Who writes here — and why it matters to you

My name is Marcos Aurélio Veras da Fonseca. I am a Chemistry teacher with over 20 years of classroom experience, an Informatics educator with over 30 years in the field, a proud grandfather of four, and the creator of Saúde com Equilíbrio — a Brazilian health and wellness blog focused on those aged 60 and above.

Anúncio

When you read an article here, you are not reading an anonymous AI or a generalist writer with no scientific background. You are reading someone who has spent decades teaching how matter works at the molecular level — and who now applies that same scientific rigor to translate health research into clear, accessible language for people who deserve honest, evidence-based information.

My background and qualifications

  • Chemistry teacher — 20+ years of classroom experience, with a deep foundation in biochemistry, nutrition science, and how the body works at a molecular level
  • Informatics educator — 30+ years working with technology, from the early days of personal computing to the current AI era
  • Digital content creator — since January 2024, with over 225 published articles on health, longevity, and well-being
  • Grandfather of four — which gave me a personal and deeply human perspective on aging, caregiving, and what quality of life really means after 60

My background in Chemistry is not incidental. It means that when I write about nutrition, supplementation, or how the body responds to aging, I read the original studies — not summaries of summaries. I understand mechanisms of action, biochemical interactions, and the gap between what science actually demonstrates and what marketing exaggerates.

Why I created this blog

I watched people close to me reach their 60s confused and overwhelmed by contradictory health information. Miracle teas. Fad diets. Supplements with no scientific backing. And on the other end, a medical language so technical it pushed people away rather than helping them.

Saúde com Equilíbrio was created in January 2024 to fill that gap: evidence-based health content, written by someone with a scientific foundation, for people who deserve clarity.

I published consistently for over 11 months before any monetization. Not because I had no options — but because building trust always comes before anything else.

How I research and validate content

Every article published here follows a clear methodology:

  1. Primary sources first — I consult PubMed studies, WHO guidelines, Brazilian Ministry of Health publications, and recommendations from medical societies such as CFM and SBD before any secondary source
  2. Evidence grading — I distinguish between established scientific consensus, promising but inconclusive findings, and popular claims with no scientific basis
  3. Teacher’s review — every article goes through the same lens I use in the classroom: “Is this accurate? Is this accessible? Is this useful?”
  4. Regular updates — health articles become outdated. I revisit and update key content regularly, with visible update dates on every article

Important: All content on this blog is strictly informational and educational. No article substitutes for consultation with a doctor, nutritionist, or other qualified health professional. I always encourage readers to seek personalized professional guidance for health decisions.

Editorial transparency

  • Use of AI tools: I use artificial intelligence tools to support research organization and content drafting. All published content is reviewed, validated, and rewritten by me based on primary sources consulted. Editorial responsibility is always mine.
  • Links and recommendations: when I recommend products or services, I disclose any commercial relationship. The majority of content is independent and not sponsored.
  • Corrections: found something inaccurate? Please tell me. I correct transparently and update the article.
