Iron is an essential mineral that is involved in various bodily functions, including the transport of oxygen in the blood. Iron is found in meat, eggs, leafy green vegetables, and iron-fortified foods. If you don't eat meat, you may need to increase your intake of iron-rich, plant-based foods. Iron deficiency can lead to anemia, a condition where the body does not have enough healthy red blood cells. Anemia is often the result of inadequate dietary intake and/or blood loss. So, which diets may not include enough iron?
| Characteristics | Values |

| Diet Type | Gluten-free diet, Vegan diet |
| Risk Factors | Nutritional deficiency, Non-heme iron reliance |
| Symptoms | Fatigue, Low immunity, Poor productivity, Fibromyalgia, Restless legs syndrome |
| Recommended Action | Consult a doctor or dietitian, Include iron-rich foods, Take iron supplements |

What You'll Learn
Vegetarian or vegan diets
Vegetarian and vegan diets can provide enough iron, but it may be more difficult to meet iron requirements due to the type of iron consumed in these diets. Heme iron, found in animal products, is generally easier for the body to absorb than non-heme iron, which is found in plant-based sources. As a result, vegetarians and vegans may need to consume up to 80% more iron than those who eat meat.
Good sources of non-heme iron for vegetarians and vegans include:
- Whole wheat bread, cereals, pasta, quinoa, and oatmeal
- Dried apricots, raisins, and dates
- Dried beans and legumes
- Dark green leafy vegetables
- Nuts and seeds
- Iron-fortified products
To enhance the absorption of non-heme iron, it is recommended to pair these foods with ingredients rich in vitamin C. Examples of vitamin C-rich foods include oranges, tomatoes, and potatoes. Additionally, consuming vitamin C-rich foods with iron-rich plant foods can improve absorption.
While it is important to ensure adequate iron intake, excessive iron can be harmful, and iron supplements should only be taken after consulting a doctor.

Diets without iron-rich foods
Iron is an essential mineral that is a part of haemoglobin, which helps maintain strength and energy. It is necessary for forming healthy red blood cells, which carry oxygen throughout the body. Iron is also needed to make new blood cells, replacing the ones lost through blood donations.
Iron deficiency can lead to anaemia, which can leave you tired and short of breath. If you are worried about your iron levels, it is important to speak with your doctor.
Some diets may not include enough iron, leading to a potential deficiency. Here are some diets that may be low in iron:
- Vegetarian and vegan diets: Research shows that vegetarians and vegans are at a higher risk of iron deficiency due to their reliance on non-heme iron, which is less absorbable by the body. Plant-based sources of non-heme iron include lentils, chickpeas, spinach, kale, kidney beans, and whole-wheat bread. However, these sources may not provide sufficient iron if not properly combined with other foods. For instance, lentils and chickpeas need to be paired with foods high in vitamin C, such as citrus juices, to enhance iron absorption.
- Gluten-free diets: Gluten-free diets can also lead to potential iron deficiencies. Many gluten-free products may have lower iron content compared to their gluten-containing counterparts. Individuals on a gluten-free diet should be mindful of their nutritional intake and include iron-fortified gluten-free cereals or grains to meet their iron requirements.
- Infants and children: Infants, especially those with low birth weight or born prematurely, may not get enough iron from breast milk or formula. After six months, it is recommended to introduce iron-enriched cereals or pureed meats to boost iron intake. Children, particularly during growth spurts, require extra iron, and a lack of a healthy, varied diet may put them at risk of anaemia.
- Frequent blood donors: People who routinely donate blood may be at risk of iron deficiency anaemia as blood donation depletes iron stores in the body. Eating more iron-rich foods can help remedy this issue.

