For legumes in general, it is always more advantageous to prefer grains without husks (if, of course, possible). Sprouted mung beans offer the possibility to easily remove the husk; at least for children, try to eliminate these concentrated sources of fiber and phytates as they are an undue burden on the digestive tract.
In this age, it is important to monitor the following factors in relation to proteins:
1. Origin.
The ratio between plant-based and animal-based proteins is generally addressed as approximately 30:70, which is presented as metabolically advantageous. However, take these values with a grain of salt and mostly as a general guideline, as they aim to ensure a sufficient supply of essential amino acids, which are more readily available from animal foods. If you succeed in processing legumes in such a way that significantly reduces antinutritional components, their daily consumption in moderate amounts is acceptable.
2. Quantity and distribution throughout the day.
Here, it is necessary to do a little counting, not in the sense of tracking every gram, but rather by monitoring their sources on the daily plate. Generally, each main meal should include a substantial source of protein. It is therefore up to each parent to ensure this for the child in the form of eggs, dairy products, meat/fish, or easily digestible legumes. If legumes are consumed once a day, the approach is reversed - meaning legumes serve as a supplement to animal sources.
The greatest reduction of antinutritional factors can be achieved through thorough cooking, preferably in a pressure cooker—the combination of high temperature and pressure is capable of breaking down the structure of these undesirable components. However, it is beneficial to soak the legumes for a longer period beforehand or even to sprout them, both methods result in the reduction of antinutritional substances.
Legumes have a relatively high absorption capacity, meaning they can absorb a larger amount of salt during cooking, which increases the sodium content in the diet and subsequently the load on the kidneys and cardiovascular system. For this reason, it is recommended to add salt only after the preparation is complete, and the overall amount of salt used will be significantly lower in relation to the flavor effect.
When it comes to the content of anti-nutritional substances, some sprouted legumes can indeed be consumed without cooking (peas, chickpeas, mung beans, lentils...), as the sprouting process significantly reduces the levels of these undesirable components. However, it is still important to note that the hull, which remains part of the sprouted grain, is still a concentrated source (primarily of phytates) – therefore, it is beneficial to seek methods to remove it from the food.
At the same time, remember that the sprouting process occurs in moisture, and microbial activity is part of the whole process. Fresh sprouts are therefore quite an ample source of not always desirable bacteria and especially molds.
For these reasons, it is often worth cooking them, as the overall impact on the nutritional profile of the food will not be as detrimental as the microbial risk.
The term "vegan collagen" is largely commercially derived and targets products that aim to support collagen production in the body through their composition, as collagen is purely an animal protein. The foundation of their composition includes substances necessary for collagen production—amino acids (proline, lysine, and their derivatives), vitamin C, and certain minerals. In this respect, there is no reason to believe they would be less effective than products with animal sources.
The ratios of legumes to grains should always be addressed in relation to the planned dietary concept. Treat legumes as a significant source of protein, meaning their proportion in the diet should be based on the amount of protein you need to ensure in your diet (along with dairy products and eggs). In such cases, the ratio of legumes to grains becomes a secondary indicator.
There are numerous types, primarily those that promote the production of digestive enzymes and juices, thereby making the entire digestion process more efficient. The most significant include cumin, coriander, lovage, pepper, fennel, ginger, and blends like curry.
By making adjustments to our diet, we have the opportunity to manipulate metabolic behavior, and this applies to the number of meals throughout the day. For example, if an individual's metabolism is too slow, it can be beneficial to support it by increasing the number of meals per day, including reducing the fat content and adjusting the ratio of Ca:Mg and Ca:P. These options are simply available to us, and it is up to us whether we utilize them.
Address the complexity of proteins primarily in specific situations that require it. Typical examples include vegan diets or elite athletes, where the demands for the quantity and quality of protein increase significantly compared to the average population. This does not mean that every protein-containing meal must necessarily exhibit amino acid completeness; the goal is simply increased attention and effort directed in this direction. Every diet plan should be, above all, practically feasible, and your considerations when translating theory into practice should always be based on this.
From the perspective of nutrient bioavailability, bone broth is the most advantageous, as it contains the highest concentration of substances (proteins and minerals). However, it is also beneficial to consider a broader context; using plant sources in broths can also provide sources of fiber, which is both an important factor and advantage. The condition (particularly for legumes) is their thorough cooking, ideally in a pressure cooker, which leads to the breakdown of antinutritional components, the release of minerals from their bonds, and the enrichment of the broth with fiber fractions.
The rules of LC (low carbohydrate) are not precisely and strictly defined. The foundation is limiting the intake of carbohydrates, where their richest sources (excluding technologically processed foods) are cereal grains and products made from them, as well as selected types of fruits and some legumes. In this context, it is not an issue to include legumes, but of course in moderate amounts. They are a rich source of proteins, fiber, minerals, and in some cases, fats, while their carbohydrate content is relatively low, making them suitable for the concept of a low carbohydrate approach.

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.
