There was no lack in 2012 of animal studies to draw from to inferentially hypothesize how a human fetal environment causes the fetus to adapt … Continue reading Problematic research: Feigning naivety of the impact of prenatal, infancy and early childhood experiences

Microwave broccoli to increase flavonoid levels

This 2019 USDA study investigated representative broccoli cooking methods for their impact on kaempferol and quercetin levels: “Understanding cooking effects on flavonoids is crucial to accurately estimate their daily intake and further investigate their health benefits. The purpose of this study was not to compare different conditions of each cooking methods, but to focus on … Continue reading Microwave broccoli to increase flavonoid levels

A compelling review of epigenetic transgenerational inheritance

This 2020 review by coauthors of 2019’s A transgenerational view of the rise in obesity and Epigenetic transgenerational inheritance extends to the great-great-grand offspring summarized: “The prevalence of obesity and associated diseases has reached pandemic levels.

A pair of broccoli sprout studies

This 2015 Oregon human study found: “Plasma and urinary levels of total SFN [sulforaphane] metabolites were ~3–5 times higher in sprout consumers compared to BSE [broccoli sprout extract] consumers. In sprout consumers, plasma concentrations were 2.4-fold higher after consuming the second dose than after the first dose. Calculated SFN bioavailability from broccoli sprouts exceeded 100%. … Continue reading A pair of broccoli sprout studies
