Cleansing programs: Friend or foe?— published: 04-01-2014
A hot trend in nutrition and dieting for some Warfighters is internal cleansing (or “cleansing” for short). Typical cleansing programs promise renewed energy, weight loss, and a fresh start—appealing offers following the rigors of a deployment, a recent change of duty station, or just life in general. Variants of cleansing programs may include “detox” (short for detoxification) diets, dietary supplement products, enemas, or some combination of these.
Although some detox diets emphasize eating lots of fruits and vegetables and drinking plenty of water, many detox diets lack certain vitamins, minerals, and other nutrients, and are dangerously low in calories. It might be difficult for a Warfighter to obtain adequate calories for optimal performance while following a typical detox diet.
Detox supplement products often contain herbs and other plant-based chemicals that have a laxative effect. Long-term use of laxative products can cause changes in the structure of your large intestine (colon) that might have serious health effects. Laxatives can cause dehydration, which impairs performance. In addition, according to the Food and Drug Administration there are concerns about dietary supplement products containing hidden active ingredients that can result in harmful effects.
Detox enemas, often marketed as “colon cleanse” products, cause the contents of the colon to be quickly expelled. Detox enemas contain a variety of substances, some of which can cause allergic reactions or electrolyte imbalances. Since many detox enemas are self-administered, there’s also the risk of tearing the inside of your rectum during the procedure, which can cause septicemia—a type of bacterial infection in the blood.
The guiding principle behind cleanse programs is that environmental and dietary toxins supposedly build up in your body, and you need to get rid of them to be healthy. However, there really isn’t any scientific evidence backing up these claims. Your body is designed to detox itself by getting rid of wastes through urine, feces, and sweat. The best way to take advantage of these built-in detox systems is to drink plenty of water (to produce more urine), get plenty of fiber from fruits, vegetables, and whole grains (to help pass feces), and exercise (to produce sweat)—a proven program to help you perform better and live a healthy life.
