Iron is an essential nutrient to the body as it is a necessary component of haemoglobin. Iron deficiency affects the delivery of oxygen.
High Iron Requirements
Generally, during periods of fast growth, pregnancy and menstruation, iron requirements increase. In such cases, there is a risk of developing anaemia.
Low Iron Absorption
Studies suggest that some diseases and surgeries may impair iron absorption. If such conditions prolong, they may lead to iron deficiency.
Blood Loss
Blood loss in any form may cause iron deficiency anaemia. It can occur due to various reasons. For example, it may result from blood loss due to injury, menstruation, etc.
Diet
Studies suggest that the absorption of iron depends on several nutritional factors. Among that, vegetarian and vegan foods have low-quality iron called non-heme iron that non-vegetarian
Vitamin C
It is an essential nutrient for iron absorption. Vitamin C rich foods may convert iron to an easily absorbable form.

Polyphenols
They associate with nonheme iron in the gut and prevent absorption. In addition, one of the polyphenols, Tannic acid, is present in tea.
