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).
If you are sensitive to fructose, you don't have to eliminate all fruits, but only fruits that contain more than half of their natural sugars as fructose. The high-fructose fruits you should avoid include apples, cherries, mangoes, watermelon and pears.You can safely have moderate amounts of low-fructose fruits, such as honeydew melon, cantaloupe, bananas, blueberries, strawberries and oranges, if they are well spaced throughout the day.void sweeteners that are rich in fructose, especially honey, high-fructose corn syrup and agave syrup. If you want to add a sweet touch to your diet, use lower-fructose alternatives, such as maple syrup, brown sugar, granulated sugar, stevia or artificial sweeteners, to keep your intestines happy.
