For instance, higher dietary fiber intake increased a capsule's time in the small intestine and led to a slight increase in
hydrogen concentration in the colon, compared with the hydrogen decrease seen on a low fiber diet.
However, the resolution of the LEND instrument is greater than the size of most PFS, so smaller PFS slopes, perhaps approaching yards in size, may have significantly higher abundances, and indications are that the
greatest hydrogen concentrations are within the permanently shaded regions, according to McClanahan.
Mean (± SE) breath -
hydrogen concentrations during the test period after the high - glycemic - index (HGI; •), low - glycemic - index (LGI; ▪), and HGI with lactulose (HGI - Lac; ▴) breakfasts.
Also, the LEND measurements over the larger EFS don't contrast with their surrounding regions, which indicates EFS have
hydrogen concentrations that are equal to their surroundings, according to McClanahan.
Exposure to hydrogen gas caused a rapid (less than 75 milliseconds) reversible decrease in the resistance of the array that correlated with
the hydrogen concentration over a range from 2 to 10 %.
But Onstott found that
the hydrogen concentrations were too high to have come from microbes and the necessary minerals aren't in the mines, which leaves radioactivity.
The abbreviation pH, stands for «power of hydrogen,» which is a measure of
the hydrogen concentration in your body.
