Key Takeaways
Generally, we deal with insufficient iron levels in the body, leading to anemia. However, there are instances where the iron level exceeds the permissible limit, which is also detrimental to health and can cause negative health consequences. Iron is indispensable for the proper functioning of the organism and occurs in the form of hemoglobin, myoglobin, and mitochondrial enzymes [1].

Iron Overload Disorder (Primary and Secondary Hemochromatosis)
Hemochromatosis represents a metabolic disorder characterized by the pathological accumulation of iron within bodily tissues, a condition arising from dysfunctional regulatory mechanisms governing its homeostasis. The excessive deposition of this trace element in parenchymal organs—particularly the liver, pancreas, heart, and endocrine glands—leads to progressive cellular damage and, ultimately, organ failure. The disease manifests in two primary forms: **congenital (primary) hemochromatosis**, which is genetically determined and linked to mutations in the *HFE* gene (most commonly the homozygous C282Y mutation), and **acquired (secondary) hemochromatosis**, resulting from exogenous or endogenous factors. The most frequent causes of the secondary form include chronic blood transfusions, excessive iron supplementation, erythropoietic disorders (e.g., in thalassemia), and impairments in the synthesis of iron-transport proteins such as transferrin or hepcidin. Without appropriate therapeutic intervention, both forms can progress to severe systemic complications, including cirrhosis, type 1 diabetes mellitus, cardiomyopathy, or arthropathy [1, 2, 3].
Hereditary iron overload disorder: Clinical manifestations and associated symptomatic presentations
The clinical spectrum of this iron-overload disorder encompasses a multitude of systemic manifestations, including but not limited to: progressive hepatic parenchymal dysfunction culminating in liver failure, impaired myocardial contractility with an elevated risk of congestive heart failure, compromised glomerular filtration capacity leading to chronic kidney disease, persistent fatigue syndromes, and excessive daytime somnolence. Furthermore, the condition is frequently associated with fibrotic transformation of hepatic tissue progressing to cirrhosis, dysregulated glucose metabolism resulting in overt diabetes mellitus, a distinctive bronze or grayish hyperpigmentation of the skin (attributable to dermal deposits of both melanin and hemosiderin), inflammatory polyarthropathy affecting multiple joint structures, diminished gonadal hormone secretion with concomitant hypogonadotropic hypogonadism, and endocrine deficiencies spanning thyrotropin (TSH), follicle-stimulating hormone (FSH), adrenocorticotropic hormone (ACTH), luteinizing hormone (LH), as well as adrenal cortical steroids — findings substantiated by extensive clinical investigations and systematic reviews [1, 2, 3].
Primary hemochromatosis: evidence-based dietary guidelines for managing iron overload through nutrition
In the management of hereditary hemochromatosis, adherence to a low-iron diet represents a critical adjunctive therapeutic strategy, as substantiated by multiple clinical studies [1, 2]. The protocol necessitates strict limitation—or complete avoidance—of foods characterized by elevated concentrations of both heme and non-heme iron. High-risk items encompass red meats (particularly beef and pork), organ meats (liver, kidneys), whole-grain cereals (buckwheat, barley, quinoa), whole-grain bread and baked goods, root vegetables (beetroot), tree nuts (hazelnuts, almonds, macadamia nuts, cashews), seeds (sesame, pumpkin seeds), dark leafy greens (spinach, kale, Swiss chard, beet greens), cruciferous vegetables (broccoli, Brussels sprouts), and parsley. While dietary intervention alone cannot reverse disease progression, peer-reviewed evidence demonstrates that consistent adherence to these guidelines substantially diminishes iron burden, delays complication onset, and enhances patients’ long-term quality of life.
