Good day Mr. Jelínek,
I would like to ask whether there is a significant difference between commonly purchased non-organic eggs and home-produced eggs. I am specifically interested in the content of quality proteins and other beneficial substances for the body.
Thank you for your response.
The difference between them should be perceived on several levels. The protein content is more or less the same, with more significant differences primarily in:
1. The content of micronutrients (vitamins, minerals, and antioxidants) - their amount depends on the diet of the hens, where in some respects large-scale farms have the upper hand (due to feed mixtures fortified with certain substances), while in other cases free-range hens have the advantage.
2. The content of certain fatty acids - most commonly omega-3 fats, where again their content in eggs changes concerning the share of ALA in the hens' diet (sometimes it may be intentionally increased with flaxseeds).
As a result, it is not possible to universally label any method of farming as nutritionally more advantageous; it depends on the approach of a particular farmer. However, the qualitative difference is often cited in terms of the presence or absence of xenobiotics, where it is generally agreed that eggs from free-range hens are of higher quality in this regard.

Mgr. Martin Jelínek has been systematically involved in nutrition education since 1999. He is the founder of ATAC, the educational company behind NutriCourses, and the author of an educational system focused on nutrition, healthy lifestyle, and the practical application of nutrition knowledge.
He graduated from the Faculty of Science at Masaryk University in Brno. Throughout his professional career, he has combined nutrition, education, and the practical application of acquired knowledge. His educational system also includes the ZOF (Zone of Optimal Functioning) learning application, where students turn theory into practical work with meal plans.
In 2007, he launched the first intake of a six-month course focused on the education of nutrition advisors. Over time, this course became the foundation for the further development of the educational system and a range of specialised courses.
