And the US Food and Drug Administration (FDA) announced in mid-December of 2019 that fish oil capsules could be approved as an adjunct to prevent heart attacks, strokes, and death from cardiovascular diseases.

Where fish is a source of high-quality protein that is low in fat, salmon in particular plays an important role in preventing the risk of cancer because it contains vitamin D. A link has been found between the incidence of many types of cancer, including colon and breast cancer, and low levels of vitamin D. It has also been proven that fish contain “omega-3” works to delay or reduce the development of breast cancer and prostate cancer.
A Canadian study found that omega-3 fatty acids extracted from fatty fish (such as: salmon, tuna, mackerel, and sardines) have a stronger and more effective effect in preventing cancer than acids extracted from flax seeds and other oils. It works to fight cancer by turning on genes related to the immune system to suppress the growth pathways of cancerous tumors.

- Reduces stress levels in the brain after performing strenuous tasks.
- Enhances the action of neurotransmitters.
It was also found that the elderly eating fish and seafood at least once a week reduced their risk of developing Alzheimer’s and dementia, and it was found that those who ate fish regularly, had lower rates of depression than others. This study was supported by studies published in the journal “Neurology”, which indicated the role of “omega-3” in increasing the size of the area responsible for memory in the brain, which is consistent with the results of the previous study.
5. Protects against age-related hearing loss
Scientists have long considered the decline in the ability to hear with age is inevitable and cannot be stopped or reduced, but a recent study published in the “American Journal of Clinical Nutrition” concluded that eating fish significantly protects against hearing loss associated with age. age, because it is a rich source of “omega-3”.
