In an earlier post, I wrote about the association between biomarkers of systemic acid-base balance (serum bicarbonate, the anion gap, urinary pH) with all-cause mortality risk (https://michaellustgarten.com/2015/08/28/serum-bicarbonate-and-anion-gap-whats-optimal/). Based on these data, systemic acidity may not be optimal for health and longevity, when compared with more alkaline values. Can circulating acid-base biomarkers […]

In a previous post, with the goal of reducing all-cause mortality risk I wrote about obtaining (at least) 1000 micrograms of Vitamin K per day. To do that, I’ve begun making pineapple-spinach smoothies! To make it, I used 8 oz of fresh pineapple, which I put in the freezer for […]

How much selenium is optimal for health? To address this question, I’ll examine the association between circulating levels of selenium with all-cause mortality risk. Then, I’ll identify a dietary selenium intake that corresponds to optimal plasma selenium levels. Let’s have a look! A variety of studies have investigated associations between plasma (or serum) selenium with […]
