Today I obtained the answer: 21.3g of sugar for every 100g (or was it ml?). So that means that a 700ml bottle has 150g of cane sugar, i.e. 35.5 teaspoons of sugar (4.2g). Ouch! Not so healthy after all, even though there are no preservatives. Still, it's better than "ketchup" which has all kinds of other nasties.
They have a version with artificial sweetener instead, but I think the health risks of that concoction must be pretty toxic. One has to ask why they need to put so much sugar in the product. To counteract the taste of the vinegar? The mind boggles. I mean, there's a teaspoon of sugar for every tomato in the bottle! I guess they had to "work hard to cram them all in".
Update: According to the label (which uses a very small font) there are 27g of carbs per 100g serving. That means that in a bottle there are 40g of carbs not comprising cane sugar. Divide that by 36, and you get some very small tomatoes, unlike the giant ones shown in the TV ad below. According to Answers.com: "One medium, whole, red, ripe, raw tomato, 2 3/5 inches in diameter and weighing 123 grams contains 5 grams of carbohydrates, on a year-round average." That means there would be 8 tomatoes in a bottle of tomato sauce, not 36. Since they actually use "reconstituted tomato paste", the ad agency claims about tomatoes have been all lies from the beginning, whichever way you look at it. I don't understand why food companies think it is OK to mislead the public like this.
