Empirical metrics such as the 10:1 carbohydrate-to-fiber ratio (and modified versions including added sugar limits) effectively identify high-quality carbohydrate products and are associated with better cardiometabolic health markers, including lower triglycerides and improved insulin sensitivity.

When choosing packaged carbohydrate-rich foods, look for the 10:1 carbohydrate-to-fiber ratio. This means for every 10 grams of total carbohydrate, there should be at least 1 gram of fiber. Modified ratios that also limit added sugars (e.g., <1g or <2g added sugar per 10g carb) are even better. This simple metric helps you avoid refined grains and added sugars while prioritizing nutrient-dense options.

ModerateSupportsMEDIUM confidence
Application of the ≤10:1 carbohydrate to fiber ratio was shown to identify healthy grain foods and their association with cardiometabolic risk factors... consumption of food products meeting the 10:1 carbohydrate/fiber ratio was associated with decreased blood triglyceride concentration, lower fasting insulin concentration, and better indexes of insulin sensitivity.
