Article Synopsis
  • Magnesium is crucial for enzymes that help regulate glucose and insulin metabolism, and low dietary intake may increase the risk of metabolic syndrome (MS) in older adults.
  • The study analyzed data from 535 adults (aged 60+) in Boston, evaluating their magnesium intake and its relationship with MS and related risk factors using food records and logistic regression models.
  • Results indicated that higher magnesium intake was linked to a significantly lower risk of MS and improved measures like BMI and fasting glucose levels, suggesting older adults should consume more magnesium-rich foods like green vegetables and whole grains.

Compared with younger adults, older people experience additional health, social, and environmental conditions that affect their dietary intake. To identify those additional dimensions and examine them in association with fruit and vegetable intake, data of 4,622 participants in NHANES III (1988-1994), ages 60 years and over, were analyzed using multivariate logistic regression modeling. Results showed that participants at highest risk of consuming fruits and vegetables in the lowest quartile were those socially isolated, with missing pairs of posterior teeth, with poor self-reported health and those who were obese.

Background: Whole-grain intake has been inversely associated with the metabolic syndrome in middle-aged populations, but the association has not been investigated in older adults. The metabolic consequence of consuming high whole-grain diets may differ in elderly persons, who are prone to greater insulin resistance and impaired glucose tolerance.

Objective: The aim of the present study was to examine the cross-sectional association between whole- and refined-grain intake, cardiovascular disease risk factors, prevalence of the metabolic syndrome, and the incidence of cardiovascular disease mortality in the same cohort of older adults.
