Cleansing is often promoted to improve health by ‘cleansing’ the bowel and removing toxins from the body. It has been claimed that it can boost energy and immunity, promote healthy intestinal bacteria and start weight loss. The truth is, there is no scientific evidence to show that cleansing maintains or improves bowel health, prevents colon cancer or achieves lasting weight loss. Your intestine, lungs, liver and kidneys already effectively remove waste from your body every day. These diets can be harmful and cause unpleasant side effects such as cramping, nausea, vomiting, headaches, lack of energy; or more serious side effects, such as dehydration, low/high blood pressure, vitamin and mineral deficiencies, and many more. Instead look for effective and trusted ways to improve your health, boost your energy and maybe lose some pounds along the way by seeking professional help from a registered dietitian.
