Answer: Diet
Explanation: Different forms and ways of dieting can drastically reduce the symptoms of the disease. Proper nutrition reduces the risk of many diseases and, most importantly, cleanses the body of harmful substances and free radicals. These harmful substances and free radicals are precisely the causative agents of many diseases. Eliminating them with the help of a diet increases the body's immunity and its ability to cope with the disease. In support of this thesis is the fact that the so-called natural medicine is more and more prevalent in treatment, where no drugs or pharmacology are consumed, but only healthy foods and diets.
