Abstract: Studies demonstrate that the use of nutritional supplements containing beta-glucans stimulates the immune system, modulates inflammatory activity, and promotes so-called immune training. Beta-glucans are prebiotics that stimulate the growth and activity of gastrointestinal microbiota and inhibit pathogen growth. Nutritional intervention is crucial for patients' positive evolution, and providing a supplement with highly bioavailable nutrients can make a difference in their nutritional, metabolic, and immune status. Therefore, the study aims to verify the effectiveness of the innate and adaptive immune response to a nutritionally balanced fermented food, containing oral or enteral beta-glucans, in patients treated at 3 Emergency Care Units in São José do Rio Preto, São Paulo, Brazil. This is a prospective randomized study with a characteristic design involving patients treated in the medical wards of 3 Emergency Care Unit. The following assessments will be conducted: Global Subjective Assessment for adults and Mini Nutritional Assessment for the elderly, Sociodemographic, and Laboratory Evaluation.

Inclusion Criteria:

Patients admitted to the medical clinic ward
