Plain English Summary
Background and study aims
The immune system is a system of biological structures and processes that are in charge of protecting the human body from various harmful agents that can damage it. It protects the body from things that could make us ill or cause death, such as bacteria and viruses. The immune system takes time to mature, which means that children under five years of age are more susceptible to infections such as diarrhea and the common cold. One way to help children’s immune systems fight off common infections is to give them food supplements that have extra ingredients designed to strengthen the immune system. A common ingredient used to boost food supplements is called beta-glucan. Beta-glucans come from plants and fungi (mushrooms), and they are well known to help support the immune system. The aim of this study is to see whether a food supplement containing beta-glucans derived from the mushroom Ganoderma lucidum can help boost the immune system of children aged 3 to 5 years old.
Who can participate?
Children attached to the Childcare Foundation - Medellin (Fundación de Atención a la Niñez (FAN) – Medellin)
What does the study involve?
Participants are given a nutritional supplement with added beta-glucan to take 5 days a week for 6 weeks. Blood tests are carried out at the start of the study, then again after 6 weeks, to see if the participants’ immune system is stronger after taking the supplement.
What are the possible benefits and risks of participating?
The results of this study could lead to beta-glucan-enriched foods being used to improve the health of preschool children.
Where is the study run from?
