Diet therapy in adult lactose malabsorption: present practices

Area of Science:

• Nutrition Science
• Gastroenterology

Background:

• Lactose malabsorption is a common condition affecting adults.
• Dietary management is a cornerstone of managing lactose malabsorption.
• Current hospital dietary practices for lactose malabsorption may be suboptimal.

Purpose of the Study:

• To assess the availability and content of hospital diet manuals for adult lactose malabsorption.
• To evaluate physician consideration of lactose malabsorption in peptic ulcer disease patient diets.
• To propose a more evidence-based approach to dietary therapy for adult lactose malabsorption.

Main Methods:

• A survey was distributed to hospital dietitians across the United States and Puerto Rico.
• Questionnaires focused on diet therapy for adult lactose malabsorption and co-existing conditions.
• Analysis included returned questionnaires and submitted diet manual excerpts.

Main Results:

• Only 42% of responding dietitians reported having hospital diet manuals for adult lactose malabsorption.
• Less than 1% of manuals included specific diets for patients with both peptic ulcer disease and lactose malabsorption.
• Physicians frequently overlooked lactose malabsorption when prescribing diets for peptic ulcer disease.
• Many submitted diets were overly restrictive, limiting lactose-free foods.

Conclusions:

• Hospital diet manuals for adult lactose malabsorption are not widely available or adequately specific.
• There is a significant gap in the integration of lactose malabsorption considerations into dietary plans, particularly for patients with peptic ulcer disease.
• A revised, less restrictive dietary approach is recommended for managing adult lactose malabsorption.
