How to Boost Iron Levels

Learn how to boost iron levels on a whole food, plant-based diet: effective strategies and a food-first approach


As we age, the risk of iron deficiency can increase because of decreased absorption and dietary changes. For people over 40 following a whole food, plant-based diet, ensuring adequate iron intake is so important for maintaining energy levels, supporting cognitive function, and overall health.


Understanding Iron Needs

Iron is a vital mineral involved in transporting oxygen in the blood, energy production, and immune function. There are two types of dietary iron:


  • Heme Iron: Found in animal products and is more easily absorbed by the body.

  • Non-Heme Iron: Found in plant foods and is less readily absorbed but can be optimized with certain strategies.

Does this mean a plant-based diet is inferior to an omnivore diet? Let's break it down.


The myth that a whole food, plant-based diet isn't healthy because non-heme iron is less readily absorbed than heme iron oversimplifies the complexity of nutrition and ignores several important considerations. Here's why this statement is not true:


1. Getting Enough Iron on a Plant-Based Diet

While it's true that non-heme iron, found in plant foods, is not as easily absorbed as heme iron from animal products, this doesn't mean that a plant-based diet is deficient or unhealthy! Plant-based diets can provide enough iron through a variety of foods, including legumes, whole grains, seeds, nuts, and leafy greens. With just a little planning, you can easily meet your iron needs on a plant-based diet.


2. Enhancing Iron Absorption

Non-heme iron absorption can be increased by pairing iron-rich plant foods with vitamin C-rich foods, like citrus fruits, tomatoes, bell peppers, and broccoli. Vitamin C converts iron into a form that is easier for the body to absorb. Additionally, reducing the intake of substances that inhibit iron absorption, such as calcium, polyphenols in tea and coffee around mealtimes can also improve iron uptake.


3. Health Benefits of a Plant-Based Diet

A well-balanced plant-based diet is associated with numerous health benefits, including lower risks of chronic diseases such as heart disease, hypertension, type 2 diabetes, obesity, and certain cancers. These benefits are partly due to the amount of fiber, antioxidants, vitamins, minerals, and healthy plant compounds, as well as lower intake of saturated fats

and cholesterol.


4. Ethical and Environmental Considerations

Choosing a plant-based diet aligns with ethical considerations regarding animal welfare and has a significantly lower environmental impact compared to diets high in animal products. This includes reduced greenhouse gas emissions, lower water usage, and less land needed for food production.


5. Balanced Approach to Nutrition

No diet is perfect, and all dietary patterns require attention to nutrients. Just as omnivores need to be mindful of obtaining sufficient fiber, antioxidants, and minimizing saturated fat, those on both an omnivore and plant-based diet need to pay attention to nutrients like iron, vitamin B12, omega-3 fatty acids, and others. Both diets can be healthy if well-planned and balanced.


6. Nutrient Availability and Absorption

While heme iron is more bioavailable, it is not without its own potential downsides. High intake of heme iron has been linked to increased risks of certain health issues, including colorectal cancer and type 2 diabetes. In contrast, the body has ways to regulate non-heme iron absorption more effectively, potentially reducing the risk of iron overload.


A whole food, plant-based diet, just like an omnivore diet, can be healthy with proper planning. The difference in iron absorption between non-heme and heme iron is just one aspect of nutrition and doesn't undermine the overall health benefits of a plant-based diet. With an understanding of how to optimize nutrient intake, individuals can thrive on a plant-based diet and enjoy a range of health, ethical, and environmental benefits!

How to Boost Iron Levels: Strategies to Enhance Iron Absorption


Pair Iron with Vitamin C:


Why It Matters: Vitamin C enhances the absorption of non-heme iron.

How to Do It: Add vitamin C-rich foods to your meals, such as citrus fruits, bell peppers, tomatoes, strawberries, and broccoli.


Avoid Inhibitors During Meals:


Why It Matters: Certain compounds can inhibit iron absorption.


How to Do It: Limit tea and coffee consumption during meals because they contain polyphenols that inhibit iron absorption.

Avoid eating high-calcium foods or supplements with iron-rich meals as calcium can interfere with iron absorption.


Soak, Ferment, and Sprout:


Why It Matters: These processes reduce phytic acid, a compound that can inhibit iron absorption.

How to Do It: Soak beans and grains before cooking, incorporate fermented foods like tempeh, and try sprouting seeds and legumes.


Cook with Cast Iron:


Why It Matters: Cooking with cast iron pans can increase the iron content of your food.

How to Do It: Use cast iron cookware for cooking acidic foods like tomatoes, which can help leach more iron into your meals.


Optimize Meal Timing:


Why It Matters: The body’s iron absorption can vary throughout the day.

How to Do It: Try to consume iron-rich meals earlier in the day when the body’s ability to absorb iron may be higher.


Regular Blood Testing:


Why It Matters: Monitoring iron levels helps you understand if you’re meeting your needs or if you require adjustments.

How to Do It: Schedule regular check-ups with your healthcare provider to monitor iron levels and adjust your diet or supplement intake as necessary.


Supplements


While focusing on learning how to boost iron levels with a food-first approach, some people may still need supplements to maintain adequate iron levels:

  • Choosing a Supplement: If necessary, opt for a high-quality iron supplement such as ferrous bisglycinate, which is gentle on the stomach and well-absorbed.

  • Consultation: Always consult with a healthcare provider before starting any supplement to determine the appropriate dosage and to avoid potential interactions with other medications.



How to Boost Iron Levels

Maintaining adequate iron levels on a whole food, plant-based diet is entirely achievable with mindful dietary choices and strategies. By incorporating iron-rich foods, enhancing absorption, and considering supplements if necessary, women over 40 can effectively manage their iron levels and enjoy the numerous health benefits of a plant-based diet.
