The discussion about the limits of traditional medicine and the urgency for a more preventive approach gained traction in one of the segments of Deusa Cast, the podcast from Portal Sechat.
In the episode, sports physician Dr. Jimmy Fardim and dentist Dr. Rafaela da Rosa analyze how medical training still prioritizes the prescription of medications, sidelining prevention, nutrition, and the impact of lifestyle on health.
The Gap in Medical Training
Dr. Rafaela da Rosa highlighted that the prevailing logic in medical schools is still reactive, focused on treating established diseases rather than building health.
“In medicine, we learn a lot about prescribing medication and very little about prevention, right? About not needing the medication,” the specialist stated.
According to her, the lack of subjects focused on nutrition and prevention limits the professional's ability to guide patients on diet, habits, and choices that help maintain the body's balance before illness occurs.
Endocannabinoid System and Lifestyle
Another central point of the debate was the role of the endocannabinoid system in regulating the body and how it can be modulated by simple daily practices. The specialist explained that non-pharmacological activities already have scientific backing in this process.
“Physical exercise, nutrition, meditation… there are already studies proving that this acts on the endocannabinoid system. When you meditate, breathe, you produce fewer free radicals, less reactive oxygen species, which generates less inflammation and less stress,” emphasized Jimmy Fardim.
Additionally, the specialist mentioned omega-3 supplementation as a complementary strategy to assist in systemic balance and reduce inflammatory processes.
Ultra-Processed Foods, Oxidative Stress, and Chronic Diseases
The conversation also addressed the negative impacts of ultra-processed foods and synthetic substances on the body. According to Dr. Rafaela, these compounds can directly interfere with cellular receptors and promote the emergence of free radicals.
“These substances either try to bind to receptors that are not made for them, damaging those receptors, or remain in the body in the form of free radicals,” she explained.
This scenario of oxidative stress, according to the specialists, is at the root of various chronic conditions observed in clinical practice, such as fibromyalgia, Alzheimer's disease, persistent pain, and sleep disorders, which manifest in different ways depending on individual predisposition.
The Challenge of Awareness
At the end of the debate, the guests reflected on the difficulty of promoting health changes in a context where medical training itself still lacks depth in these topics. For them, progress involves educating professionals and patients about self-care and environmental control.
“Most of the time, these diseases could be controlled by controlling the environment,” concluded the specialist.
