Farmed salmon: A sustainable animal protein when it comes to emissions As the planet warms and the global population grows, producing food as sustainably as possible is important. The National Oceanic and Atmospheric Administration reports that less than 2% of the world’s oceans are dedicated to aquaculture yet farmed salmon has the lowest carbon footprint of all animal proteins. This is because research from Johns Hopkins University found that farmed salmon — including salmon from Chile — contains more edible protein than other animals while requiring less feed and other inputs to grow.
This makes salmon’s environmental impact four times smaller than pork’s and eight times smaller than cattle’s. According to a 2018 analysis by the National Centre for Scientific Research, farmed salmon produces fewer greenhouse gas emissions per 100 grams of protein (5.98 kg) than beef (49.
9 kg). Salmon’s overlooked health benefits Chilean salmon is a nutritional powerhouse packed with high-quality protein and important nutrients, such as vitamin D and anti-inflammatory omega-3 fats. Research from the American Journal of Clinical Nutrition shows that eating fatty fish like salmon may decrease the risk for heart disease, some autoimmune conditions, depression and cognitive decline, while improving eye health and sleep quality.
Because of these many benefits, the USDA’s 2020 Dietary Guidelines recommend that Americans consume seafood two to three times per week, yet 80% of the a.
