No Nuts
All other foods that did not include walnuts or other nuts were classified as "no nuts" (NN).
|
based on self report definition, fasting plasma glucose, and hemoglobin A1c
|
|
Other Nuts
Foods codes describing nuts that are not walnuts (i.e.
cashew nuts, pistachios, etc.) or nut-containing foods that do not commonly contain walnuts (e.g.
granola) were classified as "other nuts" (ON).
|
based on self report definition, fasting plasma glucose, and hemoglobin A1c
|
|
Walnuts with other nuts
food codes describing nut mixes and foods that commonly include walnuts were classified as "walnuts with other nuts" (WwON)
|
based on self report definition, fasting plasma glucose, and hemoglobin A1c
|
|
Walnuts with high certainty
Foods consisting entirely or mostly of walnuts were classified as "walnuts with high certainty" (WwHC)
|
based on self report definition, fasting plasma glucose, and hemoglobin A1c
