Micronutrients and flavonols support healthy aging

  • Vitamins and minerals help maintain health

Doctors wondered how certain vitamins and minerals could reduce chances for developing typical, multiple chronic age-related health conditions. In this study, doctors measured the diets of 1,461 adults, aged at least 65 and average age 71, paying particular attention to calcium, folate, iodine, magnesium, potassium, zinc, and vitamins A, C, D, and E.

During an average follow-up period of 4.8 years, 561 participants developed multiple chronic conditions. Compared to those who were sufficient in these micronutrients 40.1 to 78.7 percent of the time, those who were sufficient in them 85.8 to 97.7 percent of the time were 25 percent less likely to develop multiple chronic conditions.


  • Flavonols support strength with age

Five symptoms define frailty in aging: unintentional weight loss; self-reported moderate exhaustion, some or most of the time; slow walking speed; weak hand-grip strength; and low physical activity.

In this study, doctors followed 1,701 participants, average age 58.4, without frailty at the start. Over an average 12.4 years of follow-up, 224 developed frailty. Measuring the level of flavonols in the diet, doctors found for each 10 mg per day increase in flavonols, chances for developing frailty decreased 20 percent. One particular flavonol, quercetin, showed the most benefit, with each 10 mg daily increase lowering chances for frailty by 35 percent.

Doctors said adequate flavonols in the diet reduce chances for the onset of frailty, and that quercetin appears to have the most potential as a dietary supplement for preventing frailty.
