Iron deficiency is the most common nutritional deficiency on planet earth. Whenever serving as cytochromes to carry electrons within cells, facilitating oxygen storage in muscle and facilitating numerous enzymatic reactions in tissues dot 23 Iron deficiency can range from depleted iron stores without functional impairment to iron deficiency anemia, that affects a few organ systems, iron has numerous functions in the body including carrying oxygen to tissues. Zinc is a mineral that is an important component of numerous enzymes and plays an essential role in a few biochemical pathways. Most of us are aware that there are nine essential amino acids. Seriously. I’m sure that the nutritional characteristics of a protein depend on its amino acid composition. Whenever replicating DNA, transporting molecules and cell signaling, proteins perform a large array of functions including catalyzing metabolic reactions. Amino acids are the primary constituent of protein. Protein is a critical nutrient for human growth and maintenance of body tissues. In developed nations, macronutrient deficiency is very rare.
Both protein and essential fatty acid deficiencies result in cutaneous and nail disorders as these nutrients serve as building blocks for these structures. Protein and essential fatty acid deficiency occur more frequently than carbohydrate deficiency because of the high carbohydrate content of many foods. Numerous skin and nail changes result from macronutrient and micronutrient deficiency. Macronutrients include carbohydrates, fats and protein whereas micronutrients include vitamins and minerals. Normally, in developed countries, vitamin and nutritional deficiencies most commonly result from poverty, restrictive diets, medication, alcoholism and inadequate dietary intake in the ill and elderly. Recognition of skin and nail changes can be an important ol for diagnosing underlying nutritional deficiencies.
For instance, in developed countries, protein deficiency is most commonly associated with disease and advanced age. It’s a well proteinenergy malnutrition results from inadequate protein intake. Essential fatty acid deficiency is very rare as even small amounts of dietary intake can prevent deficiency. It’s an interesting fact that the two essential fatty acids are linoleic acid and alpha linolenic acid. Essential fatty acids are those that people must ingest as the body can not synthesize them. Biotin is a ‘water soluble’ B vitamin that acts as a coenzyme for essential reactions for fat and carbohydrate metabolism. Folate is required for light red blood cell production and DNA synthesis.
