Pumpkin seeds are often considered one of the healthiest everyday snacks. They are rich in minerals, protein, healthy fats and other bioactive compounds. But could the amount we consume matter more than we think?

In this episode of Food Code Matrix, we explore the biochemistry of pumpkin seeds and examine the proposed connections between zinc, copper metabolism, mitochondrial energy production, hormones, plant lignans and the gut microbiome.

We begin with the familiar afternoon energy crash and investigate why copper matters for mitochondrial function and cytochrome c oxidase, an essential component of cellular respiration.

We then examine zinc–copper interactions, including the role of metallothionein in intestinal mineral metabolism. The discussion moves into the more complex territory of aromatase, testosterone and estrogen m ...
