Foods that are considered to be good for our systems such as insoluble fibers consists of: seeds & nuts, fruit skins and root vegetable skins (such as apple and potato skins), dark leafy vegetables (such as spinach), as well as whole-wheat products. These types of foods can help you with constipation and the removal of toxic waste in your colon.

Insoluble fibers are fibers that cannot be dissolved in water, a good example of this would be the skin of a fruit or vegetable or the bran of wheat, this is why whole grain foods are considered to be a good source of fiber, because it uses all of the wheat, including the parts that are fiberous.

Insoluble fiber is more commonly known as "roughage". Basically, its the part of plants that cannot be digested and tends to push other foods through the digestive tract by absorbing water.
