• oz = 28.35 g (79.1 kcal)
• steak, excluding refuse (yield from 1 raw steak, with refuse, weighing 102 g) = 79 g (220.4 kcal)

• Vitamin B2 participates in oxidation-reduction reactions and promotes the colors’ receptivity by the visual analyzer and dark adaptation. Insufficient intake of vitamin B2 is accompanied by violation of the skin’s condition, mucous membranes, violation of light, and twilight vision.
• Vitamin B5 is involved in protein, fat, carbohydrate metabolism, cholesterol metabolism, synthesis of some hormones, hemoglobin, promotes the absorption of amino acids and sugars in the intestinal tract, and supports the adrenal cortex’s function. Lack of Pantothenic acid can lead to skin lesions and mucous membranes.
• Vitamin B12 plays an important role in the metabolism and conversion of amino acids. Folate and vitamin B12 are interrelated in vitamins involved in hematopoiesis. A lack of vitamin B12 leads to the development of partial or secondary folate deficiency and anemia, leukopenia, and thrombocytopenia.
• Vitamin PP participates in redox reactions of energy metabolism. Insufficient vitamin intake is accompanied by disturbance of the skin’s normal condition, gastrointestinal tract, and nervous system.
• Phosphorus takes part in many physiological processes, including energy metabolism, regulates the acid-alkaline balance, part of phospholipids, nucleotides, and nucleic acids, necessary for mineralization of bones and teeth. Deficiency leads to anorexia, anemia, rickets.
• Copper is part of enzymes with redox activity involved in iron metabolism and stimulates proteins and carbohydrates’ absorption—the processes involve providing tissues with oxygen. Deficiency is manifested by malformations of the cardiovascular system and skeleton, development of connective tissue dysplasia.
• Selenium – an essential element of the human body’s antioxidant defense system, has immunomodulatory effects, is involved in the regulation of the action of thyroid hormones. Deficiency leads to Kashin-Bek disease (osteoarthritis with multiple joint deformity, spine, and extremities), Kesan (endemic cardiomyopathy), hereditary thrombasthenia.
• Zinc is part of over 300 enzymes involved in the processes of synthesis and breakdown of carbohydrates, proteins, fats, nucleic acids, and the regulation of several genes’ expression. Insufficient intake leads to anemia, secondary immunodeficiency, liver cirrhosis, sexual dysfunction, presence of fetal malformations. Research in recent years revealed that high doses of zinc could disrupt copper absorption and thus contribute to anemia’s development.
