As can be seen from the table, it provides significant amounts of fat-soluble vitamins, such as vitamin A, vitamin D, and vitamin E. These micronutrients are essential for healthy skin and muscle tissue.

In addition, without these vitamins, the body cannot synthesize hormones essential to increase fitness performance. A lack of vitamin D is directly related to low testosterone symptoms.

The Best Tuna – Fresh or Canned?

Fresh tuna is always going to be a better choice for fitness. In a muscle toning diet, it is fresh meats that should predominate.

Canned tuna usually has a high sodium content in its composition. Excess sodium chloride is harmful to cardiovascular health and increases the body’s fluid retention.

If you opt for canned tuna, try choosing it water-based and low in sodium. The cans of tuna in oil add a significant extra amount of calories with low nutritional value.

If you do not find another option in the market, opt for those that use olive oil; The last choice to buy should be cans of tuna in low-quality corn or sunflower oil.

Fish meat and testosterone

Research confirms a direct relationship between eating fish meats and testosterone (3,4).

A diet high in the meat of fatty fish such as tuna can help achieve a balance of fatty acids in the body and increase testosterone significantly.

In a study (3) with animals, it has been detected that the presence of eicosapentaenoic acid in some fish meats can stimulate the synthesis of the male sex hormone.

If this type of diet is also combined with a fitness activity, the results suggest that testosterone levels can increase up to 10%.

Tuna is a food that cannot be missing from a muscle toning diet. Including tuna meat in the list improves performance and endurance in fitness. The presence of fatty acids, the high protein content, and the low caloric content make tuna an excellent option for an athlete. In conclusion, tuna and fitness are a good combination.
