Can you eat fish every day?

In this brief guide, we will answer the query, “Can you eat fish every day?” We will also discuss what happens when you eat fish every day.

Can you eat fish every day?

Yes, in most cases you can eat fish every day. There may be a few exceptions like larger fish with longer lifespans, such as swordfish and tuna, should be avoided by pregnant women and children because they can contain higher levels of toxic elements, such as mercury. 

Eating fish every day is said to be a lot healthier than eating meat every day, so it can be very beneficial for you. However, since you’ll get enough nutrients from the fish if you consume it a few times a week, we can’t pinpoint if there are any added health benefits of eating fish every day. 

What happens when you eat fish every day?

Fishes are loaded with omega-3 fatty acids which provide you with numerous health benefits including improved brain and heart health. This is not all, eating fish every day can have many positive effects on your health, let us discuss them as follows:

Boosts your brain health

People who eat fish every day are more likely to have a healthy brain. Since fish is high in omega-3 fatty acids, adding more fish to your diet may benefit your brain functioning. According to the Global Organization of EPA and DHA Omega-3s, “Omega-3 intake is positively linked to a healthy brain.”

Furthermore, a study published in JAMA Neurology discovered that eating fish regularly can help manage the cognitive decline that occurs with age. According to the study, fish consumption was found associated with a slower rate of cognitive decline in different variables adjusted for age, gender, race, education, cognitive activity, physical activity, alcohol consumption, and total energy intake.

Boosts your eye health

Including fish in your daily diet is a great way to reduce your risk of age-related macular degeneration.

According to a study published in the American Journal of Clinical Nutrition, consuming fish every day can be a rich source of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which may reduce the risk of age-related macular degeneration. This does not mean that eating fish every day will magically increase your eyesight but it certainly prevents age-related macular degeneration.

Boosts your heart health

Several studies have linked daily fish consumption to a healthier heart and a lower risk of heart disease or failure. Regular consumption of fish may simply make you less susceptible to heart attacks or strokes. Also, regular fish consumption is linked to a reduction of the most common cardiovascular disease risk markers in an elderly population.

Improves baby’s health in pregnancy

Fish consumption has great health benefits during pregnancy but you have to be cautious of a few things. One thing you should be very careful about while eating fish during pregnancy is high mercury fish. They can have toxic effects on your as well as your baby’s health so it is important that you only eat low-mercury fish including salmon, sardines, and trout. 

Also, make sure that you are consuming no more than 12 ounces (340 grams) per week as naturally, fishes are high in mercury. A thoroughly cooked low mercury fish in limited quantity is recommended during pregnancy.

It May help to manage depression

Regular fish consumption is not just good for your physical health but also your mental health. According to a study published in Oxidative Medicine and Cellular Longevity, proper intake of omega-3 PUFA and dietary interventions including omega-3 PUFA supplements can provide relief to someone diagnosed with depression. 

Since fish is high in omega-3 fatty acids, consuming fish daily may reduce symptoms of depression and depressive episodes. So incorporate some fish into your everyday diet for your mental peace.

Prevents asthma problems

Fatty fish is loaded with omega-3 fatty acids. These fatty acids have anti-inflammatory effects on your body. One research demonstrated that eating fish twice a week significantly reduced lung inflammation in children with asthma. 

Furthermore, a study published in the journal PLOS One discovered that consumption of fish in pregnant women or infants is independently correlated with the development of asthma, especially in childhood.
