Toxicology community spread the word: "eat more are poison," meaning that no matter what, after a certain amount can be your life. Here we cite five common everyday foods to verify this conclusion.
Please note, this is not adventure, death-defying.
Banana: 480
First, we must first ignore how to fill 480 bananas into the belly of the rationality of logic, we have to discuss is potassium. A banana contains an average of 450 milligrams of potassium, an electrolyte source is perfect. The role of potassium in our body is to maintain body fluid balance, potassium for muscle contraction and nerve impulses also have an important role. Every cell in the human body has a specific potassium ion channel.
The lethal dose of potassium consumption was 1.4 pounds, which in theory is the basic can not be achieved, but if the use of intravenous words may be easier. The influx of a large number of blood potassium concentration of high end but miserable, I think we should all know, one of potassium chloride is used when the lethal injection drugs, directly after the injection moment can cause the heart to stop beating.
Espresso: 179 cups
In the morning, bleary-eyed, just have a cup of coffee can make you the spirit of times. The intake of caffeine can lead to caffeine intoxication, which manifested as restlessness, anxiety, insomnia, nausea, rapid heartbeat and other symptoms. Under more severe cases, caffeine can over stimulate the nervous system, resulting in cardiac arrhythmia, shock.
Adult lethal dose of caffeine is about 11 grams. Caffeine intoxication is very rare, only by drinking coffee poisoning is highly unlikely, but if taken together with medicines and energy drinks, the symptoms will exacerbate.
Salt: 47 spoon
Castaway read similar stories of people should know, can not be directly drinking water. Because sea salt is too high, the body can not afford.
And potassium salts, like sodium is an important electrolyte in the body, which is responsible for regulating water out of the cell. If the sodium content of the body cellular environment is too high, in order to maintain the balance of water would flow outside the cell. This causes the cells to shrink. The most obvious symptom is hypernatremia, which primarily affects the nervous system: non-reactive, lethargy, weakness and so on. Excess salt can also cause shock or coma.
Water: 17 bottles
Yes, the water may be. Salt water intoxication and poisoning the opposite. When the body of too much water, too little salt, the cells began to absorb water, and then frantically inflate. Like brain cells, because of its closely spaced while the skull limits, no extra space expansion, will eventually lead to fatal brain damage.
In such a short time a large amount of drinking water is not common. Generally long-distance runner and taking LSD addict, because a lot of these people need to add large amounts of water and sweat. But the loss of electrolytes in sweat also need to be supplemented. We maintain fluid balance in the body is very good, sweating, urination, eating, drinking, etc., but in extreme cases it will crash the same - for example, drinking 17 bottles of water (16 oz bottle).
Toothpaste: 24
Each tube of toothpaste has stated: placed outside the reach of children under 6 years. A small amount of fluoride to prevent dental caries is good, it is undisputed, but excessive intake is harmful to health. The real lethal dose takes about 24 6 oz toothpaste, even if several children also need the whole tube. Studies have shown that in 87 years of children swallowing toothpaste accident, not a long-term effect.
In fact, there is a concept of toxicology, the median lethal dose (LD50), is capable of killing half the dose of harmful substances in the body of the experiment. LD50 different substances are different, but that does not mean there will not be less than the median lethal dose of danger. LD50 is often determined in rats and converted into per unit body weight. The data above is based on a weight of 90 kg adult estimates. Substantially all of the substances have LD50 values.
