Higher scores on five distinct dietary indices (Nutrition Index, E-DII, HEI-2015, MDS, DASH) are significantly associated with increased risk of frailty and higher 8-year mortality risk in adults across all ages.
Adhere to established healthy dietary patterns such as the Mediterranean, DASH, or HEI-2015 guidelines. These patterns, which emphasize fruits, vegetables, whole grains, and healthy fats while limiting processed foods and added sugars, are associated with a lower risk of frailty and mortality. You do not need to track every nutrient; focusing on the overall quality of your diet is sufficient to gain these benefits.
higher NI and E-DII scores and lower HEI-2015, MDS, and DASH scores were individually significantly associated with frailty. All dietary scores were significantly associated with 8-year mortality risk after adjusting for basic covariates and frailty
Why this rating
Large sample size (N=15,249), longitudinal follow-up (up to 8 years), and adjustment for multiple confounders.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
