Have alot of different questions and though ive read the answer to many by searching the net there are some left id like more input on.
How effective is our digestive system compared to animals and insects? What are the major differences?
How long does it take for nutrition entering the stomach to entering the bloodstream?
How long does it take for nutrition entering the bloodstream to be consumed by the body entirely?
If you neglect to chew your food proparly will it affect the energy gain of the food, or cause your body to have to work harder to digest it?
Food goes to the blood, and so the blood gives energy and mass to the body. Does this mean that scientifically we literally are what we eat?
Is there a huge difference in eating food in forms of real food or powder/pills?
If a person is fed lots of food and the blood of this person is drawn and injected into the bloodstream of a person that is halfway to die from starvation, will the recipents body be able to benefit from his blood/nutrition considering they have the same blood type?
Ive heared one of the reasons human ancestors got smarter was beginning to cook their meat with fire/heat, is this a myth? If it is true why does it matter for the body if the meat is cooked or raw and how does this affect intelligence?
Is it true calorie intake and age are related?
From wiki:
Severe caloric restriction has been found to reduce reactive oxidative species and to increase the life-span of rodents, possibly by promoting mitohormesis. Studies have shown that both calorie restriction and reduced meal frequency or intermittent fasting can suppress the development of various diseases and can increase life span in rodents by 30-40%
Does this seem to indicate eating food damages the body over time due to the "bad" stuff in the food in addition to the nutritions we need? Are digestion and age related somehow? and...
Are there any PURE food sources that have little to none "bad stuff"?
Are there any modernday alternatives to giving the body nutrition without using our digestive system?
Is it scientifically possible in theory to make the human body get its energy from somewhere else, or will the body still need food to apply mass?
Sorry for long post, hopefully somene is bored enough to answer some of them.
