Theine caffeine8/15/2023 ![]() ![]() Very Toxic to Animals You should never give coffee or tea to pets. It’s estimated that nearly one quarter of adults worldwide are “hooked” on caffeine. As little as one cup of coffee or two of tea a day (about 100 mg of caffeine) can lead to physical dependence and, if you stop drinking them, sometimes serious withdrawal symptoms. There is also the risk of developing a physical dependence on caffeine. The amount of caffeine found in energy drinks and diet pills is much greater than in a typical cup of coffee or tea (there are about 100 mg of caffeine in the average cup of coffee, but 300 mg in a typical energy drink) and either product can lead to an overdose and even death, especially in adolescents, if abused. However, caffeine isn’t always as innocuous as we like to think. Note that we don’t know why coffee seems good for our health and that these benefits don’t necessarily come from caffeine: coffee contains about 1,500 chemicals and only very few have been studied. Drinking one or two coffees a day seems to help protect against Parkinson’s disease, diabetes and various liver diseases including cancer, improves cognitive function and reduces the risk of depression. In addition, several studies indicate that coffee, tea and yes, even chocolate can be beneficial for your health, at least in case of adults. Our body simply digests these alkaloids as with so many other products we ingest. As a result, most people think of caffeine and theobromine as being rather innocuous. ![]() Moreover, some adults drink three or four cups a day without suffering any major sequel. It’s said that it’s the dose that makes the poison and so is it with caffeine and theobromine: the amount present in a cup of coffee, tea or hot chocolate (or a glass of Coca Cola or Pepsi) is insufficient to kill a human. Both caffeine and theobromine are xanthine alkaloids.Īre Caffeine and Theobromine Toxic to Humans? Café in reasonable quantities is harmless and even beneficial to most adults. Theobromine, present in the cacao tree ( Theobroma cacao), plays a similar role. And the caffeine/theine in tea plants serves the same purpose: to repel or kill insects that attack the plant. Note that theine, produced by the tea plant ( Camellia sinensis) and present in tea, is actually just caffeine: the two are chemically indistinguishable. Several companies are working on deriving an organic pesticide from caffeine and other similar substances. Caffeine-treated mosquito larvae, for example, become so poorly coordinated that they can no longer swim and end up drowning. Source: loraDid you know that caffeine is an insecticide? Moreover, that the coffee plant ( Coffea arabica and others) produces it in order to protect itself from predatory insects? When under attack by unwanted invertebrates, moreover, the coffee plant increases the dose of caffeine, often producing enough to kill the intruder.Ĭaffeine extracts applied to various insects (milkweed bugs, caterpillars, mosquito larvae, etc.) cause agitation, reduce appetite, inhibit reproduction, and can even lead to death. The coffee plant ( Coffea arabica), a common houseplant, produces its own insecticide: caffeine.
