Written by Harold Oster, MD. A prebiotic supplement may improve measures of frailty in older adults. Frailty is usually defined as an age-related decline in function and reserve that reduces the ability to cope with external stressors. It is associated with an...
Mediterranean Diet and Ultra-Processed Food on Frailty in Older Adults
Written by Chrystal Moulton, Science Writer. Ultra processed foods were associated with a higher risk of frailty (RR= 1.10, P < 0.05) and pre-frailty (R= 1.04, P < 0.05). The life expectancy of adults over 70 years old has significantly increased in the past two...
Omega-3 Intake Is Negatively Associated with Phenotypic Aging
Written by Chrystal Moulton, Science Writer. Researchers observed a significant negative correlation between omega-3 intake and phenotypic age acceleration [beta= -0.4, P < 0.001]. Omega-3 fatty acids DHA and EPA are essential components of cell membranes that are...
Beneficial Effects of an Astragalus-Based Supplement on Telomere Length
Written by Harold Oster, MD. Results suggest that an Astragalus-based supplement may increase telomere length in adults. Astragalus, also known as Huang qi, is a plant commonly used in traditional Chinese medicine1. Various species of astragalus contain astragaloside...
The Association Between Vitamin D Levels and Inflammation in Older Adults
Written by Harold Oster, MD. The study suggests that vitamin D deficiency is associated with increased inflammation in older adults. Acute inflammation is necessary in the immune system’s response to infection. Chronic inflammation, however, contributes to the...
Key Nutrients Associated with Acceleration /Deceleration in Aging
Written by Chrystal Moulton, Science Writer. The top three nutrients contributing to accelerated/decelerated aging based on the weighted quantile sums index were copper (19.36%), alcohol (21.71%), and beta-carotene (21.60%) even after adjusting for covariates....
The Association of Vitamin D Supplementation with the Rate of Epigenetic Aging
Written by Harold Oster, MD. Results suggest that vitamin D supplementation in deficient individuals is associated with slower epigenetic aging. Vitamin D deficiency leads to bone loss and the increased likelihood of fractures. Severe deficiency is associated with an...
The Effect of a Prebiotic Supplement on Cognition and Muscle Strength in Older Adults
Written by Harold Oster, MD. Results suggest that daily consumption of a prebiotic supplement is associated with improved cognition in older adults. The prevalence of dementia is increasing with the aging of the population1. Sarcopenia is an age-related condition of...
A Combination of NAC and Glycine Promotes Healthy Aging in Older Adults
Written by Taylor Woosley, Science Writer. 16-week supplementation with 100 mg/kg of glycine and 100 mg/kg of NAC significantly improved glutathione concentrations by 164% and resulted in a significant reduction in IL-6 by 78%, TNF-α by 54%, and hsCRP by 41% in older...
Higher Intake of Berries Associated with Lower Allostatic Load
Written by Taylor Woosley, Science Writer. Findings of a cross-sectional research analysis of 7684 NHANES participants shows that consumers of total berries (p=0.0026), strawberries (p=0.013), and blueberries (p=0.008), respectively, had significantly lower mean AL...
