Deep Dive: Supplementing for senior strength and size in the context of sarcopenia
This systematic review and meta-analysis explored what supplements can stave off the loss of muscle function that comes with aging. However, the way it categorized the studies it used, along with the overall low quality of those studies, makes its conclusions seem a bit... weak.
Sugar Wars, Episode 6: The Return of the Fructose
How does fructose affect cardiometabolic risk markers calorie-for-calorie compared to glucose or sucrose? This recent meta-analysis aimed to find out.
The effects of increased protein intake on overall energy intake in older adults
Boosting protein intake may help stave off the loss of muscle strength and function that can come with age. But does increasing protein affect energy intake in older adults as well? We cover a recent meta-analysis that explored this question.
Safety Spotlight: Women and creatine
The effects of creatine are quite well studied, but its sex-specific safety profile hasn't been. Besides some non-serious side effects, creatine seems safe for women, but more work needs to understand creatine's effects during pregnancy.
NERD Mini: Dietary approaches and supplements to combat chronic pain
What nutritional interventions impact different chronic pain conditions? This NERD Mini summarizes the evidence from a systematic review released earlier this year.
Deep Dive: Determining the per-kilogram effects of weight loss on lipid levels
How much do blood lipids change for each kilogram of weight lost? This study aimed to answer this question, while also exploring whether the method of weight loss (through lifestyle, drugs, or bariatric surgery) matters much.
Deep Dive: The best non-drug ways to lower blood pressure
Drugs are usually an effective way to lower blood pressure, but non-drug interventions can help a lot, too! This network meta-analysis looked at which non-drug methods are the best for lowering blood pressure.
Deep Dive: Will nitrates improve your training performance? It depends!
Nitrates provide a small but significant performance boost, but dose, timing, and your baseline aerobic fitness matters.
Interview: Jeff Rothschild, RD, CSSD, PhD(c)
What should we eat before exercise? To find out, we picked the lead author's brain of a recent review that answers that exact question!
Deep Dive: Comparing different protein sources' impact on bone turnover
Eating more plants can be healthy but may negatively impact bone health due to lower protein, calcium, and vitamin D intake. This trial examined how the same amount of protein from animal or plant sources affected bone turnover.
Deep Dive: Does low protein intake slow down chronic kidney disease progression?
Very low protein diets seem to slow progression but don't affect mortality, raising the question of whether there's a risk-benefit tradeoff. Higher quality, larger trials could shed more light on this issue.
Deep Dive: How does alternate-day fasting compare to no diet or other diets?
ADF helps people lose weight and lower cholesterol, but there's no clear advantage over continuous energy restriction based on the current evidence. Larger, longer studies are needed, though.
