Meat digestion

[Diana]

Since you mentioned dairy and the lactose intolerance...

I wonder how much of the intolerance is due to:
(1) Milk cows fed grains instead of grass (bad).
(2) Pasteurization that destroys the enzymes in the milk needed to digest it properly.
(3) Hormonal injections of the cows.
(4) More stuff to numerous to list.

I think the biggest thing of the intolerance is the pasteurization/homogenization.

One thing about adults and dairy. I suffered for years with lower than average weight... I couldn't gain weight no matter what or how much I ate... always "skinny". I happened to find a source of raw cow milk and consumed several gallons of it over the course of a month. Miraculously, I gained 25 pounds of much needed frame weight. I looked healthy and normal for the first time in my life.

I don't think dairy is a problem if we have an unadulterated source... just like meat.

This thread is about meat, so I'll leave it as is.

You are wrong about dairy and lactose intolerant. Lactose intolerant is because a person is missing the enzyme needed to digest lactose.

Dairy is definitely a problem even if it's raw. For one thing, it's meant for calves, not humans. Beyond that, the list is long why it's bad for humans, the animals, and the planet.

Regarding the OP:

Our Teeth, Jaws, and Nails

Humans have short, soft fingernails and small “canine” teeth. In contrast, carnivores all have sharp claws and large canine teeth that are capable of tearing flesh.

Carnivores’ jaws move only up and down, requiring them to tear chunks of flesh from their prey and swallow them whole. Humans and other herbivores can move their jaws up and down and from side to side, allowing them to grind up fruit and vegetables with their back teeth. Like other herbivores’ teeth, humans’ back molars are flat for grinding fibrous plant foods.

Dr. Richard Leakey, a renowned anthropologist, summarizes, “You can’t tear flesh by hand, you can’t tear hide by hand. Our anterior teeth are not suited for tearing flesh or hide. We don’t have large canine teeth, and we wouldn’t have been able to deal with food sources that require those large canines.”

Stomach Acidity

Carnivorous animals swallow their food whole, relying on extremely acidic stomach juices to break down flesh and kill the dangerous bacteria in it, which would otherwise sicken or kill them. Our stomach acids are much weaker in comparison, because strong acids aren’t needed to digest prechewed fruits and vegetables.

Intestinal Length

Animals who hunt have short intestinal tracts and colons that allow meat to pass through their bodies relatively quickly, before it can rot and cause illness. Humans’ intestinal tracts are much longer than those of carnivores of comparable size. Longer intestines allow the body more time to break down fiber and absorb the nutrients from plant-based foods, but they make it dangerous for humans to eat meat. The bacteria in meat have extra time to multiply during the long trip through the digestive system, increasing the risk of food poisoning. Meat actually begins to rot while it makes its way through human intestines, which increases the risk of developing colon cancer.

Human Evolution and the Rise of Meat-Heavy Diets

If it’s so unhealthy and unnatural for humans to eat meat, why did our ancestors sometimes turn to flesh for sustenance? Author of the book The Power of Your Plate, Dr. Neal Barnard, talks about humans’ early diet, explaining that we “had diets very much like other great apes, which is to say a largely plant-based diet …. [M]eat-eating probably began by scavenging—eating the leftovers that carnivores had left behind. However, our bodies have never adapted to it. To this day, meat-eaters have a higher incidence of heart disease, cancer, diabetes, and other problems.”
