It is important because if you put in too much it will be too stiff and the starch will be overpowering.

The consistency will be greatly affected depending on how much or how little you use, and also the flavor.
Starch is carbohydrates and calories. A cup of flour is 400 calories, so 2 Tablespoons would be 50 calories . . . I think. The more flour you use to thicken something, the more calories and carbohydrates. That affects the nutrition. And generally the more flour, the more oil which also greatly affects the nutrition.
None, unless you are in a situation where you are literally starving. Starch is not a nutritional food and is not good for you unless you are not getting enough calories in your diet.
