Your body eliminates used hormones through the gut. If you are 'backed up' due to low fiber, those hormones can actually be reabsorbed into your bloodstream, worsening the symptoms of estrogen dominance.
The Estrobolome
This is the group of bacteria in your gut specifically tasked with metabolizing estrogen. They thrive on fiber. By feeding your estrobolome, you are helping your body maintain a more stable hormonal environment.
