There are no specific foods that are directly "high" in hematocrit (HCT) levels. HCT represents the percentage of red blood cells in the total blood volume. However, a well-balanced diet that includes foods rich in iron, vitamins, and minerals can support healthy red blood cell production. Iron-rich foods like red meat, poultry, fish, leafy green vegetables (e.g., spinach, kale), legumes (e.g., lentils, beans), and iron-fortified cereals can help increase iron levels and support HCT. Additionally, consuming foods high in vitamin C (such as citrus fruits) can enhance iron absorption.
