High-Quality Carbohydrates and Fiber Linked to Healthy Aging in Women: JAMA

Key Findings

• Of 47,513 participants, 3,706 (7.8%) were included in the study's healthy aging criteria.

• For each 10% increment in calorie consumption from total carbohydrates, there was a 17% increased chance of healthy aging (OR 1.17; 95% CI, 1.10–1.25).

• High-quality carbohydrates had an even more significant relationship with a 31% increased chance of healthy aging (OR 1.31; 95% CI, 1.22–1.41).

• Refined carbohydrates were inversely related to healthy aging (OR 0.87; 95% CI, 0.80–0.95).

• Intake of carbohydrates from fruits, vegetables, and whole grains was associated with advantages, with ORs of 1.11 (95% CI, 1.07–1.15) to 1.37 (95% CI, 1.20–1.57) per 5% increment in energy.

• intake of dietary fiber was also associated with an improved likelihood of healthy aging, with ORs of 1.07 (95% CI, 1.03–1.11) to 1.17 (95% CI, 1.13–1.22).

• Greater dietary glycemic index (GI) and carbohydrate-to-fiber ratio were negatively correlated with healthy aging, with ORs of 0.76 (95% CI, 0.67–0.87) and 0.71 (95% CI, 0.62–0.81), respectively.

This study revealed that higher consumption of high-quality carbohydrates and dietary fiber was associated with a higher likelihood of healthy aging among women. These findings emphasize the importance of taking notice of carbohydrate quality in health maintenance later in life.
