Optimizing Biological Age: Albumin

In an earlier post, I showed published data that albumin levels decrease with aging, and that lower levels are associated with an increased all-cause mortality risk (https://michaellustgarten.com/2018/07/06/serum-albumin-and-acm/). I also showed my own blood test data (n=11), which included a strong correlation for albumin with my dietary intake of beta-carotene (= 0.75). Since then, I’ve measured my albumin levels an additional 9 times, with 20 total measurements that correspond to my tracked dietary intake. With more data, did the strength of this association get better, stay the same, or get worse?

The correlation for albumin with my dietary beta-carotene intake weakened slightly (r = 0.66), but the p-value strengthened (p = 0.0015 vs. p = 0.007):

alb update

Albumin is an important variable for predicting biological age, as demonstrated by its inclusion on the aging.ai and PhenoAge (https://michaellustgarten.com/2019/09/09/quantifying-biological-age/) calculators. If your albumin levels aren’t close to 5 or greater than 4.5 g/dL if you’re a man or woman, respectively, you may want to consider increasing your beta-carotene intake, especially if you’re interested in optimizing biological youth. Each day, I get most of my beta-carotene  from about a pound of carrots, but also from a few ounces of spinach.

If you’re interested, please have a look at my book!

    1. That’s great, but have you checked your albumin levels since? Let your biomarkers guide your dietary intake…

    2. How many carrots cause Carotenemia?
      According to a Columbia University health blog, “for carotenemia to set in, you might have to consume as much as 20 milligrams per day (or, three large carrots).” While the condition is seen in adults, it is most common in infants and children, according to the Scientific American.Mar 22, 2016

    1. Those foods don’t affect my albumin, but do the experiment, maybe it will work for you!

Optimizing Biological Age: RDW%

Wed Sep 25 , 2019
Can biological age be optimized? The red blood cell (RBC) distribution width (RDW%) is one of the variables included in the PhenoAge biological age calculator (see https://michaellustgarten.com/2019/09/09/quantifying-biological-age/). Although the RDW% reference range is 11.5% – 14.5%, what values are optimal in terms a youthful biological age, and minimized disease risk? […]
