Although this oily fish has gotten a bad rep through the years as canned seafood with a pungent odor, sardines are actually a great nutrient-dense, low-calorie food. Packed with antioxidants, it also comes with many health benefits.

Great source of Healthy Fats

This oily fish is a rich source of "healthy" fats our body needs. Not only does the fish have heart healthy omega 3 fatty acids, it also has monounsaturated and polyunsaturated fats. Healthy fats can benefit the body in several ways, including:

  • Cancer prevention: Studies have suggested that intake of the omega 3 fats may slow tumor growth and improve the quality of life in cancer patients. Doctors may also suggest a diet high in the omega 3 fats as part of a preventative measure against cancer.
  • Strengthening the cardiovascular system: Fatty fish high in healthy fats have been linked to decreased risk of cardiovascular problems. Since it decreases blood cholesterol level, it also prevents heart attacks, strokes and high blood pressure.
  • Protecting the brain and nervous system: Omega 3 fatty acid is vital in supporting the brain and neurological systems, as much of it is found in the fats of the human brain. Studies have also shown that it can also decrease the risk of depression and slows the progression of schizophrenia in children.

Stronger Bone Health

Not only do sardines have great calcium content, they also have vitamin D. These two nutrients are essential in healthy bone growth and synthesis. In fact, vitamin D has been shown to aid calcium absorption, as it is commonly found in fortified dairy products. Phosphorus, another mineral present in sardines, is also important in strengthening the bone matrix with the help of vitamin B12.

Great source of Protein

For individuals who do not eat red meat, sardines are a great source of protein. Protein is important because it can provide the body with essential amino acids, which the body cannot spontaneously create, but needs for everyday functions. Indeed, protein is also great for muscle tissue wellbeing, as well as serving as the base components in connective tissues, antibodies and nutrient transporters in our body.
