lautnusantara.com Fisheries play a very important role as a major source of protein, both globally and in Indonesia. Here are some key aspects of its role:

1. High-Quality Animal Protein Source
Fish is one of the best sources of animal protein available. Fish protein is known as a high-quality protein because:

  • Easy to Digest: Fish protein fibers are shorter than beef or chicken, making them easier for the body to digest, even for toddlers and people with digestive problems.
  • Complete Essential Amino Acids: Fish contains all the essential amino acids needed by the human body, which cannot be produced by the body itself and must be obtained from food. This includes taurine, which is useful for stimulating brain cell growth, especially in toddlers.
  • High Absorption: Fish protein has a high absorption rate by the body, reaching more than 90%.

2. Rich in Other Important Nutrients
In addition to protein, fish is also a "complete nutritional package" that provides various important vitamins and minerals:

a. Omega-3 Fatty Acids (EPA and DHA): This is one of the main advantages of fish. Omega-3 is vital for:

  • Heart Health: Lowers blood pressure, reduces bad cholesterol levels, and prevents the risk of heart disease and stroke.
  • Brain Development and Cognitive Function: Important for the brain development of fetuses, infants, and children, and helps maintain optimal brain function and prevent cognitive decline in adults and the elderly.
  • Eye Health: Helps repair eye cells and relieve inflammation.

b. Vitamins: Fish are rich in vitamin D (important for bones and regulating sleep cycles), vitamin A (for eye health), and various B vitamins (such as B6, B12, Niacin) which are important for metabolism and nerve function.
c. Minerals: Contains calcium, phosphorus (for bones and teeth), iron (prevents anemia), iodine (prevents thyroid disease), selenium (antioxidant), magnesium, and potassium.

3. Contribution to Food and Nutrition Security

  • Wide Availability: Indonesia as a maritime country has enormous fisheries potential, making fish a relatively accessible and affordable food source in many regions.
  • Economical Protein Alternative: Fish is often a more economical alternative to animal protein than red meat or poultry, especially in developing countries.
  • Community Nutrition Support: Regular fish consumption helps meet the recommended daily protein needs, contributing significantly to balanced nutrition, especially for children to prevent stunting and support optimal growth.

4. Overall Health Benefits
Regularly consuming fish has various health benefits, including:

  • Improving sleep quality.
  • Maintaining eye health.
  • Maintaining heart health.
  • Supporting brain function.
  • Increasing bone and joint strength.
  • Preventing thyroid disease.
  • Reducing the risk of chronic diseases.

Overall, fisheries are not only a food provider, but also a major pillar in meeting the protein and essential nutritional needs of billions of people around the world. Therefore, the sustainability of the fisheries sector is crucial for public health and global food security.
