What to Eat to Get Enough Iron Per Day: A Complete Dietary Guide

2 min read

An estimated two billion people worldwide suffer from iron deficiency, the most common nutritional deficiency. Learning what to eat to get enough iron per day is important for health.

Quick Summary

This guide outlines dietary sources of iron and factors affecting absorption.

Key Points

Know Your Iron Types: Heme iron from animal products is more easily absorbed than non-heme iron from plant sources.
Pair Iron with Vitamin C: For non-heme sources, combining them with vitamin C-rich foods significantly boosts absorption.
Moderate Absorption Inhibitors: Compounds in tea, coffee, and dairy can hinder iron uptake. Consume these separately from high-iron meals.
Embrace Diverse Sources: A variety of foods can help meet your daily needs.
Consider Cooking with Cast Iron: Preparing meals in a cast-iron skillet can increase the iron content of your food.
Tailor Your Diet: Vegetarians and vegans can thrive on plant-based iron, but must be strategic with food pairings and preparation.

Understanding the Two Types of Iron

Iron in food comes in two primary forms: heme and non-heme. Heme iron is found in animal products like meat, fish, and poultry and is highly bioavailable, meaning the body absorbs up to 30% of it. Non-heme iron is found in plant-based foods such as grains, legumes, and vegetables. Its absorption is much lower (2% to 10%) and easily influenced by other dietary factors. While a diet including both is suitable for meat-eaters, vegetarians and vegans can meet needs by maximizing non-heme iron absorption through strategic food pairing.

Top Iron Food Sources

To ensure adequate iron intake, incorporate a variety of these foods into your diet:

Heme Iron Sources: Red meat, organ meats, poultry, and seafood are excellent sources.
Non-Heme Iron Sources: Legumes, nuts and seeds, vegetables, fortified foods, dried fruits, and dark chocolate provide valuable non-heme iron.

Boost Absorption and Avoid Inhibitors

Pairing foods can significantly impact iron absorption, particularly for non-heme iron.

How to Boost Your Iron Intake

Consuming vitamin C-rich foods with non-heme iron sources is highly effective for increasing absorption. Cooking in a cast-iron skillet can also boost the iron content of meals. The presence of meat, fish, or poultry can enhance non-heme iron absorption when consumed together.

Foods and Drinks to Moderate

Certain compounds can interfere with iron absorption, especially non-heme iron. It's best to consume these away from your main iron-rich meals. These include high-calcium foods, phytates found in whole grains and legumes (soaking or sprouting can reduce levels), polyphenols and tannins in tea, coffee, cocoa, and red wine, and phosvitin in eggs.

A Side-by-Side Comparison of Iron Sources


Feature	Heme Iron	Non-Heme Iron
Sources	Animal products	Plant sources
Bioavailability	High	Low
Absorption Pathway	Dedicated pathway	Influenced by enhancers and inhibitors
Absorption Rate	Up to 30%	2% to 10%
Impact of Diet	Relatively stable	Highly dependent on meal composition
Risk of Overload	Higher risk if consuming large quantities	Less risk of overload

Conclusion: A Balanced Plate for Optimal Iron

Meeting your daily iron needs is achievable through a varied diet. By understanding iron sources and strategically combining foods to enhance absorption while moderating inhibitors, you can optimize intake. Incorporating a mix of iron-rich foods and pairing non-heme sources with vitamin C is key. Being mindful of consuming certain items separately from iron-rich meals further supports healthy iron levels. A balanced dietary approach is essential for preventing deficiency and maintaining energy.

Disclaimer: Always consult a healthcare professional for personalized dietary advice, especially if you suspect you have an iron deficiency.

Frequently Asked Questions

Heme iron is found in animal products and is more easily absorbed by the body. Non-heme iron is found in plant-based foods, and its absorption is influenced by other dietary factors.

Some of the highest iron foods include organ meats like liver, shellfish such as oysters, and legumes like lentils and white beans. Fortified breakfast cereals are also potent sources.

Yes, it is possible for vegetarians to get enough iron. A balanced plant-based diet rich in legumes, nuts, seeds, and leafy greens can provide adequate intake, especially when combined with vitamin C-rich foods.

To increase non-heme iron absorption, pair plant-based iron sources with foods high in vitamin C, like bell peppers, broccoli, or citrus fruits. Cooking with a cast-iron pan can also help.

To maximize iron absorption, avoid consuming high-calcium dairy products, tea, coffee, and red wine at the same time as your iron-rich meals. These can inhibit the body's ability to absorb iron.

Yes, dark chocolate with 45-69% cacao solids contains a good amount of non-heme iron. An ounce provides a decent boost to your daily intake.

Iron is crucial for producing hemoglobin, which carries oxygen in red blood cells to all parts of the body. Inadequate iron can lead to fatigue, weakness, and shortness of breath.

Daily iron needs vary. Adult men (19-50) need 8mg, while adult women (19-50) require 18mg due to menstruation. Pregnant women need 27mg per day.
