Brown rice has more fiber, magnesium, and lower GI. But the difference is smaller than most think, and white rice has some advantages.
The Full Story
Brown rice: 3x more fiber (1.6g vs 0.4g), 3x more magnesium (39mg vs 12mg), GI 68 vs 73 (both medium-high). The bran contains phytic acid (reduces mineral absorption) and arsenic (brown rice has 80% more arsenic than white — arsenic concentrates in the bran). White rice: easier to digest, quicker glycogen replenishment post-workout, lower arsenic. Verdict: Brown rice for daily eating (fiber, minerals). White rice for post-workout, easy digestion, or if you eat rice occasionally. Arsenic concern is real but manageable — rinse thoroughly, cook in excess water, vary grains.
