Episode notes
In the final episode of our micronutrient series, Greg and Lyndsey discuss which micronutrients are most worth monitoring and good food sources for the micronutrients you may be under-consuming. Then, we talk more broadly about why you shouldn’t allow a focus on micronutrients specifically to detract from the pursuit of a generally healthy diet.
