how much whole wheat bread in a daily diet

Bread is fine for hens, but whole wheat is much better.

Learn to read the label. At one time "100% whole wheat bread" meant you were eating whole wheat and nothing much else. After whole wheat bread became very desirable, the new labels on average bread read "made with 100% whole wheat bread".

My rule for bread is only one line of ingredients (when I am strict, only three ingredients: water, flour, yeast).

It depends on the type of bread.
There is 0.293 grams of sugar per 100g of wheat. However that is just the minimum from the wheat itself; some recipes add additional sugars to the bread so be sure to check the nutritional panel. It is not uncommon to find additional syrups and sugars added for flavoring.
It has to do with the way your body breaks down sugars. White bread has simple sugars, which are empty calories. Wheat bread has more complex sugars, and provide more energy. Also, wheat bread has more fiber.
