The article from El País highlights the overwhelming abundance of nutritional information available in social media and other media but points to a troubling lack of consensus among experts on what constitutes healthy eating. It emphasizes that even among qualified professionals, dietary recommendations can vary dramatically, indicating deep confusion in the realm of nutrition. This situation is evidenced by conflicting messages and a chaotic environment for people seeking guidance on healthy eating.

The piece goes on to describe how the necessity to instruct humans on how to eat underscores a distinct problem, suggesting that unlike other animals, humans struggle to intuitively understand their nutritional needs. The author critiques the state of dietary advice as resembling a chaotic 'dietetic nonsense', describing how even academic professionals with advanced degrees cannot agree on simple truths about nutrition. For the average person, this makes navigating healthy eating particularly challenging.

The article concludes by asserting the importance of simplifying the guidance people receive. Instead of focusing on calories, proteins, or strict diets, it suggests adopting straightforward and science-backed principles for healthy eating that can be easily implemented without excessive complicating factors. The goal is to encourage easier and healthier eating habits that are effective and sustainable without the stress often associated with dieting.
