Changes in Nutritional Status Through Low-Lactose Processed Milk Consumption in Korean Adults With Lactose...

Area of Science:

• Nutrition Science
• Gastroenterology

Background:

• Lactose intolerance affects many adults, often leading to dairy avoidance.
• Dietary management strategies for lactose intolerance require further investigation.

Purpose of the Study:

• To assess the impact of daily low-lactose processed milk consumption on hydrogen breath tests and nutritional status in Korean adults with lactose intolerance.

Main Methods:

• 32 Korean adults with lactose intolerance consumed 240 mL of processed milk daily for one month.
• Hydrogen breath tests and nutrient intake surveys were conducted pre- and post-intervention.

Main Results:

• Significant reductions in expiratory hydrogen levels were observed, particularly at 60 and 80 minutes post-consumption (p < 0.001).
• Participants showed significant increases in animal protein, calcium, energy from protein, vitamin A, and retinol intake (p < 0.05).
• Improvements in nutritional quotient scores, including nutritional score and balance, were noted (p < 0.05).

Conclusions:

• Daily consumption of low-lactose processed milk can be a practical dietary strategy for managing lactose intolerance.
• Individuals with lactose intolerance may not need to completely remove lactose and dairy products from their diet.
