Catfish is a type of freshwater fish that is found in many parts of the world. They are bottom-dwelling fish, meaning that they live and feed near the bottom of lakes, rivers, and streams. Catfish are known for their distinctive whiskers, which are actually sensory organs that help them navigate and locate food in murky water.
Catfish come in many different species, shapes, and sizes, but they are generally characterized by their smooth, scaleless skin and long, slender bodies. Some of the most common types of catfish include channel catfish, blue catfish, flathead catfish, and bullhead catfish.
Catfish are a popular food fish and are often fried, grilled, or baked. They are also a good source of protein and omega-3 fatty acids, which are important for heart health and brain function. However, it is important to be aware of potential contaminants in catfish that may be harmful to human health, especially if caught in polluted waters.
Benefits of catfish for health
Catfish is regarded as nutrient-rich since it is an excellent source of several nutrients yet low in calories. In reality, it could provide a lot of advantages.
Full of lean protein
One of your diet's main sources of energy is protein. Moreover, it is essential for the development and maintenance of muscle and tissue as well as the synthesis of several hormones, enzymes, and other substances.
Catfish, which has a serving size of 3.5 ounces (100 grammes), delivers 32–39% of the protein you need each day for just 105 calories.
For instance, the same amount of salmon has more than 230 calories but around half of your daily need for protein.
By increasing feelings of fullness, protein sources that are high in nutrients, like catfish, may promote weight reduction. Those who want to make sure they are receiving adequate nutrients while monitoring their calorie intake may consider this fish as well.
Omega-3 fatty acids are present.
Up to 8 ounces of fish or other seafood should be consumed each week, according to the U.S. Department of Agriculture (USDA).
This advice is given, among other things, since catfish and other seafood often contain more omega-3 fatty acids than other meals.
The benefits of omega-3 fatty acids for brain function are well known.
They may potentially aid in the treatment of neurological and mental problems including memory loss, attention deficit hyperactivity disorder (ADHD), and depression, however, more study is required in this area.
Omega-3s are also associated with increases in heart health, skeletal muscular strength, and even the gut microbiome, or a group of good bacteria in your gut.
A study of 23 studies involving more than 1 million participants found that eating fish was related to a decreased overall risk of mortality and that every 200 mg of omega-3 fatty acids daily was associated with a 7% lower risk of death.
As your body is unable to create omega-3s on its own, you must consume them via food. Catfish fillets weigh 3.5 ounces (100 grammes) and contain 237 mg, representing 15-20% of the Adequate Intake (AI) for adults.
Although catfish does contain omega-3 fatty acids, it is a leaner fish than rich fish like salmon and offers fewer fatty acids.
Compared to catfish, which only has 200 mg of omega-3s per 3-ounce dish, fatty fish like salmon may have up to 1,800 mg per serving.
A reliable supply of vitamin B12
3.5 ounces (100 grammes) of catfish has up to 121% of the daily value (DV) for vitamin B12, which many people need.
Although many fish are rich in this vitamin, catfish is an especially excellent source.
The prevention and treatment of anaemia, enhanced mental health, defence against heart disease, and other possible health advantages are all linked to adequate vitamin B12 levels.

This common fish has a terrific nutritional profile.
