Summary
Lactose intolerance affects nearly half of adults, identified through clinical symptoms and blood sugar tests. This study highlights the prevalence of lactose intolerance in healthy adults, particularly among white individuals.
Area of Science:
- Nutrition Science
- Gastroenterology
Background:
- Lactose intolerance is a common condition affecting adults.
- Dietary habits and genetic factors may influence lactose digestion.
Purpose of the Study:
- To investigate the prevalence of lactose intolerance in healthy adults.
- To assess the utility of lactose tolerance tests in identifying milk intolerance.
Main Methods:
- Dietary surveys were conducted.
- Clinical data was collected.
- Lactose tolerance tests were performed on 24 healthy adults (aged 19-39).
Main Results:
- Eleven out of 24 adults (46%) showed signs of lactose intolerance.
- Symptoms included clinical manifestations and/or a low blood sugar increase post-lactose load.
- A majority of those with lactose intolerance were identified as white.
Conclusions:
- Lactose intolerance is prevalent in healthy adults, with nearly half exhibiting symptoms.
- Lactose tolerance tests are valuable for assessing milk tolerance.
- Further research into ethnic variations in lactose intolerance is warranted.
