This is a great graphic that’s an excellent summary of a paleo/primal way of eating:
Gillian's paleo/primal food pyramid
What I like about it is how it emphasizes that:
- grains, beans/legumes, and added sugars are the essential foods to avoid
- dairy is optional; while strict Cordain-style paleo makes dairy a no-no, other versions of the diet include dairy, especially from grass-fed animals, as it provides great fats and fat-soluble nutrients
- starchy veggies are optional; strictly speaking, carbs aren’t essential (the body can generally manufacture the glucose it needs), but many starchy veggies are nutrient-packed, and including them gives you more flexibility wrt meals
- olive oil is not a cooking oil; you’re better off cooking with saturated fats
Update, 1/14: I originally posted this giving the credit to someone who hadn’t created the graphic. It’s now properly attributed.
