Lactose intolerance: an unnecessary risk for low bone density.

Area of Science:

• Nutrition Science
• Gastroenterology
• Bone Health

Background:

• Lactose intolerance affects 25-50 million Americans and an unknown global population, leading to milk avoidance.
• Milk avoidance is a significant risk factor for low bone density and increased osteoporosis risk.
• Individuals avoiding milk often have lower calcium intake and poorer bone health.

Purpose of the Study:

• To highlight the prevalence and impact of lactose intolerance on bone health.
• To discuss effective management strategies for lactose intolerance.
• To project the growing challenge of lactose intolerance with expanding dairy markets.

Main Methods:

• Literature review on lactose intolerance prevalence and health impacts.
• Analysis of dietary calcium intake and bone health in milk-avoiding populations.
• Examination of management strategies for lactose intolerance.

Main Results:

• Lactose intolerance necessitates milk avoidance, impacting calcium intake and bone density.
• Effective management includes adapting gut bacteria, consuming low-lactose dairy, and using digestive aids.
• Global dairy market expansion may increase lactose intolerance prevalence.

Conclusions:

• Lactose intolerance poses a significant public health challenge, particularly for bone health.
• Accessible management strategies can mitigate the negative health consequences of lactose intolerance.
• Global education and product innovation are crucial for managing lactose intolerance worldwide.
