Take this rule with a grain of salt; in reality, this ratio simply aims to guide us to have more vegetables than fruits on our plates throughout the day. You practice this in exercises with the support of algorithms in the educational app, where each representative is evaluated. In fact, the definition of a "portion" also includes the weight factor, which you are not required to track in the exercises. Therefore, focus on ensuring that this ratio is respected on a long-term average; an excess of fruit would disproportionately increase the sugar content in the diet.
Once you reduce the amount of animal products in your diet, the volume of plant-based foods will automatically increase. If, in such a situation, the foundation of the diet consists of minimally processed ingredients that contain a significantly higher fiber content, it is natural for the amount of fiber in the diet to rise as well. The digestive tract will always react to an excess of fiber in its own way, and this cannot be avoided. It is necessary to adjust the diet in such a way that you also monitor the fiber content in the daily regimen, and if the reaction of the digestive tract indicates that you have exceeded the limit, it is wise to reduce fiber intake and simultaneously thoroughly cook its sources to reduce the digestive burden. The complexity of this process increases towards veganism, meaning you will have to select foods that form the core of your diet even more carefully.
Although there are studies comparing the nutritional value of conventionally grown and organic fruits and vegetables, their results are not conclusive (they vary depending on the type of fruit or vegetable, soil, climatic conditions, and other factors). Generally, it can be said that organic fruits and vegetables have been shown to contain higher amounts of antioxidants, vitamins, and minerals than conventionally grown crops.
Current recommendations from the WHO regarding sugar intake aim for a maximum of 90 g per day, with 50 g being added sugars, and there is consideration to reduce this amount to 25 g. When assessing the quality of nutrition, it is important to distinguish between naturally occurring sugars in foods and those added during processing. The fact is that fruits and fruit products (juices, compotes, jams, etc.) are the richest sources of naturally occurring sugars, so it is advisable to monitor the proportion of this food group in the diet. The same applies to the category of foods with added sugars, where there is a significantly higher risk of excess. This is one of the many meaningful examples and essentially a reason why it pays to monitor the nutritional quality of food, as numbers can sometimes speak clearly.
25 g of added sugars per day may initially seem like a low limit, but when converted, this amounts to 6 sugar cubes, which, when visualized in this way, takes on a different dimension than an abstract value. You are correct in stating that reaching this limit is not easy, especially in the long term. On the other hand, it is necessary to realize that this is a dietary component that we actually do not need and that does not benefit our health. This topic should lead to reflection on how strictly we will monitor the proportion of natural and industrially processed foods in our diet.

Mgr. Martin Jelinek
Lecturer and author of the educational system
Nutrition educator, lecturer, and author of the educational system and the ZOF learning application.
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.
