I eat home made food as daily consumption. In my house we used to have a day (Friday) which was called "Junk Food Day", where we bought McDonalds for breakfast and some fried chicken or sandwich for lunch.
The breakfast caused me symptoms like diarrhea, well, I wasn't the only one at home suffering the same. It was like our weekly laxative. Somehow bacteria or some ingredient in that food caused me to have such reaction.
Junk Food Day was necessary, because the body must get used to junk food. You are always exposed to eat junk food when you travel driving a car, when you are with friends going out, etc.
So, to prevent a unfavorable reaction, the body must have some knowledge of that kind of food.
On the other hand, a glass of juice has way more sugar than a soda. Lots of vegetables in restaurants have been sprayed with additives to maintain them fresh. Who knows how long ago the delicious chicken soup has been prepared in a restaurant.
In other words, eating healthy really requires lots of care, taking your own food for lunch time at work, and things like that.
But, lets go further. The chicken you buy at the market is a genetically modified chicken produced in miles long underground factories. These chicken never see sun light, live in cages, fed on food running in a feeder canal in front of them, the poo poo of these chicken goes to a river running under the cages, the poo poo goes to a processor machine which separates 65% of it to be mixed with additives and return back to the feeder canal.
This is how healthy is the chicken sold in most of the USA.
About fish... the same. Growth in pools, where even with the most care, they will end eating their own excrement, plus the water is not purified properly, in other words, that fish is completely different than the one from a natural environment. For example, Salmon from the river has the flesh orange going to red. The fish is not "fat" because travels a lot and the body is "fit", and, of course, "smells".
On the other hand, salmon from pools, are fat, the flesh is from orange to white, and it doesn't have strong smell.
You must pay "extra" to eat "healthy fish".
About fruits, for example. The worst that the food industry has made is producing fruits without seeds. You have no idea how bad becomes eating seedless fruits. You think you are eating "healthy" but seedless fruits lack of ingredients which by nature serve as protectors of your health. When you eat seedless fruits you are eating sugary food only, the natural protection against some diseases is missed.
The food industry practically has destroyed the meaning of "healthy food". The worst is that our bodies get used to junk food and demand the "drug" and reject healthy food. Children will prefer a soda over having a fresh made lemonade or orange juice made with fruits with seeds. As snack sweet cookies will be over an apple, or Doritos over a healthy sandwich with lettuce and tomatoes included.
And about bodies and health.
As long as the individual is not obese, being overweight is not unhealthy. In many cases a heavy body is by inheritance, and there is nothing wrong with the individual but was born with heavy bones and require of more flesh surrounding it. As long as walking, running, playing a sport is a routine, being overweight is not much an issue.
Main thing is what we eat. I myself don't follow rigorously a healthy food consumption, but I don't abuse eating junk food.
I can just suggest you to please yourself considering that what you eat will cause consequences in your body, and if not today, then later on, you will suffer a lot because the poor health in your latter years.
At least, think about it.
There is nothing that isnt genetically modified. Genetic modification is the base for evolution.
Definitively you have not seen "that" artificially genetically modified chicken, I think is R57 or similar name, with atrophied legs and other degraded characteristics.
Such is not evolution but yuck yuck yuck chicken, eating back 65% their own doo doo... yuck yuck yuck... These chicken have not even flavor... I saw the documentary... apparently you ignore what are you eating when you go to those cheap carry out stores and when you buy cheap chicken at the food markets.
Forget about silly and stupid theories which won't take you anywhere, because those make you live in a world of fantasy.
The miles underground chicken factory was even published in magazines of science in the 60's. In those publications, same as you read about your theory, everything looks clean and neat "in paper", but in reality those underground factories are zombie movies alike, with deformed creatures eating excrement mixed with additives.
But, yes, you better live your world where, how is it? of yes, species live better without wings, without teeth, without fingers, without legs, and so forth. Lol
You seem to be happy believing those ideas.
I'm just telling you that in your diet when you eat chicken in carry outs you are consuming 65% doo doo chicken.(*)
(*) In nature, birds like chicken might consume about 10% of their own doo doo. They are animals and when no other food is available like worms and similar, they just eat what they have available, but this is a minimum level of this kind of consumption.)
