Nutrient-dense foods

Nutrient-dense foods are widely embraced for supporting growth, digestion, and overall health.

Strong consensus

“the animal meat and these unprocessed foods that I just mentioned they they're the most convenient punching bag”

Regenerative agriculture

Regenerative agriculture supports soil health and more nutritious food for people and planet.

Strong consensus

“there's a movement of regenerative agriculture which is fascinating which is using animals to help build soil which then sequesters carbon retains water and raises animals that have much higher quality meat and don't contribute to climate change and actually help reverse climate change”

Meal prep is a warmly recommended habit for nourishing, low-stress eating.

Strong consensus

“if you take two hours on sunday ... cutting up your vegetables cooking in bulk maybe blending a bunch of smoothies ... we literally have all of our green smoothies for the entire week prepared”
