Today’s interesting fact has to do with what type of food our ancestors ate.

From studying bones and teeth, and the various isotopes found within them, they have found they can accurately determine the diet of the creature they are studying as well as where the animal grew up and if it moved from one area to another.

From their studies we know that before 10,000 BC, the average human ate average of probably 65% plant to 35% animal derived foods.

After 10,000 BC depending on where they were in the world, this changed to as high as 90% plant to 10% animal derived foods.

Before 10,000 BC humans got their animal protein from various sources.

In order of decreasing importance to the diet or if you prefer the amount they ate, we have insects or their grubs, small lizards, mammals and birds, fish, shellfish, and the occasional large animal.

It is also interesting to note that before 10,000 BC, the average human was taller, stronger and healthier than after 10,000 BC when they became weaker, shorter and had more infections.

There are multiple reasons for the decrease in health the ancients but one they have positively identified is the switch to a more vegetarian diet.
