The feeling of craving a particular food can occur due to psychological factors, physiological factors, or simply habit. For example, if you have a habit of eating popcorn while watching movies, you will automatically crave popcorn every time you watch a movie, according to the health website Healthline (USA).
Craving fish could be a sign that your body is lacking protein.
When we crave fish, the most common reason is our diet. People who are dieting, especially those cutting calories, are more likely to crave fish than usual. The main reason is a lack of protein.
"A diet lacking in protein will cause the body to crave protein-rich foods such as chicken, fish, and other meats," says American nutritionist Michael Lam.
Protein is a crucial macronutrient for health. We need protein for most bodily functions, from maintaining healthy nails, hair, and muscles to internal organs. Therefore, if you suddenly crave fish and have too little protein in your diet, the best way is to increase your protein intake with lean meats, eggs, dairy, and fish.
In some cases, cravings for fish have a psychological element. For example, you might like a particular fish dish because you ate it with your family when you were a child. This brings back fond memories, and it's perfectly normal to occasionally want to rediscover that flavor.
Currently, there is no scientific evidence to suggest that craving fish is linked to any disease or health problem. Therefore, if you crave fish, choose your favorite fish and enjoy it.
Eating fish offers numerous health benefits, especially fish rich in omega-3 fatty acids such as salmon, tuna, mackerel, and sardines. In general, both freshwater and saltwater fish contain many beneficial nutrients such as vitamin D, B12, calcium, iron, zinc, iodine, magnesium, potassium, and many others.
In fact, some believe that craving fish may be due to a deficiency in omega-3s or other nutrients like iodine. However, this hypothesis currently lacks convincing scientific evidence and requires further research.
According to Healthline , all the nutrients in fish help maintain a healthy heart, improve brain function, and reduce the risk of health problems such as inflammation, arthritis, diabetes, and dementia.
