Penne

Soba Noodles
Soba Noodles edge out Penne for blood sugar stability and micronutrients, but Penne wins for hearty comfort meals and holding thick sauces.
Soba Noodles score higher due to a better micronutrient profile, lower glycemic impact, and higher satiety per calorie. Penne remains a culturally versatile comfort food but offers less nutritional density unless switched to a whole wheat variety.
You trade the comforting, sauce-holding heartiness of Penne for the lighter, steadier energy and mineral boost of Soba Noodles.
