  • Investigating vitamin D as a performance enhancer
    Having sufficient vitamin D levels has been associated with better muscle recovery. This trial not only looks at the question of causality, but also addresses some potential mechanisms of vitamin D’s benefit for exercise.
  • Trans fats: “natural” might not mean “healthy”
    In the nutrition community, a common message has been that artificial trans fats are bad, however natural trans fats are not only okay but beneficial. This trial on blood lipids puts that to the test.
  • High versus low fat diets for insulin sensitivity
    More body weight means more risk for metabolic syndrome. But the question of whether more fat (and especially saturated fat) impacts insulin sensitivity hasn’t been adequately addressed until now.
  • Exercise, with a (tart) cherry on top!
    Berries have burst onto the research scene in recent years. Tart cherries have shown some of the most promise in certain areas, leading to this study of powdered tart cherry on exercise recovery.
  • Interview: Dan Pardi MS PhD(c)
    Dan Pardi is an entrepreneur and researcher whose life’s work is centered on how to facilitate health behaviors in others.
  • Root rage: The impact of ashwagandha on muscle
    So called “adaptogens” like ashwagandha are typically studied for stress-easing potential. A randomized trial looked into this popular herb for a different purpose: bolstering adaptations to weight training.
  • Does the Food Guide make my butt get fat?
    By Francy Pillo-Blocka, RD
  • Antioxidants, anti-adaptations?
    We’ve covered antioxidants and strength training before. This study is a bit different — it investigates whether vitamin C and vitamin E might impact adaptations to endurance exercise.
  • I <3 green tea
    When it comes to curbing cardiovascular disease, it’s not all about reducing cholesterol. Green tea may help prevent oxidation of LDL, as is explored in this trial looking at green tea catechins both in vivo and in vitro.
  • Investigating slow carbs for metabolic rate
    Glycemic index, glycemic load, insulin index: only one of these is widely known by the public. But when it comes to keeping weight off, does glycemic index and total carb content actually have any impact?
