  • S. Boulardii Hailed as a "Super Probiotic"
    Jul 21 2024

    Saccharomyces boulardii is a strain of probiotic yeast that was first isolated from the superfoods mangosteen and lychee fruit in 1923 by the French scientist Henri Boulard (hence the name). Today it is considered a "super probiotic" due to its unique properties and wide range of health benefits that set it apart from many other probiotic strains. Listen in this week as Dee discusses the key reasons why S. boulardii holds this distinction.

  • Gut Health Revolution: Apple Cider Vinegar's Role in Weight Loss
    Jul 11 2024

    Studies show that obese individuals have more Firmicutes and fewer Bacteroidetes in their gut bacteria compared to those who are not overweight. Research suggests that consuming apple cider vinegar (ACV) can help improve this ratio. Listen in this week as Dee explains ACV's impact on the gut microbiome and its role in weight loss.

  • A Newly Discovered Dietary Hazard: TMAO
    Jul 8 2024

    Trimethylamine-N-oxide (TMAO) is a harmful compound produced by gut bacteria. Elevated TMAO levels can significantly influence the development of heart disease, type 2 diabetes, chronic kidney disease, cancer, and fatty liver disease. Listen in this week as Dee explains which foods increase the production of TMAO in the gut, and how you can optimize the health of your gut.
