The belly - includes meat obtained from beef, sheep or pork stomach, is a traditional dish of Bulgarian cuisine, but is popular in all parts of the world with developed animal husbandry. In Mexico it is called machitos , in Scotland - haggis , in Spain - mondongo, and in distant Japan - horumonyaki . Wherever it is consumed, it is rich in vitamins and useful ingredients, according to a number of studies.
Measurements show that 100 g of raw belly contains only 85 calories, with an Indicative Daily Intake (RDA) of 2500 calories. It also contains over 12 g of protein, 3.6 g of fat and over 70 g of water. The amount of niacin or vitamin B 3 is only 0.8 g or less than 7% of ODP, but another B vitamin compensates enough: B 12 is represented by more than 1.39 mcg or almost 60% of ODP.
Vitamin B 12 is important for good blood circulation and a healthy nervous system . It improves the function of red blood cells, allowing them to carry oxygen more efficiently and maintains stable levels of myelin - a fatty compound that isolates nerve tissue and transmits nerve impulses.
100 g of belly also contains over 220 mg of choline . This dose corresponds to 52% of the ODP for women and 40% of the ODP for women. The human body uses choline to ensure normal tissue function, maintain healthy cell walls, and produce acetylcholine , a neurotransmitter and modulator responsible for good brain function. Choline helps the body metabolize fat faster, thus preventing the accumulation of fat in and around the liver .
Selenium is a major part of selenium proteins, which protect tissues from free radicals, promote cell growth, maintain thyroid function and regulate the activity of muscle cells . 100 g of tripe contains 14 mcg of selenium or 25% of ODP.
This product is also rich in the minerals phosphorus and zinc . 100 g of it contain 72 mg of phosphorus - 10% of ODP and 1.42 mg of zinc - 20% of ODP for women and 15% for men. Both minerals are important for cell membranes. Phosphorus is a component of the phospholipids on which the membranes depend, and zinc ennobles the proteins of these membranes. Phosphorus nourishes teeth and bones, and zinc nourishes the immune system.