Fad diets
Iron deficiency can lead to a range of health issues, including iron deficiency anaemia, which is characterised by low haemoglobin levels and a decrease in the number of red blood cells. This can cause symptoms such as fatigue, restless legs syndrome, and poor productivity.
Adolescent girls and women of reproductive age are at a higher risk of iron deficiency due to iron loss through menstruation and growth spurts during puberty. Restrictive fad diets that limit food choices can further increase the risk of iron deficiency in these populations.
Vegetarian and vegan diets, which are sometimes considered fad diets, can also lead to iron deficiency since they rely on non-heme iron, which is less absorbable by the body. Gluten-free diets, another type of fad diet, can also result in iron deficiency if gluten-free packaged foods are not fortified with iron or included as part of a diverse diet.
To prevent iron deficiency, it is important to include a variety of iron-rich foods in the diet, such as red meat, liver, oysters, kidney beans, spinach, and whole-wheat bread. In addition, vitamin C enhances iron absorption, so eating iron-rich foods alongside vitamin C-rich foods or drinks can improve iron levels.

Lack of variety in diets
Iron is an essential nutrient for the body to function normally. It is required to make haemoglobin, a molecule found in red blood cells that carries oxygen through the body. Iron is naturally present in many animal-based foods, such as red meat, liver, and oysters. Plant-based sources of iron include kidney beans, spinach, kale, raisins, and apricots.
A lack of variety in diets can lead to iron deficiency, especially in children, who may be fussy eaters. A varied diet is essential to ensure adequate intake of iron and other nutrients. Here are some ways to increase dietary variety to meet iron requirements:
Firstly, for those who follow a plant-based diet, it is important to consume a greater variety of iron-rich plant foods. This is because plant-based sources of iron, known as non-heme iron, are less absorbable by the body. Vegetarians and vegans are at a higher risk of iron deficiency due to the reliance on non-heme iron sources. By including a wider range of plant-based iron sources, such as lentils, chickpeas, and iron-fortified cereals, the risk of deficiency can be reduced. Additionally, pairing these foods with vitamin C-rich options like oranges, tomatoes, and broccoli can enhance iron absorption.
Secondly, individuals on a gluten-free diet may also be at risk of iron deficiency if they do not carefully select their foods. Gluten-free products often have lower nutrient content, including reduced iron levels, compared to their gluten-containing counterparts. To ensure adequate iron intake, those on a gluten-free diet should include a variety of naturally iron-rich foods, such as meat, fish, and gluten-free cereals fortified with iron. Consulting with a nutritionist can help individuals on a gluten-free diet make informed choices to meet their iron requirements.
Furthermore, it is important to be mindful of other factors that can contribute to iron deficiency when aiming to increase dietary variety. For example, blood loss during menstruation can lead to reduced iron levels in women. Additionally, chronic conditions such as gastrointestinal issues or intestinal parasites can impact iron absorption and deplete iron stores. Therefore, addressing these underlying issues and incorporating a diverse range of iron-rich foods can help prevent iron deficiency.

Diets without vitamin C
Iron is an essential nutrient for the body to function normally. Iron deficiency can lead to anaemia, poor productivity, fibromyalgia, and restless legs syndrome. While iron is found in many foods, vitamin C helps the body to absorb iron. Therefore, diets that do not include enough vitamin C may lead to iron deficiency.
Vegetarians and vegans are at a higher risk of iron deficiency due to their reliance on non-heme iron, which is less absorbable. In addition, gluten-free diets can lead to nutrient deficiencies if gluten-free packaged foods are not fortified or included in a diverse diet. Many gluten-free products may be lower in nutrients, including iron, compared to their gluten-containing counterparts.
To avoid iron deficiency, vegetarians and vegans can pair iron-rich foods like lentils and chickpeas with vitamin C-rich foods like oranges, lemons, kiwis, tomatoes, broccoli, berries, and Brussels sprouts. Gluten-free diets can be supplemented with iron-fortified gluten-free cereals or grains.
It is important to note that iron and vitamin C are both essential for a healthy body. While iron helps prevent anaemia by forming healthy red blood cells, vitamin C supports the immune system and aids in the formation of collagen, which is important for bone health.
