Research shows that eating wild fish is generally better for your gut microbiome than other animal proteins. The omega-3 fatty acids, fish protein, vitamin D, and chitin (found on small scaly fish) all benefit our gut microbiome’s Lactobacillus and butyrate content more than other animal proteins. Sardines, anchovies and wild salmon are some of the top fish to eat that are high in these nutrients and lower in mercury.
Selenium is a micronutrient found in Brazil nuts, but also naturally occurs in fish. Selenium will help your body naturally detox the mercury found in low-mercury fish.
Other studies have previously shown that people eating more non-fried fish, vs chicken or beef, had a reduced risk of colon cancer. And fish protein can also be used to lower blood pressure as part of a healthy diet.
Other animal proteins can be healthy as well when eaten in moderate amounts. Look for pasture-raised versions from your farmer. And always eat lots of green vegetables any time you eat protein – that combination is good for your system!
