Over 2 billion cups of tea are consumed daily worldwide, but concerns about contaminants persist. So, does tea have harmful chemicals? While mostly safe, some varieties can contain compounds from natural sources, environmental factors, or processing that warrant attention.

Tannic acid, a form of hydrolysable tannin, is a naturally occurring polyphenol found in a wide variety of plants, including tree bark, leaves, and unripe fruits. The availability of tannic acid depends on whether you are seeking small quantities from everyday sources or purchasing a specific grade for commercial or scientific use.

The flavor of green tea, which originates from the same plant as black tea (*Camellia sinensis*), can vary dramatically, from a delicate, sweet whisper to a bold, grassy punch. The notion of its inherent "strength" is a common misconception, as its final taste is profoundly influenced by how it is prepared.

Tannins are a group of naturally occurring chemical compounds, also known as polyphenols, found in many plant-based foods and drinks like wine and tea. But what do high tannins do to your body and your sensory experience? They are responsible for the distinctive astringent and bitter sensations in many of our favorite foods and beverages.

Research consistently demonstrates that certain compounds in tea significantly hinder the body's ability to absorb iron, particularly the non-heme variety found in plant-based foods. This inhibitory effect is a key consideration for those at risk of iron deficiency or those following vegetarian and vegan diets.

Research has long established that drinking tea with an iron-rich meal can significantly reduce the body's ability to absorb non-heme iron. The question that often arises is, do all teas block iron absorption, or does the impact depend on the type of tea and its preparation? The answer lies in understanding the active compounds present in your cup.

According to a study published in the American Journal of Clinical Nutrition, consuming tea simultaneously with a meal significantly reduces non-heme iron absorption. This effect is primarily caused by compounds in tea that can bind to iron, leading many to question, "Can drinking tea lower your iron levels?".

According to health experts, drinking tea immediately after a meal can significantly interfere with nutrient absorption, particularly iron, due to compounds called tannins. This makes the timing of your chai consumption a crucial factor for maximizing its potential health benefits and supporting digestion.

According to research, black tea typically contains the highest concentration of tannins, ranging from 27% to 55%, due to its extensive oxidation process. This high tannin content is responsible for black tea's robust, dark character and pronounced astringency.

According to tea experts, the dry, puckering sensation felt when drinking tea is called astringency, a mouthfeel distinct from dehydration. If you have wondered 'Why does matcha dry out my mouth?', the answer lies in its unique chemical composition and preparation.
