The teaser video doesn't look promising. The best advice in the older guidelines was to eat organ meat at least once per week. Traditional cultures universally figured this out from time immemorial. Watch pack predators and see what the alphas (who eat first) choose. For wolves its liver and heart. For Harris hawks its brain, heart and liver. Organ meats are inexpensive, giving the highest nutrition value of all foods, as they have the highest mitochondrial density.

For "Meatless" Monday I have liver, sweetbreads or brain, and save heart (meat) for later in the week.
