What Should I Know?
Tea and coffee contain polyphenols that can inhibit iron absorption when consumed with meals.
This is especially important for people at risk of iron deficiency.
It’s better to drink tea and coffee at least 1–2 hours after eating.
Why Does It Matter?
Iron is essential for carrying oxygen in the blood and for energy production. Drinking tea or coffee during meals may reduce iron absorption, which can increase the risk of anemia, especially for women, children, and people following plant-based diets.
What Do the Rules and Science Say?
Polyphenols are natural compounds found in plants with various health benefits. However, they can bind to dietary non-heme iron and reduce its absorption in the gut.
How Does It Work?
Polyphenols can form insoluble complexes with iron, especially non-heme iron from plant foods, making it harder for the body to absorb. This effect is most significant during the digestion phase, particularly in the small intestine.
Why Does It Taste or Feel This Way?
Although tea and coffee can leave a refreshing or clean taste in the mouth after eating, their timing matters. For better nutrient absorption, it’s best to delay their consumption after meals.
What Are the Common Misconceptions?
“Black tea is unhealthy” → Not true. It’s not about the tea itself, but about when you drink it.
“Herbal teas are safe” → Some herbal teas also have high polyphenol content and can affect iron absorption too.
