Nutritional value

Sea bass has a nutritional value similar to that of other lean fish. It’s one of the most consumed in several countries. In 2015, for instance, it accounted for 17% of the consumption of all animal protein. Let’s take a look at its nutritional composition based on 100 grams of the product.

  • Calories: 84
  • Protein: 18 grams
  • Fat: 1.3 grams
  • Iron: 1.1 milligrams
  • Iodine: 7 micrograms
  • Magnesium: 26 milligrams
  • Potassium: 340 milligrams
  • Phosphorus: 410 milligrams
  • Niacin: 6.7 milligrams
  • Vitamin B12: 4 micrograms

Sea bass meat provides just 1.3 grams of fat and has proteins of high biological value. It’s high in phosphorus and potassium. It’s also moderate in magnesium and iron.

The main vitamins it provides are niacin and B12 or cobalamin, whose content exceeds that of other fish species. The vitamin B12 content is even higher than that of other foods of animal origin, such as cheese, eggs, and red meat.

The properties and benefits of sea bass

The benefits of sea bass lie mainly in its nutritional value and the components that distinguish it. Below, we’ll take a look at them in detail.

Sea bass provides sufficient minerals in your diet

Sea bass provides several minerals that maintain the balance of many body functions. The most important are the following:

  • Potassium: This is one of the electrolytes that help muscle contraction and maintain a constant heart rate. It also allows nutrients to enter and leave the cells. It even favors the expulsion of toxins from the body. Nerve function depends on adequate levels of potassium and other minerals.
  • Iron: This is the raw material for making hemoglobin, a protein that forms part of red blood cells and transports oxygen from the lungs to the cells. It’s also part of myoglobin, which oxygenates muscles. This mineral is also used to produce hormones and connective tissue.
  • Phosphorus: Like calcium, phosphorus forms bones and teeth. It’s also a key element for the body to produce protein for growth, repair, and maintenance of tissues. In addition, it’s also involved in the metabolism of carbohydrates and fats, becoming a form of energy storage.
  • Magnesium: This mineral regulates the function of muscles and the nervous system. In turn, it’s involved in blood sugar levels and blood pressure. Among other things, it helps form protein, bones, and DNA.

It contains healthy fats

The fatty acids that make up the fat of sea bass are of the omega-3 type, which contributes to the prevention of cardiovascular diseases. Eicosapentaenoic (known as EPA), docosahexaenoic (DHA), oleic and palmitic fatty acids predominate in its meat.

EPA and DHA help lower LDL or “bad cholesterol” and increase HDL or “good cholesterol.” Incidentally, they also take care of eye health and are capable of improving intellectual capacities.

Sea bass concentrates good proportions of vitamin B12 and niacin

Sea bass contains appreciable amounts of cobalamin or B12 and niacin or B3, belonging to the B complex vitamins. According to the Scientific Information Journal, niacin participates in the metabolic reactions of oxidation-reduction for the body to obtain energy. It’s also part of the growth processes and the production of steroid hormones.

Meanwhile, cobalamin helps the body to transform food into sugar to be used as a source of energy. It also helps heal nerve cells, regulate the formation of red blood cells and control the increase in the amino acid homocysteine, which measures the risk of heart disease.
