The discussion revolves around the health implications of unpurified water and junk food, exploring how the body processes these substances and the potential consequences of their consumption. Participants examine the body's ability to reject harmful substances, the nature of poisons, and the nutritional value of junk food.
Participants express differing views on the body's ability to reject harmful substances and the health implications of junk food. There is no consensus on whether certain junk foods can be considered harmless or the extent of their impact on health.
Participants note that the body's digestive and immune systems have limitations, and there are unresolved questions about the mechanisms by which the body processes various substances, including the specifics of how poisons and junk food affect health.
Some poisons are absorbed and do damage before they can be removed.Doesn't our body rejects what it doesn't need? Then why do we die when we take poison? Unless our system can't digest it and get it out of its system I guess.
A neurotoxin is a toxin that acts specifically on nerve cells – neurons – usually by interacting with membrane proteins such as ion channels. Many of the venoms and other toxins that organisms use in defense against vertebrates are neurotoxins. A common effect is paralysis, which sets in very rapidly. The venom of bees, scorpions, pufferfish, spiders and snakes can contain many different toxins. Many neurotoxins act by affecting voltage-dependent ion channels. For example, tetrodotoxin and batrachotoxin affect sodium channels, maurotoxin, agitoxin, charybdotoxin, margatoxin, slotoxin, scyllatoxin and hefutoxin act on potassium channels, and calciseptine, taicatoxin and calcicludine act on calcium channels.
http://en.wikipedia.org/wiki/Organophosphate - which are also used in insecticidesNerve agents (also known as nerve gases, though these chemicals are liquid at room temperature) are a class of phosphorus-containing organic chemicals (organophosphates) that disrupt the mechanism by which nerves transfer messages to organs. The disruption is caused by blocking acetylcholinesterase, an enzyme that normally relaxes the activity of acetylcholine, a neurotransmitter.
Snake poison is used to make anti-venom, which is used to counteract the snake venom (poison).Also of the science where when a person is biten by a snake, snake poison is used to treat him. How do those things work?
http://en.wikipedia.org/wiki/Junk_food - neutrality of article is questioned, but the paragraph cited pretty much sums up the situation accurately.Junk food typically contains high levels of fat, salt, or sugar and numerous food additives such as monosodium glutamate and tartrazine; at the same time, it is lacking in proteins, vitamins and fiber, among others. It is popular with suppliers because it is relatively cheap to manufacture, has a long shelf life and may not require refrigeration. It is popular with consumers because it is easy to purchase, requires little or no preparation, is convenient to consume and has lots of flavor. Consumption of junk food is associated with obesity, heart disease, Type 2 diabetes and dental cavities. There is also concern about the targeting of marketing at children.
Skhandelwal said:So that would be mean that some kind of junk food are not bad for us b/c our body rejects them, right? Could you tell me which one those are? lol
ganstaman said:I think it could be helpful if you figured out (and told us) exactly what you mean by 'reject.'
Danger said:It's 'state of the art' in terms of human evolution. This isn't something that we can immediately alter on a whim.
There are many ways that the body can get in poor health from eating the wrong things.Skhandelwal said:I guess what I am trying to say is that when you eat something, if it has proteins, the body takes it from it and supplies it to(btw, where to the things we eat go?) but the rest flushes out. Are you saying that when body choose to select something out of something, it gets a little bit of bad stuff too b/c its filter is not the state of the art?
Our bodies did not evolve with an abundance of food, this is a relatively recent event of the modern world to not experience periods of famine or low food availability. Our bodies are very efficient at storing excess calories as fat reserves whenever we encounter them. Junk food (along with even the excesses of otherwise "healthy" food available and consumed in modern society) gets converted into fat very easily. While there is a healthy and necessary amount of fat reserves (this is discussed in another thread you started) to lubricate and cushion organs and to maintain energy reserves between meals, when this is greatly exceeded, as it is in many people today, it becomes pathological. As with many things, too little or too much fat are both problems for our bodies. Too much fat means we are experiencing metabolic problems associated with processing the excess (diabetes), cardiovascular problems from the excess lipids in our blood stream (atherosclerosis), musculoskeletal problems from carrying around that excess weight all day long, and further cardiovascular and respiratory problems from trying to pump blood through so much body mass.Skhandelwal said:I guess what I am trying to say is that when you eat something, if it has proteins, the body takes it from it and supplies it to(btw, where to the things we eat go?) but the rest flushes out.
