It is that time of the year again. With our digestive system trying to recover from the trinity of festive indulgence, some may find themselves resolved to embark on a healthier lifestyle, and they hope to achieve it quickly. Enter cleansing, or detoxification.\r\n
What is cleansing?
\r\nCleansing regimens are widely publicised in the media. They are promoted to “cleanse” specific organs (bowel, liver, kidney etc.) or“detox” the body from toxins inhaled from the air or 300-207 TE0-141 ingested from food. The typical motivations for cleansing include recovery from the over-consumption of alcohol or generally to improve health. Sometimes, the first step in a weight management programme would include cleansing.\r\n\r\n
\r\n\r\nThere are different methods of cleansing, a term that also refers to ‘detoxification’. The regimen may incorporate buy Windows 7 Ultimate SP1 a preparation that is herbal, or medicinal with a laxative effect. Instructions to ingest copious amounts of water, juice or fibre are also common. Alternatively, individuals might approach cleansing by fasting, or strictly eliminating whole food groups from their diet.\r\n\r\nWhile the advantages of cleansing seem substantial and promising, it may bring more harm than benefits.\r\n
The evidence behind cleansing is lacking
\r\nCleansing follows a theory called ‘auto-intoxication’. It suggests that non-specific toxins and residual faeces collects in our intestines which in turn poisons our body, including the liver.\r\n\r\nHowever, physiological evidence has shown that our lungs, liver and bowels can naturally eliminate waste, thus rendering methods of bowel cleansing unnecessary. Also, it has not been proven that faecal matter comprises of toxins. Additionally, the removal of excess mucus from the colon is not widely supported. Constipation is indeed a common problem today manifesting in symptoms like headaches, mental 300-207 sluggishness or feeling “rotten”. However, that is often due to low dietary fibre intake, inadequate fluid or physical activity, instead of toxin accumulation in the body.\r\n\r\nThe claims about certain foods or herbal ingredients having the ability to detoxify our system or reduce inflammation have also not been scientifically tested. The available studies show inconsistent results, and the positive effects promoted are predominantly based on anecdotal reports.\r\n\r\n
The health claims are unsubstantiated
\r\nIn many cases, cleansing and detoxification claims are false. Cleansing can pose a health risk to a healthy individual such as bowel perforation and dehydration. The risk would grow greater if you have:\r\n
- Kidney, liver or heart disease
- An eating disorder
- Are pregnant or breastfeeding
- Other medications, whether prescription or over-the-counter
\r\nWhile herbal products are perceived to be more natural than their synthetic counterparts, they are associated with toxicity in the kidneys. The toxicity may be due to the direct intake of herbal products, contamination of the herbal preparation or simply its interaction with other medications that an individual is taking. In a study where 21% (219 out of 1,044 women) from a clinic were taking herbal products, a proportion experienced side effects that were of cardiovascular and gastrointestinal nature.\r\n\r\nThere are some cleansing procedures that carry a risk of immediate, adverse outcome. For example, bowel perforation is the most commonly reported event in colonic irrigation. Others methods, however, may not result in such apparent negative symptoms. One example is the practice of juicing fruits and vegetables. This method has been promoted to cleanse the liver, as well as other organs.\r\n\r\nIt is based on preliminary evidence that several vegetables, fruit, and herbs could reduce or enhance certain specific enzymes that function to detoxify and metabolise drugs. Among the vegetables, fruits, and herbs studied are cabbage, broccoli, asparagus, grapefruit, cranberry, and parsley.\r\n\r\nIn these early-stage studies, the fruits and vegetables were juiced to ensure consumption by rodents. For humans, research has shown that the changes in enzyme function could be similarly achieved through the consumption of whole fruits and vegetables, along with a balanced diet that included grains, dairy, and protein foods.\r\n\r\nHowever, some juicing plans instruct strict, exclusive adherence to the beverages. Such a diet is detrimental to children, who could be put at risk of diarrhoea, tooth decay and abdominal distension. Additionally, with their nutritional needs stymied by juice which is low in protein, a nutrient essential for muscle development, nutritional deficiencies could be expected. The same outcome could also affect adults.\r\n\r\nIn juicing plans that do not limit or eliminate food groups from the diet, large quantities of juice can contribute to excess energy intake, and thus, lead to obesity in adults and adolescents. Those taking medications for their heart, cancer, organ transplant or infection should be wary, because juice has been found to alter the metabolism and/or absorption of 85 different drugs.\r\n\r\n
\r\n\r\nLastly, for those hoping to lose weight by taking preparations with a laxative effect, the resulting effect of diarrhea would not just bring about calorie excretion in the stools, but also a large water loss of 3-6 litres. While the fluid loss would reduce an individual’s weight, the electrolyte imbalance and dehydration could lead to life-threatening consequences.\r\n
What now, if they don’t work?
\r\nA healthy lifestyle is not something that can be achieved overnight. It would be unreasonable to use a quick-fix approach to change your eating habits and way of life that has been cultivated TE0-141 for years.\r\n\r\nThe habits to incorporate into a healthy lifestyle are not new. For nutrition tips, see the 13 eating habits that make a healthy lifestyle easily achievable. However, the challenge in achieving a healthy lifestyle has ever been in the long-term compliance, not in the undertaking.

Achieving a healthy lifestyle is after all, a long-term resolution.\r\n\r\nNote: This article does not review the information regarding medical procedures that require bowel cleansing.\r\n\r\nAbout the writer:\r\n\r\nSoo Lay is an Accredited Practicing Dietitian (Australia).
