giving organs( particularly the liver and kidneys) a“ break” so they can function more efficiently.
Dr Wolberg points out that one of the reasons detox diets have gained popularity over the last decade is social media hype.“ People prefer what they perceive to be quick, short-term solutions to their health issues, rather than committing to long-term lifestyle modification. They also want immediate results for their efforts.”
The problem is, it just doesn’ t work like that.“ Proper lifestyle changes need to be implemented for several years before actual health benefits are seen,” admits Dr Wolberg.
DO DETOX DIETS ACTUALLY DETOX YOUR BODY?
“ From a medical scientific perspective,” says Dr Wolberg,“ there is no evidence that detox diets actively eliminate toxins more efficiently from the body.”
She explains that various organs in the body play an important role in eliminating excess unwanted substances from the body.“ These organs include the kidneys, liver, skin and gut. In a healthy individual, these organs perform vital functions, such as regulating fluids and metabolites.”
But it’ s not all bad news. Dr Wolberg adds that there are some potential short-term benefits of a detox diet:
• Eliminating or decreasing the consumption of ultra-processed foods.“ In a recent study, the negative health implications of increased consumption of ultra-processed foods were highlighted. Individuals who had a large percentage of ultra-processed foods in their diet had lower odds of reaching the age of 70 with good brain health, physical function and living without chronic diseases.”
• Detox diets often promote increased consumption of fruit and vegetables.“ These are important components of a balanced diet. They provide vitamins, minerals, antioxidants and dietary fibre.”
• Increased water intake.
• A psychological boost.“ These diets can provide a sense of control or motivation to start a healthier lifestyle.”
Dr Wolberg is blunt:“ Detox diets do not provide long-term health benefits. To achieve optimum health benefits through diet, an individual needs to be consistent with a balanced eating plan for several years.”
WHAT ACTUALLY SUPPORTS LONG- TERM HEALTH?
There’ s growing evidence pointing towards the benefits of a largely plant-based diet.
“ A diet that emphasises fruits, vegetables, whole grains, nuts, legumes, low-fat dairy products, fish and healthy fats is one of the dietary patterns linked to healthy ageing,” recommends Dr Wolberg.
She warns that detox diets often promote the exclusion of certain food groups.“ Unless you have a properly diagnosed allergy to a food group, it should not be excluded from your diet,” notes Dr Wolberg.“ It is potentially harmful to simply cut out entire food groups, because each group provides specific essential nutrients.”
Dr Wolberg also adds that including a fasting regimen in your diet can lead to dehydration and electrolyte imbalances.“ Fasting can lead to patients feeling tired, dizzy, and having poor concentration and a lack of energy.”
“ Many of the claims made about detox diets are exaggerated, not based on scientific evidence, and the benefits are short-lived,” says Dr Wolberg.“ There is no healthier substitute for a balanced diet, regular physical activity, reduced alcohol consumption, not smoking and having enough good quality sleep!”
Dr Wolberg’ s advice – balance is key, and always talk to your healthcare provider before making any significant changes to your diet to determine what is safe and healthy for your particular needs. IB
