There was once a difference in classification that a Dwarf was below 4' 10, but above 4'' a Midget being 3'- 4' at maturity. However, certainly in England the terms are seen as inter-changeable. Ironically I am good friends with a genetically short family.
Just an example. A sweet onion is about 7% sugar, in-which about 40% of that is Fructose. A white onion (or any non-sweet type) is about 5% sugar, in-which less than 40% is Fructose. The amount of Fructose you are getting from even a few ounces of onion is minute. This Fructose is also bound with the flesh (Fiber) and other forms of sugar (Sucrose and Glucose).
Complex Carbohydrates. Of the total carbohydrates contained in a 1-cup serving of yellow onions, 1.5 grams are from the complex carbohydrate dietary fiber. Dietary fiber is made up of soluble and insoluble fiber, and onions contain some of both.otal Carbohydrates. A 1-cup serving of chopped, sauteed yellow onions contains 6.84 total grams of carbohydrates. This amount supplies approximately 2 percent of the recommended daily allowance of carbohydrates for adults.
