Coffee. We all know its benefits, and by now we also know that it may not make everyone as active because of the coffee glitch. But could it be harmful? The European Union says so. But, why? Recently, the European Union or the EU has issued a warning that caffeine is "harmful to humans if swallowed". The EU under a ruling banned the use of the central component of coffee in pesticides.the decision came from the European Commission, which is the executive arm of the economic bloc. This decision was in response to an application by a French company Progarein. Caffeine was used to ward off insects from crops of cabbages and potatoes.Coffee is a daily essential for millions around the world, with Europe being the largest consumer market for the drink. But while caffeine is widely consumed in beverages, its potential use in agriculture has raised safety concerns.The European Commission has officially banned caffeine as a pesticide, citing scientific evidence from the European Food Safety Authority (EFSA) on its risks to human health and the environment.Health Risks Linked With Caffeine ExposureAccording to the EFSA, caffeine can have several adverse effects, including:Cardiovascular Issues – Caffeine can impact heart health, raising concerns for adults.Nervous System Effects – It may contribute to sleep disturbances, anxiety, and behavioral changes in both adults and children.Pregnancy Risks – Studies suggest caffeine exposure is linked to lower birth weight in newborns.Unknown Non-Dietary Risks – The EFSA was unable to fully assess the effects of caffeine exposure on workers, bystanders, and nearby residents due to a lack of data.Given these concerns, the commission concluded that caffeine could pose risks beyond dietary consumption when used in farming.Environmental Concerns - Water ContaminationOne of the key reasons for banning caffeine as a pesticide was its potential to contaminate water sources.Drinking Water Safety – The EFSA found that caffeine levels from agricultural use would “significantly” exceed safe concentration limits in drinking water.Surface Water Exposure – Large amounts of caffeine could end up in rivers and lakes, affecting ecosystems and aquatic life.These findings reinforced the commission’s decision to prohibit its use in agriculture.What Should You Know About Coffee? Not always coffee is bad, in fact, a study published in the European Heart Journal by Dr Lu Qi, the lead researcher and director of Tulane University Obesity Research Center and team found that drinking coffee in the morning reduces the risk of heart diseases. The study also found that people who drank coffee in the morning had a lower risk of dying from cardiovascular disease and a lower mortality risk than all-day coffee consumers.The Coffee Glitch: While many people also choose coffee over any other beverage to make themselves active and get them through the Monday blues, it does not work on everyone. Dr Karan Rajan, gastrointestinal surgeon, author, and lecturer who posts health content on his Instagram channel @drkaranrajan talks about coffee and the glitch it causes to some people, which is why they feel tired.The way your body responds to caffeine depends on a type of liver enzyme called CYP1A2. This enzyme affects how sensitive your body is to caffeine. The doctor says, "depending on your metabolism, it could take between two to eight hours to remove half of the caffeine" you have drunk from your system. This is important because caffeine blocks the adenosine receptors, these are the hormones that tells us when we are sleeping.However, if you metabolize coffee faster, your receptors will be unblocked sooner and you will feel tired.
