Diets that claim to help people flush their systems are ineffective and may even be dangerous, according to WebMD. The immune system and certain organs are capable of ridding the body of toxins, regardless of what a person eats.
Frank Sacks, an MD at the Harvard School of Public Health, states that there is no scientific basis for cleansing diets ridding the body of toxins. The kidneys and liver are able to effectively remove most ingested toxins, Mayo Clinic states. The only noted benefit of following a detox diet is that people avoid eating processed foods and sugars.
Many system-flushing diets require a person to temporarily exist on juices or just fruits and vegetables. Some may also require the dieter to engage in colon cleanses, or take pills and supplements. People who do wish to detox may want to consider a clean eating plan instead. This means eating whole foods that are not processed, such as fruits, vegetables, whole grains and lean proteins. It is important to note that no detox plan is sustainable in the long term. People can experience negative side effects, which includes low blood sugar, feeling weak, nausea and headaches. In addition, following plans for a long time can result in vitamin and mineral deficiencies. People who do decide to follow a detox plan should discuss it with a doctor first.
