Thats called net carbs. Lots of companies would write the net carbs on their protein bar or any other health consious product. I would count carbs and fiber seperately, not make a net carb list. So to answer your question count your carbs as 34 grams because fiber does not add on calories, but make sure to count fiber seperately also aiming for 25 grams.
Here is an article
"studies demonstrated that a high-carbohydrate/high-fiber diet significantly improves blood glucose control and reduces plasma cholesterol levels in diabetic patients compared with a low-carbohydrate/low-fiber diet. In addition, a high-carbohydrate/high-fiber diet does not increase plasma insulin and triglyceride concentrations, despite the higher consumption of carbohydrates. Unfortunately, dietary fiber represents a heterogenous category, and there is still much to understand as to which foods should be preferred to maximize the metabolic effects of fiber. There are indications that only water-soluble fiber is active on plasma glucose and lipoprotein metabolism in humans. Therefore, in practice, the consumption of legumes, vegetables, and fruits--rich in water-soluble fiber--should be particularly encouraged. The mechanisms by which dietary fiber exerts its hypoglycemic and hypolipidemic activities are unknown. However, the ability of dietary fiber to retard food digestion and nutrient absorption certainly has an important influence on lipid and carbohydrate metabolism. The beneficial effects of high-fiber foods are also exerted by some foods not particularly rich in fiber. The fiber content and physical form of the food can influence the accessibility of nutrients by digestive enzymes, thus delaying digestion and absorption. The identification of these foods with a low-glycemic response would help enlarge the list of foods particularly suitable for diabetic patients. In conclusion, a diet low in cholesterol and saturated fat should be recommended to all diabetic patients to prevent cardiovascular disease. A balanced increase in consumption of fiber-rich foods and unsaturated fat is the most rational way to replace foods rich in saturated fat and cholesterol in the diabetic diet."
The fiber found in whole grain breads and cereals has insoluble fiber. This type of fiber draws water into your intestines and helps maintain regularity. As food travels through your gut more quickly and is more diluted with water, the exposure of your gut wall to potential carcinogens is decreased.
The soluble fiber in oats, legumes, fruits and vegetables binds up bile acids and disposes of them. As stated previously, the body likes to recycle bile and use it over and over again. These fibers form a gel substance in the gut that prevents this recycling process. More cholesterol is used to create more bile and this helps increase cholesterol utilization which lowers serum cholesterol.
