Introduction:
Every cell, organ, and bodily function is powered by the robust network that is the human blood system. Blood is essential for immunological function, waste removal, and even cellular communication in addition to carrying oxygen and minerals. Red blood cells, white blood cells, platelets, and plasma are their fundamental constituents, and they all cooperate to maintain these vital processes. However, circulation is only one aspect of blood health; food also has a significant impact. Iron and vitamin K are essential nutrients that improve blood's capacity to carry oxygen, boost immunity, and control coagulation. The essential roles of blood and how nutrition can improve its effectiveness and general health will be discussed in this article.
What Are the Key Functions of Blood?
There are numerous functions of human blood, ranging from its transportation of absorbed nutrients, promoting or transporting oxygen within the body cells, elimination of metabolic wastes for excretion, molecular signaling or hormonal signaling and pathways, for transport of protein molecules and intracellular enzymatic and cell to cell communication in between even organ systems. Indeed we cannot imagine even the various sustaining and metabolic functions of human beings without the foundation of blood or the essential connective tissue source of the human circulatory system. Blood further is made of four major components as we know, that can help in the fulfillment of the above-enlisted functions.
While red blood cells, the main intrinsic part of the blood system or the erythrocyte cells transport oxygen to your cells, white blood cells or leukocytes are the immune defense mechanism of your body, the blood platelets that are the cell fragments aiding in the clotting and coagulation cascade or mechanism and lastly the blood plasma that is the fluid portion of your blood that contains several proteins, nutrients such as fat-soluble vitamins that aid in blood clotting process.
From the above-enlisted functions and the essential components of the human circulatory blood system, for supporting its renewal from time to time in your body, for boosting its metabolism, and for its vitality - diet and nutrition can indeed play one of the major regulators or role players in shaping your blood system immunity.
How Do Iron and Vitamin K Support Blood Health?
It is important according to current nutrition research to consume foods that can help replenish, renew, and sustain the vital functioning of blood to prevent not only anemias (a blood condition that happens when the blood's capacity to carry oxygen is diminished) or coagulation disorders but also in preventing the risk of organ system diseases, in preventing cardiovascular stroke or failure and in preventing neuromuscular deficiencies.
A. Iron:
Iron is one of the trace minerals, yet holds great value in the human circulatory system for the transport of oxygen, replenishing cell energy, immune functions, and antioxidant defense and also plays an essential role in neurocognitive functions and development, especially in children and young adolescents. The main function of iron as we know is its role in oxygen transport through the hemoglobin pigment or protein present in erythrocytes or red blood cells. When you do not consume a sufficient amount of iron - it can impact the hemoglobin levels directly as seen in different anemias or iron deficiency anemia particularly. For hemoglobin protein to be synthesized in sufficient amounts to fit the transport of oxygen to your cells and tissues, it is important to consume enough dietary sources of iron. You would mainly be deriving two types of iron via your diet: heme iron and non-heme iron.
-
Heme Iron: Heme iron is part of proteins like hemoglobin and myoglobin important to your blood protein metabolism, these are usually found in animal sources only. Heme iron is usually the most bioavailable iron source with 40 percent of animal foods comprising these sources such as fatty fish, poultry, and lean meats.
-
Non-heme Iron: Non-heme iron that is found in all plant-based foods usually is not a part of blood proteins like myoglobin or hemoglobin. However, be it the varied food groups of nuts, legumes, seeds, whole foods like grains, fruits, vegetables, fortified cereals, beans, or legumes, these are good sources to boost your iron intake dietarily. When you consume non-heme iron with vitamin C, it is deemed by nutritional experts to boost your bioavailability of iron intake. This is because non-heme iron is not as bioavailable to your body as heme iron. It is important to however not underestimate non-heme iron because current nutrition research shows that consumption of fiber-rich varied plant-based foods that are rich in non-heme iron can prevent the risk of chronic diseases, and help boost your polyphenol or antioxidant intake that can help boost blood immunity.
Balancing your dietary intake of both heme and non-heme iron is hence important for boosting your blood immunity. As of current nutrition research, the bioavailability for mixed diets (a combination of vegetarian and non-vegetarian foods) is approximately estimated to be around 14 to 18 percent, while it is around 5 to 12 percent for a vegetarian diet alone. Several high-risk population groups such as infants, children, pregnant and lactating individuals, and geriatric groups are at the highest risk for developing iron deficiency anemia. Hence these high-risk populations need more iron as recommended by the registered nutritionist or healthcare professional based on the age, gender, sex, and metabolic functions based on physical activity.
B. Vitamin K:
Subdivided into vitamin K 1 (phylloquinone derived from foods) and vitamin K2 (menaquinone) - these are the essential fat-soluble vitamins that you need to boost your blood metabolism and for sustaining health. These act mainly as coenzymes playing an important role in the coagulation cascade or clotting and also aid in the cellular and bone remodeling process of your body. Though the bioavailability of vitamin K for humans is unclear according to current nutrition research, vitamin K has been demonstrated to be largely synthesized by your large intestine bacterium. Though vitamin K deficiency is rare, in individuals with clotting disorders, anemias, immunocompromised individuals, gastrointestinal diseases like celiac disease, and newborns who are at high risk of vitamin K deficiency first few months of life - this fat-soluble vitamin is extremely important for blood clotting and in preventing hemorrhage.
So, what are the food sources recommended by nutrition experts for obtaining your dose of vitamin K to boost blood metabolism? These are usually the cruciferous greens that tend to have the highest concentration, such as broccoli, cauliflower, cabbage, etc., spinach and kale greens, collards, and turnips. Unrefined soybean and canola oil, in fact, is one of the currently recommended heart-healthy oils that are rich in vitamin K.
Conclusion:
Consuming food sources of iron and vitamin K, irrespective of the bioavailability factor, would still be one of the simplistic dietary ways by which you can boost your bodily blood metabolism and immunity. If you or your loved ones are suffering from any diseases related to your blood, or anemias or facing the clinical symptoms associated with it, your registered physician or nutritionist will chart your dietary needs of iron and vitamin K, as well as supplement you as per your nutritional requirements.
