This one suggests that age acceleration is associated with lower strength and/or loss of strength over time in US adults aged 51 years and older, followed over an 8-10 year period.
- "A growth in research evidence documents that epigenetic phenomena, such as DNA methylation (DNAm), are highly implicated in the development of disease and rate of biological ageing...
"...Given that methylation profiles are thought to be modifiable by lifestyle and other environmental factors, it has been proposed that DNAm age is a robust biological ageing clock providing a superior estimate of true biological age over chronological age...
"...A number of epigenetic clock measures have been generated for measuring an individual's epigenetic age, and in particular, to indicate accelerated or decelerated biological ageing (i.e. as compared with chronological age)."
- The objective of this study was to determine the association between grip strength and DNA methylation age acceleration derived from three epigenetic clocks trained on phenotypic ageing (i.e. age-related health conditions/profiles) and mortality.
- The age, sex and racial breakdown of the study's sample "is consistent with that of Americans aged 50 years and older in the USA, based on U.S. census data".
- Among middle-aged and older men and women, lower grip strength per body mass was associated with DNA methylation age acceleration across several clocks.
- This may suggest that greater strength may be protective against DNA methylation age acceleration.
- Caveat: The associations between grip strength and age acceleration clocks were not consistent across sex categories in the fully adjusted models:
In the analyses of the follow-up data, stronger grip strength per body mass was inversely associated with GrimAgeAA and DunedinPoAmAA in both men and women, but only PhenoAA in men.
In the analysis of the baseline data, only DunedinPoAmAA was statistically significantly associated with grip strength per body mass in both men and women, whereas GrimAgeAA and PhenoAA were both statistically significant in women.

The findings of this one support that even plant-based unhealthy dietary choices can be harmful towards metabolic health, as they exhibit a positive association with liver steatosis prevalence.
- The overall plant-based dietary index (PDI), the healthful plant-based dietary index (hPDI) and the unhealthful plant-based dietary index (uPDI) were used to assess one's diet.
- The PDI corresponds to the overall adherence to a plant-based dietary pattern irrespective to the quality of plant-based products consumed.
Here, leisure-time sedentary behavior was associated with the risk of dementia incidence and mortality, but replacing it with a short duration of physical activity was associated with a decreased risk of dementia, with the effect being stronger in APOE ε4 carriers.
- The apolipoprotein E (APOE) gene is the strongest genetic factor modulating risk for Alzheimer's Disease and dementia.
This gene has three common alleles, the protective allele APOE ε2, the neutral allele APOE ε3, and the risk allele APOE ε4.
This systematic review and meta-analysis suggests that nut consumption is likely to reduce serum triglycerides in healthy adults with overweight/obesity, and LDL-c when incorporated in one's habitual diet.
- "Subgroup analyses for serum lipids revealed that the favorable effect of nuts on serum TG was more pronounced in population with a mean BMI <30 kg/m2 and in a follow-up duration <12 weeks...
"...Moreover, in the subgroup analysis based on the type of diet, nut consumption led to a significant decrease in LDL-C in those following a normocaloric diet."
This one in Iranian adults found higher dietary oxalate intakes to be associated with an increased risk of developing hypertension and chronic kidney disease, especially when consuming lower calcium intakes.
- Compared to high-calcium consumers, subjects with lower calcium intake (< 1180 mg/d) had a higher risk of both CKD and hypertension.
- Interestingly enough, no statistically significant association was observed between dietary oxalate and the outcomes in subjects who consumed dietary calcium above the median.
This systematic review and meta-analysis finds the triglyceride glucose (TyG) Index to be a reliable, effective tool that can be used for the screening of metabolic syndrome.
- "A significant association of the TyG index with MetS was reported in all included studies, indicating the potential reliability of the TyG index as a new index for screening MetS...
This one found an inverse association between folate intake and colorectal cancer risk, while identifying 3 genes with suggestive interactive effects between total folate consumption and colerectal cancer risk: GSTA1, TONSL, and AGA.
- An inverse association between folate intake and colorectal cancer risk was observed.
- The study also identified 3 genes with suggestive interactive effects between total folate consumption and colorectal cancer risk: GSTA1, TONSL, and AGA.
