excerpt from CONCLUSIONS:
The consumption of added sugars in the diet of older people was associated with frailty, mainly when present in processed foods.
excerpt from RESULTS:
Compared with participants consuming <15 g/d added sugars (lowest tertile), those consuming ≥36 g/d (highest tertile) were more likely to develop frailty (OR: 2.27; 95% CI: 1.34, 3.90; P-trend = 0.003). The frailty components “low physical activity” and “unintentional weight loss” increased dose dependently with added sugars. Association with frailty was strongest for sugars added during food production. Intake of sugars naturally appearing in foods was not associated with frailty.
