Eating fish can unlock a treasure trove of health benefits. One key advantage that followers of a pescetarian diet have over others is that it significantly boosts protein intake. Recommendations for fish intake vary, but generally, adults should consume at least two servings per week. However, many Americans primarily rely on chicken and other meats for protein, often due to accessibility and affordability. Despite this, health experts advise that fish should not be overlooked.Here’s why fish should be a staple in your diet Fish offers more than just impressive protein content and delicious taste. Fish, especially options like salmon, trout, mackerel, and cod, are excellent protein choices due to their omega-3 fatty acid content. Omega-3 help reduce inflammation, improve heart health and circulation, and support cognitive function.Omega-3 fatty acids play a vital role in overall health. They contribute to cell membrane structure, aid in creating brain signalling molecules, and support cardiovascular, neurological, and endocrine systems. Omega-3 fatty acids have long been associated with anti-inflammatory properties. Several decades of observational research have shown that higher fish intake is linked to a reduced risk of heart attacks, strokes, and all-cause mortality.Besides, fish oil is a popular dietary supplement derived from fatty fish like sardines, anchovies, mackerel, and salmon. The two primary omega-3 fatty acids in fish oil—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—are well-regarded for their heart health benefits, but their impact on the brain is equally significant, particularly in addressing issues like mild memory loss and depression. Another crucial nutrient found in fish is vitamin D. Salmon, tuna, mackerel, and trout are excellent sources of both vitamin D and protein. Nearly 42 percent of the U.S. population is deficient in vitamin D, as it is primarily obtained from sunlight and a limited number of foods.Additionally, fish is incredibly versatile. Many individuals grow tired of eating chicken, but fish provides a refreshing alternative. Season them in new ways, and experiment with different cooking methods. Fish is great baked, grilled, or pan-seared. Which Fish Are Best Protein Sources?Several types of fish rank among the highest in protein, according to the USDA Nutrient Database.

Protein is not only for your muscle building, but it has many other functions in your body. When they are digested, the proteins from the food are broken down into amino acids, which are the building blocks that can be rearranged to form any protein that the body may require. For instance, haemoglobin, enzymes, muscles, and keratin in our skin and hair are some of the forms of protein in our body among the 20,000 more proteins performing a wide range of functions in the human body.Factors like age, activity level, and health conditions influence the protein needs of an individual. According to US Dietary Guidelines, a sedentary adult should consume 0.8 grams of protein per kilogram of body weight.
