The Truth About Aluminum in Tea with Lemon

The idea that combining tea with lemon leads to Alzheimer's disease is rooted in the presence of aluminum in tea leaves, but a closer look at the science reveals a much more reassuring reality. Aluminum is naturally abundant in the earth's crust and is washed by water into the soil, where it is inevitably absorbed by growing plants. The tea bush is particularly adept at taking in this element because aluminum indirectly promotes the plant's growth by helping it absorb and utilize phosphorus.When you brew tea, some of this aluminum transfers into the water. Adding lemon introduces citric acid, which lowers the pH of the tea and causes even more aluminum to leach from the leaves into the beverage. Furthermore, while the naturally occurring aluminum in tea is very poorly absorbed by the human digestive system and mostly excreted, combining it with citric acid creates a compound called aluminum citrate. Due to specific transport molecules in the body, aluminum citrate is capable of crossing from the digestive tract into the bloodstream much more easily than unbound aluminum.Despite this chemical reaction, the actual numbers show there is little cause for alarm. A liter of black tea brewed for five minutes typically contains between 5.5 and 8 mg of aluminum. Adding lemon juice increases this amount by 20% to 50%, resulting in 6 to 10 mg of aluminum per liter, though some teas have much lower baseline levels depending on their cultivation conditions. Toxicological guidelines establish that a safe, tolerable intake of aluminum is 2 mg per kilogram of body weight per week. For an average person weighing 60 kg, this translates to a safe intake of 120 mg per week, or about 17 mg per day. If an average cup of tea contains roughly 1.5 mg of aluminum, drinking three cups a day only accounts for about 25% of the daily safe limit, leaving a massive safety margin.Crucially, the body's actual absorption of aluminum citrate is still extremely low, remaining well below 1%. While it is technically absorbed better than pure aluminum, the absolute amount entering the bloodstream remains completely microscopic. Clinical tests have proven that drinking 500 ml of tea with lemon daily does not lead to any significant increase of aluminum levels in the blood. This is because only a fraction of the aluminum in the tea actually binds with the citric acid in the first place.For a typical adult drinking around three cups of tea with lemon per day, there is absolutely no toxic threat or elevated risk of illness. However, parents should be slightly more cautious with children; because children have a lower body weight, drinking three to four cups a day could bring them closer to their maximum safe limit.If there is still lingering concern about aluminum exposure, there is an incredibly simple solution: brew the tea, completely remove the leaves or tea bags, and only then add the lemon juice. Since the citric acid only causes aluminum to leach from the physical leaves, adding lemon to an already strained infusion entirely prevents the increase of aluminum. Ultimately, drinking tea with lemon is completely safe, and treating it as a severe health hazard is largely unwarranted.Become a supporter of this podcast: https://www.spreaker.com/podcast/whole-life-studio--6886552/support.
