Benefits
-
High in protein and fat to provide energy. The meat is leaner than many other red meats
-
Contains omega-3 fatty acids from its diet of mollusks and crustaceans. These fatty acids have anti-inflammatory properties
-
A good source of vitamins and minerals like niacin, vitamin B12, selenium and zinc
-
Subcutaneous fat provides insulation to help walruses withstand cold Arctic waters
-
Traditionally important to Alaska Native diets and culture
Risks
-
High in fat and calories. The fat content is over 50% which can contribute to weight gain and obesity if consumed in large amounts
-
High in cholesterol. Walrus meat and fat contains cholesterol which can increase risk of heart disease if eaten regularly
-
May contain environmental contaminants. As a marine mammal, walrus can accumulate toxins like mercury in their tissues through their diet. High levels of these contaminants over long periods of time can pose health risks
-
Risk of foodborne illness. As with any raw meat, walrus meat risks carrying bacteria that can cause diseases if not properly handled, stored and cooked
-
Limited nutrient content. While a source of protein, walrus meat is low in many essential vitamins and minerals. It should not be relied on as a primary source of nutrition without balancing with other foods
Additional Information
Walrus meat and subcutaneous fat, commonly consumed by Alaska Natives, offer unique nutritional benefits and risks. Let's explore these attributes of this food product.
Nutritional Benefits:
1. High Protein Content: Walrus meat is a rich source of high-quality protein. Protein is essential for growth, repair, and maintenance of body tissues, as well as the production of enzymes and hormones.
2. Omega-3 Fatty Acids: Walrus meat contains omega-3 fatty acids, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These essential fatty acids have been associated with numerous health benefits, including reduced inflammation, improved heart health, and brain function.
3. Vitamin B12: Walrus meat is an excellent source of vitamin B12, which is crucial for red blood cell production, nerve function, and DNA synthesis. Adequate intake of vitamin B12 is essential for maintaining healthy blood cells and preventing anemia.
4. Minerals: This food product is a good source of essential minerals such as iron, zinc, and selenium. Iron is vital for oxygen transport and energy production, while zinc and selenium play key roles in immune function and antioxidant defense.
5. Traditional Cultural Importance: For Alaska Natives, consuming walrus meat and subcutaneous fat is not only a source of nutrition but also holds cultural significance. It promotes traditional practices, community bonding, and preservation of cultural heritage.
Nutritional Risks:
1. High Cholesterol and Saturated Fat: Walrus meat and subcutaneous fat contain relatively high amounts of cholesterol and saturated fat. While these nutrients are necessary for certain bodily functions, excessive intake can lead to increased risk of heart disease and elevated blood cholesterol levels. It is important to balance their intake with other lean protein and healthier fat sources.
2. Environmental Contaminants: Due to their position in the food chain, walruses can accumulate environmental contaminants such as heavy metals (mercury) and persistent organic pollutants (POPs) like polychlorinated biphenyls (PCBs). These contaminants may pose health risks, especially if consumed in high amounts or over long periods. Pregnant women and children are particularly advised to limit their intake due to potential developmental risks.
3. Limited Availability and Accessibility: Walrus meat and subcutaneous fat are not widely available outside Alaska Native communities. This limited accessibility may restrict their inclusion in the diets of individuals who do not have access to these traditional food sources, potentially missing out on their unique nutritional benefits.
In conclusion, walrus meat and subcutaneous fat offer several nutritional benefits, including high protein content, omega-3 fatty acids, vitamin B12, and essential minerals. However, they also come with risks such as high cholesterol and saturated fat content, as well as potential exposure to environmental contaminants. It is crucial to balance the consumption of walrus meat and subcutaneous fat with a varied and balanced diet, considering individual health conditions and availability of alternative food sources.
