However it is before, tea is harmful to health after the industrialization for wide usage of pesticides. Firstly, the Chinese standard “GB” for tea is overall lower than the corresponding European one. That means the definition for a healthy tea is much lower in China. Also the soil pollution is heavy but widely ignored. Tea absorbs the plumbum(铅) from the polluted soil and that’s another issue. Secondly, the “GB” standard does not restrain the total amount of multiple pesticides altogether. That leaves the manufacturers room for using compound pesticides to seek revenue maximization and complying to GB at the same time. Whereas the high pesticide usage in tea production, the tea does not use much pesticide. We only drink the incide part of coffee fruit and shields the spreyed thing and coffee is the seed of the plant which absorbs the least harmful ingredients. The altitude for coffee growing is 1000 to 2000 km, which is not that polluted on the whole. As long as you don’t bake the coffee beans too heavy, it is much healthy from the aspect of toxics.
