Starch is generally interpreted to mean carbohydrates. Since your body doesn't absorb fiber as readily, some people subtract the grams of fiber from the carbohydrates, giving a net grams carbohydrate figure. By law, all processed foods sold in the US have to give grams of carbohydrates and fiber on the label, along with other nutritional information. If you're eating unprocessed foods like fruit and fresh veggies (good for you), you can purchase a paperback book at any bookstore that will give you the figures - it's called a carbohydrate counter.

You can't exactly measure the starch of something at home, but if you get some potassium iodide liquid, you can put a drop on the food and watch the color change. The darker (purple) the color, the more starch. The lighter the color, the less starch.
