Sugar content (by percentage) of tomatoes

I tried to get this from , which was no help at all. Any help here?
(The USDA says that lemons (!), at 8.9%, have more sugar than any other fruit.)

You can find some charts that might be helpful here and here (and whoever told you that about lemons was mistaken.)

I looked at the list in the second link. I have eaten tangeloes, which aren’t on that list.

On wikipedia it says sugars: 2.6g pr. 100g. Link

Edit: Sorry, didn’t notice you wanted to know by percentage.

Yes, I did. Nutrition Facts charts on food packages show sugar content, usually in grams; this per serving size, also measured in grams. Thus a percentage can be calculated.

…And I went to the corresponding page in Wikipedia for lemons. According to lemons’ information, the sugar content is 2.5 grams per 100 grams of lemon, giving a percentage of 2.5%. The USDA figure I quoted doesn’t match that.

It seems like the USDA should know that lemons are sour.

From this paper it looks like around 1% Glucose and 1% Fructose for some varieties. I didn’t read the paper, not positive what the numbers represent.

Glucose (%) 0.93 ± 0.40 0.85 ± 0.28a 1.00 ± 0.40ab 1.16 ± 0.49b 0.91 ± 0.51a 0.86 ± 0.37a 0.037
(0.2–2.1) (0.2–1.7) (0.2–1.7) (0.3–1.9) (0.3–2.1) (0.2–1.7)
Fructose (%) 1.02 ± 0.41 0.96 ± 0.28a 1.04 ± 0.41a 1.24 ± 0.54b 0.97 ± 0.47a 0.98 ± 0.40a 0.109
(0.2–2.2) (0.4–1.7) (0.3–1.9) (0.3–2.2) (0.2–2.0) (0.3–1.8)

Well, it was apparently written as an irony.

Well, they don’t mean a thing to me!

I don’t think lemons are irony, either. Or any other sort of metallic taste.
