Q1. Which of these is more easy to digest vegetarian food or non vegetarian food and why?
Answers
Answer:
Non vegetarian food digests faster, but this is not a good thing. When you digest proteins, this is a simple matter of using normal animal processes for separating amino acids.
Plant fiber is actually digested, not by us, but by our gut bacteria allies (some of these also eat animal compounds, but we are healthier if we keep a high fiber-eating/flesh eating ratio). This process occurs well down into the intestines, and recent research implies that not only is a significant amount of the work of digestion done by these bacteria, these also represent some of the most important parts of digestion.
The story is complicated, but for one example, compare the roles of butyrate and hydrogen sulfide. Butyrate is generated by bacteria in our intestines and is absorbed into our intestinal wall, where it helps to support the lining in our intestine protecting us from invasion. The bacteria in question produce butyrate when they are fed appropriate types of fiber (and obviously there is no such thing as fiber that comes from animals).
Hydrogen sulfide, on the other hand, attacks the intestinal lining (and also is the reason intestinal gas can smell like rotten eggs). There are several factors in how much hydrogen sulfide is generated during digestion 1) how much protein you eat, and 2) what percentage of the amino acids in the protein are the sulfur-containing proteins found in higher concentrations in meat. 3) Is the protein present in small enough quantities to be digested by the stomach or does some of it survive to be processed by gut bacteria of the less friendly sort. A fourth possible factor is, what is the volume of everything else?, as that can reduce concentrations and therefore damage, but I am ignoring that for now.
Meat digests relatively quickly, but not all of it. As far as I know, our stomachs are designed to digest proteins in a healthy way so that we don’t need to worry too much about the rapidly digested part. But then a little bit leaks out. If you have been feeding these bacteria and they are present in large enough quantities to process significant amounts of the remaining protein then that would lead to the hydrogen sulfide that causes problems.
So, best would be to just eat vegetables. Second best would be to first eat your salad (or fiber source) then meat, and worst would be to eat the meat first, then a a source of bulk that would push more animal protein out of stomach digestion faster.
Depends.
There are vegetarian foods that take quite long to digest and there are non vegetarian foods that digest fairly quickly.
For instance, some starchy foods like those made from refined and bleached wheat flour can be quite hard for the human digestive system to break down, and will give the consumer the feeling of being "full" for a longer time, whereas most types of sea foods are broken down quite easily, even when fried, like a lot of varieties of fish.
The human system though tilts towards alkalinity whereas those of predators are acidic. Human digestive system involves a rather narrow but long passage through the intestines whereas those of a tiger for instance are shorter and wider, and being acidic, can digest meats in raw form a lot better.
If you want to keep your human system in top shape, a good variety of foods, not missing on fruits and vegetables, is quite essential. If you're looking for foods that are easy to digest, then avoiding dense carbohydrates and red meat is important.
