To learn more, we tapped registered dietitians for expert insight on the matter.

Black tea is a particularly rich source, followed by green tea.

Thanks to their antioxidant properties, tannins are partially responsible for the manybenefits of tea.

Its commonly believed that tannins reduce the absorption ofiron, a mineral needed for healthy blood.

But as with most aspects of nutrition, there are caveats to consider.

If youre concerned about iron absorption or have a pre-existing iron deficiency, avoid overdrinking tea.

Heme iron is found in animal foods, including meat, poultry, and fish.

Heme iron is better absorbed by the body, while non-heme iron isnt absorbed as well, notes Salazar.

Tannins primarily affect the absorption of non-heme iron.

This means theyre less of an issue for heme iron, or iron from animal sources.

But heres the kicker: Beans, like tea, contain tannins themselves.

Tasty examples include bell peppers, tomatoes, and lemon juice.

Tofu

As far as iron goes,tofuis an excellent plant-based source.

Nuts

Nutsare another source of non-heme iron.
