Dietary acrylamide and physical performance tests: A cross-sectional analysis.

Area of Science:

• Nutrition Science
• Gerontology
• Biochemistry

Background:

• Dietary acrylamide, prevalent in heat-processed foods, is linked to increased inflammation and oxidative stress.
• The impact of dietary acrylamide on physical performance remains largely unexplored.
• This study focused on individuals with knee osteoarthritis or at high risk, a population susceptible to physical decline.

Purpose of the Study:

• To investigate the association between dietary acrylamide intake and physical performance.
• To examine this relationship in a large cohort of North American adults with or at high risk for knee osteoarthritis.

Main Methods:

• Dietary acrylamide intake was assessed using a food frequency questionnaire and categorized into quartiles and deciles.
• Physical performance was measured via the 20-meter usual pace walk, 400-meter walk, and chair stands test.
• Linear regression analysis, adjusted for confounders, was employed to determine associations.

Main Results:

• A cohort of 4,436 participants (mean age 61.3 years) was analyzed.
• Individuals in the highest quartile of acrylamide intake exhibited significantly longer times for 20m walk, 400m walk, and chair stands.
• Increased dietary acrylamide (per decile) was significantly associated with poorer performance in all physical tests.

Conclusions:

• Elevated dietary acrylamide intake is significantly correlated with diminished physical performance.
• These findings suggest a potential role for acrylamide as a risk factor for sarcopenia.
• Further research is warranted to elucidate the mechanisms linking acrylamide exposure to muscle health.
