Grains & pasta

Grains and pasta are where the gap between a whole food and a processed one shows up most clearly. Our Nutrient Density Score rates each food from 1 to 100 on how much nutrition it delivers per calorie, and across the 60 items in this category the median lands at 64. That spread is driven almost entirely by how much of the original grain survives milling. The outer layers, the bran and germ, carry most of the fiber, magnesium, manganese, and B vitamins, while the starchy center is mostly calories.

That is why the top of this list is dominated by brans. Wheat bran, crude scores 96 and Rice bran, crude scores 93, because they concentrate the nutrient-dense part of the grain with very little of the starch. Oat bran, cooked at 87 and Rye flour, dark at 83 show the same pattern in more everyday forms you can actually cook with.

To choose well, favor whole or minimally refined grains, read for intact bran and germ, and treat white flour and refined pasta as lower-density staples rather than nutrition sources. Portion size still matters, and individual needs vary, but per calorie the less-processed grain almost always wins.
