Study to Evaluate the Organoleptic Perception of Oral Nutritional Supplements for Oncological Patients

Nutritional therapy is key to helping cancer patients get the nutrients they need to maintain body weight, strength, tissue and organ integrity, and face likely infections. Some cancer treatments work best when the patient is well nourished and has enough calories and macronutrients from food. According to the latest consensus, the first step in nutritional intervention is nutritional recommendations or dietary advice. These recommendations must be realized if the patient is capable of ingesting at least 75% of the nutritional requirements that correspond to them and, if there is no approach to an upcoming risk therapy. As long as the oral route is not damaged, in dietary advice this should always be the first option. Increasingly, laboratories specialized in nutritional products prepare and improve the composition of supplements. They are complete, specific and perfect to meet the dietary needs of patients who require it. But, to fulfill their function, they have to be ingested by people and for that they have to have good organoleptic characteristics, a very important nuance that is sometimes not taken into account in the manufacture of these products. It is the object of Adventia Pharma, S.L. develop new Oral Nutritional Supplements specific for cancer patients and that meet optimal organoleptic characteristics. For this reason, a pilot study will be carried out that will evaluate different sensory and organoleptic aspects of the prototypes of supplements developed by the company to determine the consumer's reaction to the products developed and subsequently be able to select the one with the greatest acceptance.

In cancer patients there is great difficulty in maintaining and/or improving their nutritional status if early nutritional support or surveillance measures are not taken, which can prevent progressive deterioration. The act of eating in a traditional way influences the perception of normality or illness in patients. Nutrition not only represents an essential parameter in the development of cancer, but it can also be a fundamental factor in its treatment. In the case of cancer, both the disease and the treatment have a direct impact on nutrition and generate bodily changes that gradually appear as a consequence of them. Cancer produces a direct decrease in intake, due to the disease, the metabolic alteration induced by the tumor, the physiological changes produced, the effects of cancer treatment and the presence of symptoms (depression, anorexia, vomiting, diarrhoea, pain , etc.); mechanically interfering with the normal transit of the digestive tube, or indirectly through the secretion of substances that act on peripheral receptors or on the hypothalamus. The patient may therefore be faced with a tumor cachexia syndrome characterized by weight loss, reduced fat and muscle mass, anorexia with reduced intake, early satiety, hypoalbuminemia, anemia, and progressive weakness, among others. others. This malnutrition aggravates the problem of immunosuppression that the patient already has due to his cancer, and has a great impact on functional capacity, with an increase in complications, the rate of infections, decreases tolerance to cancer treatment, the patient's quality of life and thus their chances of survival.

Oral nutritional support consists of the administration of nutrients and other necessary adjuvant therapeutic substances, with the purpose of improving or maintaining the nutritional status of a patient. This support is indicated for patients who are in different clinical situations such as limitation of intake, swallowing, transit, digestion, absorption and/or metabolism of nutrients, or who have special energy and/or nutrient requirements that cannot be covered with natural food.

Therefore, the main objectives of nutritional supplementation in cancer patients are the following:

* Prevent or correct nutritional deficiencies.
* Minimize the side effects of anti-neoplastic treatment.
* Improve tolerance to anti-neoplastic treatment.
* Improve Life Quality.
* Help achieve optimal body weight.
* Educate the patient/family about special nutritional needs. In conclusion, the choice of a nutritional supplement if it is indicated for a specific nutritional treatment should be based on its composition, its physical characteristics (taste, smell, texture...) and the underlying disease. It should also be adjusted as far as possible to the patient's tastes. There are different types of formulas, some designed with specific nutrients for certain diseases, disorders or conditions (oncology, pressure ulcers, constipation, diarrhea, etc.) and others that are intended for patients without specific needs.

Increasingly, laboratories specialized in nutritional products prepare and improve the composition of supplements. They are complete, specific and perfect to meet the dietary needs of patients who require it. But, to fulfill their function, they have to be ingested by people and for that they have to have good organoleptic characteristics, a very important nuance that is sometimes not taken into account in the manufacture of these products.

For this reason, a randomized, cross-sectional and double-blind pilot study was performed to evaluate different organoleptic properties of 5 oral nutritional prototype of supplements. The investigators included 30 patients. Each volunteer tasted the 5 different prototypes the same day in a different order.
