Top 50 whole foods per 100g, from USDA Standard Reference and Foundation databases

Soy protein isolate ranks #1 of 50 for Aspartic acid, at 10.2G per 100g.

What These Aspartic acid Rankings Mean

This ranking surfaces the top 50 whole foods for Aspartic acid, pulled from USDA Standard Reference Legacy and Foundation databases. Those two sources intentionally exclude branded and processed entries, which keeps the list focused on raw ingredients where nutrient content reflects the food itself rather than fortification or recipe adjustments. There is no established FDA Daily Value for Aspartic acid, so amounts are reported in absolute terms (G per 100g edible portion).

At the top of the ranking sits Soy protein isolate, delivering 10.2G per 100g. The top three (Soy protein isolate, Soy protein isolate, potassium type, Egg, white, dried, stabilized, glucose reduced) together form a practical "big lever" set, foods where a single serving meaningfully moves daily intake. The visual bars beside each row scale against the top food, so you can see at a glance whether a lower-ranked food is still a strong source or a distant runner-up.

Because this page excludes branded products, it is the right tool for comparing whole-food cooking choices rather than packaged-food shopping decisions, for those, the per-food pages and the branded search tools cover the same nutrient at product level. All values are reported per 100g edible portion, which means the raw numbers can be directly compared but real-world servings differ (a 100g portion of spinach is very different from 100g of almonds by volume). The nutrition guides linked below explain how to translate % DV and per-100g figures into practical daily targets and how to read nutrition labels when comparing whole foods to their processed equivalents.
