Mineral Absorption Inhibition

Phytic acid in plant-based foods can bind to essential minerals in the gut, reducing their absorption and potentially leading to mineral deficiencies. This is more likely in individuals with low mineral intake or increased mineral needs.

Phytic acid, present in many plant-based foods, can strongly bind to essential minerals such as iron, zinc, calcium, and magnesium in the digestive tract. This binding action reduces the bioavailability of these minerals, meaning they are less readily absorbed by the body. Over time, this can lead to mineral deficiencies, especially in individuals with diets already low in these minerals or those with increased mineral requirements, such as pregnant women, growing children, and individuals with certain medical conditions. Symptoms of mineral deficiencies vary depending on the specific mineral affected, but can include fatigue, weakened immunity, bone problems, impaired cognitive function, and anemia. The severity and likelihood of mineral absorption inhibition depend on the quantity of phytic acid consumed, the overall mineral content of the diet, and individual factors influencing mineral absorption.
