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).
Fructose in Apples. The amount of fructose in an apple depends on its size. A single, medium-sized, raw apple -- approximately 3 inches in diameter -- contains approximately 11 grams of fructose. A small apple, at 2 and three-quarter inches in diameter, contains 9 grams of fructose, while a large apple -- 3 and one-quarter inches in diameter -- contains 13 grams. Misconceptions Compared to candy or a can of soda, a fructose-filled apple seems like the better choice.
