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).
For example, a 3-ounce serving of lean beef or pork, or 1 slice of bacon, contains neither sugar, while chicken and turkey meat is also fructose- and lactose-free. Fish is also a good choice if you're fructose- or lactose-intolerant because fish such as salmon, catfish and many other types also lack both sugars. But many meat and fish dishes prepared with certain sauces or other, sugar-containing ingredients may contain fructose or lactose.
