Consuming grain foods that meet a carbohydrate-to-fiber ratio of ≤10:1 is associated with significantly lower levels of cardiometabolic risk factors, specifically triacylglycerols, the triacylglycerol/HDL-c ratio, fasting insulin, and HOMA-IR.

To improve insulin sensitivity and lipid profiles, prioritize grain foods that have a carbohydrate-to-fiber ratio of 10:1 or lower. This means for every 10 grams of carbohydrates, there should be at least 1 gram of fiber. Replacing white rice and white bread with brown rice and whole wheat bread (which typically meet this ratio) significantly increases fiber, magnesium, and zinc intake while reducing total carbohydrates and added sugars.

GoodSupportsHIGH confidence
Each increase in 1% of energy (E) of these foods was associated with lower levels of blood triacylglycerol (-10.7%), the triacylglycerol/HDL-c ratio (-14.9%), fasting insulin (-13.6%), and HOMA-IR (-14.0%).

Why this rating

Based on population-based cross-sectional data with multivariable adjustments; strong association but observational design limits causal inference.
