    The possibility for sweat as a route of toxin excretion is intriguing.  Hussain et al. (2023) found metabolites from insecticides in the sweat of women who participated in a randomized crossover trial involving sauna and indoor cycling.  The authors noted differences in the levels detected between the two modes of inducing sweat, and between the…

    Metallothionein has been found to play a role in mitigating the adverse effects of mercury exposure (Woods et al., 2013).  Boys in Portugal with variants in the genes for metallothionein were found to exhibit more severe behavioral symptoms.  Metallothioneins are proteins that are able to bind to mercury and transport it through the body.  The…

    An association has been found between higher levels of gamma-glutamyl transferase (GGT) and serum levels of several persistent organic pollutants (Lee & Jacobs, 2006).  Also, increased oxidative stress has been found in association with elevated GGT (Lim et al., 2004).  Brassicas are emphasized in the Detox Food Plan, and consumption of cooked, frozen brassica vegetables…

    Dürr et al. (2000) gave 300 mg of St. John’s Wort to healthy volunteers three times a day for two weeks.  They found that this induced CYP3A4 in both the liver and the intestines, which explained the interactions that had been observed between St. John’s wort and certain drugs.  It seems that it reduced the…

    Stephens et al. (2013) reported new data from a randomized controlled trial by Wall et al. (2011).  In this trial, there were seven participants each in the intervention and in the placebo.  They were all moderately trained recreational athletes.  Both groups drank a beverage containing 80 g of carbohydrate twice a day, in the morning…

    The International Society of Sports Nutrition’s recommendation (Jäger et al., 2017) is that 1.4–2.0 g protein/kg body weight/day is enough to gain muscle mass, but that 3.0 g/kg/day or more can continue to be beneficial for balancing overall body composition.  They recommend consuming protein every 3-4 hours throughout the day, including before bed.  A home-cooked…

    I found an interesting study (Lino et al., 2018) that looked at the concentrations of both mercury and selenium in different species of fish in Brazil.  They found that carnivorous fish had the highest concentration of mercury and also the lowest concentration of selenium, while fish lower on the food chain were higher in selenium…

    Last week the FDA approved the first over the counter birth control pill (Belluck et al., 2023), which is expected to be widely utilized and increase use of hormonal birth control by teenagers among other demographics.  The New York Times article went on to say that the manufacturer even plans to offer ways for people…

    A strategy referred to as “sleep low-train low” involves scheduling carbohydrate intake around the training schedule so that some, but not all, workouts are performed in a state where the muscles do not have maximum glucose available to do the work.  Several randomized trials with trained male athletes have investigated the effects of this strategy…
