Boost Your Diet: The Benefits of Iodine and Iron Fortification in Everyday Foods

As health professionals, we know that a balanced diet is essential for optimal health and well-being. However, even with the best intentions, it can be challenging to get all the necessary nutrients from our diet alone. That’s where fortified foods come in. Fortification is the process of adding vitamins and minerals to food to boost its nutritional content. At Unilever, we believe that fortification is one of the key ways to addressing macronutrient deficiencies and have taken a strong position on food fortification in our products you can read about it here.

Micronutrient Deficiencies

The most widespread micronutrient deficiencies globally are those related to iron, iodine, zinc, and Vitamin A. In addition, inadequate intakes of Vitamin D, Vitamin B12, folate, and calcium are also known significantly to impact people’s health. In this article, we will explore the benefits of iodine and iron fortification in everyday foods and how it can help prevent micronutrient deficiencies.

Iodine and iron are two critical micronutrients necessary for proper body functioning. Iodine is crucial for thyroid hormone production, which helps regulate metabolism and development, while iron is essential for the formation of hemoglobin that carries oxygen in the blood. Deficiency in either of these nutrients can cause various health problems, including anemia, goiter, and developmental delays. Iodine deficiency can lead to health issues such as goiter, hypothyroidism, and cretinism, which can cause severe physical and mental disabilities. Iodine fortification of food is a cost-effective and sustainable solution to prevent and treat iodine deficiency disorders. Iron deficiency is the most common micronutrient deficiency worldwide, particularly in vulnerable populations such as pregnant women and young children.

Fortification is an effective way to increase the availability of micronutrients like iron and iodine in the diet, particularly in populations where nutrient deficiencies are prevalent. It is a safe and cost-effective way to improve the health and well-being of populations. Fortification can also improve the nutritional value of staple foods and can be a useful tool to address nutrient deficiencies, particularly in vulnerable populations such as pregnant women and children. Iodine fortification has been successful in reducing the prevalence of iodine deficiency disorders. It can improve cognitive development in children, reduce the risk of stillbirths, and improve overall health outcomes. Iodine fortification can also be an effective strategy to reduce the risk of thyroid cancer.

What are the most Fortified Foods?

The most fortified iodine foods include salt, bread, dairy products, and seafood, particularly seaweed. The World Health Organization recommends iodization of salt to improve iodine nutrition. Iodine fortification has been successful in reducing the prevalence of iodine deficiency disorders and improving cognitive development in children, reducing the risk of stillbirths, and improving overall health outcomes. Iron-fortified foods include cereals, bread, pasta, rice, and other grains, as well as meat, poultry, fish, and eggs. However, the iron from plant-based sources is not as easily absorbed by the body as the iron from animal sources, which is why vegetarians and vegans may need to consume more iron-rich foods or consider taking iron supplements to meet their daily requirements.

Iron fortification has many benefits for human health, such as improving energy levels, cognitive function, and immune system function. It can also improve growth and development in children and reduce the risk of preterm birth and low birth weight in pregnant women. Iron fortification can have economic benefits by reducing healthcare costs associated with iron deficiency and anemia.

In addition to the presence of fortified foods, there are what is known as super-fortified foods which are designed to provide optimal levels of nutrients to people who may have difficulty meeting their daily requirements. These foods may contain additional nutrients such as vitamin A, vitamin D, vitamin C, folate, zinc, and calcium, as well as iodine and iron. Super-fortified foods form part of the foods consumed daily in most households, and they include milk, breakfast cereals, bread, pasta, rice, baby foods, and nutritional supplements. These foods can help prevent nutrient deficiencies, improve overall health and well-being, and reduce the risk of chronic diseases such as heart disease, diabetes, and cancer. That’s why it’s important to include the right foods as part of your daily intake to ensure you’re getting the nutritional benefits of fortified and super-fortified foods to boost your daily requirements.

Reading food labels is important for identifying fortified foods and understanding their nutrient content. Food labels list the nutrients and their quantities per serving, as well as the daily value (DV) percentage. The DV percentage indicates how much of a nutrient is in one serving of the food compared to the daily recommended intake. For example, a food with a DV of 20% for iron means that one serving contains 20% of the daily recommended intake for iron.

Knowing the recommended daily intake of iodine and iron is important to ensure that you are getting enough of these essential nutrients in your diet. The recommended daily intake of iodine and iron varies based on age, sex, and other factors such as pregnancy and lactation. Here are the recommended daily intake levels for iodine and iron:

Adding fortified foods to your meals can be an easy and effective way to ensure that you are getting enough iodine and iron in your diet. Here are some tips for incorporating fortified foods into your meals:

• Choose whole foods that are naturally rich in nutrients, such as fruits, vegetables, and whole grains, and supplement them with fortified foods.
• Look for products that are fortified with iron and iodine, such as breakfast cereals, bread, and milk.
• Add a handful of iron-fortified cereal to your yogurt or sprinkle it over your fruit salad for an extra nutrient boost.
• Use iron-fortified flour to make bread or baked goods.
• Add iodized salt to your meals instead of regular salt.

While fortified foods can be a great source of essential nutrients, there are some foods that you should avoid when consuming fortified foods. Here are some foods to avoid:

• Foods that are high in phytates, such as whole grains, legumes, and nuts. Phytates can interfere with the absorption of iron and other minerals.
• Foods that are high in calcium, such as dairy products, can also inhibit the absorption of iron and should be consumed in moderation.
• Avoid consuming excess amounts of fortified foods, as this can lead to nutrient toxicity.

Fortified foods can be a convenient and effective way to increase the intake of essential micronutrients in the diet. The addition of iodine and iron to everyday foods has significant health benefits and can help prevent common nutrient deficiencies. Super fortified foods offer an even higher nutrient density, making them an ideal choice for individuals with special dietary needs.

As health professionals, it is important to educate our patients on the benefits of fortification and encourage them to incorporate fortified foods into their diet. By understanding how to read food labels and choose nutrient-rich whole foods, patients can easily incorporate fortified foods into their daily meals. It is important to note that fortified foods should not be relied upon as a substitute for a balanced diet. A healthy and balanced diet that includes a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats is essential for optimal health and well-being.

In conclusion, the benefits of fortification in everyday foods cannot be overstated. By incorporating fortified foods into our diets, we can help prevent nutrient deficiencies and improve our overall health. As health professionals, we have an important role to play in educating and encouraging our patients to make healthy food choices that include fortified foods. Let’s work together to promote a healthy and balanced diet for all.
