5. Iron
Another thing that makes sardines so healthy is the fact that it contains a lot of iron. The most notable health benefit of iron is the fact that it increases your red blood cell count. This is due to the fact that the formation of red blood cells is actually reliant on your body having enough iron in the system. By increasing your red blood cell count, iron ensures that you won’t become anemic.
It also increases your overall energy level and staves off fatigue. If you often do a lot of taxing activities such as working late, going to the gym daily, or raising kids then getting enough iron is the best way to ensure that you’ll have enough energy for all these tasks. Remember, your body needs nutrients to get things done, and iron is like a high-octane fuel that can help it do just that.
