Do onions and celery have any nutritional value?

Onions and celery do have nutritional value. Onions are a source of vitamin C, B6, Folate, and potassium. Celery brings Vitamin K, A, C, and Folate though to be honest, there isn’t a ton of vitamin C in celery and there is quite a bit of sodium.

Foods that offer little to no nutritional value are things like chips, pretzels, soda pop, candy, and things made with white flour.

And as Gailcalled drilled into my head, poptarts have no nutritional value.

Sorry I forgot to include calories. How many calories do celery and onions have?

@LostInParadise Thanks .

Most processed snack foods, and processed desserts and a lot of processed foods such as quick ramen noodle soups have little to no nutritional value. Read more about foods with little or no nutritional value here: https://abmachinesguide.com/foods-with-no-nutritional-value/

Celery though I’ve always heard that it’s one of the least nutritous along with Iceberg lettuce

I’m sorry I didn’t read the detail part of the question.

-corn, wheat, rice, least nutritious I’m not sure if that’a a fact or not.
