There is no single paleo diet but we are now eating toxins

There is no single paleo diet. Our ancestors ate what was available at their location. Their climates and seasons were different, so they ate different foods at the different locations and it was unlikely to be what we consider balanced today, or all vegetarian or all meat.

As time changed we evolved and changed our eating and diets from:-

Foraging- picking food and eating. No doubt some mistakes were made with people being poisoned. We were moving from place to place.

Hunting- We gained knowledge and outsmarted other animals and ate them. We boosted our strength and health with our high protein intake. We are still moving from place to place and still foraging. We are true omnivores.

Planting - About 10,000 years ago we growing things in one location, plus foraging and hunting locally.

McDonalds – We are now eating toxins.
