Omega 3 is also beneficial for preventing certain cardiovascular diseases and increasing the levels of “good” cholesterol in the blood (HDL).

Canned fish are also an inexhaustible source of vitamin A, a nutrient that is essential to strengthen our entire immune system. All this while at the same time we will enjoy much stronger bones and teeth.
For its part, vitamin D improves the functioning of our nervous system and promotes the production of hemoglobin and red blood cells.
