Answer:

Detoxification, or detox, is the process of removing toxins from the body. In medicine, this term applies only to individuals undergoing treatment for poisoning from drugs, alcohol, or heavy metals, always under medical supervision. The human body possesses a complete natural detoxification system, including the liver, kidneys, lungs, skin, and intestines. These organs work 24/7 to eliminate harmful substances. Therefore, a healthy body does not require additional detoxification.

Applying detox methods such as complete fasting, consuming only lemon water or juice for many days, or using enemas can lead to dehydration and damage to the liver and kidneys. Excessive nutrient absorption from vegetable and fruit juices can also cause insulin resistance, increasing the risk of diabetes and obesity.

Regular, prolonged detox using only juice while completely avoiding other foods can lead to significant deficiencies in essential micronutrients. For individuals with underlying health conditions, these practices may worsen their illnesses. For example, consuming too much fruit and glucose during a detox can increase uric acid production in gout patients. Similarly, people with high blood pressure who restrict their diet may lack magnesium, increasing their risk of cardiovascular disease.

Raw vegetables and fruits used for detox may contain parasites if not properly prepared. Furthermore, heavy metal poisoning can occur from using unknown herbs or detox products. When the body is starved for too long during a detox, the liver increases fat breakdown for energy, leading to an excessive accumulation of ketone bodies.

Improper interventions in the digestive tract, such as using enemas with lemon, salt, coffee, or unknown solutions, can disrupt bowel movements and cause hemorrhaging.

Currently, there is no scientific evidence supporting detox diets for toxin elimination. To effectively support the liver, kidneys, and intestines, you can implement scientifically sound detoxification methods, such as drinking 1,5-2 liters of water daily and maintaining a healthy lifestyle. Your diet should be balanced, providing adequate energy, protein, unsaturated fats, and essential vitamins and minerals.

You should consume plenty of green vegetables, fresh fruits, and whole grains to provide fiber and antioxidants (vitamin C, E, carotenoids, polyphenols) that protect cells from free radicals. Turmeric, garlic, green tea, artichoke, broccoli, and carrots also support liver function. When adequately nourished, the body's immune system strengthens, enhancing its ability to combat environmental aggressors.

You should limit alcohol, smoking, and processed foods. Regular exercise, stress relief, and sufficient sleep boost blood circulation and support metabolism. If you are considering detox for weight loss or beauty purposes, monitor your body closely and stop immediately if you experience fatigue, blurred vision, dizziness, or nausea.
