How do you minimize the bad odor of human waste?

Drink a lot of water (at least eight glasses a day), fresh juices or hot tea. This will assist in the absorption process as well as prevent constipation.
Eat yogurt or other food items that contain live microorganisms, which combat invasive bacteria, thereby decreasing the stool odor.

Make sure that you eat fruits and other foods that are rich in fiber. This cleanses the colon and helps in preventing odor.
Increase your magnesium intake, by eating nuts, seeds or green leafy vegetables.
Avoid smoking and drinking alcohol, as these practices normally alter your nutritional balance and disrupt regular bowel movements in the body.
