Grouper benefits, and information on the different nutritional properties of this semi-fat fish, with ideal nutritional qualities in healthy and balanced diets.

The grouper is a fish belonging to the Serranidae family, which is also known by the name of cherna. It is a protected species, although with respect to the best months of the season in which it is possible to find them in the market and in fishmongers, it is practically throughout the year.

Although there are a good number of species that live in tropical seas, fundamentally it is a variety that is most consumed in many Spanish cuisines: the typical grouper of the Mediterranean Sea and the Atlantic Ocean.

Nutritional properties of grouper

The grouper is a semi – fat fish, which means that at certain times of the year its fat content makes it an oily fish, while at other times is a white fish.

100 grams of grouper provide 6 grams of fat and just about 120 calories, which means that we are facing a delicious fish ideal in balanced and healthy diets, low in fat and hypocaloric.

It provides an interesting amount of polyunsaturated and monounsaturated fats, and also a small amount of saturated fats.

It also provides minerals (such as phosphorus, magnesium and potassium) and vitamins (B complex vitamins such as B2, B3, B6, B9 and B12). Among the vitamins we can highlight the presence, although timid, of vitamin E, a very rare nutrient in fish.

Grouper benefits

Being a relatively low-fat fish, it becomes an extremely healthy food, which also provides  proteins of high biological value, which means that it contains most of the essential amino acids.

Regarding its vitamin content, we can highlight:

  • Vitamin B2: intervenes in enzymatic processes. In addition, it is essential for the skin and mucous membranes.
  • Vitamin B3: essential in taking advantage of the energy contained in macronutrients. It participates in turn in the production of sex hormones and in the synthesis of glycogen.
  • Vitamin B6: participates in the synthesis of macronutrients and in the formation of hormones, red blood cells and blood cells.
  • Vitamin B9: mostly known by the name of folic acid, it is essential for women who want to become pregnant (and not only during pregnancy), by helping to prevent defects in the placenta, and defects in the brain and spine in the fetus.
  • Vitamin B12: useful in the maturation of red blood cells, and in the proper functioning of neurons.
