Interesting, but many parts of the videos compares carnivorous and herbivorous, with very brief mentions of omnivorous. Even when omnivorous are mentioned, the point is dismissed simply by saying that "omnivorous retain features similar to carnivorous so as to hunt".

I think what she is setting out to say is simply that we have traits of herbivores and given the fluid spectrum that omnivores are in it makes more sense to err in that direction

Also, many points about the design of our physiology (esp the parts about our teeth and jaws) are compared to carnivorous that have to hunt with their teeth/claws, while humans utilise tools and thus do not need the same canine teeth etc. Humans could simply have started off as herbivorous and adapted to become omnivorous, while keeping many of the herbivorous traits as we circumvent the need of carnivorous adaptations by utilising tools.

Yes, this is exposition to claim we started off not as carnivores but like many other great apes herbivores (specifically frugivores). The most important question I think is whether our digestive systems are optimised for plant based foods or animal based foods

lot of the other points about stomach sizes etc, doesn't take into the account that humans have learnt to store, preserve and cook food, so we do not need to have the same design as most carnivorous. E.g. the point about the low pH of stomach which is required to kill bacteria in decaying flesh.

I think the most important thing she sets out to prove is that diets high in meat aren't good for our health. Cholesterol in meat leads to atherosclerotic plaque formation in humans but it doesn't in any other true carnivore or omnivore on the planet. Heart disease is the number one killer of people in rich countries with diets high in meat. That's just the tip of the iceberg, there's a lot of other research that suggests meat consumption isn't optimised for long term health.
