Research suggests that adequate intake of omega-3 fatty acids may help reduce symptoms of depression, anxiety, and mood disorders, as well as promote overall mental health.

Eye Health

Prawns contain the antioxidant astaxanthin, which provides several benefits for eye health. Astaxanthin belongs to the carotenoid family and has been proven by scientific studies to protect the eyes from oxidative stress and inflammation caused by free radicals. It helps reduce the risk of age-related macular degeneration (AMD), a leading cause of vision loss in older adults and supports overall eye health and visual acuity.

Nutrient Density

Prawns are a nutrient-dense food, meaning they contain a variety of essential vitamins and minerals necessary for optimal health. They are a good source of vitamin B12, which is essential for the production of red blood cells and proper nerve function. Prawns also provide vitamin D, a nutrient involved in calcium absorption and bone health, as well as vitamin E, an antioxidant that helps protect cells from damage. In terms of minerals, prawns are rich in iron. Research indicates iron is crucial for oxygen transport and energy production, and zinc, which supports immune function, wound healing, and DNA synthesis.

Weight Management

Prawns are relatively low in calories and fat while being high in protein. This nutrient composition makes them a favourable choice for weight management and maintaining healthy body weight. Research shows that protein is known to increase satiety and reduce appetite, helping control calorie intake and promote feelings of fullness. Including prawns in a balanced diet can support weight loss or weight maintenance goals.

Fertility and Reproductive Health

Prawns are a rich source of several nutrients that support fertility and reproductive health. Research indicates that omega-3 fatty acids EPA and DHA, along with zinc, vitamin E, and selenium found in prawns, are important for sperm production, quality, and motility in males. According to studies, these nutrients support hormonal balance, menstrual health, and fetal development during pregnancy in females. 

Summary

Prawns offer numerous health benefits, including being a high-quality protein source that supports muscle growth and maintenance. They promote heart health due to their low saturated fat and cholesterol content, along with omega-3 fatty acids that reduce the risk of cardiovascular diseases. Prawns containing omega-3 fatty acids contribute to brain function, improving cognitive performance and reducing the risk of cognitive decline. They also support mood and mental well-being. The antioxidant astaxanthin in prawns benefits eye health, protecting against age-related macular degeneration. Prawns are nutrient-dense, providing essential vitamins and minerals for overall health. They aid weight management, support fertility and reproductive health in both males and females.

Cooking and Preparing Prawns for Maximum Nutrient Retention

To maximize the retention of their valuable nutrients during the cooking process, it is essential to employ suitable cooking and preparation methods for prawns. Here are some tips to help you preserve the nutritional value of prawns:

Opt for Gentle Cooking Methods: Prawns are delicate and cook quickly, so it’s best to use gentle cooking methods that preserve their nutrients. Steaming, poaching, and grilling are excellent options as they require shorter cooking times and help retain more of the prawns’ natural flavours and nutrients. High heat and deep-frying methods can cause the oxidation of omega-3 fatty acids present in prawns, leading to potential nutrient loss.
