gel their hands on. The two questions we have to look at are: How
long did they live on that diet? What diet for humans gives them the
best protection against disease and the greatest chance for longevity
in modern times?
Personally, 1 want to do a lot better than our prehistoric ancestors
did. A comprehensive overview and a sensible interpretation of the
scientific evidence support the conclusion that we can increase hu-
man longevity and prevent disease if we make specific food choices.
We still retain our primate physiology, a physiology that has a de-
pendence on high vegetation consumption, that is relevant to ex-
plain our ability to thrive on a plant-predominant diet.
Dr. Katerine Milton, from the University of California at Berke-
ley, is among the few nutritional anthropologists in the world who
has worked with and studied cultures and primitive peoples not
influenced by modern technology. She has concluded that the diet of
both primitive people and wild primates is largely plant-based.^13 The
main difference between primitive diets and our own is their con-
sumption of nutrient-dense wild plants and the lack of access to low-
nutrient, high-fat foods such as cheese and oil, as well as refined
grains.
We have a unique opportunity in human history: We have fresh
produce being flown into our food stores from all over the planet.
We can take advantage of this abundant variety of fresh vegetation
to eat a diet with more phytochemical density and diversity than
ever before. We have the opportunity to make decisions about what
we eat that were not available to our prehistoric ancestors. Fortu-
nately, we have knowledge that they lacked, and we can use this
knowledge to live longer than ever before.
I know you do not recommend butter or margarine,
so what do we put on bread, vegetables, or corn?
Butter is loaded with a dangerous amount of saturated fat, but stick
margarines have hydrogenated oils that contain trans fats that raise
LDL, the bad cholesterol. Adjusting the type of fat consumed, re-
searchers found that butter caused the highest cholesterol level and
that varying amounts of margarines and oils had various harmful ef-
fects.^14 The best answer is to use nothing, or buy whole-grain bread
that tastes good without adding a greasy topping. If you love the fla-
vor of butter, try Butter Buds or sparingly use a spread that contains
no hydrogenated oil, such as Spectrum Essential Omega Spread, in-
