What food brings down your iron?

Answered by Robert Dupre

Grains, beans, nuts, and seeds are all examples of foods that can decrease your iron levels. These foods contain a compound called phytic acid, or phytate, which can reduce the absorption of iron from plant-based sources. Phytates bind to iron and form a complex that is difficult for our bodies to absorb.

Let’s break it down further. Grains such as wheat, rice, oats, and corn are commonly consumed around the world. While they provide essential nutrients and energy, they also contain phytates that can hinder iron absorption. This is particularly true for whole grains, as the phytate content is higher in the outer bran layer. So, if you rely heavily on whole grain products, it’s important to be mindful of their potential impact on your iron levels.

Beans, including kidney beans, black beans, chickpeas, and lentils, are excellent sources of plant-based protein and fiber. However, they also contain phytates, which can reduce iron absorption. This doesn’t mean you should avoid beans altogether, as they offer numerous health benefits. Instead, consider pairing them with vitamin C-rich foods, like citrus fruits or bell peppers, as vitamin C can enhance iron absorption.

Nuts and seeds, such as almonds, cashews, walnuts, sunflower seeds, and sesame seeds, are nutritious and add a delightful crunch to meals and snacks. However, they too contain phytates that can decrease iron absorption. Again, this doesn’t mean you need to avoid these foods entirely. You can enjoy them in moderation and consider soaking or sprouting them before consumption, as this can help reduce the phytate content and improve nutrient availability.

It’s important to note that the phytate content in foods can vary. Some varieties of grains, beans, nuts, and seeds may have higher or lower levels of phytates. Additionally, cooking and processing methods can also impact the phytate content. For example, fermenting grains or beans can help break down phytates and increase iron absorption.

Personal experience-wise, I have noticed that when I consume a diet high in whole grains, beans, nuts, and seeds without considering iron absorption factors, my iron levels tend to be lower. However, by incorporating strategies to enhance iron absorption, such as pairing these foods with vitamin C-rich options or using fermentation techniques, I have been able to maintain adequate iron levels.

While grains, beans, nuts, and seeds are nutritious and beneficial in many ways, they do contain phytic acid, which can reduce iron absorption. By being mindful of this and employing techniques to enhance iron absorption, such as pairing these foods with vitamin C-rich options or using fermentation methods, you can still enjoy the health benefits of these foods while maintaining adequate iron levels.
