Health Benefits of Tilapia fish

  1. Tilapia is non-oily, shallow water fish and is one of the lowest calorie fresh-water fish; 100 g holds just 96 calories; almost the same as halibut (91 calories).

  2. It is one of the finest sources of essential fatty acids, protein, minerals and fat-soluble vitamins like vitamin-A, E and D (cholecalciferol).

  3. Tilapia composes lean, white meat that composes good amino-acids profile. 100g fish provides 20.08 g/100 g (36% of RDI). Tilapia protein composition is complete in the sense that it has all the essential amino acids in good proportions.

  4. Its lean, white meat is also a good source of poly-unsaturated fatty acids (PUFA). Studies have shown that eating seafood can decrease the risk of heart attack, stroke, obesity and hypertension. Tilapia fat is less saturated but has lots of “heart healthy polyunsaturated fats, including omega-3 fatty acids.

  5. US FDA categorises tilapia in "the best choice" section considering mercury levels in its flesh. It recommends consumption of eat 2-3 servings a week for adults.

  6. Tilapia meat is good source of omega-3 eicosapentaenoicacid (EPA), docosapantaenoicacid (DPA) and docosahexaenoic acid (DHA) fatty acids. Studies suggest that that the fatty acids, particularly DHA, play an important role in the growth and development of nervous system, especially in infants and children.

  7. According to Cornell University and the New York Sea Grant Extension Program. 2012- the fatty acids play crucial role in decreasing blood pressure and heart rate and help improve cardiovascular function. For example, research has shown that omega-3 fatty acids decrease the risk of arrhythmias (abnormal heartbeats) that can lead to sudden death.

  8. In adults, several large trials have evaluated the effect of fish or fish oils on heart disease. In the "GISSI Prevention Trial heart attack survivors who took a 1-gram capsule of omega-3 fats every day for three years were less likely to have a repeat heart attack, stroke, or die of sudden death than those who took a placebo".

  9. 100 g of tilapia fillet holds -pyridoxine (B-6) 0.162 mg (12.5% RDA) of and niacin 3.903 mg (24% RDA). It is also a good source of vitamin-E, vitamin-B12, thiamin, and riboflavin.

  10. Sole fillet is naturally rich source of minerals including selenium (41.8 μg or 76% of DRI), iodine, calcium, zinc, potassium, phosphorus, and magnesium. Iodine is an important trace element in human nutrition and is essential for thyroid hormone synthesis.

In many Asian countries it is farmed in polluted rivers where water contains fish feces, rotting fish feed and residues of pesticides and veterinary drugs as well as other pollutants that were already mixed into the poor quality water supplied to farmers.

Tilapia fish has low mercury levels; 0.013 ppm. WHO tolerable upper limit of mercury in food is 0.5 mg/kg of fish. Accordingly, the U.S FDA final guidelines on how much fish expectant as well as breastfeeding mothers can eat, along with lists of specific options that are safe or should be avoided, places tilapia fish consumption under the best choice category. By this yardstick, they can consume 2-3 servings a week. (Medical disclaimer). Medical disclaimer).
