Fish
Another good source of protein is fish. All varieties of fish are rich in protein. For instance, one cod fillet contains around 40 grams of protein, while one salmon fillet contains more than 60 grams of protein. In addition, fish provides the body with many essential minerals and vitamins, such as vitamin B12, selenium, and iodine. Studies have shown that high consumption of fish is linked to a reduced risk of certain health problems, such as type 2 diabetes and heart disease. Fatty fish, such as herring or salmon, are especially rich in omega-3, a form of healthy fatty acids that can benefit heart and brain health. [4]
