumes slow glucose absorption, reducing postprandial insulin spikes and improving insulin sensitivity in peripheral tissues
Improved insulin sensitivity enhances cellular metabolism of homocysteine and reduces systemic oxidative stress independently of folate levels
Antioxidant compounds in whole grains and legumes, including tocopherols and carotenoids, directly neutralize reactive oxygen species that initiate lipid peroxidation
Reduced lipid peroxidation preserves polyunsaturated fatty acids in cell membranes, preventing their degradation and allowing increased incorporation of n-6 fatty acids into phospholipid structures
Increased n-6 fatty acid composition in serum phospholipids alters membrane fluidity and modulates the activity of membrane-bound enzymes involved in inflammatory signaling
