How it works?
How to use Nutri?

This page aims to show one of many possible and real scenarios of using the Nutri Nutrients and Vitamins. Of course, everyone will find their own way to use the program, but this one shows the possibilities of the App in a cross-sectional way.

Let's imagine that we live in a region where autumn has just arrived. This is mostly the time of increased infections. One of the ways to improve the body's immune system is to naturally support it with the right nutrients. Using the example of the Nutri Nutrients and Vitamins app, I want to show how to quickly check and choose the right food products conducive to improve immune system.

Case Study: News

First of all, the program allows you to check what nutritional values mainly build our immune system.

To find out which of the micronutrients have the greatest impact on it, select the "Nutrient impact" option from the main menu.


We are given a view with the option of selecting a micronutrient and displaying the associated positive effect on the body, or selecting the type of positive effect and displaying a list of associated nutrients. 

Let's choose "immune system" from the list.


As you can see, many of the basic nutrients influence the immune system.

So how to check and search for products that contain all of the listed micronutrients (in addition, in the greatest amount)? 


In the displayed view it is possible to easily create a list of products containing the most of a single nutrient. Just tap on the selected item. Let it be, for example, vitamin C. We get a view similar to the one shown in the ne figure. 


For a while, however, we can create a more complex query and create a product list based on up to 3 search criteria. To create a list of products that best meet the 3 search criteria, select the "Query filter" option from the main menu. From the previous list of elements building our immune system, let’s choose 3. For example: Vitamin C, Beta Carotene and Iron. We will list the maximum content of these items. So, we mark the "max" option everywhere (as in the figure).


As a result of the search, we get a list of products that meet the best search criteria.

The figure shows the direct search result. The scrollable list can of course be extended by clicking the "find more" button at its end.


Now we can tap on the selected food item to find out more about it. 

Probably not all products on the list suit us. This is not what we're really looking for. Fortunately, the list of results can be narrowed down very quickly and easily.

Just tap on any product from a specific product group (groups are visible in the list). You will go to the next view that allows you to reject a given product group or limit the main list to a single group of food products. An example of filtering is shown in the figure.


In the scenario we removed by this way the following product groups (from original list):

-baby foods,

- beverages,

- sweets, 

- snacks.

The view of the modified list is shown in the figure.


After reflection, we decided that we would like to limit the list only to products from the "vegetables and vegetable products" group.

So, we need to tap again on any product belonging to this group and choose the "Leave only this group" option.

The filtering result is shown in the figure.


While browsing the resulting list, we found some interesting product. Namely sweet yellow pepper - raw one.

To find out more about it, click on this product (as we did before). And from the next view, select the "Product details" option. 

Nutrition facts will appear in the next view.


When assessing the content of individual micronutrients, it is worth determining the weight of the product. If we do not know it, we can use typical substitutes. If such a substitute has been defined for a given product, it is possible to tap it - green button above the list of nutrients facts. You can also determine the weight yourself. We use the plus and minus buttons for this.

Tip: By taping the product weight numeric value, the value will be set to 100. 

There is also a third option to evaluate the amount (weight) of a product by using nutritional conversion factors. The program includes a carbohydrate exchanger (and the so-called carbohydrate portion) as well as serving substitutes. You can read more about these indicators in the "details" tab (check site menu). This is especially important, for example, for diabetics.

Relating figure shows a view of the listed exchangers for our sample typical serving of raw yellow pepper.


In the case of our product, we see that a typical piece is about 186 grams. This equates to about 2.4 servings of vegetables. Converting it to the carbohydrate index we get the value of 0.8. Scrolling through the list of nutritional values, we'll find out that our sample pepper does contain a lot of Vitamin C. There is some Iron and Beta Carotene (approx. 5% of the average daily requirement) too. Moreover, there is also a bit of Folate, Selenium and a lot of Vitamin A. In fact these are microelements that significantly affect building of the body's immunity (according to the previous list).

It was easy, wasn't it? By clicking on a few buttons very quickly and easily, we got information that was not so obvious. In this way, we can create any query by searching for nutrients in food products of interest. 

The main topic, however, was autumn and improving body’s immune system. What if we want to search for a specific product knowing its name, group or subgroup name?

Also, no problem with that. From the main menu, simply select "Find a Product". Let's assume that we want to check whether, for example, “pickled cabbage” will be an appropriate product that can positively affect the immune system. Enter or search for elements of interest in the appropriate view fields. An example is shown in the next picture.


This way we will search for a specific product. If the name in the database is slightly different or the assignment to a group or subgroup is different than what our intuition tells us, we can get an empty result list. In order to avoid problems, it is better to generalize the query. If possible, try to select only a group of products or a single key word. For example, instead of writing "pickled cabbage", write "pickled". We will then search for all products that have the word "pickled" in the name, but we will avoid the situation described earlier.

In the case of our "pickled cabbage" we find one product in the database. Let's check it’s nutritional facts and what is the average portion corresponding to 1 cup.


Looking at the list associated with the body's immunity and our sophisticated product, we find that we have a small amount of Beta Carotene, Iron and Selenium here. There is quite a lot of Folate and Vitamin A. Protein and Vitamin C are present too.

Conclusion - "pickled cabbage" may be a good choice when it comes to building the body's overall immunity.

Tip: reviewing nutrition facts You can click on any nutrient to see the associated list of elements that the micronutrient affects (in terms of a positive effect on our health).

Individual food items can be temporarily saved in the clipboard. 


The clipboard has the basic functionality of the so-called calorie counter. The products saved in the clipboard can be summed up and obtain summary information about the content of all micronutrients.


The shown example of using the Nutri Nutrients and Vitamins app is one of many possible to come up with. The main advantage of the program is that it allows You to easily and quickly obtain complex results of searching food products in terms of the content (or lack) of specific nutrients. This is not another so-called calorie counter.

The goal of the Nutri program is to help you select the right foods. Systematic use of the application can teach proper food selection in terms of proper eating habits. However, it should be remembered that the program itself will not replace consultations with a specialist - e.g. a dietitian. 


It is worth emphasizing that the application uses a recognized database - USDA National Nutrient Database. We do not allow to add or modify the implemented database items. Thanks to this, we increase confidence in the information provided in the application.


Remember that the Nutri Nutrients and Vitamins app is available in the free version, which NOT differs functionally from the paid version. So, we encourage You to download and try the App!
